如何访问Laravel Blade文件中对象内部的对象

Question

我有一些数据如下，我正试图在Laravel刀片文件中的对象中获取一个对象，通常它应该可以工作，但在Laraver刀片文件中却无法工作，你能帮我吗？

{

]
}

blade.php

<div class="course-interest">
<ul>
@foreach ($applicant_infos['universities'] as $university)
<li>{{ $university['course']['course_name'] }}</li>
@endforeach
</ul>
</div>

它不起作用。有人能帮助我如何访问laravel blade中对象内部的对象吗？

Answer 1

首先检查$university->course是否为空：

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

Answer 2

如果您正在传递模型对象，则可以访问以下内容

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

你必须像下面的一样将数据传递到降价

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