Question

I’m just really starting with the Zend Framework, and currently I’m having a problem with the Zend_Loader_PluginLoader.

I managed to get a module specific plugin working easily enough using the following code:

class Api_Bootstrap extends Zend_Application_Module_Bootstrap
{
    protected function _initPlugins()
    {
        $loader = new Zend_Loader_PluginLoader(array(
            'Api_Plugin' => 'application/modules/api/plugins',
        ));

        $front = Zend_Controller_Front::getInstance();
        $front->registerPlugin(new Api_Plugin_ErrorControllerSelectorPlugin());
    }
}

Edit: The class file is located at application/modules/api/plugins/ErrorControllerSelectorPlugin.php

I then tried to adapt this to get a plugin loaded for the whole application using:

class Bootstrap extends Zend_Application_Bootstrap_Bootstrap
{
    protected function _initAppAutoload()
    {
        $autoloader = new Zend_Application_Module_Autoloader(array(
            'namespace' => 'App',
            'basePath' => dirname(__FILE__),
        ));

        return $autoloader;
    }

    protected function _initPlugins()
    {
        $loader = new Zend_Loader_PluginLoader(array(
            'My_Plugin' => 'application/plugins',
        ));

        $front = Zend_Controller_Front::getInstance();
        $front->registerPlugin(new My_Plugin_ModuleConfigLoaderPlugin());
    }
}

But I’m getting errors:

Fatal error: Class 'My_Plugin_ModuleConfigLoaderPlugin' not found in /var/www/localhost/application/Bootstrap.php on line 22

Edit: The class file is located at application/plugins/ModuleConfigLoaderPlugin.php

So – since the files are where I would expect them to be as far as the prefix/path pairs sent to Zend_Loader_PluginLoader() and the code in both cases are the same, what’s the difference?

How do I get it to recognise my application-level plugins?

Answer 1

If you want the app-level plugin to reside within the namespace My_, you either need to put the My folder out in the library folder or declare the app-level namespace to be My_.

Assuming that you already have other stuff within your top-level app that uses the App_ namespace, then the easiest thing would be the former: move your My folder out into the library.

So, the plugin would reside in:

library/My/Plugins/ModuleConfigLoaderPlugin.php.

Then make sure that your configs/application.ini registers the My_ namespace:

autoloaderNamespaces[] = "My_"

Then the app-level Bootstrap could contain something like:

class Bootstrap extends Zend_Application_Bootstrap_Bootstrap
{
    protected function _initAppAutoload()
    {
        $autoloader = new Zend_Application_Module_Autoloader(array(
            'namespace' => 'App',
            'basePath' => dirname(__FILE__),
        ));

        return $autoloader;
    }

    protected function _initPlugins()
    {
        $front = Zend_Controller_Front::getInstance();
        $front->registerPlugin(new My_Plugin_ModuleConfigLoaderPlugin());
    }
}

Alternatively, since your plugin does not sem to require any params, you could instantiate it via configs/application.ini using:

resources.frontcontroller.plugins[] = "My_Plugin_ModuleConfigLoaderPlugin"
