I am making an e-commerce website with wordpress and there are a few things that are stressing me. I would like to have a custom single page for each product category. How do I do that?
You can create a new page on Wordpress, and add a shortcode there:
[product_category category="category-slug"] - just replace the "category-slug" with the category slug of yours. You can view the slug at Product > Categories in the admin menu.
This shortcode will display all products in a specified category. You can repeat this and create as many pages for as many categories as you want.
