… as a first draft. We have much more to do trying to resurrect, if possible, some other inhouse PHP web applications we’ve based on the use of Zip in PHP. Pardon us, until tomorrow, while we have a little cry.

… as that “ahhhhhhhh, what a relief” reliever of tension running the RJM Programming website. The subtext is, our inode limits are a concern!
We think another lesson here is that PHP can be a good alternative to scripting languages such as Korn Shell to create “operational” procedures, especially when you consider that curl means it can be like writing your “surfing the net” type of PHP (slideshow_zero.php) work.

The recent Inhouse Slideshow Mobile Tutorial did not satisfy all the “mobile usability” tests performed by the “Google Crawl” algorithm, failing on “Content wider than screen”, and you can read some background to this with Google Crawl Viewport Geographicals Tutorial. And so we try some refinements here today, with an idea to control on mobile platforms the max-width CSS property of the document.body of a Inhouse Slideshow webpage, which made up the URLs failing this test at the Google Search Console.
We were reading this great and useful link, thanks, and decided to see whether this stopping of scrolling in X on mobile platform versions of the Inhouse Slideshow webpages gels better with Google Search Console “Google Crawl” Mobility Usability algorithms.
Yet again, deployment of these changes is similar to that last time, and the times before that, as per …

<meta http-equiv=”Content-Type” content=”text/html; charset=utf-8″>
<style>
td { vertical-align:top; }
</style>
change the h4 element to be h2 to help with legibility
iOS (ie. iPad and iPhone) PDF iframe elements have known scrolling issues, which we decided to bypass by opening these PDF creations in a new webpage window
Deployment of these changes is similar to that last time, and the times before that, as per …

… that little bit different in that a PDF Slideshow occupies just the one table cell (rather than the many horizontal cells of the other display modes) and the resultant embedded PDF data vertically scrolls when multiple image slides are involved.
This new option also adds onto this “Inhouse Slideshow” functionality the chance to download and keep a PDF representation of that slideshow to your local system. Perhaps this makes this be of interest to you?!
The changedform_creator.php‘s live run is what gets integrated into the “Inhouse Slideshow” “sisterhood”. We say “sisterhood” because this “Inhouse Slideshow” is designed as a single PHP codefile “hived off” to a lot of other web server folders as their default “index.php” web browser default webpage in a “peer to peer” feeling arrangement. Such an arrangement asks a bit of the deployment arrangements, and we’ve talked about this before (with underlying links pointing to today’s work, should you be interested) …

Have found that constructing slideshows with Paintbrush on a MacBook Pro for years have sometimes been saving what “file jpeg_filename.jpg” determines is a PNG, as a JPEG, which is not the end of the world as far as the browsers go rendering this. Within FPDF’s fpdf.php I fixed my own shortcomings that were resulting in “FPDF Error: Not a JPEG file” via the kludgy “if($a[2]==3) { return $this->_parsepng($file); }” additional codeline below …
… and this change to Fpdf’s fpdf.php fixed the issue in our case for a lot of our previously erroneous “PDF Slideshow” displays of “Inhouse Slideshows”.
PDF Slideshow and Form Creation Helper Primer Tutorial
Our recent work involving the great Fpdf creator of PDF files when we presented Ajax FormData Object No Body PHP PDF Tutorial has got us starting on a new PDF (PHP) web application we are starting out thinking will help with …
online forms (probably via thinking in terms of Fpdf open source programmers like Rick van Buuren and Clément Lavoillotte‘s excellent HTML table rendering ideas) via HTML table intermediate user interactions … and …
slideshows
… but we will not be surprised if the project branches out into other ideas. We’ll see over time.
We hope you come along for the trip starting with a bit of a proof of concept form_creator.php‘s live run for you to try, where we allow you to enter (and be able to change) some HTML table code (if that’s what you end up with?!) in a pink HTML textarea element, and that will become PDF should you click the underlying HTML form’s yellow submit button.
Hope to see you for tomorrow’s PDF writing developments here.

As soon as a web application talks about image slides, as we have been dealing with allowing for the creation of cartoons with our recent cowsay Python API / Command-line tool interfacing PHP web application, maybe as Louis Lumière did many years ago, it brings out media thoughts regarding “moving pictures”.

That last mode definitely needed a bit of attention, and it’s talents have come in handy with an extra non-mobile piece of functionality we’ve worked on today.

Google Chart Generic Background Image Collaboration Tutorial
We’ve fallen into an obsession with “c” words, and we apologize. Today’s “collaboration” came after yesterday’s Google Chart Generic Background Image Context Tutorial‘s “context” and before that “code”. What do we make of it?
Well?!

Thanks for the insights!

