I'm trying to pass a string with a AJAX Post to a PHP script and then find the string in a mySQL database, any idea what I'm doing wrong?

Heres the top of the AJAX:

Code:
$.ajax({ 
				url: "pick.php", 
				type: "post", 
				data: {video_id: vid_id },
(vid_id) is the string var

And heres the PHP:

Code:
if (isset($_POST['video_id'])) {
		$id = ($_POST['video_id']);
		
		$text_result = mysql_query("SELECT * FROM `wmtwDB` WHERE `url` LIKE (" . $id . ") LIMIT 1");
Any ideas where I'm going wrong?
