title: Why no Zend_Layout helper or codebehind? And best way to
body: <p>I was just wondering why no code-behind or helpers were made to work with layouts? I have stuff I want to display in my layouts without having to set it up in a placeholder for every single controller.</p>
  
  <p>I was also wanted to know what is the best way to persist a display-once "success-message" across many pages. For example, a user fills out a form and when it is submitted correctly they are redirected to another page. I want the user to see a success message on that other page. Is there some sort of provision in Zend Framework that makes this easier?</p>
