尝试将 PHP 添加到 Joomla 网站时崩溃了
我以前从未做过任何 php 编码，但我使用的是来自 chronoforums 的论坛扩展，并且我正在尝试向论坛添加一些 php，以便如果用户登录，它将显示欢迎:$user如果没有，它将显示一个链接登录/注册.这是我试过的代码，但它使论坛页面崩溃了.
guest;如果($状态== 1){$url = "/论坛/登录";echo "<a href="$url">登录/注册</a>";} 别的 {echo "<p>欢迎:{$user->用户名}</p>";}?>错误:

当您在 GCoreExtensionsChronoforumsHelpers 中工作时，JFactory 类位于全局空间，你只需要像这样添加前缀，例如
$user = JFactory::getUser();或者，您可以在顶部添加一个 use 语句，例如
命名空间 GCoreExtensionsChronoforumsHelpers;使用JFactory;参见 http://php.net/manual/language.namespaces.global.php
I've never done any php coding before, but I'm using a forum extension from chronoforums and I'm trying to add some php to the forums so that if the user is logged in it will display Welcome: $user and if not it will display a link Login/Register. Here is the code I tried, but it crashed the forum page.
<?php
$user = JFactory::getUser();
$status = $user->guest;
if($status == 1) {
$url = "/forum/login";
echo "<a href="$url">Login/Register</a>";
} else {
echo "<p>Welcome: {$user->username}</p>";
}
?>

解决方案
As you are working in GCoreExtensionsChronoforumsHelpers and the JFactory class is in the global space, you simply need to prefix it as such, eg
$user = JFactory::getUser();
Alternatively, you could add a use statement at the top, eg
namespace GCoreExtensionsChronoforumsHelpers;
use JFactory;
See http://php.net/manual/language.namespaces.global.php
