Emoji Objects Game Tutorial

Even though we have been using “Drag and Drop” methodologies a lot lately, it was way back in late September 2023, with Inhouse WordPress Blog Posting Game Tutorial, when we last needed to change that client HTML and Javascript Drag and Drop clientside basis, that all the PHP parents look to. But today we need to change it, because we have a new …

  • drag and drop methodology based …
  • Emoji Objects Game … involving linking an emoji to a single noun word (representing a “room” type) … or vice versa … that we think could benefit via …
  • allowing a user to pick a non-English language to translate the whole web application into

… as they try our “proof of concept” emoji_object_game.php Emoji Object Game tapping into that changed experimental_drag_and_drop.htm Drag and Drop basis.

So far only this Emoji Objects Game offers these new Drag and Drop Language interfacing smarts, because we found the Internationalization combination of “emojis” and “single noun word answers” as an irresistible combination to try this concept out with, and after bedding down this idea, we’re pretty sure we’ll improve on that “single use situation” over time!

As far as …

  • emoji data goes we’d like to thank Emojipedia for the emoji categorization help … and …
  • as far as language translations go we’d like to thank Google Translate

… profusely!

Inhouse WordPress Blog Posting Game Tutorial

The WordPress 404.php Tutorial Picture image creation work in yesterday’s Interactively Change WordPress Blog Background Image on Scroll Tutorial set us to thinking of a Drag and Drop game (akin to those in the recent discussions) we could set up to …

  • show the user, in the “Drag” section a WordPress Blog Posting Title (and date) … which the user should drag to the appropriate …
  • table cell, nine of which exist in the “Drop Zone”, and are numbered and backgrounded by a random WordPress Tutorial Picture image

… in alignment with the adage …

Every picture is worth a thousand words.

As well, today, both in terms of …

  • providing hints … and/or …
  • providing information

… those table cells are associated with …

  • double click event (“ondblclick”) logic that shows the “Cut to the Chase” underlying “action item” associated with the WordPress Blog Posting involved … and, just quietly …
  • right click event (“oncontextmenu”) logic that shows the associated WordPress Blog Posting involved itself

… in our first draft “proof of concept” PHP based Inhouse WordPress Blog Posting Game (helped out by a tweaked experimental_drag_and_drop.htm Drag and Drop basis) we hope you get to try below (when it transforms into the Inhouse Blog Game after the default incarnation) …

… worked by our WordPress 404.php now containg the PHP code snippet …

<?php

if (strpos(('' . str_replace(');%20}','',$_SERVER['QUERY_STRING']) . '~'), '437195~') !== false) { // Drag and drop quiz
//file_put_contents($_SERVER['DOCUMENT_ROOT'] . DIRECTORY_SEPARATOR . 'p.p','here');

}
}
file_put_contents($ptfileis, $prevcontis . "\n" . $ptitle . '?' . str_replace(');%20}','',$_SERVER['QUERY_STRING']));

Interactively Change WordPress Blog Background Image on Scroll Tutorial

With yesterday’s Interactively Change Background Image on Scroll User Settings Tutorial‘s offering were you “an intrepid”, typing …

//www.rjmprogramming.com.au/ITblog/600/400/

… into that newly minted Javascript prompt window designed for user interaction purposes? This populates the background images in our new Image Scrolling with Fixed Text web application with a random selection from the WordPress Blog you are reading. Because we have some control here, we researched whether our WordPress 404.php logic could be tweaked to help out more in this scenario. The way the PHP works here, detecting this situation, at the end of its workings, is to use an image header (exemplified by the GIF one below) …

<?php

header('Content-Type: image/gif');
echo file_get_contents($path);
exit;

?>

… where $path would point at a GIF image file residing on the RJM Programming domain web server. This design restricts us from any echo functionality before this, so what can we achieve? Anyone? Anyone? Yes, Rasmus, we can write to other web server files that could be like middle-people between the server (supplier of image data) and client (the webpage that called the server). After the server work …

<?php

if (strpos(('' . str_replace(');%20}','',$_SERVER['QUERY_STRING']) . '~'), '591734~') !== false) {
//file_put_contents($_SERVER['DOCUMENT_ROOT'] . DIRECTORY_SEPARATOR . 'p.p','here');
$prevcontis='';
$ptfileis=$_SERVER['DOCUMENT_ROOT'] . DIRECTORY_SEPARATOR . 'ptitledata.html';
if (file_exists($ptfileis)) { // thanks to https://stackoverflow.com/questions/67707029/how-do-i-get-how-long-the-file-was-created-in-seconds-in-php
$modifdate = filemtime($ptfileis);
$secondsago = time() - $modifdate;
if ($secondsago > 5) {
unlink($ptfileis);
} else {
$prevcontis=file_get_contents($ptfileis);
}
}
file_put_contents($ptfileis, $prevcontis . "\n" . $ptitle . '?' . str_replace(');%20}','',$_SERVER['QUERY_STRING']));
//file_put_contents($ptfileis . "huh", $prevcontis . "\n" . $ptitle . '?' . str_replace(');%20}','',$_SERVER['QUERY_STRING']));
//} else {
// file_put_contents($_SERVER['DOCUMENT_ROOT'] . DIRECTORY_SEPARATOR . 'p.q',('' . str_replace(');%20}','',$_SERVER['QUERY_STRING']) . '~'));
}

