Question

在我的ProjectController类中，我有两个方法：

private function checkUserProject($project){
    if(!(Auth::check())) return false;
    elseif($project->user_id != Auth::user()->id) return false;
    else return true;
}

public function getProject($project){
    $project = Project::where('unique_id',$project)->first();
    if(!$this->checkUserProject($project)) return Redirect::route('');
    return $this->process($project);
}

我收到了一个“尝试获取非对象属性”的错误。在checkUserProject()方法中。

我有return $project，它完全返回$project。

修改

错误消息：

ErrorException (E_NOTICE)  
Trying to get property of non-object

<?php
class Print3dController extends \BaseController
{
private function checkUserProject($project){
    if(!(Auth::check())) return false;
    elseif($project->user_id != Auth::user()->id) return false;
    else return true;
}

dd($project)的输出是：

我认为$project可能没有user_id变量，因此您必须首先为empty()添加isset()或$project->user_id，然后进行验证。
