MAMP Timekeeping Web Application PHP Notifications Tutorial
Today we’re revisiting the macOS (or Mac OS X) or Windows timekeeping web application of 2016’s Mac OS MAMP Timekeeping Web Application PHP Calendar Aesthetics Tutorial. Why? Well, given our recent work with Notifications API based web applications you can read about at Notification API Hidden Popup Tutorial, the timekeeping one is a great candidate for functionality improvement here, it being a web application that …
- can work behind the scenes …
- not necessarily frontmost … but benefitting from any …
- notification reminders separate from web activities and webpage focus issues can help tell the user when they might want to turn back attention to the timekeeping screenshot recording
This needs PHP to work and it needs real access via PHP exec function to underlying operating system commands. When this happens, we still try to offer a public RJM Programming interface but this interface is far less useful if you have not downloaded to your local Apache/PHP/MySql local web server (such as a MAMP one) as per …
- the changed quarter_hour_timer.php (we ask you to download to MAMP‘s $_SERVER[‘DOCUMENT_ROOT’] “HTMLCSS” subfolder) Timekeeping Web Application suited to macOS (or Mac OS X) “screencapture” command line usage
- the unchanged (from tutorial below, supervisory HTML and Javascript) quarter_hour_timer.html (we ask you to download to MAMP‘s $_SERVER[‘DOCUMENT_ROOT’] “HTMLCSS” subfolder) Timekeeping Web Application
- the “how we got there” PHP notifications_ideas.php (we ask you to download to MAMP‘s $_SERVER[‘DOCUMENT_ROOT’] subfolder) Notification API functionality PHP web application
… in what we like to call an “Intranet feeling” scenario.
Up at the public RJM Programming domain, as far as the Notification API functionality supervisor webpage goes, the changed HTML and Javascript notifications_ideas.html Notification API functionality HTML and Javascript web application is worth trying.

.adaNOte { border: 3px solid pink; border-radius: 7px; }
a.adate { border:2px solid transparent; background-color:lightgreen; border-radius:50px; }
</style>
- settle for mobile platforms never being able to screenshot, on this round of looking, and redirecting to the “Monthly Chronicler” web application (of (the unchanged) monthly_chronicler.html we ask you to download to MAMP‘s $_SERVER[‘DOCUMENT_ROOT’] “HTMLCSS” subfolder) …

… which you may glean has a Windows “fallback” position (with that “copy” codeline). Why? Well, we found a .Net framework “exe creation via bat” using ScreenCapture.bat (thanks to this useful link) created black screen shots. Probably a privilege thing or PHP exec thing, but we’ve opted for the workaround, which is just “Windows talk” …
- write Windows batch scapcontinuous.bat as a continuous fifteen minute user of the .Net Framework (ScreenCapture.exe) derived from above
- set up a task via “Task Schedular” (please ignore the warts ‘n all “garden path” schtask ideas in the video below) that has an action “C:\MAMP\htdocs\scapcontinuous.bat” and starts when the Windows user logs in and takes (successful) screen shots at 14 and 29 and 44 and 59 minutes (in the hour) times

Mac OS MAMP Timekeeping Web Application PHP Calendar iCal Integration Tutorial
Yesterday’s Mac OS MAMP Timekeeping Web Application PHP Calendar Contenteditable Tutorial‘s “Calendar Past” improvements don’t have to be the end of the story regarding “calendar timings”. There is an Apple iCal standard interfacing format that can drive calendar integrations with many well known online Calendar applications.
You may recall us talking about this with Calendar Location Services Integration Tutorial and we tweak the changed ics_attachment.php (which we’d ask you to download to MAMP‘s $_SERVER[‘DOCUMENT_ROOT’] “PHP” subfolder) and its standalone ical creator to better integrate with the changed quarter_hour_timer.html (we ask you to download to MAMP‘s $_SERVER[‘DOCUMENT_ROOT’] “HTMLCSS” subfolder) Timekeeping Web Application suited to macOS (or Mac OS X) “screencapture” command line usage.
This bit of functionality works (interfacing) both with MAMP and with the public RJM Programming domain incarnation of the Timekeeping web application, so that could be interesting. It can interface via …
… modes of use. In action, should you create an iCal file this way, the web application will download the resultant .ics file into your Downloads folder and to interface into your default online Calendar application double click that Downloads folder file to complete the Calendar integration …

