To use an underscore in the action name you need to:
1)Change the word delimiter used by ZF. The default is a dash. I have the following line of code in my bootstap to do this:
Code:
$frontController = Zend_Controller_Front::getInstance();
$dispatcher = $frontController->getDispatcher();
$dispatcher->setWordDelimiter(array('-', '.', '_'));
2)Camelcase your action method name:
Code:
public function manageUsersAction()
{
// code goes here...
}
3)Place a dash in the name of your view script, in this case manage-users.phtml
