My application setup with 2 modules admin and default
I test the controller which works fine on modules
but the models doesnt work
I created a model application\modules\admin\models\User.php
<?php
class Admin_Model_User{
}
inside the controller
$user = new Admin_Model_User();
Fatal error: Class 'Admin_Model_User'
not found
Essentially, you need 2 lines in the application.ini file;
resources.frontController.moduleDirectory = APPLICATION_PATH "/modules"
resources.modules[] = ""
Then, for each module, you need a module bootstrap file:
File: myproject/application/modules/{modulename}/Bootstrap.php
<?php
class {Modulename}_Bootstrap extends Zend_Application_Module_Bootstrap
{
}
(Yes, it is an empty class.)
Further details are at http://akrabat.com/zend-framework/bootstrapping-modules-in-zf-1-8/.
Configure an autoloader so that the framework can map your class prefix Admin_Model to the corresponding source path. This is not done automatically.
I suggest reading the part on models of the Zend Framework Quickstart, which explains in detail how to do this.
Are you using an autoloader?
If you do you should change the class name (or path) to reflect the path (or class name)
Models <> Model
You should have
Admin_Model_User in admin/model/user.php
or
Admin_Models_User in admin/models/user.php.

I'm new to Zend Framework. I've been following book "ZendFramework - A Beginners Guide". in the 4th chapter, they start using Doctrine. The thing is that I'd like to use Zend's built-in functionality with database interactions.
I've searched the web and watched couple of tuts. Well I couldn't find the right (for me) solution.
in all tuts, everyone is using standard Zend's structure. I'd like to integrate my Modules. So I have a file structure like this:
application
/modules
/moduleName
/controllers
/models
/views
I have set up the routes in application.ini for controllers and views like this:
; /articles/* route
resources.router.routes.articles.route = /articles
resources.router.routes.articles.defaults.module = content
resources.router.routes.articles.defaults.controller = articles
resources.router.routes.articles.defaults.action = index
Now I tried to load-up my models so I start interacting with the tables in Mysql.
in my controller named ArticlesController.php I created the class Content_ArticlesController and in there I have:
public function indexAction()
{
$model = new Content_ArticlesModel();
$this->view->modelHi = $model->there;
$this->view->hello = 'Hello there';
}
As you might guess Content_ArticlesModel is my class that extends Zend_Db_Table_Abstract class. in there I have a public function modelHi() that I'd like to call from my Controller to pass the data from the model to the view.
Can someone help me do this in the right way? how should I correctly load-up my models for my modules? and maybe you could link some good article on working with database based on some example.
EDIT: Ok, I had this really studip error in my Controller but it's ok. Anyways the problem is that when Zend loads-up my controller it displays: Fatal error: Class 'Content_ArticlesModel' not found in S:\xampp\htdocs\testsite\application\modules\content\controllers\ArticlesController.php on line 12
The issue is my Zend can't locate/doesn't know where to find the models of my module that I'm trying to reach from my controller.
I want to know how should I make Zend see and use my models?
You should make configuration in application.ini file for modeule and view
resources.modules =
resources.view[] =
Also you should make bootstrap file inside your module
class Content_Bootstrap extends Zend_Application_Module_Bootstrap {
}
Also you should ensure that the name of your modulel folder is small letter "content"..
After making these configuration, you will be able to call model inside controller...
Why not just call your public modelHi() method in your controller
Update:
If your module name is 'content' , then your model should be located
application/modules/content/models/ArticlesModel.php
then do the following
public function indexAction()
{
$model = new Content_Model_ArticlesModel(); //name of class
$this->view->modelHi = $model->modelHi();
$this->view->hello = 'Hello there';
}
I am struggling with namespaces in Zend Framework (at least I think it's a namespace issue).
I want to integrate PHPExcel into my Zend project. Relevant file structure is as follows:
/
-library
-ABCD
-PHPExcel
-Zend
-ZendX
-PHPExcel.php
Custom classes work fine, after
Zend_Loader_Autoloader::getInstance()->registerNamespace('ABCD_');
in the bootstrap. Also, those classes are all named ABCD_blahdeblah.