We have spent a day on email and SMS (conduit) sharing and collaboration means by which our non-mobile (only, so far) web users of the unaccounted for (after that Google Chart Pie Chart Background Image Tutorial inspiration from some time ago) Google Chart interfacing web applications can communicate. That work wasn’t as hard as we thought it would be, given the relief of location.hash hashtag URL methodologies whereby there is less worry about URL lengths regarding “a” link href “mailto:” and/or “sms:” sharing functionalities, so the mind must have wandered into the realms of …

We’ll be easing out the previous modus operandi in favour of this recent modus operandi over time, we’re thinking, but not before we have a day? looking into sharing functionality that might allow the user to share that Google Chart and its background image arrangements with an email recipient.
Google Chart Generic Background Image Code Tutorial
We were interested in a URL we detected being accessed, via our cPanel Apache Status report linking us to Google Chart Pie Chart Background Image Tutorial. Investigating this Google Charts interfacing PHP code means by which to allow for the user specification of background images, in the case of a Pie Chart, we realized some interfacings had been coded for this functionality, but not others.
But don’t we …

method=GET (the default) … to …
method=POST (when the URL becomes too long)
… and that new bit of logic is slated home to the generic external Javascript we have set aside for Google Charts work called gchartgen.js which changed for this work, in this way.
Maybe you can see how to use this feature yourself, and if that is the case you can try this live run link.
With this work, we’ve started refining the clipboard “smarts” by looking for linefeeds … in Javascript thoughts …
String.fromCharCode(10)
… and as the data exits the Javascript prompt window on its way, before navigating back to the PHP itself, we can check for too many fields to the right of the data, and truncate the clipboard data, as necessary. Along the way, we may be able to reject any header records with this same approach. We can check for no numerical fields here. Business specific logic can be applied here too. With a Pie Chart, the original data, or the user, may be tempted to place “%” after the numerical data, and we can take the opportunity to weed these out. Also, with the character data, it may be delimited by a double quote (ie. within “”), and with this knowledge in mind, we may be able to weed out confusing additional commas that could confuse us with the clipboard comma separated value format of the data.
The lesson here, is to “validate early” and it could be good to “validate often” as well. Real data can be strange indeed.
If you want to recreate the conditions as shown in today’s tutorial picture …