Mac OS MAMP Timekeeping Web Application PHP Calendar Contenteditable Tutorial
We’ve spoken quite a bit in the past about the joys of involving the “contenteditable=true” attribute for HTML elements that have an “innerHTML” (ie. they have a formalized end tag arrangement eg. div, span, p, td, th etcetera) and with today’s work which extends that started with yesterday’s Mac OS MAMP Timekeeping Web Application PHP Calendar Past Tutorial it is the turn of a set of “p” elements it helps out today.
The scenario is that yesterday’s work did not allow for “orphaned screenshots” of the past be allowed to be brought back into play to “annotate them” and in so doing “give them a home”. This led us to …
- allow for a new “Infill Earlier Days All Screenshots” button augment yesterday‘s “Infill Earlier Days Just Annotated Screenshots” button …
- the pressing of that new “Infill Earlier Days All Screenshots” button causes all screenshot 15 minute entries relevant to the current year be displayed in the calendar … but then it occurred to us users might want to “annotate them” … but how? …
- in the PHP we introduced code …
<?php
if (isset($_GET['yourta'])) {
$dru="http://" . $_SERVER['SERVER_NAME'] . "" . str_replace("~","",str_replace(":443~","",str_replace(":80~","",(":" . $_SERVER['SERVER_PORT'] . "~")))) . "/";
$cet="";
if (strlen($_GET['yourta']) != 0) { $cet=" contenteditable=true onblur=repostit(this); onfocus=wopen(event,false); "; }
// blah blah blah
$ccpre="
// blah blah blah
}
?>
… to, when an “orphaned” screen shot image is happened upon, allows … - contenteditable=true “does its stuff” turning might might have been a pretty unintelligent HTML element into a “textarea” type collector of user input, and then that onblur event logic’s “midair feeling” Ajax/FormData “recursive feeling” methodology …
function repostit(ih) {
var ihis=(ih.innerText || ih.contentWindow || ih.contentDocument);
var pathpart=ih.id;
if (ihis != '') {
var xzhr = new XMLHttpRequest();
var xform=new FormData();
xform.append('myta',ihis);

Mac OS MAMP Timekeeping Web Application PHP Calendar Tutorial
Okay then, yesterday’s Mac OS MAMP Timekeeping Web Application PHP Image Metadata Tutorial “image metadata smarts” puts us in a position to get onto the “bells and whistles” side of our Timekeeping (macOS and Mac OS X only at this stage) web application. We channel the calendar display talents of Monthly Chronicler LocalStorage Tutorial in thought and act (its web application is opened in an iframe … hence our need to ask you to download monthly_chronicler.html to MAMP‘s $_SERVER[‘DOCUMENT_ROOT’] “HTMLCSS” subfolder) to offer a new (“reveal”) piece of details/summary hosted “Yearly Report Calendar” functionality.

Mac OS MAMP Timekeeping Web Application PHP Image Metadata Tutorial
In our opinion, what would make the day before yesterday’s Mac OS MAMP Timekeeping Web Application PHP Intranet Tutorial “Timekeeping Web Application” cooler would be to add to the intelligence of the screen capture images, ahead of other data related improvements to come.
We’ve spoken in the past about Exif in that respect but PHP has Iptc image metadata functions we can call on …
- iptcembed to embed new metadata into an existant image from those associated “caption” textarea elements we offer
- iptcparse to extract old metadata from an existant image into those associated “caption” textarea elements we offer
This metadata can be like a database source we use moving forward on this project, meaning the one image data entity can suffice for both visual and textual usage purposes.
And so our changed quarter_hour_timer.html Timekeeping Web Application suited to macOS (or Mac OS X) “screencapture” command line usage, is helped out by a much more usefully changed quarter_hour_timer.php PHP …

