perweightunit issue

[vanhorn_s]

If you knew you wanted Category A to have shipping costs of:
$4.95 * quantity ...

and then the rest of the shop to be based on the Per Unit perweightunit shipping module ... that could be done with a calculation added to the Per Unit perweightunit shipping module ...

If the 1 Category could be done by USPS ... why can't the rest of the Products?

apparently i am not clarifying very well. all of the products that are in category 1 fit perfectly into the usps large flat rate box, by themselves. if someone wants to buy multiple quantities, or would rather use ups, i want the calculated shipping for ups, and usps to remain as an option.

all i want, is the large flat rate box to be exclusive to shopping carts that only contain products from category 1.

at this point, i don't sell anything that won't fit into those boxes, but i plan on it in the near future, which is why i am trying to do this now.

Try to picture this ...

If all Products in the Category 1 are 1 per box for $4.95 ... and are setup with 0 weight ...

and if all other Products not in Category 1 have their shipping cost in the Product weight field ...

You can then customize the Per Unit perweightunit that works for everything else to count how many Products are from categories_id via the master_categories_id of the Product and multiply them by 4.95 and add them to the cost calculated by the Per Unit perweightunit shipping module ...

So if I buy 1 Product A which is in Category 1 and 3 of Product D which is in Category 1 I would have 4*4.95 ... then whatever the Per Unit perweightunit is currently calculating is added to this amount ...

Would that be the correct calculation?

[vanhorn_s]

that would work.

i still would like to use ups, and usps shipping modules, because when a customer orders multiple items, i will put as much in one package as i can. using per weightunit only will not give the customer the best price option. all i need to do, is make my flat rate dissapeer as an option for other categories,and carts mixed with other categories, like the free shipping module does for shopping carts with items that don't have a free option.

i apologize for this. i know it started as one thing, then turned into something else, and i seem to be making this difficult.

You need to make a choice ...

Do you want Category 1 to be $4.95 per Product per quantity plus use normal weight on the other Products so that you can use UPS and USPS ...

Or ... do you want Category 1 to be $4.95 per Product per quantity plus use Per Unit perweightunit shipping module where all other Products have their shipping cost put into the Product weight ...

Or ... do you want something totally different ...

You have me really lost where you want to go with all this ...

[vanhorn_s]

i'm really sorry, i had no intention of confusing you.
All of the products in category 1 weigh an actual 10 pounds packaged. if you order 1 set, the best option for me to ship is the large flat rate box. my cost $13.95 i currently mark it up to $18.50, and use the perweightunit at 1.85 i also have the ups, and usps modules activated.
The price that i sell the items for in category 1, are either $146.95, or $224.95, depending on what style they buy.

if a customer purchases 4 items from that category, usually the regular priority mail rate for 40 pounds is considerably less than the 4 flat rate boxes, which would be $74.

all i need, is a shipping option that will charge $18.50 per item, and will only be visible when items from category 1 are the only things in the cart.

also, i don't want to raise the weight limit, because i want large orders split into multiple packages if the customer chooses ups, or another usps shipping option.


if you can't help me, i'll just deal with the problem when i go to add more products that will be too big for the large flat rate box.

This will count how many products are in the cart from categories_id 1 when the master_categories_id of the Product is set to 1:

if (!IS_ADMIN_FLAG) {
  global cart;
  $chk_cat_1 = $_SESSION['cart']->in_cart_check('master_categories_id','1');
}

Then, using the value $chk_cat_1 you can multiply that by whatever price you want to charge ...

Then, find the cost setting in the shipping module and add that to it ...

Example: in the USPS shipping module you would see the code:

          $methods[] = array('id' => $type,
                             'title' => $title,
                             'cost' => ($cost * $shipping_num_boxes) + (MODULE_SHIPPING_USPS_HANDLING_METHOD == 'Box' ? MODULE_SHIPPING_USPS_HANDLING * $shipping_num_boxes : MODULE_SHIPPING_USPS_HANDLING) );

This can be changed to:

          $methods[] = array('id' => $type,
                             'title' => $title,
                             'cost' => (($cost * $shipping_num_boxes) + (MODULE_SHIPPING_USPS_HANDLING_METHOD == 'Box' ? MODULE_SHIPPING_USPS_HANDLING * $shipping_num_boxes : MODULE_SHIPPING_USPS_HANDLING) + ($chk_cat_1 * 18.95)) );

This would then add the $18.95 per Product per quantity to the USPS shipping quote rate based on the idea that all Products in Category 1 have 0 weight to them ...

NOTE: the USPS shipping module will get a quote based on the lowest possible rate when there is 0 weight in the cart ...

You could disable the USPS shipping module with similar code, based on the Category 1 being the only products in the cart with by changing the code:

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

if (!IS_ADMIN_FLAG) {
  global cart;
  $chk_cat_1 = $_SESSION['cart']->in_cart_check('master_categories_id','1');
  if ($chk_cat_1 == $_SESSION['cart']->count_contents()) {
    $this->enabled = false;
  } 
}

Adapting this code can then control which shipping modules show or do not show based on the content of the cart ...

thank you very much. i will try to implement this later today.

[vanhorn_s]

the second code you gave me, the one for disabling the usps shipping module, makes the entire shipping quote section disapeer.

That's cause of that silly little typo ...

global cart;

needs to be:
global $cart;

See if that works a bit better ...

NOTE: the global $cart; needs the $cart and not cart in both places ...
