Question

I have a user define class inside my zend application(as default)

application/library/Custom_/Custom_Test.php

I want to use it in getvalueAction() in side indexController.php

I have tried included following line in application.ini at [production]

autoloaderNamespaces.custom = "Custom_"

I don’t want to use simple include function and I can’t instantiate it inside getvalueAction(). How to do that ?

• using netbeans
• ubuntu 11.10
• I’m new to zend

Thank you.

PS: I will show my code bellow for the sake of clarity

indexController.php

<?php

class IndexController extends Zend_Controller_Action
{

    public function init()
    {}

    public function indexAction()
    {}

    public function getvalueAction() {
        $request = $this->getRequest();
        $numb = $request->getParam('numb');

        $result = Test::testFunction($numb);
        $this->view->assign('result',$result);
    }

    public function inputAction() {
        $this->view->assign('action','getvalue');
    }
}

inside the input.phtml

  <form name="enterNumber" method="post" action="<?php echo $this->escape($this->action)?>" >

      input a number :
      <input type="text" name="numb"/> <br/>
      <input type="submit" value="Submit" />


  </form>

inside the getvalue.phtml

  <h1><?php echo "Final value id " . $this->escape($this->result); ?></h1>

index.php

<?php

// Define path to application directory
defined('APPLICATION_PATH')
    || define('APPLICATION_PATH', realpath(dirname(__FILE__) . '/../application'));

// Define application environment
defined('APPLICATION_ENV')
    || define('APPLICATION_ENV', (getenv('APPLICATION_ENV') ? getenv('APPLICATION_ENV') : 'production'));

// Ensure library/ is on include_path
set_include_path(implode(PATH_SEPARATOR, array(
    realpath(APPLICATION_PATH . '/../library'),
    get_include_path(),
)));

/** Zend_Application */
require_once 'Zend/Application.php';

// Create application, bootstrap, and run
$application = new Zend_Application(
    APPLICATION_ENV,
    APPLICATION_PATH . '/configs/application.ini'
);
$application->bootstrap()
            ->run();

application.ini

[production]
phpSettings.display_startup_errors = 0
phpSettings.display_errors = 0
includePaths.library = APPLICATION_PATH "/../library"
bootstrap.path = APPLICATION_PATH "/Bootstrap.php"
bootstrap.class = "Bootstrap"
appnamespace = "Application"
resources.frontController.controllerDirectory = APPLICATION_PATH "/controllers"
resources.frontController.params.displayExceptions = 0

[staging : production]

[testing : production]
phpSettings.display_startup_errors = 1
phpSettings.display_errors = 1

[development : production]
phpSettings.display_startup_errors = 1
phpSettings.display_errors = 1
resources.frontController.params.displayExceptions = 1

Custom_Test.php

<?php

    class CustomTest{

        function testFunction($a) {

            return $a*2;
        }
    }

?>

Action helper is what you need.

since you said

I want to use it in getvalueAction() in side indexController.php

According to official Zend Framework’s Website

Action Helpers allow developers to inject runtime and/or on-demand
functionality into any Action Controllers that extend
Zend_Controller_Action. Action Helpers aim to minimize the necessity
to extend the abstract Action Controller in order to inject common
Action Controller functionality.

i assume you want to use action helper, since action helper was specifically designed for this purpose.

Step 1.
You need to tell the helper broker where your action helpers are, i usually do that in my application.ini file, but you can do that in your frontController or Bootstrap file too.

#if you are using application.ini, in your application.ini add the following
resources.frontController.actionHelperPaths.Custom_Action_Helper = APPLICATION_PATH "/../library/Custom/helpers"

Step 2:
Creating the Action Helper class, you have to make sure the class extends Zend_Controller_Action_Helper_Abstract and place the file in defined helper directory in your case it is Library/Custom/helpers

and create the action helper like this

class Custom_Action_Helper_Test extends Zend_Action_Helper_Abstract
{
    public function random()
    {
        return 'foo';
    }
}

now helpers are ready to be used inside any controller. it may be called by using following syntax.

echo $this->_helper->Test->random();

hope this helps you.
