add_option_whitelist() WordPress Function

The add_option_whitelist() function is used to add a new whitelisted option to the list of options that are safe to update via the Settings API. This is useful for plugins that want to add their own settings pages and allow users to update them without having to worry about accidentally overriding any of WordPress's built-in settings.

add_option_whitelist( array $new_options, string|array $options = '' ) #

function add_option_whitelist( $new_options, $options = '' ) {
	_deprecated_function( __FUNCTION__, '5.5.0', 'add_allowed_options()' );

	return add_allowed_options( $new_options, $options );
}
