How can I load a Zend Framework plugin?

I have created a plugins directory in the application directory.

Currently I am loading the plugins like so:

protected function _initAccessCheck()
{ 
    include('../application/plugins/AccessCheck.php');
    $fc = 开发者_如何学GoZend_Controller_Front::getInstance();
    $fc->registerPlugin( new Plugin_AccessCheck() );
}

What would I have to do so I would not have to use the include function? Many thanks in advance.

Zend_Loader_Autoloader_Resource allows you to define a mapping between file paths and class names. This allows you to autoload classes whose files are not stored on the include path.

Typically, you would use the subclass Zend_Application_Module_Autoloader which sets up some common mappings for models, forms, etc. In particular, it has an entry for plugins. In Bootstrap, it would be something like this:

protected function _initResourceLoader()
{
    $resourceLoader = new Zend_Application_Module_Autoloader(array(
        'namespace' => 'Application',
        'basePath' => APPLICATION_PATH,
    ));
    return $resourceLoader;
}

Then a class named Application_Plugin_MyPlugin would reside in the file application/plugins/MyPlugin.php.

In your specific circumstance, it looks like you are using an empty namespace. So your's would be:

protected function _initResourceLoader()
{
    $resourceLoader = new Zend_Application_Module_Autoloader(array(
        'namespace' => '',
        'basePath' => APPLICATION_PATH,
    ));

    return $resourceLoader;
}

Then your plugin class Plugin_AccessCheck would reside in the file application/plugins/AccessCheck.php.

Just make sure that the resource loader is created before you instantiate/register your plugins:

protected function _initAccessCheck()
{ 
    $this->booststrap('resourceLoader');
    $fc = Zend_Controller_Front::getInstance();
    $fc->registerPlugin( new Plugin_AccessCheck() );
}

I use application.ini file to enable plugins, in the following way:

For example, for an authentication control plugin I have the following:

class Application_Plugin_AuthCheck extends Zend_Controller_Plugin_Abstract
{
    public function dispatchLoopStartup(Zend_Controller_Request_Abstract $request)
    {
        //check if user is logged in
    }    
}

And then I add it at application.ini

resources.frontController.plugins.authcheck = Application_Plugin_AuthCheck

And it's now registered at application.

Note: I use dispatchLoopStartup but you could use another function as specified here: http://framework.zend.com/manual/en/zend.controller.plugins.html
