致命錯誤：調用布爾型上的成員函數getId（）

Question

當我嘗試創建XML/Soap用戶時，顯示此錯誤，我單擊添加用戶並出現此錯誤。

致命錯誤：調用成員函數getId（）布爾值在/var/www/vhosts/domain.com/httpdocs/app/code/core/Mage/Adminhtml/controllers/Api/UserController.php在線74

這是我UserController.php

<?php

，當我啓用了錯誤報告，我看到這個錯誤日誌

mod_fcgid: stderr: PHP Fatal error: Call to a member function getId() on boolean in /var/www/vhosts/domain.com/httpdocs/app/code/core/Mage/Adminhtml/controllers/Api/UserController.php on line 74, referer: http://www.domain.com/index.php/admin/api_user/index/key/b2a855c2e5d82b8a3ba010f07f3883af/ 

，我看到這在我的瀏覽器，當我點擊添加新用戶在SOAP/XML-RPC用戶中。

Fatal error: Call to a member function getId() on boolean in /var/www/vhosts/domain.com/httpdocs/app/code/core/Mage/Adminhtml/controllers/Api/UserController.php on line 74

查找到什麼在此背景下的load（）函數返回：

$model = Mage::getModel('api/user')->load($id); 

早些時候在你的腳本，你做一個：

$model = Mage::getModel('api/user'); 

接着是

$model->load($id); 

我想你在哪裏：

$model = Mage::getModel('api/user')->load($id); 

你也需要做：

$model = Mage::getModel('api/user'); 
$model->load($id); 

我不能肯定地說，沒有你提供更多的代碼，但我猜想，load（）函數「負荷」對應的$ id的通過設置某些類變量將值賦予對象並返回True或False;它不會返回加載的對象本身。
