Question

So, heres a super simple jQuery / AJAX comment system step one. Step two is the PHP to insert the data into the DB. I need the $_GET[‘variable’] for the page / a $_SERVER[‘variable’] to store into the DB. How can I get these in the jquery. I can’t just say $spot = $_GET['spot'] or $url = $_SERVER['FILE_SCRIPTNAME'] in the PHP. It won’t pick it up. I has to be sent through the jQuery / AJAX. How can I do this?

$(document).ready(function() {
        $('#submit_comment').click(function() {
            var comment = $('#place_comment').val();
            // Somewhere here set the $_GET['variable'];
            $.ajax({
                type: 'POST',
                url: 'http://localhost/app/comment/comment.func.php',
                data: 'comment='+comment,
                success: function(data) {
                    $('#replies').html(data);
                    }
                });
            });
        });

If I understand what you are trying to do correctly, you can try something like this to use server-side PHP variables in your client-side javascript.

var comment = $('#place_comment').val();
var myVariable = '<?php echo $_GET['variable'] ?>';
