Erfolg und Fehlermeldung zeigt nicht

Question

Hallo ich bin neu zu Laravel ich Seite erstellt, um einzelne Beitrag hinzugefügt, aber aus irgendeinem Grund Erfolg und Fehler Nachrichten überhaupt nicht angezeigt, egal, ich füge erfolgreich einen neuen Beitrag oder leere Formular einreichen obwohl einige Felder müssen ausgefüllt werden .. in meinem Controller ich diese Methode bin mit 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!']); 
} 
} 

Das ist meine Ansicht

@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 

Meine Routen innerhalb Web-Middleware

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' 
    ]); 
}); 
}); 

Und das Modell

<?php 

namespace App; 

use Illuminate\Database\Eloquent\Model; 

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

Answer 1

Sie verwenden falsche Syntax. Versuchen Sie diese:

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