WC displaying products from category

Question

I'm currently working on shop page and custom product loop. With WP_Query I can succesfully display products based on meta_key and meta_val but i run into trouble. Now i have to display all products from category and as argument i need to pass category_id. This is my code:

$args = array(
            'post_type' => 'product',
            'posts_per_page' =>12,
    //   get category by slug is working -
            'product_cat' =>  'products-from-cat-40',
          );

I know that woocommerce have slightly different query arguments than wordpress so i've tried so far:

• product_cat_id
• product_cat
• product_category
• product_category_id
• cat
• cat_id
• category_id

As ID i passed both integer and string but still nothing works. I've searched trough internet for list of viable Woocommerce WP_Query arguments and i couldn't find it. Can anyone help? I'll much appreciate.

For custom taxonomies, including Product Categories, you should use the tax_query argument:

$args = array(
    'post_type'      => 'product',
    'posts_per_page' => 12,
    'tax_query'      => array(
        array(
            'taxonomy' => 'product_cat',
            'terms'    => 40,
        ),
    ),
);
