    if (ini_get('magic_quotes_gpc'))
{
    	$data = stripslashes($data);
    }
    return mysql_real_escape_string($data);
}

function insert_get_categories($a)
{
    global $config,$conn;
$query = "select * from categories order by name asc"; 
$results = $conn->execute($query);
$returnthis = $results->getrows();
return $returnthis;
}

function insert_get_advertisement($var)
{
        global $conn;
        $query="SELECT code FROM advertisements WHERE AID='".mysql_real_escape_string($var[AID])."' AND active='1' limit 1";
        $executequery=$conn->execute($query);
        $getad = $executequery->fields[code];
	echo strip_mq_gpc($getad);
}

function verify_login_admin()
{
        global $config,$conn;
        if($_SESSION['ADMINID'] != "" && is_numeric($_SESSION['ADMINID']) && $_SESSION['ADMINUSERNAME'] != "" && $_SESSION['ADMINPASSWORD'] != "")
        {
		$query="SELECT * FROM administrators WHERE username='".mysql_real_escape_string($_SESSION['ADMINUSERNAME'])."' AND password='".mysql_real_escape_string($_SESSION['ADMINPASSWORD'])."' AND ADMINID='".mysql_real_escape_string($_SESSION['ADMINID'])."'";
