Link Form Field Filters

The link field searches your site's posts when a user looks for a page to link to. Three filters change that search.

Post Types

The siteorigin_widgets_search_posts_post_types filter receives the array of post types the field searches. The field searches every public post type except attachments. This example removes products from the search:

add_filter(
    'siteorigin_widgets_search_posts_post_types',
    function ( $post_types ) {
        return array_diff( $post_types, array( 'product' ) );
    }
);

Results

The siteorigin_widgets_search_posts_results filter changes the search results, so you can remove or sort them. The field returns up to 20 published posts, and each result is an array with value (the post ID), label (the post title) and type (the post type). After you remove items, return the array through array_values() so the field receives a list:

add_filter(
    'siteorigin_widgets_search_posts_results',
    function ( $results ) {
        foreach ( $results as $id => $result ) {
            // Your code here.
        }
        return array_values( $results );
    }
);

Sort Order

The siteorigin_widgets_search_posts_order_by filter changes the ORDER BY clause of the search, which is post_modified DESC unless you change it. Return a valid ORDER BY clause for the posts table:

add_filter(
    'siteorigin_widgets_search_posts_order_by',
    function ( $ordered_by ) {
        return 'post_modified ASC';
    }
);
