rest_ensure_response() WP 1.0

Ensures a REST response is a response object (for consistency).

This implements WP_HTTP_Response, allowing usage of set_status/header/etc without needing to double-check the object. Will also allow WP_Error to indicate error responses, so users should immediately check for this value.

No Hooks.

Return

WP_REST_Response/Mixed. If response generated an error, WP_Error, if response is already an instance, WP_HTTP_Response, otherwise returns a new WP_REST_Response instance.

Usage

rest_ensure_response( $response );

$response(WP_HTTP_Response/WP_Error/mixed) (required)

Response to check.
