       </ul>
</div>

它不工作。谁能帮助我如何访问 laravel 刀片中的对象内部的对象？

【问题讨论】：

标签： php laravel

【解决方案1】：

如果你传递模型对象，你可以像下面这样访问

 @foreach ($applicant_infos->universities as $university)
             <li>{{ $university->course->course_name }}</li>
          @endforeach

已更新。

你必须像下面这样将数据传递给降价

 return $this->markdown('emails.application_email',['app_body'=>$this->app_body,'applicant_infos'=>$this->applicant_infos]);

【讨论】：

<li>{{ $university->course->course_name }}</li>这个方法我试过很多次都不行
请展示你如何在控制器中传递数据
其实是邮寄类
你现在遇到了什么错误
尝试一次 $university->course['course_name ']

【解决方案2】：

先检查$university->course是否为空：

{{ $university->course ? $university->course->course_name : 'Course Not Found' }}
