Zend_Form is de-coupled from both the MVC and HTTP; the idea is that you
should be able to use it for a variety of purposes, some of which may
have nothing to do with either of those two.
If using the ZF MVC, check to see if the request is a POST:
if ($this->getRequest()->isPost()) {
if ($form->isValid($this->getRequest()->getPost())) {
$values = $form->getValues();
// usually you'll do something with the values and then
// redirect after this...
}
}
$this->view->form = $form;
If you're not using the ZF MVC, check to see what the request method
was:
$method = $_SERVER['REQUEST_METHOD']
if ($method == 'POST') {
// validate now....
}
It's an extra step, but it ensures that you're explicitly checking the
source of your form input.
