Shipping per Categories

[Ajeh]

You would have to control how much is being charged in this section:

      $chk_total_charge_constant = constant('MODULE_SHIPPING_ITEMCAT_COST' . $i);
      $chk_total_charge += ($chk_total_charge_constant * ${$chk_cat_group});
      $chk_total_count += ${$chk_cat_group};

The price is set in:
$chk_total_charge_constant

you would want to change that from the amount you set per sheet of 2.50 to the lower amount of 0.40 when the count:
$chk_total_count

is at the number of sheets where you want to charge less ...

Keep in mind that the count:
$chk_total_count

is set after the charge is calculated ... so when the first item is calculated the count is 0 ...

Plus, you have to decide if all of the item counts when > 1 get changed to 0.40 or if you want different charges for the groups as it could get complicated to figure out the:
$chk_total_charge_constant

[missinglife]

so I have to write a "IF" statement?

Yes, you will need an IF in this section of the code ...

I would start by rearrange that section of code as:

      $chk_total_count += ${$chk_cat_group};
      $chk_total_charge_constant = constant('MODULE_SHIPPING_ITEMCAT_COST' . $i);
      $chk_total_charge += ($chk_total_charge_constant * ${$chk_cat_group});

so you can better tell if you are on sheet 1 or sheet 2, sheet 3 etc.

Then, you have to decide when/what to use the cost setting for:
$chk_total_charge_constant

the issue is how much to charge based on the count but you are dropping the rate based on count from 2.50 to 0.40 ...

The difficulty is, this is using multiple rates based on the Category ... it wasn't written to suddenly decide to charge different rates for different quantities for different categories ...

You have some categories for 2.50 and some categories for 0.46 ... then, you suddenly want on the categories for 2.50 to only charge the 2.50 if it is 1 sheet but then charge a different price of 0.40 if there are more than 1 sheet ...

But, this is not the same logic for all of the category groups, meaning that on the categories for the 2.50 you want 2.50 for sheet 1 and 0.40 for sheet 2+ but on the categories for 0.46 you want 0.46 for sheet 1 and 0.46 for sheet 2+ ...

I am not sure just how hard it will be to do that with the multiple categories settings ...

The main idea is to get the:
$chk_total_charge_constant

set to the right amount to charge for the sheet for the right category group at the right time ...

You will really need to work with that section to get the IF right on how much to charge ...

This is over my head, I dont think I can do any of what you suggested above
is there a shipping module will work for my situation? or do I need to pay someone to do this for me?

I am hoping to get this shipping module done, so I can upgrade to the new version of Zen Cart.

thank you so much for your help!

[Ajeh]

You could try this to charge sheet 1 2.50 and 0.40 sheet 2+ in category group 1 and charge sheet 1 0.46 and 0.40 sheet 2+ in category group 2

      $chk_total_count += ${$chk_cat_group};
      $chk_total_charge_constant = constant('MODULE_SHIPPING_ITEMCAT_COST' . $i);
//      $chk_total_charge += ($chk_total_charge_constant * ${$chk_cat_group});
      $chk_total_charge += (${$chk_cat_group} > 0 ? (1 * $chk_total_charge_constant) + ( (${$chk_cat_group} - 1) * .40) : 0);

It should work but you will need to test it ...

[missinglife]

it works for US and Rest of World shipping, Yay!!!!

however Canada shipping is not, it seems it charge the same shipping fees as US shipping.
I am not sure where I did wrong on itemcatcan.php, can you take a look?

Thank you!!!

I believe this line:

      $chk_total_charge_constant = constant('MODULE_SHIPPING_ITEMCAT_COST' . $i);

should be:

      $chk_total_charge_constant = constant('MODULE_SHIPPING_ITEMCATCAN_COST' . $i);

Ajeh Oba San -

(giddy with excitement). Will this mod you wrote work in the case when:

1. I have 3 clones of the Zone Rates working just fine
2. Setting a Per Unit (or other shipping module) to a specific category
3. When a use adds two different products from different categories, the shipping adds fine in the cart?

thanks a bunch!
