假設(shè)你已經(jīng)注冊(cè)"falsh"服務(wù)：php/**1.RegistertheflashservicewithcustomCSSclasses*/$di->set('flash',function(){$flash=new\Phalcon\Flash\Direct(array('error'=>'alertalert-dangercalloutcallout-danger','success'=>'alertalert-success','notice'=>'alertalert-info','warning'=>'alertalert-warning'));return$flash;});以\Phalcon\Mvc\Model為例,在controller里面：phpif($Article->save()){$this->flash->success($Article->title.'hasbeenupdated');}else{foreach($Article->getMessages()as$message){$this->flashSession->error($message);}return$this->response->redirect($paginateUrl);$this->view->disable();}當(dāng)然，你也可以自定義驗(yàn)證信息：phppublicfunctionvalidation(){$this->validate(newUniqueness(array('field'=>'slug','message'=>'Theslugalreadyexistsinotherarticles,pleasemodifythearticletitle')));if($this->validationHasFailed()==true){returnfalse;}}

如果是workingwithmodels則$robot=newRobots();$robot->type="mechanical";$robot->name="AstroBoy";$robot->year=1952;if($robot->save()==false){echo"Umh,Wecan'tstorerobotsrightnow:\n";foreach($robot->getMessages()as$message){echo$message,"\n";}}else{echo"Great,anewrobotwassavedsuccessfully!";}如果是phql則$phql="INSERTINTOCarsVALUES(NULL,'NissanVersa',7,9999.00,2012,'Sedan')";$result=$manager->executeQuery($phql);if($result->success()==false){foreach($result->getMessages()as$message){echo$message->getMessage();}}
