Beste,

Weet iemand misschien hoe ik de variabele kan ophalen. Ik vraag op $test. Maar er staat niks?

In de public function ShowDomains() moet je global $test; zetten.

                  [URL="http://www.php.net/echo"]echo[/URL] [COLOR= #0000BB]$test[/COLOR][COLOR= #007700];

         }[/COLOR]

Of je doet gewoon $this->test in plaats van $test.. Buiten dat moet je geen waardes echoen binnen classen, je moet ze returnen. Ander krijg je alleen maar slechte code.

Dank je.
