How to use symfonyCollectionJs without symfony
To use this package without Symfony, you only need to have the data-prototype attribute properly set. We provide you with this example in php, but you can do this in every language, and most likely with most frameworks:
<?php
// __name__ being the prototype name, it is here the placeholder for the index in ids and names
function getCollectionElementHtml(): string
{
$html = <<<EOD
<div id="collection-root">
<div class="collection-elem">
<div>
<button class="collection-elem-add">+</button>
<button class="collection-elem-remove">-</button>
<button class="collection-elem-up">up</button>
<button class="collection-elem-down">down</button>
</div>
<h2>This is a collection element</h2>
<input type="text" id="form_collection___name___myinput" name="form[collection][__name__][myinput]">
<input type="text" id="form_collection___name___myotherinput" name="form[collection][__name__][myotherinput]">
</div>
</div>
<button id="collection-add-btn">Add element</button>
EOD;
return $html;
}
function encodeHtmlForPrototype(string $html): string
{
return htmlspecialchars($html);
}
?>
