我有一个 Joomla 网站，里面有一个 PHP 脚本。有一个按钮可以将人们重定向到 PHP 脚本。我想使用我的 Joomla 站点用户组作为访问级别。应阻止未登录的人访问 PHP 脚本的index.php并收到诸如“您必须先登录！”之类的消息。而那些已登录的用户，可以访问 PHP 脚本的index.php。
我所做的就是在PHP 脚本的index.phpJFactory::getUser();顶部包含 Joomla 框架，并将函数： . 之后，我将整个index.php置于一个if-else条件下。的条件是不等于“guest”if的返回值。getUser()
该else部件工作正常并显示消息“您必须先登录”，但该if部件不起作用，只显示一个空白页面，我收到 #
error 500 "internal server error"
这意味着我的代码可以识别那些已登录的和未登录的。此外，当我删除我的个人代码时，它会正确地向所有人显示index.php 。
请帮帮我