However, doing registerNamespace('PHPExcel_') doesn't help Zend find the appropriate classes. When I try
$sheet = new PHPExcel;
in the controller, I get a "Class not found" error. I am guessing that this is either because classes in PHPExcel aren't named with the namespace prefix, or because the main PHPExcel.php file sits outside of the namespace I've just declared. But the PHPExcel structure demands that it sit in the parent directory of the rest of the class/font/etc files.
Any pointers would be greatly appreciated.
Thanks in advance.
Create an autoloader for PHPExcel and add it to the Zend autoloader stack.
In library/My/Loader/Autoloader/PHPExcel.php:
class My_Loader_Autoloader_PHPExcel implements Zend_Loader_Autoloader_Interface
{
public function autoload($class)
{
if ('PHPExcel' != $class){
return false;
}
require_once 'PHPExcel.php';
return $class;
}
}
And in application/configs/application.ini:
autoloadernamespaces[] = "My_"
Then, in application/Bootstrap.php:
protected function _initAutoloading()
{
$autoloader = Zend_Loader_Autoloader::getInstance();
$autoloader->pushAutoloader(new My_Loader_Autoloader_PHPExcel());
}
Then you should be able to instantiate PHPExcel - say, in a controller - with a simple:
$excel = new PHPExcel();
The only sticky part is all of this is how PHPExcel handles loading all its dependencies within its own folder. If that is done intelligently - either with calls like require_once basename(__FILE__) . '/someFile.php' or with its own autoloader that somehow doesn't get in the way of the Zend autoloader - then all should be cool. #famouslastwords
Nowadays composer is a frequently used tool that wasn't so popular back in 2012. Even older projects built in ZF1 can make use of composer and its autoloader.
How to get all your libraries to work without having to add custom autoloaders to your application.ini each time?
Make use of composer's autoloader
First, start with setting up composer.json. Once created, run composer install to gather all required packages and create composer's autoloader.
Now, let's update your project's public/index.php. From now on all requirements that are loaded via composer will be autoloaded.
<?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') : 'development'));
// Include composer autoloader
require_once __DIR__ . '/../vendor/autoload.php';
/** Zend_Application */
require_once 'Zend/Application.php';
// Create application, bootstrap, and run
$application = new Zend_Application(
APPLICATION_ENV,
array( 'config' => APPLICATION_PATH . '/configs/application.ini' )
);
$application->bootstrap();
$application->run();
Try modifying the PHPExcel autoloader:
Add
if (function_exists('__autoload')) {
spl_autoload_register('__autoload');
}
as the first two lines of the Register() method in /Classes/PHPExcel/Autoloader.php, immediately before
return spl_autoload_register(array('PHPExcel_Autoloader', 'Load'));
I've had a similar problem with both an exel-librare (phpxls) and a pdf-library (fpdf) and after some different tries I just settled with including the required file from the library manually and go from there. Booth phpxls and fdpd can then handle everything else without interfering with the zend autoloader methods.
A psudo_code example would look like this, where I return a object of the desired class and then can continue to work with that. You could offcourse choose to include things in the constructor and build from that.
<?php
class exelClass{
public function exelFunction(){
require_once 'required_file.php';
$exelObject = new exelObject();
return $exelObject->Output();
}
}
?>
This solution might not be that elegant, but I found that it was the easiest way to enable different types of libraries to co-exist without differnet autoloaders or magic functions interfearing with each other.
How can I make every module have it's own layouts directory?
I.e. when I don't have any modules my layout entry in config file looks like this:
resources.layout.layoutPath = APPLICATION_PATH "/layouts"
I try entering i.e.
; Layout directory for admin module
admin.resources.layout.layoutPath = APPLICATION_PATH "/modules/admin/layouts"
Where admin is module name; but it doesn't work. For some strange reason ZF looks for module layouts in /module/admin/views/scripts directory.
