Shipping Rate

[shotgun]

When checking out, or doing shipping estimate, can I add a function to flat.php to disable flat rate shipping if say, more than 3 items are in cart, if so, help a little please.
On another note, I have 10 heavy items that I gave the same manufacturers name, could I also disable flat shipping if any of those items are in the cart, thanks for any help in adavance.

just a hint where I'm going with this, in flat.php I've added, but can't figure where to get the product id to feed the function

// disable if has manufacturer
if (zen_not_null(zen_get_products_manufac(PRODUCT)))
{
$this->enabled = false;
}


/* in general.php I created a function */
function zen_get_products_manufac($product_id,$language_id)
{
global $db;
$product = $db->Execute("select manufacturers_id
from " . TABLE_PRODUCTS_DESCRIPTION . "
where products_id = '" . (int)$product_id . "'
and language_id = '" . (int)$language_id . "'");

return $product->fields['manufacturers_id'];
}

Changing the code from:

      // disable only when entire cart is free shipping
      if (zen_get_shipping_enabled($this->code)) {
        $this->enabled = ((MODULE_SHIPPING_FLAT_STATUS == 'True') ? true : false);
      }

to read:

      // disable only when entire cart is free shipping
      if (zen_get_shipping_enabled($this->code)) {
        $this->enabled = ((MODULE_SHIPPING_FLAT_STATUS == 'True') ? true : false);
      }
    global $cart;
    // disable when manufacturers_id = 3 is in cart for 1 or more products or number of items > 3
    if (IS_ADMIN_FLAG == false && ($_SESSION['cart']->in_cart_check('manufacturers_id','3') > 0 || $_SESSION['cart']->count_contents() > 3) ) {
      $this->enabled = false;
    }

will disable Flat Rate flat when 1 or more Products are in the cart using manufacturers_id = 3 ... or the item count > 3 ...

I bow to you Ajeh, just perfect, thank you.

Where could I set only one item in the cart from the same manufacturer, thanks again.

Could you be a bit more specific on what you are asking for?

Are you trying to do this for just 1 Product that happens to be from this manufacturer? Or are you trying to do something else?

If just 1 Product, then you could just check for that products_id for the Product ...
