Singular Core provides two optional ways of authorization depending on specific task:

1. Sungular_Core('Auth')->....
2. Predefined auth controller from system module.

login($username, $password, $successRedirectURI = null);

$auth = Singular_Core::_('Auth');
if (!$this->login('username', 'password', '/success')) {
    // handle auth error
}

If authorization is success it's simply redirect to url you have provided in $successRedirectURI.

authenticate($username, $password);

$auth = Singular_Core::_('Auth');
/** @var $result Zend_Auth_Result */
$result = $auth->authenticate('username', 'password');
// Process auth result
switch ($result->getCode()) {
   case Zend_Auth_Result::FAILURE:
	// handle failure
       break;
   case Zend_Auth_Result::FAILURE_CREDENTIAL_INVALID
	// handle invalid credential
       break;

...........

   case Zend_Auth_Result::SUCCESS:
	// success code
       break;
}

For using Auth controller from system module simply add "/login" action parameter to form.

In other words system route "login" forwards to system module, auth controller, login action.

Authorization form example:

    errorMessage)): ?>
    

        errorMessage?>
    
    
    

    

        Username: 
    
    

        Password: 
    
    

        
    

Specify "username" and "password" field. Hidden field "login_type" is not required but if available informs the controller to redirect if authorization is succeeds to appropriate area.

1 (Singular_Core_System_Controller_Auth::LOGIN_TYPE_ADMIN) — "admin_dashboard" route

2 (Singular_Core_System_Controller_Auth::LOGIN_TYPE_USER) — "frontend_home" route

If wasn't set (default value) redirect to "frontend_home" route.
