Zend Framework Application Progress

Today I learned from Zend Framework.

Redirecting visitors to their intended URI after login

LoginForm.php

  ...
  // Grabs the requested URI from the server and stores it in a hidden field
  $this->addElement('hidden', 'referrer', array('value' => $_SERVER['REQUEST_URI']));
  ...

Then after you complete authentication, send them to the referring URI

  if($form->getValue('referrer'))
      $this->_redirect($form->getValue('referrer'));
  $this->_redirect('index/index');

Throwing an error message

This one is easy. You want to throw an error message with some meaning.

  throw new Zend_Exception('This is the error message');

Saving data in Zend_Session

You want to save some data in a session variable so you can access it other places in application. So in the Bootstrap.php file you would place

  Zend_Session::start();

To set the variable you would use

  $ns = new Zend_Session_Namespace('hello');
  $ns->domain = "Hello World";

To retrieve this fun filled variable.

  $ns = new Zend_Session_Namespace('hello');
  print $ns->domain;
