Session :: flash（＆＃39;成功＆＃39;，＆＃39;数据已成功保存＆＃39;）;

Question

我使用以下代码显示flash消息，但它无效。

的 PostController中

public function store(Request $request){
$this->validate($request,array(
'title'=>'required|max:255',
'slug'  =>'required|alpha_dash|min:5|max:255|unique:posts,slug',
'body'  =>'required'
 ));

    //store in the database

    $post = new Post;
    $post->title = $request->title;
    $post->slug  = $request->slug;
    $post->body = $request->body;

    $post->save();

    //This code will generate flash message about success or failure about data insert

     Session::flash('success', 'Data has been saved successfully!');

    //Redirect to another page
    return redirect()->route('posts.show', $post->id);

}

然后要显示它，使用以下代码：

message.blade.php

@if(Session::has('success'))
    <div class="alert alert-success" role= "alert">
        <strong>Successful:</strong>
            {{ Session::get('success') }} 
    </div>
@endif
@if(count($errors) > 0)
    <div class="alert alert-danger" role="alert">
        <strong>Errors:</strong>
            <ul>
                @foreach($errors as $error)
                    <li>  {{ $error }} </li>
                @endforeach
            </ul>
    </div>
@endif

上面的代码没有显示任何Flash消息。但当 Session :: flash（＆＃39;成功＆＃39;，＆＃39;数据已成功保存！＆＃39;）; 写作：     Session :: put（＆＃39;成功＆＃39;，＆＃39;数据已成功保存！＆＃39;）;

显示flash消息但不会消失。

routes.php是：

Route :: group（[＆＃39; middleware＆＃39; =＆gt; [＆＃39; web＆＃39;]]，function（）{

Route::get('auth/login', ['as' =>'login', 'uses'=>
     'Auth\AuthController@getLogin']);
Route::post('auth/login', 'Auth\AuthController@postLogin');
Route::get('auth/logout', ['as' => 'logout', 'uses' =>
    'Auth\AuthController@getLogout']);


Route::get('auth/register','Auth\AuthController@getRegister');
Route::post('auth/register','Auth\AuthController@postRegister');


Route::get('password/reset/{token?}',
    'Auth\PasswordController@showResetForm');
Route::post('password/email',
    'Auth\PasswordController@sendResetLinkEmail');
Route::post('password/reset','Auth\PasswordController@reset');

Route::get('contact', 'PagesController@getContact');
Route::get('about', 'PagesController@getAbout');
Route::get('/', 'PagesController@getIndex');


Route::get('reader/{slug}', ['as' => 'reader.single', 'uses' =>
    'ReaderController@getSingle'])
     ->where('slug', '[\w\d\-\_]+');


Route::get('reader', ['as' => 'reader.index', 'uses' =>
    'ReaderController@getIndex' ]);

Route::resource('posts', 'PostController');
});

请帮忙！

1.-确保您是否在视图中包含消息模板，在本例中为SHOW视图 2.-尝试替换您的消息模板：

@if(Session::has('success'))
    <div class="alert alert-success" role= "alert">
        <strong>Successful:</strong>
            {!! session('success') !!}
    </div>
@endif
@if(count($errors) > 0)
    <div class="alert alert-danger" role="alert">
        <strong>Errors:</strong>
            <ul>
                @foreach($errors as $error)
                    <li>  {{ $error }} </li>
                @endforeach
            </ul>
    </div>
@endif

看，我正在使用{!!会话（＆＃39;成功＆＃39;）!!}而不是你的
