As the method for the form is GET, if QuickForm notices that values are passed using GET (in the url), it will validate the form. The same applies to POST. The workaround is to set an hidden element in the form and testing for its existence before calling validate: $form->setConstants(array('formname' => 'loginform')); $form->addElement('hidden', 'formname'); ... If ($form->getElementValue('formname') == 'loginform' && $form->validate()) ... This way, validate will never be called if the submitted form does not contain a hidden field 'formname'. We use setConstants() so that the user can't cheat and override the element value. We use getElementValue() because it returns the constant value if any. The other solution is to wait for the HTML_QuickForm_Controller class that's coming soon :) Bertrand Mansion Mamasam
