Zend Framework _forward不起作用

I am trying to use $this->_forward() to go to another action in the same controller but it is not working. My code is...

class IndexController extends Zend_Controller_Action
{
    public function indexAction()
    {
        $this->view->bodyCopy = "<p>Please select a file to upload.</p>";

        $form = new forms_UploadForm();

        if ($this->_request->isPost()) {
            $formData = $this->_request->getPost();
            if ($form->isValid($formData)) {
                $this->_forward('displayFileContent');
            } else {
                $form->populate($formData);
            }
        } else {
            $this->view->form = $form;
        }

    }

    public function displayFileContentAction()
    {
        die("In displayFileContentAction");
    }
}

but I am not getting my die message. I get an error saying 'Page not found'.

Any help would be greatly appreciated as I have been having real trouble with this.

Why are you forwarding ? just execute the code, replace

$this->_forward('displayFileContent');

with

return $this->displayFileContentAction();

Why dont you try

     $this->_redirect('/Controller/displayFileContent');

//Your action 

    public function displayFileContentAction(){
    $this->_helper->viewRenderer->setNoRender(true);
    $this->_helper->layout->disableLayout();
    die("In displayFileContentAction");


    }

When you call the $this->_forward('displayFileContent') you go through the routing stack of Zend Framework. The routing then search for the displayfilecontent action which doesn't exists (url are case-insensitive).

To reach that URL you will need to forward to $this->_forward('display-file-content'), using dashes instead of camel case.

You will then need to create a view file named display-file-content.phtml or to disable view rendering for this action

Your code should be:

class IndexController extends Zend_Controller_Action
{
    public function indexAction()
    {
        $this->view->bodyCopy = "<p>Please select a file to upload.</p>";

        $form = new forms_UploadForm();

        if ($this->_request->isPost()) {
            $formData = $this->_request->getPost();
            if ($form->isValid($formData)) {
                return $this->_forward('display-file-content');
            } else {
                $form->populate($formData);
            }
        } else {
            $this->view->form = $form;
        }

    }

    public function displayFileContentAction()
    {
        die("In displayFileContentAction");
    }
}

Notes:

• To forward to the Action you requested you must forward to $this->_forward('display-file-content'). Use dashes instead of camel cased.
• You should add a return to $this->_forward('display-file-content') or your current Action will continue to execute before forwarding to the other Action.
• you must create a view for the other Action and call it display-file-content.phtml or just disable the view for this Action using $this->_helper->viewRenderer->setNoRender(true); $this->_helper->layout->disableLayout();.
