Laravel-找不到功能要求

Question

我已经将相同的日期请求参数传递给了索引和列表函数。参数显示在索引功能中，而不显示在列表功能中。 我究竟做错了什么？ 附有代码

public function index(Request $request){

    ....

    $from_date = $request->input('from_date') ? : '';
    $to_date = $request->input('to_date') ? : '';

    return view('payroll.index',compact('col_heads','from_date', 'to_date', 'menu','table_info'));
}

public function postPayrollList(PostPayrollRequest $request){
    $response = ['message' => trans('messages.request_submit'), 'status' => 'success'];
    return response()->json($response, 200, array('Access-Controll-Allow-Origin' => '*'));
}

public function lists(PostPayrollRequest $request){
    ....
        $from_date = $request->input('from_date') ? : '';
        $to_date = $request->input('to_date') ? : '';
        ....
}

路线：

Route::get('/payroll','PayrollController@index');
Route::post('/payroll', array('as'=>'payroll.index','uses'=>'PayrollController@postPayrollList'));
Route::post('/payroll/lists','PayrollController@lists');
