Add content in between product rows in WooCommerce archives

Question

I want to show some content after the third product (and maybe the sixth, ninth...) of a product category. Not every category has that extra content or the same amount of it

Answer 1

Updated - Instead of overriding a template file, you can use the following hooked function, that will add a custom content full row in between each products row:

add_action( 'woocommerce_shop_loop', 'action_woocommerce_shop_loop', 100 );
function action_woocommerce_shop_loop() {
    // Only on producy cayegory archives
    if ( is_product_category() ) :
        
    global $wp_query;
    
    // Get the number of columns set for this query
    $columns = esc_attr( wc_get_loop_prop( 'columns' ) );
    
    // Get the current post count 
    $current_post = $wp_query->current_post;
    
    if ( ( $current_post % $columns ) == 0  && $current_post > 1 ) :
    
    ?>
