CASHOUT Posted August 9, 2011 Author Share Posted August 9, 2011 Could the problem be in the array_splice syntax? Quote Link to comment Share on other sites More sharing options...
the182guy Posted August 9, 2011 Share Posted August 9, 2011 On this line you're using a space in item id instead of an underscore: $_SESSION["cart_array"] = array(1 => array("item id" => $pid, "quantity" => 1)); Quote Link to comment Share on other sites More sharing options...
