[cyber_alchemist]

I found this small CMS script over the internet , all tough this script few errors, i managed to clear a few, but I still can't find the problem why it isn't posting any data into the database.

<?php
require_once 'db.inc.php';
require_once 'cms_http_functions.inc.php';

$db = mysql_connect(MYSQL_HOST, MYSQL_USER, MYSQL_PASSWORD) or
    die ('Unable to connect. Check your connection parameters.');

mysql_select_db(MYSQL_DB, $db) or die(mysql_error($db));

if (isset($_REQUEST['action'])) {

    switch ($_REQUEST['action']) {
    case 'Submit New Article':
        $title = (isset($_POST['title'])) ? $_POST['title'] : '';
        $article_text = (isset($_POST['article_text'])) ? $_POST['article_text']
            : '';
        if (isset($_SESSION['user_id']) && !empty($title) &&
            !empty($article_text)) {
            $sql = 'INSERT INTO cms_articles
                    (user_id, submit_date, title, article_text)
                VALUES
                    (' . $_SESSION['user_id'] . ', 
                    "' . date('Y-m-d H:i:s') . '",
                    "' . mysql_real_escape_string($title, $db) . '",
                    "' . mysql_real_escape_string($article_text, $db) . '")';
            mysql_query($sql, $db) or die(mysql_error($db));
        }
        redirect('cms_index.php');
        break;

    default:

    }
} else {
    redirect('cms_index.php');
}
?>

It is the article transact file...

 

and below is the composing script :

<?php
require 'db.inc.php';
include 'cms_header.inc.php';

$db = mysql_connect(MYSQL_HOST, MYSQL_USER, MYSQL_PASSWORD) or
    die ('Unable to connect. Check your connection parameters.');

mysql_select_db(MYSQL_DB, $db) or die(mysql_error($db));

$action = (isset($_GET['action'])) ? $_GET['action'] : '';
$article_id = (isset($_GET['article_id']) && ctype_digit($_GET['article_id'])) ?
    $_GET['article_id'] : '' ;

$title = (isset($_POST['title'])) ? $_POST['title'] : '' ;
$article_text = (isset($_POST['article_text'])) ? $_POST['article_text'] : '' ;
$user_id = (isset($_POST['user_id'])) ? $_POST['user_id'] : '' ;

if ($action == 'edit' && !empty($article_id)) {
    $sql = 'SELECT
            title, article_text, user_id
        FROM
            cms_articles
        WHERE
            article_id = ' . $article_id;
    $result = mysql_query($sql, $db) or die(mysql_error($db));

    $row = mysql_fetch_array($result);
    extract($row);
    mysql_free_result($result);
}
?>
