PHP Class Contao\Input

The class functions as an adapter for the global input arrays ($_GET, $_POST, $_COOKIE) and safely returns their values. To prevent XSS vulnerabilities, you should always use the class when reading user input. Usage: if (Input::get('action') == 'register') { $username = Input::post('username'); $password = Input::post('password'); } ファイルを表示 Open project: contao/core-bundle Class Usage Examples