secondary data source, that you access … but today we are going to extend that functionality to support a …
primary data source that you enter a comma separated values list for the [place,lat,long] data sets (yourself, via the computer keyboard) … as well as a …
“subset” of a secondary data source, that you access, more than likely, using you computer device’s clipboard
The invention of the clipboard was a brilliant step. Before it, we were so beholden to programmers to get tailored work done, and though it’s sad that so many of you get on without us (cough, cough) … well … we were being overworked anyway … and there was that project to “make the morning breakfast coffee before you even know you wanted it” to get onto … finally.
Perhaps we all forget now what the clipboard has meant, for so many of us. It is the freedom of “copy and paste”, the individualism tool of content creation.
Yesterday’s functionality idea is a case in point. “Secondary data sources” are, by definition, out of your control, as to what the content of a web page is. Notice how, yesterday, we made some content that was (s)ftp transferred over to the rjmprogramming.com.au domain via … yes, you guessed it …
me copying (off the mapbox.com website, thanks, as part of the contents of a webpage) … then …
pasting that content into a csv text file on the MacBook Pro computer we’re using (locally) … and then …
(s)ftp transferred over to rjmprogramming.com.au domain to represent a …
But there you are, an intelligent human, able to determine for yourself the data you are interested in (quite often not the entire contents of a webpage, as yesterday’s work is ideally asking for), so that being the case, the map.php modifications to PHP code we’ve made today, make it possible for (the much simpler) …
me copying (off the mapbox.com website, thanks, as part of the contents of a webpage) … then …
If you have the clipboard as your friend, your time around computers becomes so much more enjoyable, and flexible, and within your control. We, as programmers, need to think, on occasions, or encourage, on occasions, how the user is likely to use the clipboard, in conjunction with our applications. As you might surmise, that can be a pretty unpredictable “artform”.
The last blog posting referring to the Google ChartMap Chart interface we host here was with Emoji Name Search Map Chart Weather Tutorial, but today we are presenting a major functionality addition with implications for other Google Chart interfacing PHP codesets here. We are allowing the user at the second prompt to take the data from a URL data source containing CSV (comma separated values) place,latitude,longitude data or those three fields in an HTML table element contents perhaps.
… could be a shortcut to that first URL same look. You can see another example using data from mapbox.com, thanks, show the scenario our tutorial picture illustrates.
The way this “mapping” (tee hee, tee hee) of URLs can happen is that the PHP supervisor map.php (changed this way and which you can try with this live run link) “includes” (ie. calls) …
include "../csv.php";
… a (now bigger, and more functional) csv.php (changed this way) does its best to handle a few looks to the CSV or tabular data, with code to allow for …
CSV data ordered place,latitude(decimal),longitude(decimal) or latitude(decimal),longitude(decimal),place or place,longitude(decimal),latitude(decimal) or longitude(decimal),latitude(decimal),place
CSV data ordered place,latitude(W/S/E/N_deg_min_secs),longitude(W/S/E/N_deg_min_secs) or latitude(W/S/E/N_deg_min_secs),longitude(W/S/E/N_deg_min_secs),place or place,longitude(W/S/E/N_deg_min_secs),latitude(W/S/E/N_deg_min_secs) or longitude(W/S/E/N_deg_min_secs),latitude(W/S/E/N_deg_min_secs),place
HTML tabular data ordered place,latitude(decimal),longitude(decimal) or latitude(decimal),longitude(decimal),place or place,longitude(decimal),latitude(decimal) or longitude(decimal),latitude(decimal),place
HTML tabular data ordered place,latitude(W/S/E/N_deg_min_secs),longitude(W/S/E/N_deg_min_secs) or latitude(W/S/E/N_deg_min_secs),longitude(W/S/E/N_deg_min_secs),place or place,longitude(W/S/E/N_deg_min_secs),latitude(W/S/E/N_deg_min_secs) or longitude(W/S/E/N_deg_min_secs),latitude(W/S/E/N_deg_min_secs),place
… am sure you’ll have noticed how bottom heavy it is on the “child” as far as functionality goes. What we like to call “the hard working duck syndrome”. Partly, that is because we see the Google ChartsMap Chart interface we have as being a very useful “meeting point” with interfacing web applications tending towards the “where” of life.
Today’s job, extending yesterday’s Emoji Name Search Map Chart Tutorial is to add Map Chart interfacing to the great Weather Underground and its great API service for autocomplete name searches for weather (and hurricane) information … thanks.
The changes are again just to that “hard working duck” Map Chart interface “child” web application, as for yesterday’s work. We were very keen to do this, especially because …
Weather Underground database works most succinctly with Placename, Country identification pairs, better than for the …
Continent/Placename setup of (PHP) Timezones
… and so, while we are going to so much trouble scouring Timezone places for their associated Countries, it is a really good opportunity to slot in some Weather API interfacing to our Emoji World Flags web application, which is starting to be looking better and better as a trip planning aid.
… all made so very possible when web applications sit in the same domain and you utilize the HTML iframe element.
We wanted to enhance its integration by …
adding in “locality pins” for all PHP Timezone places in the country of interest
involving Emoji flags in the Map Chart title (rather than as a pin) because Emojis, after all, are like textual data, not HTML (but can use HTML Entity representations in both)
To work the latter of these we called on recent experience with the “Fifth Beatle” discussion in Emoji Name Search Primer Tutorial …
We got quite excited recently with Rainbow Games PHP Emoji Tutorial when we added a (fourth Beatle) emoji helper, called Emoji Terra, into the mix of tools to gather emoji information. Today, we’ve got a new Emoji Search web application that introduces a new (fifth Beatle(?)) emoji helper tool to add into the “how we see it” mix …
We found that Emoji Terra could be used in our map Chart interfacing PHP to look up the HTML Decimal Entity for a flag of a country via the URL pattern …
So even though Google Chart Map Charts do not allow HTML in their titles there is nothing stopping you putting in an HTML Entity Emoji coding.
As far as the former goes, we again called on the PHP DateTimeZone class to scrutinize the first Timezone in the Map Chart title, derive its ISO 2 letter Country Code, and look through the array list of (PHP) Timezones to garner latitude and longitude, time now, and GMT offset information necessary to improve the “where” and “when” aspects of our Google Chart Map Chart interfacing.
Yesterday’s Emoji Name Search Map Tutorial was a step in the direction of “where” functionality, but because PHP teams up with the supervisory HTML “Emoji World Flags” web application, to make all this happen, there is the opportunity to add interest by adding a “when” aspect to how it works.
As we’ve said many times now, should you have access to PHP, you also have access to its DateTimeZone class where Timezones can be linked to ISO 2 letter Country Codes, useful as an integration point as of recent times when we introduced ISO 2 letter Country Codes to today’s (supervisory) live run‘s world_flags.html HTML and Javascript code.
Yesterday’s posted data Emoji Name Search Posting Tutorial functionality opened the door to “where” web application (software) integration, because the wonderful Wikipedia has compiled Latitude,Longitude co-ordinate pairs for those countries, and that is our foot in the door to place an HTML a link under the Emoji flags, that points to our favourite “where” interfacing tool, the Google ChartsMap Chart.
Because the Map Chart and Emoji Flag web application share the same domain we can keep this functionality on this same Emoji Flag webpage in an …
HTML iframe element name=gcmiid=gcmi initially invisible … “populated by” …
HTML a element target=gcmihref=[URL to Map Chart for Country of Interest]onclick=aoc(); …
function aoc() {
document.getElementById('gmci').style.width='450px';
document.getElementById('gmci').style.height='450px';
document.getElementById('gmci').style.display='inline-block';
}
Yesterday’s Emoji Name Search Tailoring Tutorial was suitable for data sets of that smaller size able to be handled by the web server limit of URL length. But what if there are too many data items in your data set to be handled by PHP’s $_GET[] array URL ? and & delimited URLs? We, having PHP serverside code at our disposal, can turn to $_POST[] (HTML) method=POST form action=[here’sLookingAtYouKid] scenarios, to get around this issue. The unfortunate side effect of this is that the HTML mailto:a link (email client) method of sharing your Emoji web application relies on that $_GET[] approach, that is, unless you wrote a whole “bespoke” web application to help out, like we do today for our new Emoji “World Flags” web application with this live run, with this HTML and Javascript world_flags.html source code.
That new “supervisor” being a guinea pig idea into the $_POST[] thinking, we add some HTML form element input type=text additions to allow for, out of …
Emoji look class … and …
Wording next to Emoji … and …
URL of Wording’s link, be that substituted or appended
… mapped values, optionally, off a newly offered HTML form element input type=text for this mapped comma or blank separated word list.
Perhaps, now, you “long data set thinkers” want to try the live run and/or its PHP source code emoticon_keyboard_shortcuts.php changed in this way to extend its data set size capabilities.
Information Technology is full of “buzz words”, and am sure you wince at some to all of them yourselves. That’s a bit why am using “Tailoring” rather than …
sharing
personalization
… to give you a slumberrest from having to look under struck throughdeleted wording to look for hidden “buzz words”terminology that makes your harehair sit upstand watchingon Bugs Bunnyend.
We think, perhaps, that emojis can be important for young “would be” programmers to launch into. Personally wonder how many “would be” programmers give the game up far too soon just because they don’t have those graphics skills, well, with emojis, a lot of that hard work, in miniature, has been done for you by some pretty creative people, so why not enjoy the fruits (chortle, in context, chortle) of their labour and start developing your own web applications to use them. Daily, their use is increasing, as are the sharing of access methods.
In today’s extension to the functionality started with yesterday’s Emoji Name Search Primer Tutorial we separate the Emoji Terra aspects to how it works and allow the user to …
supply an Emoji Word List of interest
perhaps supply a heading and subheading to describe the “concept” of that list
supply either a …
URL prefix … or …
URL with the ~ (tilde) character where you want, substituted, your emoji name
… to be a navigation destination in that similar new window navigation we used to access Emoji Terra …
presenting all this in an HTML form action=[here’sLookingAtYouKid] method=GET …
that method=GET opening the door to be able to offer an email client engine method to “share”email somebody the link to a screen that looks like the one you’re seeing
Of course, we’d like you to find some of your own such Emoji Display Dynamically Created Web Applications yourself, but to encourage, we, in the web application, today, identified two ideas, namely …
Astrology via Cafe Astrology at https://cafeastrology.com/~dailyhoroscope.html via ~ (tilde) character substitution
… each of which (and any you make will also) feature a link to the HTML mailto:a link out through the email client and to your recipient who can click the email link to “share”compare notes.
Perhaps, now, you want to try the live run and/or its PHP source code emoticon_keyboard_shortcuts.php changed in this way to extend its functionality, involving a reveal favourite of ours, the use of HTML(5)’s details (and summary) element.
We got quite excited recently with Rainbow Games PHP Emoji Tutorial when we added a (fourth Beatle) emoji helper, called Emoji Terra, into the mix of tools to gather emoji information.

