如何填充()整个Zend_Form减去一个表单元素?

I have a simple content edit form (Zend_Form) that I populate() with an array generated from the Zend_Db_Table_Row_Abstract->toArray() method. It works quite well.

The goal is to not populate one of the form elements with a value.

I'm currently solving this by removing that specific key => value pair from the populating array. I'm curious if there's a way to do that when generating the form element itself.

Say...

$foo = new Zend_Form_Element_Textarea('foo');
$foo->ignoreDefaultValue(true);
$form->addElement($foo);

Any thoughts?

    Nope. When you do $form->validate($data) or $form->populate($data) - internally this is simple

    foreach($formElements as $element) {
        $element->setDefault($newValue);
    }
    

    theare no special internal flags like $form->_populationInProgress = true

    u can achive this easy by extending Zend_Form

    class App_Form extends Zend_Form
    {
        protected $_ignoreDefaults = array();
    
        public function addIgnoredDefaultsElement(Zend_Form_Element $el)
        {
            $this->_ignoreDefaults[$el->getName()] = true;
        }
    
        public function isInIgnoregDefaults($name)
        {
            return (bool)array_key_exists($name, $this->_ignoreDefaults);
        }
    
        public function setDefault($name, $value) 
        {
            if (!$this->isInIgnoregDefaults($name)) {
                parent::setDefault($name, $value);
            }
            return $this;    
        }
    }
