Flat Rate Shipping - Table Rates - Duplicate for Category Specific Items?

[limelites]

I have a bit of a dilemma since Royal Mail have raised changed their prices to extortion levels.

We had to increase our table rates across the whole site so that now the minimum UK shipping is £6.00, then we have £1.00 increases based on order value.

My dilema is with the ribbons that we sell as these are quite small and they do fit in the new cube sized boxes that Royal Mail will still post for under £4.00. Ideally, we would like to have our site set up so that customers checking out with only products from category ID 409 will be using a different table rate from anyone with products from a different category.

Is this even possible? If I were to duplicate the "Table" shipping module and call is say, Table409. How would I code the cart/checkout to differentiate between carts with only products from category 409 and all other carts?

Let's say you want Table Rate table to only show when the whole order is from master_categories_id 15 ...

Edit the shipping module:
/includes/modules/shipping/table.php

with the code in RED:

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

// bof: only show if all Products are from master_categories_id 15
  if (!IS_ADMIN_FLAG) {
    // check the count of a specific field
    $chk_catAll = 0;
    $chk_cat15 = 0;
    $chk_catAll = $_SESSION['cart']->count_contents();
    // check how many Products are in the cart for master_categories_id 15
    $chk_cat15 = $_SESSION['cart']->in_cart_check('master_categories_id','15');
    // if any are found turn off the shipping module
    if ($chk_cat15 != $chk_catAll) {
      $this->enabled = false;
    }
  }
// eof: only show if all Products are from master_categories_id 15

    if ($this->enabled) {
      // check MODULE_SHIPPING_TABLE_HANDLING_METHOD is in

For master_categories_id 409, change the 15 to 409 in each occurrence ...

I must be doing something wrong. Knowing me, it's probably something really stupid but I've cloned the table.php by following this thread:

http://www.zen-cart.com/showthread.p...hipping-module

I've called the file table409.php and created a corresponding language file. I've change all instances of "table" or "table2" to "table409" and all instances of "TABLE" or "TABLE2" to "TABLE409". Uploaded and voila, the shipping module appears as it should in admin.

When I install it in admin and enter the shipping rates for the products in category 409, it seems to completely disable both table.php shipping modules. Tha is to say, the flat rate UK shipping option just completely disappears from the checkout confirmation page, no matter what is in the cart.

Here is the code that I inserted in /includes/modules/shipping/table409.php, but I don' think the problem is caused by this:

// bof: only show if all Products are from master_categories_id 409
  if (!IS_ADMIN_FLAG) {
    // check the count of a specific field
    $chk_catAll = 0;
    $chk_cat409 = 0;
    $chk_catAll = $_SESSION['cart']->count_contents();
    // check how many Products are in the cart for master_categories_id 409
    $chk_cat15 = $_SESSION['cart']->in_cart_check('master_categories_id','409');
    // if any are found turn off the shipping module
    if ($chk_cat409 != $chk_catAll) {
      $this->enabled = false;
    }
  }
// eof: only show if all Products are from master_categories_id 409 

Here is a screenshot of the admin settings for both table.php and table409.php:

    }
  }
// eof: only show if all Products are from master_categories_id 409 

Here is a screenshot of the admin settings for both table.php and table409.php:

I've just triple checked everything and reinstalled and it still has the same issue. However, when I comment out the new category exclusion code, it stops the interference.

// bof: only show if all Products are from master_categories_id 409
//  if (!IS_ADMIN_FLAG) {
    // check the count of a specific field
  //  $chk_catAll = 0;
    //$chk_cat409 = 0;
    //$chk_catAll = $_SESSION['cart']->count_contents();
    // check how many Products are in the cart for master_categories_id 409
    //$chk_cat15 = $_SESSION['cart']->in_cart_check('master_categories_id','409');
    // if any are found turn off the shipping module
    //if ($chk_cat409 != $chk_catAll) {
     // $this->enabled = false;
   // }
 // }
// eof: only show if all Products are from master_categories_id 409 

With this commented out, I can then see the flat rate shipping option again. So, it's something to do with this code I'd say, or the way I've edited it?

Another quick update, with the new code commented out and both the new table409.php and the original table.php enabled, the checkout page doesn't show both options, only the new one. So, the cloned one seems to override the original one. I've no idea why.

You appear to have changed all of the $chk_cat15 to $chk_cat409 except one:

   $chk_cat15 = $_SESSION['cart']->in_cart_check('master_categories_id','409');
