Profile Builder Pro

Relevanssi can index extra fields created with Profile Builder Pro. All you need to do is add the custom fields’ names to the Relevanssi setting “User fields to index” (this is a Premium feature, so you need to have Relevanssi Premium). You can find the names of the fields from the Profile Builder > Manage Fields page: use the value in the “Meta Name” column.

Relevanssi doesn’t know how to use the extra fields in excerpts. This code adds all indexed fields to the user profile content before Relevanssi builds the excerpts using the relevanssi_pre_excerpt_content filter hook:

add_filter( 'relevanssi_pre_excerpt_content', 'rlv_profile_builder', 10, 2 );
function rlv_profile_builder( $content, $post ) {
    if ( isset( $post->user_id ) ) {
        $fields = get_option( 'relevanssi_index_user_fields' );
        if ( !empty( $fields ) ) {
            $fields_array = explode( ',', $fields );
            foreach( $fields_array as $user_field ) {
                $field_content = get_user_meta( $post->user_id, $user_field, true );
                $content .= ' ' . $field_content;
            }
        }
    }
    return $content;
}

Permalinks are another problem. By default, the permalinks in search results point to the site front page. Switching the permalinks on the theme search results template to use relevanssi_get_permalink() instead of get_permalink() or the_permalink() will help a bit, but not enough: now the links point to the WordPress user profile pages. However, Profile Builder Pro profile pages will use a different URL structure. Another filter function is needed:

add_filter( 'relevanssi_user_profile_to_post', 'rlv_adjust_url' );
function rlv_adjust_url( $user ) {
    $user->link = '/url/to/user/' . $user->user_id . '/';
    return $user;
}

Change the /url/to/user/ to match the URL structure used on your site. This change requires you to use relevanssi_get_permalink() to display the permalinks, the_permalink() or get_permalink() will not work.

Profiles created by Profile Builder Pro front end forms do not get automatically indexed by Relevanssi because the user account generation process in Profile Builder Pro doesn’t probably trigger all the filter hooks WP does. Thus Relevanssi overlooks the new user profiles Profile Builder Pro generates.

Profile Builder Pro has an action hook that you can use to nudge Relevanssi a bit. Just add this code to the theme functions.php, and Relevanssi will notice the new users and will index them:

add_action( 'wppb_register_success', 'rlv_index_wppb_users', 20, 3 );
function rlv_index_wppb_users( $http_request, $form_name, $user_id ){
    relevanssi_index_user( $user_id, false );
}
