我正在尝试从header.php调用下面的函数。但我得到一个错误。当我从我的视图文件（profile.php）中调用它时，它可以正常工作。
在我的 /model/User.php
中public function getAvatar() {
$dir = 'uploads/user';
$img = $this->avatar_link;
$full_img_dir = './'.$dir.'/'.$this->id.'/'.$img;
return (!empty($this->avatar_link) && file_exists($full_img_dir))
? Yii::app()->request->baseUrl.'/'.$dir.'/'.$this->id.'/'.$img
: Yii::app()->request->baseUrl.'/images/blank_profile.gif';
}
这是我得到的错误
Property "UserController.avatar_link" is not defined.
我正在调用这个函数
<img class="img-rounded user-avatar" src="<?php echo User::getAvatar(); ?>" title="<?php echo Yii::app()->user->username; ?>" />
这是我的 models / User.php
<?php

您将非静态方法称为静态，使用$ this而不使用任何对象，这是您的错误。 如何实现你想要的？ 首先你必须有User对象，使用$ this和非静态方法。
$user = User::model()->findByPk(Yii::app()->user->id);
接下来（如果你有所有领域）你可以称之为：
<img class="img-rounded user-avatar" src="<?php echo $user->getAvatar(); ?>" title="<?php echo Yii::app()->user->username; ?>" />
在这种情况下，你的$ this in function将是用户模型，否则它的控制器（在所有视图中$ this这是控制器）。你也可以将它用作$user->avatar，因为它是yii getter。
修改
如何使用Yii::app()->user->avatar_link
1st。制作您的WebUser类并将其添加到components-＆gt;用户部分的配置中（我假设它已经存在）
'user' => array(
'class' => 'RWebUser',
第二。为avatar_link制作getter和setter：
public function setAvatar_link($avatar_link)
{
$this->setState('User_avatar_link', $avatar_link);
}
public function getAvatar_link()
{
$this->getState('User_avatar_link');
}
第3次。将逻辑添加到afterlogin()以获取您的头像链接：
public function afterLogin($fromCookie)
{
parent::afterLogin($fromCookie);
$user = User::model()->findByPk(Yii::app()->user->id);
$id = $user->id;
$dir = 'uploads/user';
$img = $user->avatar_link;
$full_img_dir = './'.$dir.'/'.$id.'/'.$img;
$avatar_link = (!empty($img) && file_exists($full_img_dir))
? Yii::app()->request->baseUrl.'/'.$dir.'/'.$id.'/'.$img
: Yii::app()->request->baseUrl.'/images/blank_profile.gif';
$this->setAvatar_link($avatar_link);
}
现在您可以将它与Yii::app()->user->avatar_link一起使用，它将存储在会话中，并在用户登录时再查询一次。

将其称为User :: model（） - ＆gt; getAvatar（）而不是User :: getAvatar（）;
