Re: QFC - how do you validate and then buildForm() ?

This is my first post to this list (I think). I have a custom QFC action whose effect is to alter the way the form is built. I do not want to process the action unless the form is valid though, but this requires me to build the Page first using Page::buildForm(). This poses a dilemma, as no matter what I try I can not seem to rebuild the Page differently to the way it was first built. Does anyone have a workaround? Much appreciated.

I suggest making *two* different pages, triggered by this particular action. IIRC, there is an example for this in QFC. Thanks. That's a good suggestion. My QuickForm has fields dynamically added to or removed from it as a result of a custom action handler, so that would not work (unless I have misunderstood). Here's the solution I came up with as a method on a class extending HTML_QuickForm_Page:

----%<---- function rebuildForm() {

       if ($this->isFormBuilt() ) {
           $this->_formBuilt = false;
           $pageName = $this->getAttribute('id');

           // get the automagical form elements
           $trackSubmitElem =& $this->_elements[$this->_elementIndex["_qf__{$pageName}"] ];
           $defaultElem     =& $this->_elements[$this->_elementIndex["_qf_default"] ];

           $this->_elements     = array();
           $this->_elementIndex = array();
           $this->addElement($trackSubmitElem);
           $this->addElement($defaultElem);
       }
       return $this->buildForm();

} ----%<---- I've found this does the trick nicely.
