You can use something like this:

你可以使用这样的东西：

public function store(PostRequest $request) {
    if (Post::create($request->all())) {
        $request->session()->flash('message.level', 'success');
        $request->session()->flash('message.content', 'Post was successfully added!');
    } else {
        $request->session()->flash('message.level', 'danger');
        $request->session()->flash('message.content', 'Error!');
    }
    return redirect('/');
}

In your blade file:

在您的刀片文件中：

@if(session()->has('message.level'))
    <div class="alert alert-{{ session('message.level') }}"> 
    {!! session('message.content') !!}
    </div>
@endif

The code above uses bootstrap's alert css classesfor styling and is inspired by Jeffrey Way's Laracasts Flash package

上面的代码使用bootstrap 的 alert css 类进行样式设置，灵感来自Jeffrey Way 的 Laracasts Flash 包

You can display flash messages in this way:

您可以通过以下方式显示 Flash 消息：

In your controller:

在您的控制器中：

$request->session()->flash('success', 'Record successfully added!');
//OR
$request->session()->flash('warning', 'Record not added!');

In your veiw:

在你看来：

@foreach (['danger', 'warning', 'success', 'info'] as $key)
 @if(Session::has($key))
     <p class="alert alert-{{ $key }}">{{ Session::get($key) }}</p>
 @endif
@endforeach

1. Write code like this in your Blade template:

   @if(Session::has('error'))
       <p class="alert alert-danger">{{ Session::get('error') }}</p>
   @endif
   

2. Write code like this in your Controller:

   Session::flash('error', 'Some thing is wrong. Please try again');
   Redirect::to(path to blade file route);
   

1. 在您的 Blade 模板中编写如下代码：

   @if(Session::has('error'))
       <p class="alert alert-danger">{{ Session::get('error') }}</p>
   @endif
   

2. 在您的控制器中编写这样的代码：

   Session::flash('error', 'Some thing is wrong. Please try again');
   Redirect::to(path to blade file route);

You can use ->with()in your controller

您可以->with()在控制器中使用

public function store(PostRequest $request) {
    if (!Post::create($request->all())) {
        return redirect('/')->with('error', 'Error!');
    }

    return redirect('/')->with('success', 'Post was successfully added!');
}

Your view could look like this:

您的视图可能如下所示：

@if (session('success'))
    <div class="alert alert-success">
        {{ session('success') }}
    </div>
@endif
@if (session('error'))
    <div class="alert alert-danger">
        {{ session('error') }}
    </div>
@endif

or (with additional CSS for alert-errorclass):

或（带有额外的alert-error类CSS ）：

@foreach (['error', 'success'] as $status)
    @if(Session::has($status))
        <p class="alert alert-{{$status}}">{{ Session::get($status) }}</p>
    @endif
@endforeach