I also have a separate module.ini config file for every module as per this tutorial, alas layout path there gets ignored as well. Also I've been trying to follow this modules layout tutorial but it didn't work, I guess due to differences in ZF versions (tutorial is rather old). So I don't know what else to do
Using plugin from the tutorial you are talked about:
class My_Controller_Plugin_RequestedModuleLayoutLoader extends Zend_Controller_Plugin_Abstract {
public function preDispatch(Zend_Controller_Request_Abstract $request) {
$config = Zend_Controller_Front::getInstance()->getParam('bootstrap')->getOptions();
$moduleName = $request->getModuleName();
if (isset($config[$moduleName]['resources']['layout'])) {
Zend_Layout::startMvc($config[$moduleName]['resources']['layout']);
}
}
}
application.ini
resources.frontController.plugins.layoutloader = My_Controller_Plugin_RequestedModuleLayoutLoader
module.ini:
resources.layout.layout = "Admin"
resources.layout.layoutPath = APPLICATION_PATH "/modules/admin/layouts/scripts"
Working fine.
A slightly alternate method to Ololo recommendation (which is a great way to do it)..
class YourApp_Controller_Plugin_Modulelayout extends Zend_Controller_Plugin_Abstract
{
public function routeShutdown(Zend_Controller_Request_Abstract $request)
{
$module = $request->getModuleName();
if ($module != 'default')
{
if (file_exists(APPLICATION_PATH . '/layouts/' . $module . '.html')) {
Zend_Layout::getMvcInstance()->setLayout($module);
}
}
}
}
Place this controller plugin in /library/YourApp/Controller/Plugin/Modulelayout.php
Then save your module layouts as the module name in your layouts folder (E.g., /layout/admin.phtml). If it does not find a layout for that module, it will default back to layout.phtml or whatever you originally set it to.
Have a look at this gist - https://gist.github.com/891384
This uses a combination of
Action helper to inspect the requested module and given a matching configuration, change the layout's layout and layoutPath properties in the preDispatch hook
Application resource plugin to capture module layout options, inject them into the above helper and add it to the helper broker
Happened to me too I got around it by using this line in my controller (I created a init function)
Zend_Layout::startMvc(array('layoutPath' => APPLICATION_PATH . '/modules/admin/layouts'));
As of Zend Framework 1.12 (Haven't tested it on previous releases):
Create your modules
Initialize the layout in your prefered fashion. For example in application.ini as zend tools does it:
resources.layout.layoutPath = APPLICATION_PATH "/layouts/scripts"
Create a layout inside each module with the default layout name inside the modules path to "views/scripts/" for example "application/modules/default/views/scripts/layout.phtml"
Don't forget to create one for the default module as it will be your fallback layout!
DO NOT create the default layout inside /application/layouts/scripts or this won't work
You are ready to run!
When Zend_Layout doesn't find the default layut it will look into the modules folders for it.
If you need some extra tweaking you may create a plugin and assign it to the layout object itself. For example, inside application.ini:
resources.layout.pluginClass = "MyLibrary_Controller_Plugin_Layout"
...or in the Bootstrap:
Zend_Layout::getMvcInstance()->setPluginClass("MyLibrary_Controller_Plugin_Layout");
Cheers!
I am learning how to use Zend framework and realise that the action helper is something that would be useful.
I have set up a default installation of Zend on my machine, but I dont know where the helper file needs to go, what I need to put in the bootstrap file and how I use it. Can anyone point me in the right direction please - the ZF user guide is not to clear to me.
Thanks

Two thoughts for where to place your custom action-helpers:
In a separate, custom library
In the folder application/controllers/helpers
These ideas are not exclusive. Functionality that is general enough to work in multiple projects should probably be pulled into a separate library. But for functionality that is application-specific, there is an argument that it could be somewhere in the application folder.
#Jurian has already described the "separate-library" approach. For app-specific helpers, you can do as follows:
For a helper called myHelper, create a class Application_Controller_Helper_MyHelper in the file application/controllers/helpers/MyHelper.php. In Bootstrap, you have something like:
protected function _initAutoload()
{
$autoloader = new Zend_Application_Module_Autoloader(array(
'namespace' => 'Application',
'basePath' => APPLICATION_PATH,
));
Zend_Controller_Action_HelperBroker::addPath(
APPLICATION_PATH . '/controllers/helpers',
'Application_Controller_Helper_');
return $autoloader;
}
Then your helper can be invoked in a controller by using:
$this->_helper->myHelper;
As you can see, this presumes you are using appNamespace 'Application'. If not, you can (must!) modify your class names to accommodate your circumstance.
Cheers!
