Hi minglee,
For Zend_Controller_Action_HelperBroker::addPath(string $path, [string
$prefix = 'Zend_Controller_Action_Helper']), the second argument is the
prefix of the helpers.
In your case,
Zend_Controller_Action_HelperBroker::addPath('./application/helpers/',
'MyHelper') means that the helper classes are hiding in
/wwwroot/zf/application/helpers/, and are with prefix 'MyHelper'. For
instance, /wwwroot/zf/application/helpers/SayHello.php
class MyHelper_SayHello extends Zend_Controller_Action_Helper_Abstract {
//...
public function getMessage() {
return 'Hello';
}
//...
}
And we can invoke it as follows
$message = $this->_helper->getHelper('SayHello')->getMessage();
Hope it helps.
