I'm comfortable with PHP but I'm not very familiar with jquery, and I'm not sure why it's not working here. I have checked the file paths and they're working correctly.

I'm trying to get this post data to work with jquery/ajax in controlpanel.php.

Controlpanel.php

Code:
<?php
include('class/db.php');
require_once("config/db.php");

require_once("class/Login.php");
$login = new Login();


if ($login->isUserLoggedIn() == true) {
    include("views/logged_in.php");
} else {
    include("views/not_logged_in.php");
}

$user1 = $_SESSION['user_name'];

$db = new Database();
$db->connect();
$user = $db->escape($user1);
$db->select('templates', 'template_description, template_name', NULL, 'userID="'.$user.'"');
$res = $db->getResult();

?>

<h2><u>Delete</u></h2>

<?php print "<table border=\"1\">
