WP_REST_Meta_Fields::prepare_value_for_response( mixed $value, WP_REST_Request $request, array $args )
Prepares a meta value for a response.
Description
This is required because some native types cannot be stored correctly in the database, such as booleans. We need to cast back to the relevant type before passing back to JSON.
Parameters
- $value
-
(mixed) (Required) Meta value to prepare.
- $request
-
(WP_REST_Request) (Required) Current request object.
- $args
-
(array) (Required) Options for the field.
Return
(mixed) Prepared value.
