You may want to take a look at Paddy's series on complex views: * http://blog.astrumfutura.com/archives/281-Complex-Web-Pages-with-the-Zend-Framework.html * http://blog.astrumfutura.com/archives/282-Complex-Views-with-the-Zend-Framework-Part-2-View-Helper-Pattern.html * http://blog.astrumfutura.com/archives/283-Complex-Views-with-the-Zend-Framework-Part-3-Composite-View-Pattern.html * http://blog.astrumfutura.com/archives/285-Complex-Views-with-the-Zend-Framework-Part-4-The-View-Factory.html * http://blog.astrumfutura.com/archives/288-Complex-Views-with-the-Zend-Framework-Part-5-The-Two-Step-View-Pattern.html * http://blog.astrumfutura.com/archives/291-Complex-Views-with-the-Zend-Framework-Part-6-Setting-The-Terminology.html Basically, the action() helper is for those situations where a helper that queries a model is insufficient -- for instance, if you need to verify that the current user has rights to a given resource, or if you want to embed the content of another action within the current view. The idea is that you can then build up pieces of content from other actions. Purists will argue that this should be done in the controller -- for instance, by using the ActionStack helper/plugin to build up content segments that are then injected into the layout. However, different developers have different needs and approaches, and we've simply added the flexibility to do it more than one way. If you don't like the action() helper or the fact that it exists, simply don't use it. -- Matthew Weier O'Phinney PHP Developer | [EMAIL PROTECTED] Zend - The PHP Company | http://www.zend.com/
