Question

This is the first time I notice this and it’s surprised me a bit.

I have a zend_form with a simple text element.

$name = new Zend_Form_Element_Text('name');
$name->setLabel('Name');
$this->addElement($name);

The strange thing is that when I submit the form and try to read the value in the form itself (I’m doing some debugging there not in the controller), $name->getValue() doesn’t work but the direct $_POST works.

echo $name->getValue(); //gives blank
echo $_POST['name'];    //gives the right value

Is this normal? How does the form not have its values? I thought it’s better to read them with $field->getValue() than to access the $_POST values directly.

The second question is, to read the value in the form, is there a better way than accessing directly from $_POST?

Answer 1

You need to pass the data explicitly to the form, because ZF has no idea where to get it from:

if ($form->isValid($_POST)) { // access values }

or

if ($form->isValid($request->getPost())) { // access values }