Emojipedia is good for looking up Emoji names or concepts in words
FileFormat Information is great for HTML Entity determinations for your less complex Emojis
Iemoji is great for HTML Entity determinations for Emojis of all complexities
Emoji Terra performs similar functionality as Iemoji but has a permalink organization more friendly to an “emoji search via emoji title” query, and that has suited our purposes today, and before, so, thanks a lot
Emoji CSS performs similar functionality to Emojipedia, but has a pictorial view of Emoji names as well, right from the word go, thanks
With these emoji tools in mind we wrote a new PHP web application combining those last two to show Emojis pictorially (with their short name) initially and allow the user to search for an Emoji (match) list via their HTML input type=text (textbox) entry, which results in …
the Emoji (match) list look (as an Emoji “display”) … and …
an HTML a link which is that Emoji’s short name … linking to …
an Emoji Terra webpage with more detail, including HTML Entity information if “short name” is unique, or one extra click away, if not
In order to take that further genericization step onto the achievements of yesterday’s Rainbow Games Genericization Tutorial to get onto (the mathematics Induction principle inspired) …
prove for the first case

… we had a choice of …
continue on (with) the HTML code creation of new “hardcoded” arrays (managed by Javascript eval abstractional approach) … or “bite the bullet” and …
try to work out a generic “emoji lookerer upperer” arrangement
Guess you can tell we opted for the latter, huh?! We started the investigation of this by examining our three favourite emoji informational websites, namely …
… and were a bit surprised that we could not quite swing a generic method to glean the information, so don’t know whether our new “player” is “Ringo Starr” or not, but can tell you this, “its beat is much better than its bite” … chortle, chortle …
Emoji Terra performs similar functionality as Iemoji but has a permalink organization more friendly to an “emoji search via emoji title” query, and that suits our purposes today, so, thanks a lot. Without this query by “emoji title” possibility we’d have been forced to adopt more of those “hardcoded” arrays, which would have been alright, but this second approach opens the door to “sport” events in “The Rainbow Games” web application using emojis of the future (ie. they haven’t been invented yet).
amend that HTML source to supplant the “Sprint” default sport for this new nominated sport … trying not to fall over laughing at some of the new sports we present (inspired by a visit to Emoji Terra search)
write out that amended HTML code as the web page (the beauty of a serverside language like PHP)
The more detailed specifics of the file_get_contents of Emoji Terra lookup above are …
build up a URL starting with HTTP://emojiterra.com/ … then …
in emojiland arrangements there are two genders (as our prefixes if you will) … woman- and man-
then add on a “middle” sport descriptor (eg. biking)
in emojiland emoticonland arrangements there are five descriptors (as our suffixes if you will) … -dark-skin-tone, -medium-dark-skin-tone, -medium-skin-tone, -medium-light-skin-tone, -light-skin-tone
for that set of 2x1x5=10 URLs glean what “HTML dec” (HTML Entity) information you can glean via the file_get_contents call of the Emoji Terra URLs described above (eg. Emoji: Woman Biking: Dark Skin Tone) … built into a Javascript array string to “plug into” the previously read HTML partner source code, and amended to output as the web page the user sees
Again, in honour of “onions of the 4th dimension” approaches, we mainly, turn to the power of Javascript’s eval methodology to achieve this abstracted feeling to our web application. Today, with this, we go two thirds of the way along the “Mathematical Induction” approach …
prove for the first case
prove for the second case
prove for the nth case
How does this use of Javascript eval manifest itself in this way?
there are two arrays that work with the “content” of our “Rainbow Games” sport(s) (well, at least, the first “sprint running” sport) called emoticons[] and choices[]
wherever we find references in the code to either of these two arrays we start to involve the global variable verbsuffix …
var verb='Sprint';
var verbs=['Sprint','Row'];
var anotherverb='run'; var verbsuffix='';
… in altered ways like …
function plus(ih,ihep) {
var outihep=ihep;
if (eval("emoticons" + verbsuffix + "[" + ih + "]").indexOf('<p>') != -1) {
outihep += ' (' + eval("emoticons" + verbsuffix + "[" + ih + "]").split('<p>')[1].split('<')[0] + ')';
}
return outihep;
}
… in that abstracted way … noting that sometimes you don’t need the “eval()” encasings …
and so, working through the code this way it just falls to the coder to define new members for all the arrays for all the new sports (ours is “rowing” today), some of those new arrays (like for rowing are emoticonsrowing[] and choicesrowing[]) to involve …
make sure the event logics work for multiple sport scenarios … but mostly they do by sticking to the principles above … especially for the …
new HTML select (dropdown) element allows the user to pick a sport
Remaining a work in progress, you can try out our live run link that has underlying HTML and Javascript and CSS emoji_walk_animation.htm, and which changed in this way regarding today’s genericization work. We hope it gives you food for thought.
We were on the “road to personalization” for the web application game we started with yesterday’s Rainbow Games Primer Tutorial when “an old chestnut” came up again. It’s happened before, the desire to “double transform” in CSS came about from our emoji …
… necessary to make our running emojis run from left to right (that, alas, also transformed any accompanying …

