This is my PHP u.php

Code: <?php
include 'dbc.php';
page_protect();
session_cache_limiter('private,
must-revalidate');
header('private, must-revalidate');
if (!isset($_SESSION['user_id'])) {
$e = "";
}
$title = $_POST['title'];
$text = $_POST['prayer'];
$time = date("D, M j Y, h:ia");
$name = $_POST['name'];
if(trim($_POST['title'])=='' || strlen(trim($_POST['title'])) > 30 || strlen(trim($_POST['title'])) > 30){
echo "Please enter a Title between 3 and 30 characters!<br />"; //concatenate the $error Message with a line break
exit;
}
//maybe dont need $private = $_POST['private'];
if(trim($_POST['name']) > 20){
echo "Please enter a username between 3 and 20 characters!<br />"; //concatenate the $error Message with a line break
exit;
}

$key=substr($_SESSION['key'],0,3);
$number = $_REQUEST['number'];
if($number!=$key){
echo '<center><font face="Verdana, Arial, Helvetica, sans-serif" color="#FF0000">
Validation string not valid! Please try again!</font></center>';

exit;
}

else
{
unset($_SESSION['key']);

/*
if (!isset($_SESSION)) {
session_start();
}
// anti flood protection
if(isset($_SESSION['lol']) && $_SESSION['lol'] > time() - 30){
// users will be redirected to this page if it makes requests faster than 2 seconds
echo "Stop flooding please";
exit;
}
$_SESSION['lol'] = time();
*/
mysql_query("INSERT INTO `prays` (`title`,`prayer`,`time`,`level`,`nameid`,`name`) VALUES (
'". mysql_real_escape_string($_POST['title']) ."',
