WP filter hooks

This plugin is quite configurable and provides lots of wp filter hooks from returned data in responses for each endpoint to params validation and endpoint permissions.

add_filter( 'wprm/get_menus/wp_get_nav_menus/args', 'my_wp_get_nav_menus', 10, 1 );
(used in GET /menus/v1/menus)

function my_wp_get_nav_menus( $args ) {
    // do something with wp_get_nav_menus $args array
    return $args;
}



add_filter( 'wprm/get_menus', 'my_get_menus', 10, 1 );
(used in GET /menus/v1/menus)

function my_get_menus( $menus ) {
    // do something with $menus array

    return $menus; // WP_Error|WP_HTTP_Response|WP_REST_Response|mixed
}



add_filter( 'wprm/get_menu_locations', 'my_get_menu_locations', 10, 1 );
(used in GET /menus/v1/locations)

function my_get_menu_locations( $locations ) {
    // You can modify the $locations array response (get_registered_nav_menus())

    return $locations; // WP_Error|WP_HTTP_Response|WP_REST_Response|mixed
}



add_filter( 'wprm/get_menu_items', 'my_get_menu_items', 10, 1 );
(used in GET /menus/v1/menus/<id>)

function my_rest_menu_item_fields( $menu ) {
    // You can modify the $menu items

    return $menu;
}



add_filter( 'wprm/get_location_menu_items', 'my_get_location_menu_items', 10, 1 );
(used in GET /menus/v1/menus/<id>)

function my_get_location_menu_items( $menu ) {
    // You can modify the locations $menu items

    return $menu;
}



add_filter( 'wprm/get_item_fields/filter_fields', 'my_filter_fields', 10, 1 );
(used to filter return field -node edges-)

function my_filter_fields( $fields ) {
    // You can modify the $fields array so
    // you can filter the return fields for all endpoints
    // without using the url param ?fields

    $fields = array( 'ID', 'title' );
    return $fields;
}

In newer version these two edges will co exist and the plugin will separate natively registered custom fields ad acf registered ones.
