Hi.
I want a modification that limits the views of images to 20 to all unregistred users.
I'm trying to adapt an other mod of this forum but I'm not a PHP guru... so I would need you to help me.
// Step 1
In root dir create : install_user_limits.php.
Insert :
[code]
<?php
session_start();
define('ROOT_PATH', './');
include(ROOT_PATH.'config.php');
include(ROOT_PATH.'global.php');
include(ROOT_PATH.'includes/constants.php');
require(ROOT_PATH.'includes/sessions.php');
if (!isset($_SESSION[‘count’]))
{
$_SESSION[‘count’]=0;
}
$error_log = array();
$error_msg = "";
if ($action == "modinstall") {
?>
