Have an opencart store.
Need a script written that allows me to upload a SKU or MODEL Number into multiple categories without overwriting the previously assigned categories.
Example- Product 22 is assigned to category 1
I need to reassign Product 22 to category 5 and sub category 2.
The product 22 will then be assigned to Cat. 1 and 5-2 now.
You must be familiar with the OC structure. It's 1.5.2 version
