我正在使用这本名为PHP5社交网络的社交网站。 我试图编辑个人资料但我收到此错误
致命错误：在非对象上调用成员函数getObject（），该对象引用以下行;
if ( $registry->getObject('authenticate')->isLoggedIn()
&& ( $registry->getObject('authenticate')->getUser()->getUserID() == $this->id
|| $registry->getObject('authenticate')->getUser()->isAdmin() == true ) )
我是PHP的新手，所以任何帮助都会受到极大的赞赏。
这是整个文件;

有没有人可以提供帮助？ 如果它有帮助，我会将源代码发送到您的电子邮件中吗？
提前致谢：）
答案 0 :(得分：2)
您没有引用要访问的对象属性$registry，而是未定义的局部变量$registry。将行更改为：
if( $this->registry->getObject('authenticate')->isLoggedIn() && ( $this->registry->getObject('authenticate')->getUser()->getUserID() == $this->id || $this->registry->getObject('authenticate')->getUser()->isAdmin() == true ) )
... 或将此行添加到现有行之上：
$registry = $this->registry;
我会选择第一个选项，但实际上它没什么区别。