mirror (image) flip the table cell (td) emoji data … but us appending some “Runner Name” textual data underneath also, annoyingly, got flipped until …
within that (same) table cell (td) element and after the emoji data we append an HTML p(aragraph) element to both …
introduce a new HTML element type into the (CSS styling) mix … and to …
introduce a new CSS transformation type, the matrix … perhaps either or both new parts to the problem critical to its success when, believe me, lots of other approaches don’t work
… to personalize the “runners” and “users”, optionally, “into the game”, by allowing the “user” to name their “runners” and allow for a “runner energy” setting be a bit randomized, to add for some other interest “variety” to the game’s workings. So, still a work in progress that you can try out at our live run link that has underlying HTML and Javascript and CSS emoji_walk_animation.html, and which changed in this way regarding today’s work.
It’s been a while since we’ve written any conventional HTML and Javascript and CSS game. Today’s game uses the “emoticon” section of the Emoji character set, defaulting so far, to the “running woman” emoji featuring in Compound Emoji WordPress Usage Tutorial.
It’s the early days of our “Rainbow Games” web application, and we’re starting with the animation featuring horizontal hashtag navigation techniques for a running race start to our game. Where it finishes? Hard to say! Today, we’ve looked at “splits” and a finish line.
As well, before that, into the generic code, we made some styling improvements to hide some unnecessary elements for mobile platform usage, and improved form sizing to reduce the need for scrolling, as well as email and SMS conduit logic improvements. We hope you enjoy trying out some of these PHP web applications with background images of your choosing.

… that we’d been limiting our scope to up until today. On mobile platforms we arrange for an overlaying HTML form to override the window.prompt, meaning webpage calls differ for each question asked of the user. This asks for quite a difference architecture to our coding requirements.
Google Chart Generic Background Image Collaboration Tutorial
We’ve fallen into an obsession with “c” words, and we apologize. Today’s “collaboration” came after yesterday’s Google Chart Generic Background Image Context Tutorial‘s “context” and before that “code”. What do we make of it?
Well?!
…
Thanks for the insights!
We are not robots here at RJM Programming, but believe it or not, having three acrostically identical tutorial titles in a row causes us more consternation than usual (Nala’s practically apoplectic), even beyond those butterflies in Brazil crossing the equator and affected by the Coriolis Effect. Anyway …
We have spent a day on email and SMS (conduit) sharing and collaboration means by which our non-mobile (only, so far) web users of the unaccounted for (after that Google Chart Pie Chart Background Image Tutorial inspiration from some time ago) Google Chart interfacing web applications can communicate. That work wasn’t as hard as we thought it would be, given the relief of location.hash hashtag URL methodologies whereby there is less worry about URL lengths regarding “a” link href “mailto:” and/or “sms:” sharing functionalities, so the mind must have wandered into the realms of …

… and output image data via URL calls that do not have to “end with the extension of any image file”. Our WordPress blog’s TwentyTen theme’s 404.php is capable of this with URLs such as …
As you might imagine, we wanted to get these two ideas into the mix, especially as it was nagging away at us that the user interaction to make any of this work happen is asking a lot of the web user out there, but to involve more (potentially, later, mobile) users to get interested we can now …

… making for a better end result set. But there’s more. We’ll be easing out the previous modus operandi in favour of this recent modus operandi over time, we’re thinking, but not before we have a day? looking into sharing functionality that might allow the user to share that Google Chart and its background image arrangements with an email recipient.
Google Chart Generic Background Image Code Tutorial
We were interested in a URL we detected being accessed, via our cPanel Apache Status report linking us to Google Chart Pie Chart Background Image Tutorial. Investigating this Google Charts interfacing PHP code means by which to allow for the user specification of background images, in the case of a Pie Chart, we realized some interfacings had been coded for this functionality, but not others.
But don’t we …

