Webformulare Sichern
Auf net.tuts+ gibt es eine Einführung wie man Webformulare mit Form Keys absichern kann.
We’ll add a special hash (a form key) to every form to make sure that the data will only be processed when it has been sent from your website. After a form submit, our PHP script will validate the submitted form key against the form key we’ve set in a session.
