Why is the date value erased on transfer?

Question

Yii

Hello. In the code below, when the button is clicked, the date_subscription_end value should be updated. But, as a result, date_subscription takes a null value (stored in the database in int format). Having set new values, I checked at each stage why this is so, and it turned out that when saving, it erases the date, why is this possible?

public function actionSubscription(){
        $jd = Yii::$app->request->post();
        $jd = (object)$jd;

        Yii::$app->user->setIdentity(\common\models\User::findOne(['id'=>$jd->data]));

        $userSettings = UserSettings::findOne(["user_id" => $jd->data]);
        if ($userSettings->subscription == 1){
            $userSettings->subscription = 0;
            echo "date_subscription:".$userSettings->date_subscription."\n";
            echo "date_subscription_end:".$userSettings->date_subscription_end."\n";
        } else {
            $userSettings->subscription = 1;
           // $userSettings->date_subscription = date('Y-m-01');
            echo "date_subscription:".$userSettings->date_subscription."\n";
            $userSettings->date_subscription_end=date('Y-m-d', strtotime('+3 month'));
            echo "date_subscription:".$userSettings->date_subscription."\n";
            echo "date_subscription_end:".$userSettings->date_subscription_end."\n";
        }
if ($userSettings->save()){
            echo ".$userSettings->date_subscription." user_id: ".$userSettings->user_id." use_smart_publish: ".$userSettings->subscription. " date_subscription:".$userSettings->date_subscription;
        }

Here is the request

$(document).ready(function(){
        $(".user_subscription").click(function(){
            if (confirm ("Продлить подписку?")) {
                jQuery.ajax({
                    url: '/admin/clients/subscription',
                    type: 'post',
                    contentType: 'application/x-www-form-urlencoded',
                    async: true,
                    dataType: 'html',
                    data: {
                        data: this.name
                    },
                    success: function (data) {
                        alert(data);
                    },
                    error: function () {
                        alert("Error");
                        location.reload();
                    }
                });
            }
        });
    });

Answer 1

KevinSmash , in beforeValidate, look carefully... strtotime is called in the same place. You
need to know that when save is called, other functions are also
called .
)->beforeSave()->save()->afterSave()
And when we set save(false) then
beforeSave()->save()->afterSave()
Read the Yii2 documentation, so you can talk for a very long time
