WP_REST_Server::json_error( string $code, string $message, int $status = null )

Retrieves an appropriate error representation in JSON.

Description

Note: This should only be used in WP_REST_Server::serve_request(), as it cannot handle WP_Error internally. All callbacks and other internal methods should instead return a WP_Error with the data set to an array that includes a ‘status’ key, with the value being the HTTP status to send.

Parameters

$code

(string) (Required) WP_Error-style code.

$message

(string) (Required) Human-readable message.

$status

(int) (Optional) HTTP status code to send.

Default value: null

Return

(string) JSON representation of the error

Source

File: wp-includes/rest-api/class-wp-rest-server.php 

protected function json_error( $code, $message, $status = null ) {
		if ( $status ) {
			$this->set_status( $status );
		}

		$error = compact( 'code', 'message' );

		return wp_json_encode( $error );
	}
