Question

I’m trying to figure out what is going on below:

public function serviceAction(){
$config = Zend_Registry::get('config');

$client = new Zend_Http_Client();
$client->setAuth($config['api']['username'],$config['api']['password']);

$service = new Krixton_JsonRpc_Client($config['api']['endpoint'], $client);

switch($this->_getParam('task'))
{
   case 'test':
       if(!this->getParam('newsletter_id')){
            $this->_helper->json(array('sent'=>false,'error'=>'Newsletter ID is invalid, must be numeric'));
            return;
       }

       $request = $service->call('newsletter.send', array($this->_getParam('newsletter_id'),false));
       $this->_helper->json($request->result));
   break;

}

}

What I’m trying to find out is how does

`Zend_Registry::get('config')`, $client->setAuth and $service->call`

works?

I understand _getParam('task') is a method to get get or post variables but not sure about the others. I had a look through some Zend documentations but if someone could help me out that would be appreciated!

Answer 1

Two things are happening there, the first one is Zend_Registry. get()allow you to get a value previously registered in the registry via Zend_Registry::set('key', $value). Usually, ‘config’ is your application configuration, which is the application.ini file.

basically, you would register config using this bootstrap method:

protected function _initConfig()
{
    $config = new Zend_Config($this->getOptions());
    Zend_Registry::set('config', $config);
    return $config;
}

The second ones are nothing else than methods of Zend_Http_Client. setAuth()is used to set a basic HTTP authentification, and call()is an internal method of your object Krixton_JsonRpc_Client.

If you’re trying to understand deep down how does these methods work, you should read the man first (especially Zend_registry and Zend_Http_Client pages) and then read carefully the source code.