wish to apply opacity just to background image, but not the corresponding textual data (or other types) that is the primary content of that HTML element
You can see a video of some of the practicalities to usage on an iPad mobile app version in the YouTube video below …
Because data URIs are an option here, too, you will see in the code changes to pie_chart.php the need, now, to cater for the switch of HTML form navigation from …
method=GET (the default) … to …
method=POST (when the URL becomes too long)
… and that new bit of logic is slated home to the generic external Javascript we have set aside for Google Charts work called gchartgen.js which changed for this work, in this way.
Maybe you can see how to use this feature yourself, and if that is the case you can try this live run link.
With this work, we’ve started refining the clipboard “smarts” by looking for linefeeds … in Javascript thoughts …
String.fromCharCode(10)
… and as the data exits the Javascript prompt window on its way, before navigating back to the PHP itself, we can check for too many fields to the right of the data, and truncate the clipboard data, as necessary. Along the way, we may be able to reject any header records with this same approach. We can check for no numerical fields here. Business specific logic can be applied here too. With a Pie Chart, the original data, or the user, may be tempted to place “%” after the numerical data, and we can take the opportunity to weed these out. Also, with the character data, it may be delimited by a double quote (ie. within “”), and with this knowledge in mind, we may be able to weed out confusing additional commas that could confuse us with the clipboard comma separated value format of the data.
The lesson here, is to “validate early” and it could be good to “validate often” as well. Real data can be strange indeed.
If you want to recreate the conditions as shown in today’s tutorial picture …

