Padraic Brady has continued his series about making a sample blogging application with the Zend Framework in a new blog post, part six - a focus on Zend_Form and Zend_Auth.

In the previous entry, we created a new Administration Module to hold blog management functionality, added a Module specific layout for it, and discussed the upcoming need to ensure this is only accessible by authorised Authors. In this entry I'll unravel some of Zend_Form's mysteries in adding a login form, before using Zend_Auth to implement authentication for authors.

He includes the code (controller and view) to add the login form as a part of the Author functionality and, using a few decorators to help him build the form how he likes it, extends the Zend_Form component to make his form with username, password and submit elements. He throws in some validation and a bit of error checking to finish it off.

The Zend Developer Zone has posted a new look something recently added to the Zend Framework - support in the Zend_Auth component for OpenId connections.

Since there have been numerous tutorials written regarding Zend_Auth, I won't attempt to make a full tutorial on it. If you are curious, google around, you'll find them. Today though, I'd like to show you a cool new piece that has been added to Auth in Zend Framework 1.5, the new Zend_Auth_Adapter_OpenId.

Cal explains what the OpenID system is all about before getting into the code that uses it. He suggests MyOpenID as a provider to register at and includes the code to make a request to them to authenticate a username/password combo. The actual authentication check is only about three or four lines of code.
