WP_REST_Settings_Controller::sanitize_callback( mixed $value, WP_REST_Request $request, string $param )
Custom sanitize callback used for all options to allow the use of ‘null’.
Description
By default, the schema of settings will throw an error if a value is set to null
as it’s not a valid value for something like "type => string". We provide a wrapper sanitizer to whitelist the use of null
.
Parameters
- $value
-
(Required) The value for the setting.
- $request
-
(Required) The request object.
- $param
-
(Required) The parameter name.
Return
(mixed|WP_Error)
