Thread: Help for Integration

Theres a view helper called Action. Take a look at that..
(Might only be available in svn version, not sure.)

Sorry! but i didn't get your point, i'm using the ZF 1.0.3 i guess the latest one. but i'm not very familiar with all the libraries available in there...

Below is a copy of the view helper Action
(this one is taken from svn I think. Ie it might be outdated or otherwise flawed).
View helpers are like widgets/tools you can call from your view scripts. This particular one will call an action and return its output. So in order to include the output from the index action in the news controller you would write:

[PHP]
$this->Action('index', 'news');

//call an action with the parameter id set to 5
$this->Action('index', 'news', null, array('id'=>5));

//call an action in a different module (using mvc)
$this->Action('index', 'news', 'mymodule');
[/PHP]

View helpers should be put in the views/helpers/ dir.

Thank you so much for your sharing... sorry for being such noob here.

Anyway i try to browse on the library on the ZF i didn't find this Action.php under the View helper. or maybe i will add this class file to the library.

Other thing is regarding the sample on how to do it. Can you tell me where will i implement it, is it in the IndexController.php? I hope you can help me..


Thank you very much one again...

Just add the action helper in your zend/view/helpers dir. It should be there by default in the next version (unless they come up with something new to replace it).

You put the call to action() in your view scripts. For instance in index.phtml add
<?php echo $this->action('index','news');?>

I'm happy to help!

It's works now with me... Thank you so much great help... Hopefully you can help me again, if i have other difficulties... Thanks once again

Hi,All
I experienced the problem while using Zend_View_Helper_Action. I want to do the same thing as Weblizzer wanted.I included this Action.php file in Zend/View/Helper/.

I've explained the detail below.

I want to include the output of the XAction to YAction as include(),require() function does in php.But when I make a call to the <?php $this->Action(XAction,"my controller");?> in YAction.phtml and what all I get is my apache gets error message that says "The connection was reset...The connection to the server was reset while the page was loading.".

Can anyone tell me what's going wrong with me...

Thanks in advance...

That particular error is usualy caused by the php session timing out. But in this case I can't really say until you show us more of your code.

From your post I suspect that you are trying to use a view helper as if it was a controller, something that will always fail.

Post the relevant code here and I'll try to give you a better answer.

Hi,
Well,I wrote this in my bootstrap file.

$frontController = Zend_Controller_Front::getInstance();
$frontController->throwExceptions(true);

//module
$frontController->addModuleDirectory(APP_DIR . DIRECTORY_SEPARATOR . 'modules');//APP_DIR . is constant

//Routing
$router = $frontController->getRouter()->addRoute(
'auth',
new Zend_Controller_Router_Route(':module/:controller/:action/*',
array('module' => 'default','controller'=>"index","action"=>"index") )
);

//Use the custom RenderHelper
$viewRenderer = new Custom_Controller_Action_Helper_ViewRenderer();

$view = new Zend_View();

$view->setScriptPath(array(
APP_DIR . DS . 'XXX-Dir'
));

$viewRenderer->setView($view);
Zend_Controller_Action_HelperBroker::addHelper($vi ewRenderer);
====
and in application/modules/default/controllers/indexController.php has
<?php
class indexController extend zend_controller_action
{
public function indexAction()
{
//empty
}
}
corresponding template is located at application/XXX-Dir/index.tpl.php(!=.phtml) has code

<h1>Test</h1>
<?php echo $this->Action('test','test');?>

That calls the TestController.php and respective .tpl.php file followed by the above directory structure.

I've kept the Action.php file in lib/Zend/View/Helper/.

plz tell me what's wrong with here.

Sach
