In a seperated file I have an function that checks if an GET or POST statement exist, and If it exist and is not NULL then it will give the value back to where it was called. public function getFormVariable($value){ switch (strtoupper($_SERVER['REQUEST_METHOD'])) { case 'GET': if (isset($_GET[$value]) && $_GET[

问题 I m sending some form data (with get) to a popup with a javascript function. Both pages have utf-8 encoding. But popup showing special values wrong (like �).

问题 I am using this code, but it catches an error in a try-catch. Where is a mistake? When I print a error, content.setText(ex.getMessage()); is empty.