… back at that client (which called the server with that appended “591734” placed onto the URL to indicate the intention to want to examine this return data), we have Ajax based Javascript logic …

Interactively Change Background Image on Scroll User Settings Tutorial

If you are a regular reader, you’ll know with the web applications presented here, we usually try to allow the user to control …

  • how they function … and/or sometimes …
  • how they look

… in the ephemeral “this session” sense, and sometimes follow that up, depending, with recallable settings often calling on window.localStorage or HTTP Cookies, associated with the web browser being used.

Regarding that ephemeral “this session” sense above, building on the work of yesterday’s Interactively Change Background Image on Scroll Tutorial, we now allow the user control over defining any/all …

  • Background Image source URL
  • Refresh delay (in seconds)
  • Text Wording
  • Text Background Image source URL

… and regarding the use of that last one, we’ve decided, somewhat, to take over with the CSS regarding the Text Wording showing through amongst so many “image interests” with various opacities …


var mode='dw';

function preask() {
if (backimg.trim() != '') {
if (backimg.toLowerCase().replace(/\ /g,'') == 'lorempicsum') {
backimg='//picsum.photos/600/400' + suffix + '?random=' + Math.floor(Math.random() * 198765643);
if (mode == 'dw') {
mode='';
document.write('<style> .bg-text { background: linear-gradient(rgba(255,255,255,0.8),rgba(255,255,255,0.8)),URL("' + backimg + '"); background-size: contain; background-repeat: repeat; text-shadow:-2px 2px 2px #ff2d95; opacity: 0.9; } </style>');
} else {
document.getElementById('dstyle').innerHTML+='<style> .bg-text { background: linear-gradient(rgba(255,255,255,0.8),rgba(255,255,255,0.8)),URL("' + backimg + '"); background-size: contain; background-repeat: repeat; text-shadow:-2px 2px 2px #ff2d95; opacity: 0.9; } </style>';
}
backimg='lorempicsum';
} else {
if (mode == 'dw') {
mode='';
document.write('<style> .bg-text { background: linear-gradient(rgba(255,255,255,0.8),rgba(255,255,255,0.8)),URL("' + backimg + '"); background-size: contain; background-repeat: repeat; text-shadow:-2px 2px 2px #ff2d95; opacity: 0.9; } </style>');
} else {
document.getElementById('dstyle').innerHTML+='<style> .bg-text { background: linear-gradient(rgba(255,255,255,0.8),rgba(255,255,255,0.8)),URL("' + backimg + '"); background-size: contain; background-repeat: repeat; text-shadow:-2px 2px 2px #ff2d95; opacity: 0.9; } </style>';
}
}
}
}

Which beggars the observation …

Isn’t the CSS text-shadow property just great?!

We use it more and more often to help out foreground text presented with a lot of “overlay imagery” going on behind it.

Here is the Javascript prompt window “blurb” presented to the user should they want to delve into this woooooorrrrrlllllldddd just by clicking or touching in the non-text part of the webpage …

var ansis=prompt(‘Optionally enter in background source URL prefix [‘ + prefix + midbit + suffix + ‘] ( or type Lorem Picsum or for blog posting images you could try //www.rjmprogramming.com.au/ITblog/’ + sixhundred + ‘/’ + fourhundred + ‘/ ), hashtag delimited from an optional imagery refresh rate in seconds [‘ + ten + ‘], hashtag delimited from an optional Text element background image (or type Lorem Picsum), hashtag delimited from optional Text wording [‘ + tcont + ‘] we will assume involves a space.‘, ”);

Regarding today’s “Interactively Change Background Image on Scroll” topic, we’d like to thank, profusely, two sources …

Queue … Lulu (no, not the dog, this time)!

Yes, we’ve just added “Interactively”, we hear you say (just maybe, perhaps, a tad sarcastically, shall we say … huh?!!!!). But, it’s the …

… that is all a bit new, at least to us, today, continuing on the recent wonder regarding contenteditable=true, mentioned in the recent Animated GIF SVG Quiz Automation Interaction Tutorial …

And did you know, at least for non-mobile platforms, you can set the focus (on non-mobile platforms only, as there are the “keyboard getting in the way” issues we’re thankful for with mobile platforms which preclude any thoughts of a programmed [element].focus() operation) to one of these “contenteditable=true style elements”? We’d never been sure, only focussing to HTML input textboxes and textareas up to now, we believe.

… whereby non-mobile focus to a contenteditable=true HTML div type (innerHTML style) element is possible, adding to the original W3School’s content ideas swirling around …

  • CSS position: fixed; … for foreground text, in relation to …
  • scrolling … with …
  • background imagery
