Question

我是Laravel的新手保存在数据库中的仪表板中的数据，但我遇到了此错误：

未定义的变量：帖子(查看：c： xampp htdocs ractiSeApp resources views view dashboard.blade.blade.php(

我认为我已经定义了帖子，我不知道有什么问题，任何帮助将不胜感激。...

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>

Answer 1

我认为您非常接近，但是我有一些想法可以帮助您。

首先，您是否检查了您的路线是否正确设置在routes/web.php中？如果您使用了Laravel文档中的一些示例，则可能在不使用您编写的控制器的情况下返回视图。如果您有这样的东西：

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

...然后您可能想用这样的东西替换它：

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

有许多不同的方法来管理您的路由 - Laravel文档将在解释其中一些方面做得很好。

另外，当将事物从控制器传递到视图时，我喜欢将对象分配给关联数组，然后在使用视图方法时传递该数组。这完全是个人喜好，但您可能会发现它有用。有点这样的东西：

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 );
}

希望其中一些会有所帮助！

尝试以下代码，

<?php
    namespace AppHttpControllers;
    use AppHttpRequests;
    use AppPost;
    use AppUserTypes;
    use Auth;
    use Hashids;
    use Redirect;
    use IlluminateHttpRequest;
    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');      
        }
    }
