WP_Customize_Setting::multidimensional_replace() WordPress Method

The WP_Customize_Setting::multidimensional_replace() method is used to recursively update a multidimensional array of Customizer settings. This is useful when replacing settings with updated values, or when resetting settings to their default values.

WP_Customize_Setting::multidimensional_replace( array $root, array $keys, mixed $value ) #

	final protected function multidimensional_replace( $root, $keys, $value ) {
		if ( ! isset( $value ) ) {
			return $root;
		} elseif ( empty( $keys ) ) { // If there are no keys, we're replacing the root.
			return $value;
		}

		$result = $this->multidimensional( $root, $keys, true );

		if ( isset( $result ) ) {
			$result['node'][ $result['key'] ] = $value;
		}

		return $root;
	}
