My custom posts that are assigned to categories, are not called on a category search using a Category Menu

Question

I used the Custom Post UI plugin to create a custom post type called 'business_sold'. I assigned each custom post to one of six categories and an additional one called 'All'.

I used a standard WP widgetized menu to list the 'Business Sold' categories, but my custom posts are not called on a search of any category. I can see that WP has recognized the category assignment. Single-business_sold.php is working fine, but neither category-business_sold or archive-business_sold are working.

I cannot figure out what I'm doing wrong. Can anyone help me please?

Answer 1

Category archive by default it search for posts and not your custom type, you need to tell WordPress to search for your custom type, paste this code in your theme's functions.php file:

function cpt_Search_category_Filter($query) {
    $post_type = array('post','business_sold');
    if ($query->is_search || $query->is_category) {
        $query->set('post_type', $post_type);
    };
    return $query;
};

add_filter('pre_get_posts','cpt_Search_category_Filter');

and you should be fine.
