Passing variables to a bootstrap modal form - php

Question

I have a table that shows film reviews stored in a mysql database. Each of these reviews can be edited with a form that resides within a bootstrap modal. The problem I have is I can't understand how to give each form within the modal a unique ID. At the moment the modal only ever echoes varibales from the first row of reviews in the database. Many thanks.
The Jquery
<script type="text/javascript">
//Edit Review
$(document).ready(function(){
$(".editReview").click(function (e) {
$('#myModal').modal({
e.preventDefault();
var username = $(this).data("username");
var film_id = $(this).data('filmid');
var id = $(this).data('id');
var review = $(this).data('review');
$.post('ajax_editReview.php', {username: username, film_id: film_id, id: id, review: review},
function(data){
$('#myModal').modal('hide');
$("#message").html(data);
$("#review").val('');
$("#message").fadeIn(500);
$("#message").fadeOut(2500);
});
return false;
});
});
</script>
The Form
<div class="container">
<?php
$sql = "SELECT * FROM user_reviews WHERE username='$username' ORDER BY DATE desc";
$result = $db_conx->query($sql);
while($row = $result->fetch_assoc()) {
$id = $row['id'];
$film_id = $row['film_id'];
$review = $row['review'];
$movie = $tmdb->getMovie ($film_id);
echo '
<div class="row">
<div class="col-md-1">
<img id="image1" src="'. $tmdb->getImageURL('w150') . $movie->getPoster() .'" width="80" />
</div>
<div class="col-md-4">
<h3>
' . $movie->getTitle() .'
</h3>';
<p>
'.$review. '
</p>
<!-- Trigger the modal with a button -->
<button type="button" class="btn btn-success btn-xs pull-right" data-toggle="modal" data-id="'.$id.'" data-username="'. $username.'" data-filmid="'.$film_id .'" data-target="#myModal">edit review</button>
<!-- Modal -->

<div class="modal-body">

}

You need to have the modal only once on your page and it seems like you a creating a new one for every review, you don't need to do that, just output it once.
You then need to use the event show.bs.modal like so.
$('#myModal').on('show.bs.modal', function (event) {
var button = $(event.relatedTarget) // Button that triggered the modal
var username = button.data("username");
var film_id = button.data('filmid');
var id = button.data('id');
var review = button.data('review');
....
});
