Laravel 会话闪存保留 2 个请求

最近我从Codeigniter换成了Laravel，一切都很好，除了我遇到了一个问题。Session::flash

当我创建新用户时，我收到成功消息，但它将持续2个请求，即使我没有通过验证器：

我的代码在：UsersController

function getCreateUser(){
    $config = array(
        'pageName' => 'createUser',
        'pageTitle' => 'Create User',
        'formUrl'   => action('UsersController@postCreateUser'),
        'modelFields'   => array(
            array('db_name' => 'employee_id', 'text' => 'Employee Id', 'mandatory' => TRUE),
            array('db_name' => 'full_name', 'text' => 'Full Name', 'mandatory' => TRUE),
            array('db_name' => 'email', 'text' => 'Email', 'mandatory' => FALSE),
            array('db_name' => 'password', 'text' => 'Password','value' => '12345', 'mandatory' => TRUE)
            ),
        'submit_text' => 'Create'
        );
    return View::make('layouts.form', $config);
}

function postCreateUser(){
    $config = array(
        'pageName' => 'createUser',
        'pageTitle' => 'Create User',
        'formUrl'   => action('UsersController@postCreateUser'),
        'modelFields'   => array(
            array('db_name' => 'employee_id', 'text' => 'Employee Id', 'mandatory' => TRUE),
            array('db_name' => 'full_name', 'text' => 'Full Name', 'mandatory' => TRUE),
            array('db_name' => 'email', 'text' => 'Email', 'mandatory' => FALSE),
            array('db_name' => 'password', 'text' => 'Password','value' => '12345', 'mandatory' => TRUE)
            ),
        'submit_text' => 'Create'
        );
    $validator = User::validate(Input::all());
    if($validator->passes()){
        $user = new User(Input::all());
        $user->password = Hash::make(Input::get('password'));
        $user->Company_id = '1';
        $user->save();

        Session::flash('message', 'User Created Successfully!'); 
        Session::flash('alert-class', 'alert-success');
        return View::make('layouts.form', $config);
    } 

    return View::make('layouts.form', $config)->withErrors($validator->messages());
}

在：form.blade

@if ( $errors->count() > 0 )
<div class="alert alert-danger">
    <p>The following errors have occurred:</p>

    <ul>
        @foreach( $errors->all() as $message )
        <li>{{ $message }}</li>
        @endforeach
    </ul>
</div>
@endif

在：master.blade

@if(Session::has('message'))
<p class="alert {{ Session::get('alert-class', 'alert-info') }} alert-dismissable"> {{ Session::get('message') }}</p>
@endif

也许我并不孤单，这是另一个悬而未决的问题。

更新

对于将来面临此问题的任何人：永远不要在没有重定向的情况下刷新会话数据。

我的代码现在如下所示：

function postCreateUser(){
    $validator = User::validate(Input::all());
    if($validator->passes()){
        $user = new User(Input::all());
        $user->password = Hash::make(Input::get('password'));
        $user->Company_id = '1';
        $user->save();

        Session::flash('message', 'User Created Successfully!'); 
        Session::flash('alert-class', 'alert-success');
    } else {
        Session::flash('message', Helpers::formatErrors($validator->messages()->all()));
        Session::flash('alert-class', 'alert-danger');
    }

    return Redirect::action('UsersController@getCreateUser');
}
