Laravel - 在会话中存储选定的数据

Question

会话中的数据仅在页面刷新之前存在:(如何让它活得更久？

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();
    $this->data['firstNames'] = \DB::table('tb_users')->orderBy('first_name')->lists('first_name', 'id');
    print_r($this->data['firstNames']);
    \Session::put('firstNames',Input::get('first_name'));
    $this->data['active'] = '';
    return view('dashboard.index',$this->data);
}

Answer 1

你可以这样做：

return view('dashboard.index')->with(['data', $this->data]);

Answer 2

使用compact

$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['firstName'] = Input::get('first_name'));
$data['active'] = '';
return view('dashboard.index', compact('data'));

然后您将能够访问所有值：

• {{ $data['firstNames'] }}
• {{ $data['firstName'] }}
• {{ $data['online_users'] }}
• {{ $data['active'] }}

在这种情况下不需要会话
