Fee if certain items are ordered

[Lanbo]

Hello. I tried searching for an answer for a few days but couldn't come up with anything. I need to be able to add a special fee for certain items to cover the extra shipping cost incurred. Basically if someone places an order for normal items, there would be no fee. But I need a way to add a fee to the order if these other items are ordered no matter how many of them are ordered. For example let's pretend that I have just two types of items: type A and type B. Type A items are just normal and you pay regular shipping based on weight. Type B items you still pay regular shipping based on weight but they need a $5 fee per order no matter how many are ordered. If both types are ordered then you still pay the $5 fee per order. And I don't care where the fee is placed whether it's in the shipping, handling, low order, etc. I'm not picky, just as long as it works I'll be happy.

Any help would be appreciated...and I don't mind having to modify anything if necessary.

Thanks guys and gals.

Let's say you were customizing the Flat Rate flat shipping module, you could use this code:

// bof: add additional charge if products 12 or 15 are in the cart
      global $cart;
      $chk_products = 0;
      $extra_shipping = 0.00;
      $chk_products += $_SESSION['cart']->in_cart_check('products_id','12');
      $chk_products += $_SESSION['cart']->in_cart_check('products_id','15');
      if ($chk_products > 0 ) {
        $extra_shipping = 5.00;
      }
      $this->quotes = array('id' => $this->code,
                            'module' => MODULE_SHIPPING_FLAT_TEXT_TITLE,
                            'methods' => array(array('id' => $this->code,
                                                     'title' => MODULE_SHIPPING_FLAT_TEXT_WAY,
                                                     'cost' => MODULE_SHIPPING_FLAT_COST + $extra_shipping)));
// eof: add additional charge if products 12 or 15 are in the cart

Thank you.

Would this work for other shipping modules...notably UPS and USPS?

Also, would it be possible to make a new column in the database under products such as products_fee and have it add the fee if the value is set to 1? I have quite a few and it would be easier to do it that way rather than telling it every products_id.

Thanks again.

There is always a way to customize the code ... this is Zen Cart ...

You can add new fields to figure out when to use the extra charge but you would have to write something to check if that field is set in any of the Products in the order ...

So, modifying your code, if I did do that, should the below work? And if I were using the UPS or USPS modules, would I just replace the MODULE_SHIPPING_FLAT_* stuff with the appropriate replacements?

// bof: add additional charge if products with products_fee value of 1 are in the cart
      global $cart;
      $chk_products = 0;
      $extra_shipping = 0.00;
      $chk_products += $_SESSION['cart']->in_cart_check('products_fee','1');
      if ($chk_products > 0 ) {
        $extra_shipping = 5.00;
      }
      $this->quotes = array('id' => $this->code,
                            'module' => MODULE_SHIPPING_FLAT_TEXT_TITLE,
                            'methods' => array(array('id' => $this->code,
                                                     'title' => MODULE_SHIPPING_FLAT_TEXT_WAY,
                                                     'cost' => MODULE_SHIPPING_FLAT_COST + $extra_shipping)));
// eof: add additional charge if products with products_fee value of 1 are in the cart

If the goal is if 1 or more Products are marked as:
products_fee = 1

then that will add $5.00 to the cost ...

I'm trying to put this in the USPS module but I cannot get it to work. I changed MODULE_SHIPPING_FLAT* to MODULE_SHIPPING_USPS* assuming that was correct. I'm also not 100% certain where to put it at. Either way, whatever I did isn't working.

It should look like this for USPS make sure you do not miss adding the $extra_shipping to the cost line ...

// bof: add additional charge if products with products_fee value of 1 are in the cart
      global $cart;
      $chk_products = 0;
      $extra_shipping = 0.00;
      $chk_products += $_SESSION['cart']->in_cart_check('products_fee','1');
      if ($chk_products > 0 ) {
        $extra_shipping = 5.00;
      }

          $methods[] = array('id' => $type,
                             'title' => $title,
                             'cost' => ($cost * $shipping_num_boxes) + (MODULE_SHIPPING_USPS_HANDLING_METHOD == 'Box' ? $usps_handling_fee * $shipping_num_boxes : $usps_handling_fee) + $extra_shipping );
// eof: add additional charge if products with products_fee value of 1 are in the cart

After I realized that it was obvious I was supposed to alter the existing section rather than adding the entire thing in extra it works perfectly. Thanks again.

Thanks for the update that this is now working for you ...
