how to get the path and file name of a uploaded file in Zend framework

I have form which allow users to upload a file. From my controller I want to get the path with filename. I am using getFileName() method. But it gives the below error:

Message: Method getFileName does not exist 

Below is my controller action:

public function addAction()
    {
        $form = new Application_Form_Student();
        $form->setAttrib('enctype', 'multipart/form-data');
        $form->submit->setLabel('Add');
        $this->view->form = $form;

        if ($this->getRequest()->isPost()) {
            $formData = $this->getRequest()->getPost();
            if ($form->isValid($formData)) {
                $name = $form->getValue('name');
                $email = $form->getValue('email');
                $photo = $form->getValue('photo');
                $location = $form->getFileName('photo'); 
                $students = new Application_Model_DbTable_Students();
                $students->addStudent($name, $email);

                $this->_helper->redirector('index');
            } else {
                $form->populate($formData);
            }
        }

    }

Check if this works -

public function addAction()
{
    $form = new Application_Form_Student();
    $form->setAttrib('enctype', 'multipart/form-data');
    $form->submit->setLabel('Add');
    $this->view->form = $form;

    if ($this->getRequest()->isPost()) {
        $formData = $this->getRequest()->getPost();
        if ($form->isValid($formData)) {
            $upload = new Zend_File_Transfer_Adapter_Http();
            $upload->setDestination("/uploads/files/");


            try { 
                 $upload->receive();
                 $location = $upload->getFileName('photo');
            }                
            catch(Zend_File_Transfer_Exception $e){
                 $e->getMessage();
            }
        } else {
            $form->populate($formData);
        }
    }

}
