The e-commerce.

per item math - charge$10 per every 3 items - will it work?


Recommended Posts

This is my shipping costs:

1-3 items - $10.00

4-6 items - $20.00

7-9 items - $30.00



Using the per item will not quite work for me because I am using an even number shipping amount per odd number of items.

In the per item shipping module I think this is the code I need to modify:



I had a javascript cart once that I had shipping calculated like this:

((Math.ceil(fItems/3 ))*10);


Will this work:

'cost' => (MODULE_SHIPPING_ITEM_COST * (Math.ceil($total_count/3 ))*10) + MODULE_SHIPPING_ITEM_HANDLING)));

did it again...posted without really trying on my own first.


PHP does not use Math.ceil() like javascript. All that is needed is ceil()


This is now my modification and it works:

'cost' => (MODULE_SHIPPING_ITEM_COST * (ceil($total_count/3 ))) + MODULE_SHIPPING_ITEM_HANDLING)));
