Thread: Layout Changing according to Module change

I would like to develop Module based application.
My directory structure

/project
---/application
------/configs
---------application.ini
------/layouts
---------/scripts
admin.phtml
usermanagement.phtml
------/modules
---------/admin
------------/controllers
IndexController.php
------------/models
------------/views
---------------/filters
---------------/helpers
---------------/scripts
/index
index.phtml
---------/usermanagement
------------/controllers
---------------UserController.php
------------/models
------------/views
---------------/filters
---------------/helpers
---------------/scripts
------------------/user
login.phtml
---------Bootstrap.php
---/library
------/Zend
------/ZendX
------/Tp
---------/Controller
------------/Action
---------------/Helper
------------------LayoutLoader.php
---/public
------/img
------/css
------/js
------.htaccess
------.index.php

Here is my application.ini file

[production]

; Config Errors
phpSettings.display_startup_errors = 0
phpSettings.display_errors = 0

; Config Timezone
phpSettings.date.timezone = "Europe/London"

; Config Include Paths
includePaths.library = APPLICATION_ROOT "/library"

; Config Bootstrap
bootstrap.path = APPLICATION_PATH "/bootstrap.php"
bootstrap.class = "Bootstrap"

; Config Module
resources.modules[] = ""
resources.frontController.moduleDirectory = APPLICATION_PATH "/modules"
resources.frontController.moduleControllerDirector yName = "controllers"

resources.frontController.defaultModule = "usermanagement"
resources.frontController.defaultControllerName = "user"
resources.frontController.defaultAction = "login"

; Config Layout
resources.layout.layoutPath = APPLICATION_PATH "/layouts/scripts"
resources.layout.layout = usermanagement

admin.resources.layout.layout = admin
usermanagement.resources.layout.layout = hospital

; Config View
resources.view.encoding = "UTF-8"
resources.view.doctype = "XHTML1_STRICT"
resources.view.contentType = "text/html;charset=utf-8"
resources.view.headTitle = "Test Project"
resources.view.setSeparator = " - "

; Config Namespaces
autoloadingNamespaces.tp= "Tp_"

; Config Database
resources.db.adapter = "PDO_Mysql"
resources.db.params.hostname = "localhost"
resources.db.params.username = "root"
resources.db.params.password = "testpassword"
resources.db.params.dbname = "test_project"

[developmentroduction]

; Config Errors
phpSettings.display_startup_errors = 1
phpSettings.display_errors = 1

; Config Database
resources.db.params.dbname = "test_project_dev"

And here is my Bootstrap.php file

<?php
/*
* To change this template, choose Tools | Templates
* and open the template in the editor.
*/

/**
* Description of Bootstrap
*
* @author Programmer1
*/
class Bootstrap extends Zend_Application_Bootstrap_Bootstrap
{
protected function _initAutoload()
{
$moduleLoader = new Zend_Application_Module_Autoloader(array(
'namespace' => '',
'basepath' => APPLICATION_PATH . '/modules/usermanagement'
));
}

protected function _initView()
{
$options = $this->getOptions();

// Create View Object
if (isset($options['resources']['view'])) {
$view = new Zend_View($options['resources']['view']);
} else {
$view = new Zend_View;
}

// Set Doctype
if (isset($options['resources']['view']['doctype'])) {
$view->doctype($options['resources']['view']['doctype']);
}

// Set Content Type
if (isset($options['resources']['view']['contentType'])) {
$view->headMeta()->appendHttpEquiv('Content-Type',
$options['resources']['view']['contentType']);
}

// Set Head Title
if (isset($options['resources']['view']['headTitle'])) {
$view->headTitle($options['resources']['view']['headTitle']);
}

// Set Separator
if (isset($options['resources']['view']['setSeparator'])) {
$view->headTitle()->setSeparator($options['resources']['view']['setSeparator']);
}

$view->addHelperPath('ZendX/JQuery/View/Helper/', 'ZendX_JQuery_View_Helper');

$viewRenderer = Zend_Controller_Action_HelperBroker::getStaticHelp er(
'ViewRenderer'
);
$viewRenderer->setView($view);

Zend_Controller_Action_HelperBroker::addHelper(new Tp_Controller_Action_Helper_LayoutLoader());
}
}
?>

Here is LayoutLoader.php file

<?php

class Tp_Controller_Action_Helper_LayoutLoader extends Zend_Controller_Action_Helper_Abstract
{

public function preDispatch()
{
$bootstrap = $this->getActionController()->getInvokeArg('bootstrap');
$config = $bootstrap->getOptions();
$module = $this->getRequest()->getModuleName();
if (isset($config[$module]['resources']['layout']['layout'])) {
$layoutScript = $config[$module]['resources']['layout']['layout'];
$this->getActionController()
->getHelper('layout')
->setLayout($layoutScript);
}
}
}

Question 1:

Usermanagement is the default Module and login is the default Action. Different Module has different layout and whenever user switch from one module to another, the application automatically load the module's layout. But my existing application is not working like that. What are the additional tasks i have to do?

Question 2:

If application needs to switch different layout within same module and same controller but different action, what are the additional tasks i have to do?
