Hi I'm trying to have an array to maintain the id's of some favourite items, like a shopping cart but no that complicated. I can't get it to add to the array tho, can anyone help? <?php // get id from url if (isset($HTTP_GET_VARS['setid'])) { $setid = (get_magic_quotes_gpc()) ? $HTTP_GET_VARS['setid'] : addslashes($HTTP_GET_VARS['setid']); } // check if cookie set and if so add new setid on the end if(isset($feature)) { echo $featureid; $featureid = $featureid .= ','.$setid; } else { // cookie not set yet // only one entry so add as is $featureid = $setid; } setcookie("feature", $featureid, time()+604800); /* Expires in a week */ $URL="./lightbox.php";header ("Location: $URL"); ?>
