JRequest::getVar

Fetches and returns a given variable.

The default behaviour is fetching variables depending on the current request method: GET and HEAD will result in returning an entry from $_GET, POST and PUT will result in returning an entry from $_POST. You can force the source by setting the $hash parameter: post $_POST get $_GET files $_FILES cookie $_COOKIE env $_ENV server $_SERVER method via current $_SERVER['REQUEST_METHOD'] default $_REQUEST
