Question

我正在尝试临时存储数据并在其他一些页面中打印。所选数据仅在我刷新页面之前存在。我该如何解决？谢谢。

index.blade.php

<form action="" method="post">
{!! Form::select('first_name', $firstNames) !!}
<button type="submit" value="Submit">Go</button>
</form>

DashboardController.php

public function getIndex( Request $request )
{

    $this->data['online_users'] = \DB::table('tb_users')->orderBy('last_activity','desc')->limit(10)->get();
    $this->data['firstNames'] = \DB::table('tb_users')->orderBy('first_name')->lists('first_name', 'id');
    $request->session()->put('first_name', input::get('first_name'));
    $this->data['active'] = '';
    return view('dashboard.index',$this->data); 

}

回声

<p>{{Session::get('first_name')}}</p>

Answer 1

使用会话变量来跨页面保存数据

第1页

{{Session::put('firstName','John')}}

第2页

{{Session::get('firstName')}}

所以试试这个

public function getIndex( Request $request )
{

$this->data['online_users'] = \DB::table('tb_users')->orderBy('last_activity','desc')->limit(10)->get();
$this->data['firstNames'] = \DB::table('tb_users')->orderBy('first_name')->lists('first_name', 'id');
\Session::put('first_name', $request->get('first_name'));
$this->data['active'] = '';
return view('dashboard.index',$this->data); 

}

将您的路线添加到网络中间件以使用会话！

<强> routes.php文件

Route::group(['middleware' =>['web']],function(){

 Route::get('myroute','DashboardController@getIndex');

});

Answer 2

尝试将compact('data')替换为$data

Answer 3

尝试这样做

public function getIndex( Request $request )
{
  $data['online_users'] = \DB::table('tb_users')->orderBy('last_activity','desc')->limit(10)->get();
  $data['firstNames'] = \DB::table('tb_users')->orderBy('first_name')->lists('first_name', 'id');
  $data['first_name'] = input::get('first_name');
  $data['active'] = '';
  return view('dashboard.index')->with('data', $data);
}

像这样查看

<p>{{ $data['first_name'] }}</p>

Answer 4

对于商店会议： - 会话（[＆＃39; first_name＆＃39; =＆gt; $ request-＆gt; get（＆＃39; first_name＆＃39;）]）

获取会话值： - 会话（＆＃39;如first_name＆＃39）
