How can I store a bootstrap modal inside a variable? - php

Question

I want to write a php function to generate a Bootstrap modal so I can simply call it to create more modals. Thus reducing code repetition. My first approach was to store all the HTML within a Variable and then return it as shown in the function below.
function modal(){
$build = ' <button type=button class="btn btn-primary" data-toggle="modal" data-target="modal-xl">
Test Modal
</button>';
$build .= ' <div class="modal fade" id="modal-xl">
<div class="modal-dialog modal-xl">
<div class="modal-content">
<div class="modal-header">
<h4 class="modal-title">Extra Large Modal</h4>
<button type="button" class="close" data-dismiss="modal" aria-label="Close">
<span aria-hidden="true">×</span>
</button>
</div>
<div class="modal-body">
<p>One fine body…</p>
</div>
<div class="modal-footer justify-content-between">
<button type="button" class="btn btn-default" data-dismiss="modal">Close</button>
<button type="button" class="btn btn-primary">Save changes</button>
</div>
</div>
</div>
</div>';
return $build;
}
And then to generate it I would simply do
<?=modal()?>
My problem with this approach is that although the code is inserted inside my page, I can't seem to be able to open the modal in question.
Anyone has some though? or alternative way of doing so?
I was hoping to create a Builder class for various components like this one.

Alright for modals, I manage to get it working by using a javascript trigger instead.
function modal(){
$build = ' <button type=button class="btn btn-primary" id="btn-xl">
Test Modal
</button>';
$build .= ' <div class="modal fade" id="modal-xl">
<div class="modal-dialog modal-xl">
<div class="modal-content">
<div class="modal-header">
<h4 class="modal-title">Extra Large Modal</h4>
<button type="button" class="close" data-dismiss="modal" aria-label="Close">
<span aria-hidden="true">×</span>
</button>
</div>
<div class="modal-body">
<p>One fine body…</p>
</div>
<div class="modal-footer justify-content-between">
<button type="button" class="btn btn-default" data-dismiss="modal">Close</button>
<button type="button" class="btn btn-primary">Save changes</button>
</div>
</div>
</div>
</div>';
$build .= ' <script>
$(document).ready(function(){
$("#btn-xl").click(function(){
$("#modal-xl").modal();
});
});
</script>
';
return $build;
}
Hopefully I won't have to trick bootstrap like this with all other components.
PS. Make sure to load JQuery and Bootstrap Javascript before echoing the function.
