[Done v1.5.4] PHP 5.4 PHP Warning: Creating default object from empty value

ksivv:

I using ZC v 1.5.1 and got exactly the same error

PHP Warning: Creating default object from empty value in /home2/footy/public_html/xxxx/categories.php on line 1015

> but adding the line didn't fix the problem. Error only happens when product set to Priced by Attributes. No errors for products without attributes.

Sorted. Problem was with Big Royal mail. I found fix in this trade: <http://www.zen-cart.com/showthread.php?198005-Big-Royal-Mail-3-0/page12>

$products_list = $_SESSION['cart']->get_product_id_list();

with

$products_list = '';
if (is_array($_SESSION['cart']->contents)) {
	reset($_SESSION['cart']->contents);
	while (list($products_id, ) = each($_SESSION['cart']->contents)) {
		$products_list .= ', ' . zen_get_prid(zen_db_input($products_id));
	}
}
$products_list = substr($products_list, 2);
