I spoke to masterblaster about this yesterday, you need to replace all the code in this file includes/modules/minorderamount.php
with the following code
Code:
<?php
// BOF MIN ORDER AMOUNT
// check order total minimum
if(substr($_GET['main_page'], 0, 8) == 'checkout' && substr($_GET['main_page'], 0, 16) != 'checkout_success') {
if ($_SESSION['cart']->total < MIN_ORDER_AMOUNT) {
zen_redirect(zen_href_link(FILENAME_SHOPPING_CART, '', 'NONSSL'));
}
}
?>
Works brilliantly, and what a great mod, still amazed this isn't included in the 1.3x version of ZC.
