Question

我是我的工作所需的YII框架的新手，我一直有这个错误，虽然我有意见/用户/管理员，用户控制器和用户（模型）我不知道它有什么问题，我完全糊涂了..我在跳，有人可以帮助我..

Answer 1

这里：

public function actionAdmin() {
    $model = new User('search');
    $model->unsetAttributes();  // clear any default values
    if (isset($_GET['User']))
    $model->attributes = $_GET['User'];

    $this->render('admin', array(
    'model' => $model,
    'User' => $User // <------ UNDEFINED
    ));
}

$ User 未在此方法的范围内定义。

如果它是数据库对象，则必须将其作为ActiveRecord检索：

MyTable::model()->findByPk($theUSerId)

或类似的东西。

如果是应用用户：Yii::app()->user就可以了。

更有可能的是，您已将其作为 $ model ：

$model = new User('search');

这取决于您转发到视图的 $ User 变量。强调文字

YII未定义变量
