formBuilder:converting an auto generated date field in a hidden field

Hello, I have problems converting auto generated date fields (field of type date in db) in hidden fields. $el['mdate']=& HTML_QuickForm::createElement('hidden','mdate'); in preGenerateForm doesn't work well (*Warning*: htmlspecialchars() expects parameter 1 to be string, array given in *C:\wamp\php\PEAR\HTML\Common.php* on line *150). I suppose this is because "mdate" isn't really a field but is an array mdate[d], mdate[m]... $form->removeElement('mdate'); $form->addElement('hidden','mdate'); $form->setConstants(array('mdate'=>date('Y-m-d')); in *preGenerateForm() doesn't work either because a string ('2006-04-22') is passed to the array2date callback. Well, while writing this mail, I've tried an other solution ! I Finally succeded with this (in preGenerateForm()): $form->removeElement('mdate'); $form->addElement('hidden','mdate[Y]'); $form->addElement('hidden','mdate[m]'); $form->addElement('hidden','mdate[d]'); $form->setConstants(array('mdate[Y]'=>date('Y'),'mdate[m]'=>date('m'),'mdate[d]'=>date('d'))); It works, but isn't there a more simple way to do this ? It seems to be very heavy for just a little change...
