我如何将输入值（日期选择器）发送到控制器，而不是操作。我有一些动作，需要更改日期值，我必须从datepicker的输入中获取日期值。我是yii2的新手，但我没意识到。我发现了有关通过ajax发送数据的信息，但是ajax仅通过一个动作发送数据（imho）。提前致谢。 （对不起，我的英语不好 ）。目前，动作按date（）起作用。
这是我的行动示例。
public function actionPara_foiz($fac, $cour, $smena, $lesson_id)
{
if($cour == "")
{

{
$course1['percent'] = (Attend::find()->where(['faculty_id' => $fac, 'course_id' => 1, 'lesson_id' => $lesson_id, 'shift_id' => $smena, 'attend' => 0, 'date' => date('Y-m-d')])->count() / Student::find()->where(['faculty_id' => $fac, 'course_id' => 1, 'shift_id' => $smena])->count()) * 100;
}
else

为什么不尝试使用jquery / ajax来获取设置日期时间选择器的时间，然后通过发布或获取请求将日期数据传递给控制器。
答案 1 :(得分：0)
我用queryParams解决了这个问题；
$params = Yii::$app->request->queryParams;
$params[date] // this given value when user request date
我不知道这是否是正确的决定，但是我使用了它。
