Cakephp 3中的Flash消息不起作用 [英] Flash Message in cakephp 3 it doesn't working

问题描述

如果这是一个简单的问题，我是蛋糕新手。

I'm new with cake sorry if this is a simple problem.

当我保存完数据并尝试显示一条有关if的信息时，用户已保存或无法保存，请显示下一个错误：

When i finish to save the data and i try to show a message with information about if the user is saved or could not saved , show me the next error :

错误：在非对象
文件上调用成员函数error（） C：wamp\www\proyecto\src\Controller\AdministradorsController.php
行：76

Error: Call to a member function error() on a non-object File C:\wamp\www\proyecto\src\Controller\AdministradorsController.php Line: 76

AdministradorsController扩展了AppController

AdministradorsController extends AppController

public function add()
{
    $administrador = $this->Administradors->newEntity();
    if ($this->request->is('post')) {

        $this->loadModel('Personas');
        $persona = $this->Personas->newEntity();
        $persona->rut = $this->request->data['Personas']['rut'];
        $persona->sexo = $this->request->data['Personas']['sexo'];
        $persona->nombre = $this->request->data['Personas']['nombre'];
        $persona->apellido_paterno = $this->request->data['Personas']['apellido_paterno'];
        $persona->apellido_materno = $this->request->data['Personas']['apellido_materno'];
        $persona->direccion = $this->request->data['Personas']['direccion'];
        $persona->telefono_fijo = $this->request->data['Personas']['telefono_fijo'];
        $persona->telefono_movil = $this->request->data['Personas']['telefono_movil'];
        $persona->fecha_nacimiento = $this->request->data['Personas']['fecha_nacimiento'];
        $persona->email = $this->request->data['Personas']['email'];
        $persona->comuna_id = $this->request->data['Personas']['comuna_id'];

        if(!$this->Personas->save($persona)){

             $this->Flash->error('The administrador could not be saved. Please, try again.');
        }



        $administrador = $this->Administradors->newEntity();

        $administrador->persona_id = $persona->id;

        if(!$this->Administradors->save($administrador)){

              $this->Flash->error('The administrador could not be saved. Please, try again.');
        }

        $this->loadModel('Users');
        $user = $this->Users->newEntity();
        $user->username = $persona->email;
        $user->password = $this->rand_passwd(6);
        $user->estado = true;
        $user->persona_id = $persona->id;
        $user->role_id = ADMIN;

        if($this->Users->save($user)){

             $this->Flash->success('The administrador has been saved.');

             return $this->redirect(['action' => 'index']);

        }else{
             $this->Flash->error('The administrador could not be saved. Please, try again.');
        }

    }
    $personas = $this->Administradors->Personas->find('list', ['limit' => 200]);
    $this->set(compact('administrador', 'personas'));
    $this->set('_serialize', ['administrador']);

    $this->loadModel('Regions');
    $comunas = $this->Regions->Comunas->find('list', ['limit' => 200]);
    $this->set(compact('comuna', 'comunas'));
    $this->set('_serialize', ['comuna']);
}

数据正在插入数据库，但Flash消息给我一个错误，对不起，我英语和英语不好

The data is inserting into the data base but the Flash message give me a error, sorry for my poor english and thx

推荐答案

如果您要加载 Flash AppController 中的c>组件，问题可能是您的<$ c中具有方法 initialize（） $ c> AdministratorsController ，并且您没有在该方法中调用 parent :: initialize（）; 。它必须正常工作，以便所有在<$ c中初始化的 helpers ， components 等。 $ c> AppController 的 initialize（）方法已转移。

If you are loading the Flash component in your AppController, the issue could be that you have the method initialize() in your AdministratorsController and you are not calling parent::initialize(); in that method. It is a must for it to work so all the helpers, components, etc, that are initialized in AppControllers initialize() method are transferred over.
