这是我的 UserController.php

public function actionCreate()

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

            return $this->render('create', [
                'model' => $model,
            ]);
        }
    }
}

i want use setPassword function in user model, where i must put beforesave function and i need to change actionCreate function ?

我想在用户模型中使用 setPassword 函数，我必须在其中放置 beforesave 函数，我需要更改 actionCreate 函数？

You should place it in your model, because this method is located in yii\db\BaseActiveRecord. Override it as mentioned in official docs:

你应该把它放在你的模型中，因为这个方法位于yii\db\BaseActiveRecord. 如官方文档中所述覆盖它：

/**
 * @inheritdoc
 */
public function beforeSave($insert)
{
    if (parent::beforeSave($insert)) {
        // Place your custom code here

        return true;
    } else {
        return false;
    }
}

Official docs:

官方文档：

• yii\db\BaseActiveRecord beforeSave()
