WooCommerce, wordpress search, pre_get_posts filter exclude excerpt and product description


I am trying to modify the custom wordpress search by using pre_get_posts hook, so that a specific words won't be searched in product description.

add_action( 'pre_get_posts', 'exclude_search_content' );
function exclude_search_content( $Q ) {

    $search_phrase = $Q->query['s'];

    if( $Q->is_search() ) {
        /** Dont search for $search_phrase in excerpt and product description
        * search only product title, a meta key and a taxonomy.
        */
    }
}

It seems to be more complex than I expected. Any ideas?


Solution

  • if you check posts_search reference you will find some of Contribute already wrote similar function, so i just test it and it's working fine.

    function search_by_title_only($search, $wp_query)
    {
        global $wpdb;
        if (empty($search)) {
            return $search; // skip processing - no search term in query
        }
        $q = $wp_query->query_vars;
        $n = !empty($q['exact']) ? '' : '%';
        $search =
        $searchand = '';
        foreach ((array) $q['search_terms'] as $term) {
            $term = esc_sql($wpdb->esc_like($term));
            $search .= "{$searchand}($wpdb->posts.post_title LIKE '{$n}{$term}{$n}')";
            $searchand = ' AND ';
        }
        if (!empty($search)) {
            $search = " AND ({$search}) ";
            if (!is_user_logged_in()) {
                $search .= " AND ($wpdb->posts.post_password = '') ";
            }
    
        }
    
        return $search;
    }
    add_filter('posts_search', 'search_by_title_only', 20, 2);
