Re: [fw-mvc] Zend_Form_Element will be created twice 7A2-99B

Yet again?

The block messages come from a badly configured mail server that is somehow subscribed to the ZF lists. Mail Wil about this (forward the full block message); he will remove the mail adresses that cause them. Maybe a kick in the butt for that mail server admin is also appropriate, since they seem to subscribe to the lists again and again, only to mess this up.

Sorry if this is a resend I received a block message last time ...

The only thing I can think of is that this part resolves to true when PARENT_ID is passed as a parameter:


        if($this->getDisplayGroup('hiddenFields')) {
            $this->getDisplayGroup('hiddenFields')->addElement($oHidden);    

Without seeing more of your implementation I can't verify that.

Hi,

why the second hidden element will be created twice?

class EventForm extends My_Form {
       
    public function init() {
       
        $this->addHiddenElement('ID');
        $this->addHiddenElement('PARENT_ID');
    }  
}

class My_Form extends Zend_Form {

   protected $_aHiddenDecorators     = array(
        array('ViewHelper')
    );

   protected $_aHiddenGroupDecorators = array(
        'FormElements'
    );

    public function loadDefaultDecorators() {
        $this->setDecorators(array(
            'FormElements',
            'Form',
        ));
    }

    /**
     * builds a hidden element and adds it to the 'hiddenFields' display
group
     * if the display group does not yet exists, it will be created
     */
    public function addHiddenElement($fp_sName, $fp_aOptions = null) {
       
        $oHidden = $this->createElement('hidden', $fp_sName, $fp_aOptions);
        $oHidden->setDecorators($this->_aHiddenDecorators);
        $this->addElement($oHidden);

        if($this->getDisplayGroup('hiddenFields')) {
            $this->getDisplayGroup('hiddenFields')->addElement($oHidden);    
        } else {
            $this->addDisplayGroup(array($oHidden->getName()),
'hiddenFields', array(
                'decorators' => $this->_aHiddenGroupDecorators,
                ));
        }
    }

<form enctype="application/x-www-form-urlencoded" action=".." method="post">

<input type="hidden" name="ID" value="" id="ID">
<input type="hidden" name="PARENT_ID" value="" id="PARENT_ID">
<input type="hidden" name="PARENT_ID" value="" id="PARENT_ID">

</form>

thank you for any help,

Axel
