通过$ _GET将URL变量传递给Javascript

Question

I have a PHP page with the following URL:

http://xyz.com/dev/gallery.php?k=1&s=35

The following Javascript file is included on the PHP page:

<script type="text/javascript" src="js/some-js-file.php"></script>

The some-js-file.php needs to be filled dynamically using PHP:

jQuery(function($){$.supersized({

<?php 
$sql = "SELECT * FROM tbl WHERE id=".$_GET['s']." ORDER BY pos ASC"; 
$result = mysql_query($sql); 
    while($rs = mysql_fetch_row($result)){
    ...do some output here...
    }
?>

});
});

For some reason, $_GET['s'] is empty. Any ideas why? Thanks in advance for any help!

Answer 1

Pass the parameter to the JavaScript file as well:

<script src="js/some-js-file.php?s=<?php print $_GET['s']; ?>"></script>

NB: Please pay attention to Quentin's comments and make sure that you use the approach securely.
