我是laravel的新手,我只是在创建一个简单的应用程序,用户可以登录和注册,登录后在仪表板中写入帖子,然后尝试在仪表板中显示用户发布的数据,该数据保存在数据库中,但出现此错误:

未定义的变量:帖子(视图:C:\ xampp \ htdocs \ practiseapp \ resources \ views \ dashboard.blade.php)

我认为我已经定义了帖子,我不知道出了什么问题,任何帮助将不胜感激,谢谢。...

我的仪表板:

@extends('layout.master')

@section('content')
<div class="col-sm-6 col-sm-offset-3">
    <header><h3>What do you wanna say</h3></header>
    <form method="post" action="{{route('post.create')}}">
        {{csrf_field()}}
        <div class="panel-body">
        <div class="form-group">
            <textarea class="form-control" name="body" id="body" rows="5" placeholder="Enter your post">

            </textarea>
        </div>
        <button type="submit" class="btn btn-primary">Create post</button>

    </form>
    </div>

</div>

<section class="row-posts">
    <div class="col-md-6 col-sm-offset-3">
        <header><h3>Other people posts</h3></header>

        @foreach($posts as $post)
        <article class="post">
            <p>{{ $post->body }}</p>
            <div class="info">
                posted by {{ $post->user->name}} on {{$post->created_at}}
            </div>
            <div class="interaction">
                <a href="#">Like</a>|
                <a href="#">Disike</a>|

        </article>
        @endforeach

我认为您已经很接近了,但是我有一些想法可能会对您有所帮助。

首先,您是否检查过routes/web.php中的路由设置正确?如果您使用了Laravel文档中的一些示例,则可能是您的路线返回了视图而未使用您编写的Controller。如果您有类似这样的内容:

Route::get('/', function () {
    return view('dashboard');
});

...那么您可能想要将其替换为以下内容:

Route::get( '/', 'PostController@show );

管理路由的方法有很多-Laravel Docs可以很好地解释其中的一些问题。

此外,当将内容从Controller传递到View时,我喜欢将对象分配给关联数组,然后在使用view方法时将该数组传递给该数组。这完全是个人喜好,但您可能会发现它很有用。像这样的东西:

public function show()
{
    // Create output array - store things in here...
    $output = [];

    $output[ "posts" ] = Post::all();

    // Render the Dashboard view with data...
    return view( 'dashboard', $output );
}

希望其中一些帮助!

尝试以下代码,

<?php

    namespace App\Http\Controllers;

    use App\Http\Requests;
    use App\Post;
    use App\UserTypes;

    use Auth;
    use Hashids;
    use Redirect;
    use Illuminate\Http\Request;
    use Hash;

    class PostController extends Controller
    {

        public function show()
        {
            //Fetching all the posts from the database
            $posts = Post::get();
            return view('dashboard', compact('posts'));
        }

        public function store(Request $request)
        {
            $this->validate($request,[
                'body' => 'required'

            ]);

            $post = new Post;
            $post->body = $request->body;
            $request->user()->posts()->save($post);

            return redirect()->route('dashboard');      
        }
    }
