How to add a view helper directory (zend framework)

I begin with ZF (1.9.7), and I want to use View Helpers from a library shared between all my projects. But I can't find how to add it directory to the helpers path. My herpers works fines when I put them in application's helpers path.

Here is the error, where I find the path to ZF helpers, and path to the applications ones.

object(ArrayObject)#71 (3) {
  ["exception"]=>
  object(Zend_Loader_PluginLoader_Exception)#70 (6) {
    ["message:protected"]=>
    string(151) "Plugin by name 'Voo' was not found in the registry; used paths:
Zend_View_Helper_: Zend/View/Helper/;C:/ZendStd/www/applis/VOO4_PROJECTX/views\helpers/"
    ["string:private"]=>
    string(0) ""
    ["code:protected"]=>
    int(0)
    ["file:protected"]=>
    string(89) "C:\Program Files\Zend\ZendServer\share\ZendFramework\library\Zend\Loader\PluginLoader.php"
    ["line:protected"]=>
    int(401)

It can be done very easily with the built in Zend_Application resource for the view. If you're using ini configs, add a line like this:

resources.view.helperPath.My_View_Helper = "My/View/Helper"

The end of the key is the class name prefix, and the value the path where they reside.

Helper paths are added through Zend_View_Abstract::addHelperPath(). You can call this method directly on an existing View instance.

Helper paths can also be configured in various ways during bootstrap. Check out the ZF manual chapter on Zend_Application to see how to use Bootstrap classes and resources:

There is a problem when using

resources.view.helperPath.App_View_Helper = APPLICATION_PATH "/../library/App/views/helpers"

I can access no view helper in the layout even local helpers in the module. (Plugin by name 'LoggedInAs' was not found in the registry) but still working in views template files.

I put this code "echo Zend_Debug::dump($this)" at the end of layout file and there is a part of output.

        ["_prefixToPaths:protected"] => array(3) {
          ["Zend_View_Helper_"] => array(2) {
            [0] => string(17) "Zend/View/Helper/"
            [1] => string(16) "./views\helpers/"
          }
          ["ZendX_JQuery_View_Helper_"] => array(1) {
            [0] => string(25) "ZendX/JQuery/View/Helper/"
          }
          ["Zend_View_Helper_Navigation_"] => array(1) {
            [0] => string(28) "Zend/View/Helper/Navigation/"
          }
        }

but when using these code in the bootstrap file there is no problem.

    //Initialize and/or retrieve a ViewRenderer object on demand via the helper broker
    $viewRenderer = Zend_Controller_Action_HelperBroker::getStaticHelper('viewRenderer');
    $viewRenderer->initView();
    //add the global helper directory path
    $viewRenderer->view->addHelperPath(APPLICATION_PATH.'/../library/App/views/helpers', 'App_View_Helper');

the output was like below:

            ["_prefixToPaths:protected"] => array(4) {
              ["Zend_View_Helper_"] => array(3) {
                [0] => string(17) "Zend/View/Helper/"
                [1] => string(16) "./views\helpers/"
                [2] => string(86) "D:/zf/application/modules/default/views\helpers/"
              }
              ["App_View_Helper_"] => array(1) {
                [0] => string(85) "D:\zf\application/../library/App/views/helpers/"
              }
              ["ZendX_JQuery_View_Helper_"] => array(1) {
                [0] => string(25) "ZendX/JQuery/View/Helper/"
              }
              ["Zend_View_Helper_Navigation_"] => array(1) {
                [0] => string(28) "Zend/View/Helper/Navigation/"
              }
            }

EDIT: Check out view helper in zend framework for a more detailed take on this issue using rob allen's Loggedinas view helper.

Not only can you do as specified by David Caunt, but you can also do it like this in your bootstrap. Note there is always more than one way to do anything in Zend Framework

Check out http://devzone.zend.com/article/3412

If you have access to the view object, do the following.

<?php    
$view->addHelperPath('My/View/Helper/', 'My_View_Helper'); 
?>

you may need to obtain the view object if you in a front controller plugin

Also Check out this really great set of posts starting here:

I have written short simple tutorial for registering the zend view helpers from a common directory, which can be accessed throughout the application. Please have a look.
