如何解决错误“Trying to get 属性 of non-object” - Slim 3 Framework PHP

Question

首先，对不起我的英语，其次我的错误是

Notice: Trying to get property of non-object in C:\wamp64\www\projeto\app\OfertasVendor\Middleware\ValidationErrorsMiddleware.php on line 9

ValidationErrorsMiddleware.php的第9行是：

$this->container->view->getEnvironment()->addGlobal('errors',$_SESSION['errors']);

ValidationErrorsMiddleware.php的完整代码为

<?php
namespace OfertasVendor\Middleware;
class ValidationErrorsMiddleware extends Middleware{
    public function __invoke($req, $res, $next){        $this->container->view->getEnvironment()->addGlobal('errors',$_SESSION['errors']);
        //var_dump($_SESSION['errors']);
        //unset($_SESSION['errors']);
        var_dump('teste');
        $res = $next($req, $res);
        return $res;
    }
}

但是，我已经制作了 Middleware.php，我通过了容器，中间件代码：

namespace OfertasVendor\Middleware;
//use OfertasVendor\Controllers\DatabaseController;
class Middleware{
    protected $container;
    public function __contruct($container){
        $this->container = $container;
    }
}

我只需要传递容器->视图，但是，框架不识别容器...

我做了Controller.php

namespace OfertasVendor\Controllers;
abstract class Controller{
    protected $container;
    public function __construct($container){
        $this->container = $container;
    }
    public function __get($key){
        if($this->container->{$key}){
            return $this->container->{$key};
        }
    }
}

我的应用程序 index.php 有中间件

$app->add(new \OfertasVendor\Middleware\ValidationErrorsMiddleware($container));

你能帮帮我吗？

Answer 1

试试 var_dump($this->container); 和 die();

如果那是一个对象，请尝试 var_dump($this->container->view);，然后 die();

基本上，继续 vardump 每一步，直到你到达任何不是对象的地方。 null.

更常见的是 null.
