laravel - laravel 帖子的 index.php 中 undefined variable

Question

我的错误: undefined variable :asd(查看:C:\xampp\htdocs\kproject\resources\views\posts\index.blade.php)

Controller :

use App\post;
public function index()
    {
          $asd = post::all();
        return view ('posts.index')->with('post','$asd');
    }

Index.blade.php

@extends('layout.app')


@section('content')
    <h1> Peoples</h1>
    <hr>
   @if(count($asd)>0)
    @foreach($asd as $post)

<p> {{$post->username}}  </p>

    @endforeach

@else
<p> No Posts  </p>
   @endif



@endsection

我不知道为什么会出现此错误，请提供帮助!

Answer 1

您正在传递 $asd 变量来查看...但名称不同。 View 中的名称将为 $post。

->with('post', $asd) ...传递 $asd 变量来查看并将其分配给 $post

将index.blade.php更改为:

@extends('layout.app')

@section('content')
<h1> Peoples</h1>
<hr>
@if(count($post)>0)
    @foreach($post as $p)

    <p> {{$p->username}}  </p>

@endforeach

@else
    <p> No Posts  </p>
@endif
@endsection
