成功とエラーメッセージは表示されません

Question

こんにちは私はlaravelの新機能です。追加された1つの投稿にページを作成しましたが、何らかの理由で成功とエラーメッセージが表示されません。いくつかのフィールドが必要とされているが..私のコントローラで私は、このメソッドを使用していますと、postCreatePost

<?php 

namespace App\Http\Controllers; 
use Illuminate\Http\Request; 
use App\Post; 
use App\Catgory; 

class PostController extends Controller { 
    public function getBlogIndex() { 
     return view ('frontend.blog.index'); 
    } 

public function getSignlePost($post_id, $end = 'frontend') { 
    return view ($end, '.blog.single'); 
} 

public function getCreatePost() { 
    return view('admin.blog.create_post'); 
} 

public function postCreatePost(Request $request) { 
    $this->validate($request, [ 
     'title'  => 'required|max:120|unique:posts', 
     'author' => 'required|max:80', 
     'body'  => 'required' 
    ]); 

    $post   = new Post(); 
    $post->title = $request['title']; 
    $post->author = $request['author']; 
    $post->body  = $request['body']; 

    $post->save(); 

    //Attaching categories 

    return redirect()->route('admin.index')->with(['success','Post sucessfully created!']); 
} 
} 

これは

@extends('layouts.admin-master') 

@section('styles') 
    <link rel="stylesheet" href="{{ URL::secure('src/css/form.css') }}" type="text/css" /> 
@endsection 

@section('content') 
    <div class="container"> 
     @section('styles') 
      <link rel="stylesheet" href="{{ URL::to('src/css/common.css') }}" type="text/css" /> 
     @append 

    @if(Session::has('fail')) 
     <section class="info-box fail"> 
      {{ Session::get('fail') }} 
     </section> 
    @endif 

    {{ var_dump(Session::get('success')) }} 

    @if(Session::has('success')) 
     <section class="info-box success"> 
      {{ Session::get('success') }} 
     </section> 
    @endif 

    @if(count($errors) > 0) 
     <section class="info-box fail"> 
      <ul> 
       @foreach($errors->all() as $error) 
        <li>{{ $error }}</li> 
       @endforeach 
      </ul> 
     </section> 
    @endif 

    <form action="{{ route('admin.blog.post.create') }}" method="post"> 
     <div class="input-group"> 
      <label for="title">Title</label> 
      <input type="text" name="title" id="title" {{ $errors->has('title') ? 'claass=has-error' : '' }} /> 
     </div> 

     <div class="input-group"> 
      <label for="author">Author</label> 
      <input type="text" name="author" id="author" {{ $errors->has('author') ? 'claass=has-error' : '' }} /> 
     </div> 

     <div class="input-group"> 
      <label for="category_select">Add Categories</label> 
      <select name="category_select" id="category_select"> 
       <!-- Foreach loop to output categories --> 
       <option value="Dummy Category ID">Dummy Category</option> 
      </select> 
      <button type="button" class="btn">Add Category</button> 
      <div class="added-categories"> 
       <ul></ul> 
      </div> 
     </div> 

     <input type="hidden" name="categories" id="categories"> 

     <div class="input-group"> 
      <label for="body">Body</label> 
      <textarea name="body" id="body" cols="30" rows="10" {{ $errors->has('body') ? 'claass=has-error' : '' }}></textarea> 
     </div> 

     <button type="submit" class="btn">Create Post</button> 

     <input type="hidden" name="_token" value="{{ Session::token() }}"> 
    </form> 
</div> 
@endsection 

@section('scripts') 
    <script type="text/javascript" src="{{ URL::secure('src/js/posts.js') }}"></script> 
@endsection 

マイルートのWebミドルウェア内部の私の見解である

Route::group(['middleware' => ['web']], function() {  
Route::get('/about', function() { 
    return view('frontend.other.about'); 
})->name('about'); 


Route::group([ 
    'prefix' => '/admin'  
], function() { 
    Route::get('/', [ 
     'uses' => 'AdminController@getIndex', 
     'as' => 'admin.index' 
    ]); 

    Route::get('/blog/posts/create', [ 
     'uses' => 'PostController@getCreatePost', 
     'as' => 'admin.blog.create_post' 
    ]); 

    Route::post('/blog/post/create', [ 
     'uses' => 'PostController@postCreatePost', 
     'as' => 'admin.blog.post.create' 
    ]); 
}); 
}); 

、あなたは間違った構文を使用しているモデル

<?php 

namespace App; 

use Illuminate\Database\Eloquent\Model; 

class Post extends Model 
{ 
    public function categories() { 
     return $this->belongsToMany('App\Category', 'posts_categories'); 
    } 
} 

Answer 1

。この方法を試してください。

return redirect()->route('admin.index')->with('success','Post sucessfully created!');
