Question

我的操作在控制器中创建

public function actionCreate()
{
    $model = new User();

    if ($model->load(Yii::$app->request->post()) && $model->save()) {
        return $this->redirect(['view', 'id' => $model->id]);
    } else {
        return $this->render('create', [
            'model' => $model,
        ]);
    }
}

数据库：

tb_leave

id
id_employee <fk>
startdate
enddate
duration
leave_type //enum 'annual leave','medical check'

tb_employee
id
name
address
total_leave

逻辑是// if "total_leave" >= "duration" && leave_type = "Annual Leave"然后是total_leave - duration。结果在tb_employee中插入total_leave。

有人可以帮我解决这个问题吗？

将toSave函数添加到tb_leave模型类，如下所示，并更新total_leave值。

/**
 * @inheritdoc
 */
public function beforeSave($insert)
{
    if (parent::beforeSave($insert)) {

        $user = User::find()->where(['id' => this->id_employee])->one();

        if($user->total_leave >= this->duration && this->leave_type = "annual Leave"){
            $user->total_leave = $user->total_leave - this->duration;
            $user->save();
        }

        return true;
    } else {
        return false;
    }
}

在保存tb_leave之前，每次都会触发此函数。
