add_settings_error( string $setting, string $code, string $message, string $type = 'error' )

描述

Part of the Settings API. Use this to show messages to users about settings validation problems, missing settings or anything else.

Settings errors should be added inside the $sanitize_callback function defined in register_setting() for a given setting to give feedback about the submission.

By default messages will show immediately after the submission that generated the error. Additional calls to settings_errors() can be used to show errors even when the settings page is first accessed.

The formatted message text to display to the user (will be shown inside styled div and p tags).

$type

(Optional)
Message type, controls HTML class. Possible values include 'error', 'success', 'warning', 'info'.
