Someone was recently asking on ZFTalk about how to use a different layout for each module in your application. Since this is a problem I’ve dealt with in the past and planned on adding to the Galahad FE, I thought I’d quickly write up a tutorial on how to do it:

First, download the Plugin

Put the following class in a library/Galahad/Controller/Plugin/Modularlayout.php file (you’ll probably have to create all those directories and the file).

<?php

*/
class Galahad_Controller_Plugin_Modularlayout extends Zend_Controller_Plugin_Abstract
{
     public function routeShutdown(Zend_Controller_Request_Abstract $request)
     {
          Zend_Layout::getMvcInstance()->setLayout($request->getModuleName());
     }
}

Next, add the Galahad namespace

Update your Bootstrap.php file’s autoloader initialization method (if you don’t have one, add one):

protected function _initAutoloaders()
{
	$this->getApplication()->setAutoloaderNamespaces(array('Galahad_'));
	return $this;
}

Please note: You might need to have other namespaces in there, like My_ or App_ or Default_.

Next, add the Plugin

Update your Bootstrap.php file’s plugin initialization method (if you don’t have one, add one):

protected function _initPlugins()
{
	$this->bootstrap('autoloaders');
	$this->bootstrap('frontController');

	$plugin = new Galahad_Controller_Plugin_Modularlayout();
        $this->frontController->registerPlugin($plugin);
}

And you’re set!

Just make sure you have a layout file in your layouts directory for each module (modulename.phtml).
