Problem

I have product category which I did by types plugin 'custom taxonomies'. I want to show products by category when somebody clicks the category name that should show just that products which registered to for example "acril" category. Problem is when I am debugging products it is not showing category. So I should connect both foreach circle if you paid attention I have data-filter in circle 1 and data-cat in the second circle with value 'category'. that should be dynamic and what can be key for that connection if post not showing the any keys.

Answer 1

You need to pass the category name as well if you want to show posts from specific category..

You just need to add one more param to the get_posts array.

REPLACE THIS

<? $products = get_posts( array('post_type' => 'products', 'posts_per_page' => 400,) ); ?>

WIth THIS

<? $products = get_posts( array('post_type' => 'products',  'category_name' => 'category_name_here', 'posts_per_page' => 400,) ); ?>