Mac OS X MAMP Timekeeping Web Application Email Tutorial
The practicalities of yesterday’s (Mac OS X MAMP Timekeeping Web Application Primer Tutorial) timekeeping Mac OS X Web Application, left as they are, would leave you with a somewhat useful web application whose use is only for the here and now, but what if you want it to be more accountable? Well, that is when we, here, at RJM Programming, like to use that tried and trusted email form of communication.
Today’s email methods spurn the use of server-side intervention, at least for now. So what is available to us as tools, if we don’t include Ajax nor jQuery in that list? Well, we have, to our minds …
- mailto links (get us to the email client) +
- the body section of that email can have a clipboard image pasted into it, for which we can utilize HTML5 canvas element’s toDataURL() method, teamed up with a window.open popup window of the toDataURL image data, which can be selected and copied, optionally, by the user themselves, should they wish this to make their email more self explanatory
We last discussed this thinking with Canvas Annotation Email Attachment Clipboard Tutorial.
We rely on the crontab functionality, being as there is no server-side help, to create the image file, whose contents eventually go to make up the contents that can be selected and copied and pasted by the user into the body section of the email (and sent off to whosoever they feel like sending it too, as you have the full power of the email client available to you with the interaction you have with an actual email client program).
Here is the HTML and Javascript quarter_hour_timer.html which changed to cater for today’s email functionality in this way, and, as per the Stop Press from yesterday, we’ll also have a live run link here today.
Previous relevant Mac OS X MAMP Timekeeping Web Application Primer Tutorial is shown below.
Mac OS X MAMP Timekeeping Web Application Primer Tutorial
Sometimes when you program, especially for administrative type functionality, there are useful programs to write, that are able to become web applications, but in a limited set of platforms. So it is today with our timekeeping web application that relies on …
- Mac OS X operating system +
- Existance of [/usr/sbin/]screencapture +
- crontab active and editable via crontab -e +
- One of …
- MAMP installed to, in our case, /Applications/MAMP/htdocs/ (as is mentioned in the relevant crontab background task that snapshots the user’s screen every quarter hour) that maps to the MAMP web application URL http://localhost:8888/ … or …
- crontab directory mention that corresponds to a URL call of our web application like for our Google Chrome example (where the directory below, used, could be a place of your choosing (that matches what is in your crontab task entry)) …
file:///Applications/MAMP/htdocs/quarter_hour_timer.html?localplace=
… or just, via the web browser’s File -> Open File menu …
file:///Applications/MAMP/htdocs/quarter_hour_timer.html
… pretty restrictive, huh? … but pretty useful for our quarter hour timekeeping purposes today.
We want to have a web application that is running at the user’s discretion, and when first fired up, looks for outputs from crontab tasks above …
0,15,30,45 * * * * /usr/sbin/screencapture -Cd -tjpg /Applications/MAMP/htdocs/screen-`date +"\%Y\%m\%d-\%H\%M"`.jpg
… for the current day in question and if existant show …
- a date and time stamp +
- the snapshot of what you were doing at the quarter hour, that is clickable to make bigger for more in depth viewing +
- an HTML textarea element in which you can optionally type in more specifics about that quarter hour
So, as much as we like to think of Mac OS X Terminal application’s BSD (a unix derivative) operating system, as being a lot like Linux, there are some commands and usage that …
- adds Mac OS X specific command line functionality to a Linux or unix base set of functionality, like for today’s screencapture command … and we’ve included another such example, below, with the command say featuring in Mac OS X Text to English Speech Primer Tutorial as shown below
- changes switches on Linux or unix commands
- won’t have some Linux or unix commands that other platforms do
In the great tradition of behoving … we behove … we behove thee quarter_hour_timer.html if you like, my liege. On this occasion you’ll have gleaned that there is no live run link, because the RJM Programming web server is not Mac OS X … so command line screencapture has no meaning for a CentOS web server’s operating system command line. You’ll see in the code that rather than use “Client Pre-emptive Iframe” concepts to check for existence of crontab screen capture images, we, instead use the onerror event for HTML img elements to check for non-existance.
Stop Press
Just noticed that, perhaps, after all, a live run from the RJM Programming website can make sense if you have a Mac OS X laptop, for instance, that is running that suggested crontab entry as explained in tutorial above. That type of live run managed to latch on to our local crontab screencaptures on my MacBook Pro.
Previous relevant Mac OS X Text to English Speech Primer Tutorial is shown below.
Mac OS X Text to English Speech Primer Tutorial
We’ve got a few new ideas today …
- Text to English Speech via Mac OS X’s command line say command used by PHP via exec to make say.php (which is useful as a download to a Mac OS X laptop using MAMP) which, today, does not have a live run because the web server of domain rjmprogramming.com.au is a CentOS Linux server … Linux equivalent of Mac OS X’s say? … read here
- Trying to present this brought up the usual movie production problem with iMovie overlaying the audio on top of the video (though you may want to try, and you could start reading with this link) versus QuickTime Player talent to catch both audio and video tracks (and that we ended up using), but not of the “screen goings on”, alas versus MPlayer OSX Extended which can play separately but not two tracks on top and doesn’t do any reconstituting … so …
- Improved on our inhouse Video/Audio synchronizing efforts by allowing audio_video.html supervisor (changed in this way) be able to be called to press one of its preconceived synchronization buttons onload which we do with (the newly added) Macbeth Act 1 Scene 1 … in a small celebration of the Bard … who, am thinking (in that Falstaff way), would have got a huge chuckle out of “anonymous” instead of “anon” during the Three Witches scene … we had to do something to say Happy Birthday
Along the way we tried filming the MacBook Pro with the iPad to a YouTube …
… but weren’t happy with the audio quality, alas (too/two).
