Emoji Borders and Backgrounds via Emoji Menu Tutorial

On this macOS MacBook Air we’re used to …

… bringing up an Emoji Menu from which an emoji can be selected and placed wherever the cursor had been placed before that menu display. That could be …

• on an address bar where the cursor is placed
• in a Javascript prompt window that is focussed

… both scenarios (amongst many others, no doubt) of which we will be interested with our current Emoji Borders and Background web application project. Today’s work develops our PHP tool ahead of its supervisory web application, and so we are interested in the first scenario above, as far as testing it goes with our⚪inline_svg.php (latest) versus inline_svg.php---GETME (this)inline_svg.php---GETME (this) versus inline_svg.php--GETME (previous ... default)inline_svg.php---GETME (this) versus inline_svg.php-GETMEinline_svg.php---GETME (this) versus inline_svg.php_GETMEinline_svg.php (latest) versus inline_svg.php_GETME (oldest)changed underlying inline_svgphp PHP tool liverun web application.

The argument “text” is already catered for from yesterday but the nature of the data this $_GET[‘text’] might contain had not catered for …

• unicode data (via Emoji Menus) … but rather had catered for …
• Javascript call of String.fromCodePoint([comma separated list of HTML Decimal Entity(s)]);

… only, as of yesterday’s Emoji Borders and Backgrounds Image Text PHP SVG Tutorial. As you would probably concur, yesterday’s setup was quite user unfriendly, as so many of us now are used to those Emoji Menus being used to fill in your emoji data requirements.

The main gist of the PHP code changes goes …

<?php


$innards='';

$preinnards='';



function ingp($m) { // thanks to https://pretagteam.com/question/how-do-i-convert-unicode-special-characters-to-html-entities

global $innards, $preinnards;

if ($innards != '') {

$entity = preg_replace_callback('/[\x{80}-\x{10FFFF}]/u', function ($m) {

$char = current($m);

$utf = iconv('UTF-8', 'UCS-4', $char);

return sprintf("&#x%s;", ltrim(strtoupper(bin2hex($utf)), "0"));

}, $innards);

$preinnards=htmlentities($entity);

$innards='';

}

}



// And then later we change ...

if (isset($_GET['insvg'])) {

$innards=str_replace('+','',urldecode($_GET['insvg']));

if (trim(str_replace(',','',str_replace('0','',str_replace('1','',str_replace('2','',str_replace('3','',str_replace('4','',str_replace('5','',str_replace('6','',str_replace('7','',str_replace('8','',str_replace('9','',$innards)))))))))))) != '') {

ingp($innards);

}

if ($preinnards == '') {

$preinnards='&#' . str_replace(',',';&#',$innards) . ';';

}

// rest of if block code uses $preinnards as SVG text innerHTML ... but UTF-16 Surrogate pair scenarios can fail

}

… the functionalities that would be “cool” at the HTML/Javascript/CSS parent side, and then work out how to implement similar functionality, as possible, in SVG, and if possible, we should be able to pass arguments over to the “PHP tool” to eventually code it to be standalone to help other “parenting arrangements”.

And so, today, we “get functional” the combination of parental control through to PHP SVG child display …

But, so far, how would we assess the approach, here? Well, what we had to do today reminded us a lot of what we do here, often, at this blog, when we talk about “overlay” webpage design approaches. CSS position:absolute and opacity and Javascript [element].getBoundingClientRect() all made guest appearances!