You can place action helpers in your own library. Besides library/Zend where all the Zend stuff is around, you can create a library/MyLibrary folder (MyLibrary is arbitrary chosen) and put the action helpers there.
A good place is the library/MyLibrary/Controller/Action/Helper folder you need to create and place your action helper there (i.e. Navigation.php). In this file, create the class MyLibrary_Controller_Action_Helper_Navigation.
The next step is to add the action helper to the HelperBroker of the Zend Framework during bootstrap. Therefore, create a new method in your Bootstrap.php file and add this function:
protected function _initActionHelpers ()
{
Zend_Controller_Action_HelperBroker::addHelper(
new MyLibrary_Controller_Action_Helper_Navigation()
);
}
One last remark is you need to configure the use of this library by adding this rule to your application.ini:
autoLoaderNameSpaces[] = "MyLibrary_"
You can do this through your application.ini file like so
resources.view[] =
resources.view.helperPath.Default_View_Helper_ = APPLICATION_PATH "/views/helpers/"
Then in your views/helpers path you can create a file like Time.php. This file would contain the following code:
<?php
class Default_View_Helper_Time extends Zend_View_Helper_Abstract
{
public function time()
{
$date = new Zend_Date();
return $date->get(Zend_Date::TIME_MEDIUM);
}
}
?>
To use this in your view scripts you would use
<?=$this->time()?>
Which would display the current time using your new View_Helper
You can avoid having to register your action helper namespace and path within the Bootstrap.php by declaring them in the application.ini instead like so:
resources.frontController.actionHelperPaths.My_Controller_Action_Helper = APPLICATION_PATH "/controllers/helpers"
Simply replace My_Controller_Action_Helper with your desired namespace, and modify the helpers directory path accordingly.
The helper can be initialized the same way:
$this->_helper->myHelper;
As mentioned by the docs, registering the prefix or path of the helpers is usually preferred because helpers would not be initialized until they are called like in the snippet above.
Of course, instantiating and passing helpers to the broker is a bit
time and resource intensive, so two methods exists to automate things
slightly: addPrefix() and addPath().
http://framework.zend.com/manual/1.12/en/zend.loader.pluginloader.html
Adding the config entry to the application.ini follows the same suggested pattern.
Trying to make a controller helper to have similar functionality in some controllers using the preDispatch method.
Error:
Fatal error: Class 'Helper_Action_Test' not found in /var/www/zend.dev/application/Bootstrap.php on line 9`
Application layout
/Application
/Helpers
**/Actions** this is where i will save the classes
/Views
/modules
/configs
/layouts
/Bootstrap.php
In the Bootstrap I have added:
protected function _initActionHelpers(){
Zend_Controller_Action_HelperBroker::addHelper(new Helper_Action_Test());
}
In the helper file I have:
class Helper_Action_Test extends Zend_Controller_Action_Helper_Abstract{
public function preDispatch() {
echo 'Test';
}
}
When I do this in the bootstap it works, it might have to do with the include or how I am trying to instantiate the new class with the addHelper();
include(APPLICATION_PATH.'/helpers/action/Test.php');
Zend_Controller_Action_HelperBroker::addHelper(new Test());
Any ideas?
try this one:
// Action Helpers
Zend_Controller_Action_HelperBroker::addPath(
APPLICATION_PATH .'/controllers/helpers');
$hooks = Zend_Controller_Action_HelperBroker::getStaticHelper('Quote');
Zend_Controller_Action_HelperBroker::addHelper($hooks);
You have to include the helper file bootstrap file I think.
Or I think you want to: require_once() it
By adding the following lines in your config file you will be able to achieve what you want
; Include path
includePaths.library = APPLICATION_PATH "/../library"
; Autoloader Namespace
autoloaderNamespaces[] = 'Helper_'
More info in the official ZF doc Autoloader
To solve your problem, make sure the _initAutoload() on your bootstrap is the first method and also make sure you have added the prefix path:
Zend_Controller_Action_HelperBroker::addPrefix('Helper_Action');
You can aslo provide the path to the classes if they are not on the include_path:
Zend_Controller_Action_HelperBroker::addPath(APPLICATION_PATH . '/helper/action/', 'Helper_Action');