secondary data source, that you access … but today we are going to extend that functionality to support a …
primary data source that you enter a comma separated values list for the [place,lat,long] data sets (yourself, via the computer keyboard) … as well as a …
“subset” of a secondary data source, that you access, more than likely, using you computer device’s clipboard
The invention of the clipboard was a brilliant step. Before it, we were so beholden to programmers to get tailored work done, and though it’s sad that so many of you get on without us (cough, cough) … well … we were being overworked anyway … and there was that project to “make the morning breakfast coffee before you even know you wanted it” to get onto … finally.
Perhaps we all forget now what the clipboard has meant, for so many of us. It is the freedom of “copy and paste”, the individualism tool of content creation.
Yesterday’s functionality idea is a case in point. “Secondary data sources” are, by definition, out of your control, as to what the content of a web page is. Notice how, yesterday, we made some content that was (s)ftp transferred over to the rjmprogramming.com.au domain via … yes, you guessed it …
me copying (off the mapbox.com website, thanks, as part of the contents of a webpage) … then …
pasting that content into a csv text file on the MacBook Pro computer we’re using (locally) … and then …
(s)ftp transferred over to rjmprogramming.com.au domain to represent a …
But there you are, an intelligent human, able to determine for yourself the data you are interested in (quite often not the entire contents of a webpage, as yesterday’s work is ideally asking for), so that being the case, the map.php modifications to PHP code we’ve made today, make it possible for (the much simpler) …
me copying (off the mapbox.com website, thanks, as part of the contents of a webpage) … then …
If you have the clipboard as your friend, your time around computers becomes so much more enjoyable, and flexible, and within your control. We, as programmers, need to think, on occasions, or encourage, on occasions, how the user is likely to use the clipboard, in conjunction with our applications. As you might surmise, that can be a pretty unpredictable “artform”.
The last blog posting referring to the Google ChartMap Chart interface we host here was with Emoji Name Search Map Chart Weather Tutorial, but today we are presenting a major functionality addition with implications for other Google Chart interfacing PHP codesets here. We are allowing the user at the second prompt to take the data from a URL data source containing CSV (comma separated values) place,latitude,longitude data or those three fields in an HTML table element contents perhaps.
… could be a shortcut to that first URL same look. You can see another example using data from mapbox.com, thanks, show the scenario our tutorial picture illustrates.
The way this “mapping” (tee hee, tee hee) of URLs can happen is that the PHP supervisor map.php (changed this way and which you can try with this live run link) “includes” (ie. calls) …
include "../csv.php";
… a (now bigger, and more functional) csv.php (changed this way) does its best to handle a few looks to the CSV or tabular data, with code to allow for …
CSV data ordered place,latitude(decimal),longitude(decimal) or latitude(decimal),longitude(decimal),place or place,longitude(decimal),latitude(decimal) or longitude(decimal),latitude(decimal),place
CSV data ordered place,latitude(W/S/E/N_deg_min_secs),longitude(W/S/E/N_deg_min_secs) or latitude(W/S/E/N_deg_min_secs),longitude(W/S/E/N_deg_min_secs),place or place,longitude(W/S/E/N_deg_min_secs),latitude(W/S/E/N_deg_min_secs) or longitude(W/S/E/N_deg_min_secs),latitude(W/S/E/N_deg_min_secs),place
HTML tabular data ordered place,latitude(decimal),longitude(decimal) or latitude(decimal),longitude(decimal),place or place,longitude(decimal),latitude(decimal) or longitude(decimal),latitude(decimal),place
HTML tabular data ordered place,latitude(W/S/E/N_deg_min_secs),longitude(W/S/E/N_deg_min_secs) or latitude(W/S/E/N_deg_min_secs),longitude(W/S/E/N_deg_min_secs),place or place,longitude(W/S/E/N_deg_min_secs),latitude(W/S/E/N_deg_min_secs) or longitude(W/S/E/N_deg_min_secs),latitude(W/S/E/N_deg_min_secs),place
… am sure you’ll have noticed how bottom heavy it is on the “child” as far as functionality goes. What we like to call “the hard working duck syndrome”. Partly, that is because we see the Google ChartsMap Chart interface we have as being a very useful “meeting point” with interfacing web applications tending towards the “where” of life.
Today’s job, extending yesterday’s Emoji Name Search Map Chart Tutorial is to add Map Chart interfacing to the great Weather Underground and its great API service for autocomplete name searches for weather (and hurricane) information … thanks.
The changes are again just to that “hard working duck” Map Chart interface “child” web application, as for yesterday’s work. We were very keen to do this, especially because …
Weather Underground database works most succinctly with Placename, Country identification pairs, better than for the …
Continent/Placename setup of (PHP) Timezones
… and so, while we are going to so much trouble scouring Timezone places for their associated Countries, it is a really good opportunity to slot in some Weather API interfacing to our Emoji World Flags web application, which is starting to be looking better and better as a trip planning aid.
… all made so very possible when web applications sit in the same domain and you utilize the HTML iframe element.
We wanted to enhance its integration by …
adding in “locality pins” for all PHP Timezone places in the country of interest
involving Emoji flags in the Map Chart title (rather than as a pin) because Emojis, after all, are like textual data, not HTML (but can use HTML Entity representations in both)
To work the latter of these we called on recent experience with the “Fifth Beatle” discussion in Emoji Name Search Primer Tutorial …
We got quite excited recently with Rainbow Games PHP Emoji Tutorial when we added a (fourth Beatle) emoji helper, called Emoji Terra, into the mix of tools to gather emoji information. Today, we’ve got a new Emoji Search web application that introduces a new (fifth Beatle(?)) emoji helper tool to add into the “how we see it” mix …
We found that Emoji Terra could be used in our map Chart interfacing PHP to look up the HTML Decimal Entity for a flag of a country via the URL pattern …
So even though Google Chart Map Charts do not allow HTML in their titles there is nothing stopping you putting in an HTML Entity Emoji coding.
As far as the former goes, we again called on the PHP DateTimeZone class to scrutinize the first Timezone in the Map Chart title, derive its ISO 2 letter Country Code, and look through the array list of (PHP) Timezones to garner latitude and longitude, time now, and GMT offset information necessary to improve the “where” and “when” aspects of our Google Chart Map Chart interfacing.
Yesterday’s Emoji Name Search Map Tutorial was a step in the direction of “where” functionality, but because PHP teams up with the supervisory HTML “Emoji World Flags” web application, to make all this happen, there is the opportunity to add interest by adding a “when” aspect to how it works.
As we’ve said many times now, should you have access to PHP, you also have access to its DateTimeZone class where Timezones can be linked to ISO 2 letter Country Codes, useful as an integration point as of recent times when we introduced ISO 2 letter Country Codes to today’s (supervisory) live run‘s world_flags.html HTML and Javascript code.
Yesterday’s posted data Emoji Name Search Posting Tutorial functionality opened the door to “where” web application (software) integration, because the wonderful Wikipedia has compiled Latitude,Longitude co-ordinate pairs for those countries, and that is our foot in the door to place an HTML a link under the Emoji flags, that points to our favourite “where” interfacing tool, the Google ChartsMap Chart.
Because the Map Chart and Emoji Flag web application share the same domain we can keep this functionality on this same Emoji Flag webpage in an …
HTML iframe element name=gcmiid=gcmi initially invisible … “populated by” …
HTML a element target=gcmihref=[URL to Map Chart for Country of Interest]onclick=aoc(); …
function aoc() {
document.getElementById('gmci').style.width='450px';
document.getElementById('gmci').style.height='450px';
document.getElementById('gmci').style.display='inline-block';
}
Yesterday’s Emoji Name Search Tailoring Tutorial was suitable for data sets of that smaller size able to be handled by the web server limit of URL length. But what if there are too many data items in your data set to be handled by PHP’s $_GET[] array URL ? and & delimited URLs? We, having PHP serverside code at our disposal, can turn to $_POST[] (HTML) method=POST form action=[here’sLookingAtYouKid] scenarios, to get around this issue. The unfortunate side effect of this is that the HTML mailto:a link (email client) method of sharing your Emoji web application relies on that $_GET[] approach, that is, unless you wrote a whole “bespoke” web application to help out, like we do today for our new Emoji “World Flags” web application with this live run, with this HTML and Javascript world_flags.html source code.
That new “supervisor” being a guinea pig idea into the $_POST[] thinking, we add some HTML form element input type=text additions to allow for, out of …
Emoji look class … and …
Wording next to Emoji … and …
URL of Wording’s link, be that substituted or appended
… mapped values, optionally, off a newly offered HTML form element input type=text for this mapped comma or blank separated word list.
Perhaps, now, you “long data set thinkers” want to try the live run and/or its PHP source code emoticon_keyboard_shortcuts.php changed in this way to extend its data set size capabilities.
Information Technology is full of “buzz words”, and am sure you wince at some to all of them yourselves. That’s a bit why am using “Tailoring” rather than …
sharing
personalization
… to give you a slumberrest from having to look under struck throughdeleted wording to look for hidden “buzz words”terminology that makes your harehair sit upstand watchingon Bugs Bunnyend.
We think, perhaps, that emojis can be important for young “would be” programmers to launch into. Personally wonder how many “would be” programmers give the game up far too soon just because they don’t have those graphics skills, well, with emojis, a lot of that hard work, in miniature, has been done for you by some pretty creative people, so why not enjoy the fruits (chortle, in context, chortle) of their labour and start developing your own web applications to use them. Daily, their use is increasing, as are the sharing of access methods.
In today’s extension to the functionality started with yesterday’s Emoji Name Search Primer Tutorial we separate the Emoji Terra aspects to how it works and allow the user to …
supply an Emoji Word List of interest
perhaps supply a heading and subheading to describe the “concept” of that list
supply either a …
URL prefix … or …
URL with the ~ (tilde) character where you want, substituted, your emoji name
… to be a navigation destination in that similar new window navigation we used to access Emoji Terra …
presenting all this in an HTML form action=[here’sLookingAtYouKid] method=GET …
that method=GET opening the door to be able to offer an email client engine method to “share”email somebody the link to a screen that looks like the one you’re seeing
Of course, we’d like you to find some of your own such Emoji Display Dynamically Created Web Applications yourself, but to encourage, we, in the web application, today, identified two ideas, namely …
Astrology via Cafe Astrology at https://cafeastrology.com/~dailyhoroscope.html via ~ (tilde) character substitution
… each of which (and any you make will also) feature a link to the HTML mailto:a link out through the email client and to your recipient who can click the email link to “share”compare notes.
Perhaps, now, you want to try the live run and/or its PHP source code emoticon_keyboard_shortcuts.php changed in this way to extend its functionality, involving a reveal favourite of ours, the use of HTML(5)’s details (and summary) element.

