严格标准：非静态方法 MenuHelper::getArticleByID() 不应该被静态调用

Question

刚开始学习 joomla，在 php 方面有点不好，我不知道如何进行非静态调用。收到此错误：严格标准：不应在

中静态调用非静态方法 MenuHelper::getArticleByID()

<?php 

defined('_JEXEC') or die;

$base = JURI::base(true);
$menu = JFactory::getApplication()->getMenu();
$item = $menu->getMenu();

include __DIR__ . '/helper.php';

?>

感谢您的宝贵时间！

Answer 1

嗯，错误消息已经告诉你，MenuHelper 中的方法似乎没有被定义为

public static function getArticleByID (...)

因此，您可以做的是在包含之后获取 MenuHelper 的一个实例。

$menuHelper = new MenuHelper();

然后替换

MenuHelper::getArticleByID()

在您的代码中使用

$menuHelper->getArticleByID()

。现在您应该摆脱错误消息。
