how can i pass variable to php after open modal - php

Question

Hi I want to open modal after I click on button. But I want to display different content on the basis on which button I click.
So in html I have:
<h1>article1</h1>
<div class="btnComment">
<button class="btn btn-primary" data-toggle="modal" data-target=".bs-example-modal-lg">Comment button 1</button>
</div>
<h1>article2</h1>
<div class="btnComment">
<button class="btn btn-primary" data-toggle="modal" data-target=".bs-example-modal-lg">Comment button 2</button>
</div>
<div class="modal fade bs-example-modal-lg" tabindex="-1" role="dialog" aria-hidden="true">
<div class="modal-dialog modal-lg">
<div class="modal-content">
<div class="modal-header">
<button type="button" class="close" data-dismiss="modal" aria-label="Close"><span aria-hidden="true">×</span></button>
<h4 class="modal-title" id="gridSystemModalLabel">Comments</h4>
</div>
<div class="modal-body">
<?php
mysql_query("set names 'utf8'");
$selectConf = mysql_query("SELECT * FROM e_comments WHERE article='".$article."'");
$count = 0;
if($selectConf){
while ($row = mysql_fetch_array($selectConf)) {
$text = $row['text'];
echo $text;
}
}
?>
</div>
</div>
</div>
</div>
So how can I know in modal which button was clicked? And how I can pass some variable throw it? I want to show comments of article. So I need to pass id of article and select all comments where is id of article same.

There's a direct example on the bootstrap page at http://getbootstrap.com/javascript/#modals-related-target. Here is the equivalent code for your dialog
<script>
$(document).ready(function () {
$('.bs-example-modal-lg').on('show.bs.modal', function (event) {
var button = $(event.relatedTarget)
alert(button.html())
})
})
</script>
edit : you'd have to change the alert() part to whatever if else logic you want.