try to work out a generic “emoji lookerer upperer” arrangement
Guess you can tell we opted for the latter, huh?! We started the investigation of this by examining our three favourite emoji informational websites, namely …
… and were a bit surprised that we could not quite swing a generic method to glean the information, so don’t know whether our new “player” is “Ringo Starr” or not, but can tell you this, “its beat is much better than its bite” … chortle, chortle …
Emoji Terra performs similar functionality as Iemoji but has a permalink organization more friendly to an “emoji search via emoji title” query, and that suits our purposes today, so, thanks a lot. Without this query by “emoji title” possibility we’d have been forced to adopt more of those “hardcoded” arrays, which would have been alright, but this second approach opens the door to “sport” events in “The Rainbow Games” web application using emojis of the future (ie. they haven’t been invented yet).
amend that HTML source to supplant the “Sprint” default sport for this new nominated sport … trying not to fall over laughing at some of the new sports we present (inspired by a visit to Emoji Terra search)
write out that amended HTML code as the web page (the beauty of a serverside language like PHP)

in emojiland emoticonland arrangements there are five descriptors (as our suffixes if you will) … -dark-skin-tone, -medium-dark-skin-tone, -medium-skin-tone, -medium-light-skin-tone, -light-skin-tone
for that set of 2x1x5=10 URLs glean what “HTML dec” (HTML Entity) information you can glean via the file_get_contents call of the Emoji Terra URLs described above (eg. Emoji: Woman Biking: Dark Skin Tone) … built into a Javascript array string to “plug into” the previously read HTML partner source code, and amended to output as the web page the user sees
Again, in honour of “onions of the 4th dimension” approaches, we mainly, turn to the power of Javascript’s eval methodology to achieve this abstracted feeling to our web application. Today, with this, we go two thirds of the way along the “Mathematical Induction” approach …

prove for the second case

How does this use of Javascript eval manifest itself in this way?
there are two arrays that work with the “content” of our “Rainbow Games” sport(s) (well, at least, the first “sprint running” sport) called emoticons[] and choices[]
wherever we find references in the code to either of these two arrays we start to involve the global variable verbsuffix …
var verb='Sprint';
var verbs=['Sprint','Row'];
var anotherverb='run'; var verbsuffix='';
… in altered ways like …
function plus(ih,ihep) {
var outihep=ihep;
if (eval("emoticons" + verbsuffix + "[" + ih + "]").indexOf('<p>') != -1) {
outihep += ' (' + eval("emoticons" + verbsuffix + "[" + ih + "]").split('<p>')[1].split('<')[0] + ')';
}
return outihep;
}
… in that abstracted way … noting that sometimes you don’t need the “eval()” encasings …
and so, working through the code this way it just falls to the coder to define new members for all the arrays for all the new sports (ours is “rowing” today), some of those new arrays (like for rowing are emoticonsrowing[] and choicesrowing[]) to involve …
make sure the event logics work for multiple sport scenarios … but mostly they do by sticking to the principles above … especially for the …
new HTML select (dropdown) element allows the user to pick a sport
Remaining a work in progress, you can try out our live run link that has underlying HTML and Javascript and CSS emoji_walk_animation.htm, and which changed in this way regarding today’s genericization work. We hope it gives you food for thought.
We were on the “road to personalization” for the web application game we started with yesterday’s Rainbow Games Primer Tutorial when “an old chestnut” came up again. It’s happened before, the desire to “double transform” in CSS came about from our emoji …

So, still a work in progress that you can try out at our live run link that has underlying HTML and Javascript and CSS emoji_walk_animation.html, and which changed in this way regarding today’s work.
It’s been a while since we’ve written any conventional HTML and Javascript and CSS game. Today’s game uses the “emoticon” section of the Emoji character set, defaulting so far, to the “running woman” emoji featuring in Compound Emoji WordPress Usage Tutorial.
It’s the early days of our “Rainbow Games” web application, and we’re starting with the animation featuring horizontal hashtag navigation techniques for a running race start to our game. Where it finishes? Hard to say! Today, we’ve looked at “splits” and a finish line.
