How can i limit shipper for liquid products

[jodean]

I ship some products which are liquid and must be shipped UPS. How can I select UPS for liquid products?

Nothing is built in for this, you'll have to create some custom code.

Have a look at l big royal mai. I added attributes to limit shipping. You could do something similar with your shipping methods.

buy the fantastic advanced shipper mod, it's worth it, we've been using it for years and couldn't function without it.

I have perhaps a solution. I use it for a type of "letterbox-package". I made a zones variant for it and added code to disable that module if certain categories are found in the cart.

Since you permanently have to disable other shipping modules than UPS for it, it could work for you too. However some conditions come with this:

• all liquids must be in a category or categories by themselves
• you can not do it in the admin panel
• you'll have to edit some files

So, if you do this: backup your files first!

Example category is 5, adjust this to your category.
Insert following code in the modules you don't want to ship liquids in:

      // bof skip certain categories
      if (IS_ADMIN_FLAG == false && $_SESSION['cart']->in_cart_check('master_categories_id','5') > 0) {
          $this->enabled = false;
      }
      // eof skip certain categories 

in zones I placed it under:

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

If there's more than one category, repeat the code with the next category and so on. I tried using '1' || '2' || '3' instead of '5' to exclude 1, 2 and 3 but that fails to work properly.

It has to be placed where the code is for checking if the module has to be shown.

Good idea, I will try it even though I dont like changing code. I am surprised ZenCart has not addressed this issue. Its common knowledge that certain products must be shipped by specific shippers in the USA.

I took another look at the code and for my use I needed limitations to different quantities.
The code could cleaner for an overall limitation to zero.

    // bof skip certain categories
        if (IS_ADMIN_FLAG == false)  {
            if ($_SESSION['cart']->in_cart_check('master_categories_id','5') == true) {
                $this->enabled = false;
            }
            }
    // eof skip certain categories 

Example is category 5, adjust as needed.

I also thought you could have use for Numinix Product Fields if you add the product field "Products condition". If all liquids are therein marked as "liquid", you could use:

    // bof skip liquids
        if (IS_ADMIN_FLAG == false)  {
            if ($_SESSION['cart']->in_cart_check('products_condition','liquid') == true) {
                $this->enabled = false;
            }
            }
    // eof skip liquids 

Than you don't need to enter a lot of code for every category, leave products in every category according to other criteria and still grab them all as liquids.

Always test in a test environment or test site.

Which PHP file is this code supposed to be placed?
