way to trigger error

Hi @Sum
Yes you can use flash to display errors. https://docs.phalcon.io/en/latest/reference/flash.html In my project I use it like this.

        $di->set(     
                'flashSession', function ()    
        {    
            return new Phalcon\Flash\Session(array(    
                'error' => 'alert alert-dismissable alert-danger',    
                'success' => 'alert alert-dismissable alert-success',    
                'notice' => 'alert alert-dismissable alert-info',    
            ));    
        }    
        );    

Then you can call

    $this->flash->success("The post was correctly saved!");         

This

    'error' => 'alert alert-dismissable alert-danger',    

is a reference to the css class representing the error. This line of code is an example from bootstrap error.

Flash error not actually what I'm looking for, Maybe something like dispatcher->forward() is closer but I think that's not an error trigger.

Thanks anyway.
