Different shipping methods for different categories

[everlost]

I have not used the Royal Mail shipping module but you should be able to customize it in a similar manner ...

Hmm, I've been struggling with this for a while now and can't seem to get it working.
I want to disable and hide the option of large letter shipping for a certain categories as they have items which are too thick to be posted at this rate.

At the moment my item.php reads as follows...

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

So I tried adding this code underneath...

// disable only when entire cart is free shipping
      if (zen_get_shipping_enabled($this->code)) {
       $this->enabled = ((MODULE_SHIPPING_RM1STLARGELETTER_STATUS == 'True') ? true : false);
      }
      // disable for one master_categories_id
      if ((IS_ADMIN_FLAG == false && $_SESSION['cart']->in_cart_check('master_categories_id','148') > 0)) {
          // show RM1STLARGELETTER
          $this->enabled = false;
      } else {
          // hide RM1STLARGELETTER
          $this->enabled = true;
       }

Like you showed for your UPS version...but nothing happened.
I know it that instance you said to put it in the UPS.php, but the rm1stlargeletter.php doesn't have this code in it to change...

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

Sorry to be a pain, but I really want to get this sorted as I can't afford to lose out by undercharging, but equally don't want to put people off by over charging for shipping. I have really tried to understand it, but I know that one of you clever people will probably see what I am doing wrong straight away and hopefully be able to steer me to a solution.
Thanks for any help you can offer.

In the code you provided is a line that reads in part:

$_SESSION['cart']->in_cart_check('master_categories_id','148') > 0))

Since you obtained this code from another example you may or may not have changed the master_categories_id number (148)... anyway, 1st thing to do is to ensure this number does actually match the category for where you want the module disabled.

Other than this, the code provided *appears* ok.

The id number 148 is indeed the correct one for the category which I want to disable the shipping method for. It is good to know that it the code seems ok, but if I can get it actually working too that will make my day...

This code needs to be placed in the module that you wish to disable. I'm guessing in your case this would be the rm1stlargeletter.php module .... SO, my next question is, if this module doesn't have the code in it to change, then exactly where did you add this code?

Cheers

I tried putting it in /includes/modules/shipping/item.php following post #9 by Ajeh.
I admit I was desperately trying to make it work by myself but when I realised it didn't work I removed all the modified code and it is back to normal. Any suggestions as where I should stick (no rude suggestions please)...

That'll work IF you were using the per item shipping module, but as per previous post, the code needs to be placed within the code that you are using.

Assuming it is a module called "rm1stlargeletter" that you are using, then the code needs to be placed into the rm1stlargeletter.php code.

This code SHOULD have a $this->enabled variable being set somewhere near the beginning of the code, so you just need to identify where and then place the additional code somewhere after that (similar to the example(s).

Cheers
Rod.

ps. I'm about to call it a night, so unless Ajeh steps in while I'm sleeping you are probably on your own...

Ok Rod, well thanks for your help so far.
I checked out the rm1stlargeletter.php and found the $this->enabled and placed the code under it (code I inserted is marked in red).

// class constructor
    function rm1stlargeletter() {

      global $order, $total_weight ;

      $this->code = 'rm1stlargeletter';

          $this->enabled = false;
      } else {
          // hide RM1STLARGELETTER

      // CUSTOMIZE THIS SETTING FOR THE NUMBER OF ZONES NEEDED

      if( isset($order) && MODULE_SHIPPING_RM1STLARGELETTER_HIDE_SHIPPING_ERRORS == 'True' ){

        switch(isset($order->info['subtotal'])){

        case true:
          if( $order->info['subtotal'] < MODULE_SHIPPING_RM1STLARGELETTER_MIN_ORDERVALUE){
              $this->enabled = false;
            return ;
          }else
          if(MODULE_SHIPPING_RM1STLARGELETTER_MAX_ORDERVALUE != -1 && $order->info['subtotal'] > MODULE_SHIPPING_RM1STLARGELETTER_MAX_ORDERVALUE){
              $this->enabled = false;
            return ;
          }

Still not working though...perhaps someone else will come along and give me some more pointers

Below this line:

      // disable for one master_categories_id

what happens if you add:

      // disable for one master_categories_id
     global $cart;

      // disable for one master_categories_id

Nothing happens, it still shows large letter as an option for posting items in that category :-/

Afraid I do not know what the rest of your code is doing based on the small piece that you are showing ...
