Question

我有这个动作，我想保存，$newtkamount到数据库，我尝试使用我用于我的注册页面的相同代码（显然指向不同的表）但我无法得到什么都可以解决这个问题。它需要根据当前用户用户ID

重写已存在的值

public function actionBuy($qty=0) {
    $_id = Yii::app()->user->getId();
    $model = Tokens::model()->findByAttributes(array('UserID' => $_id));
    if ($model === null)
        throw new CHttpException(404, "Keep calm! If you havent bought tokens before this is normal");


    $this->render('buy', array(
        'model' => $model,));

    if (strtoupper($_SERVER['REQUEST_METHOD']) == 'POST'){
        $_qty = $_POST['qty'];
        $newtkamount = ($model->TokenAmount + $_qty);

        echo $newtkamount . $model->TokenAmount;
    }
}

保存数据后始终渲染，不要在控制器中使用echo。

public function actionBuy($qty=0) {
    $_id = Yii::app()->user->getId();
    $model = Tokens::model()->findByAttributes(array('UserID' => $_id));
    if ($model === null)
        throw new CHttpException(404, "Keep calm! If you havent bought tokens before this is normal");

    if (strtoupper($_SERVER['REQUEST_METHOD']) == 'POST'){
        $_qty = $_POST['qty'];
        $model->TokenAmount = ($model->TokenAmount + $_qty);
        $model->save(false);
    }

    $this->render('buy', array(
        'model' => $model));
}

将数据保存到数据库
