覆盖 Joomla 核心组件文件 [英] Overriding Joomla core component file

问题描述

我正在尝试使用此 页面

它说我必须在基本目录中创建一个名为code"的文件夹并创建相同的目录结构.我试过了，但它不起作用.有人可以确认它是否有效.

It says I have to create a folder named 'code' in base directory and create the same directory structure. I tried it , but its not working. Can someone confirm whether its working.

我应该在哪里创建代码文件夹?是否在 joomla 安装的根目录下?

Where should I create code folder? Is it on root of joomla installations?

PS- 应用于核心文件时，编辑工作正常

PS- The edit is working correctly when applied on core file

推荐答案

您可以覆盖(几乎)Joomla 中的任何类，如果具有相同名称的类首先被加载.为确保这一点，您需要创建一个系统插件.

You can override (nearly) any class in Joomla, if your class with the same name is loaded first. To ensure that, you need to create a system plugin.

以下是 root/components/com_content/views/article/view.html.php 的示例:

Here is an example for root/components/com_content/views/article/view.html.php:

class plgSystemOverride extends JPlugin
{
    public function onAfterRoute()
    {
        JLoader::register('ContentViewArticle', 'path/to/override.php', true);
    } 
}

警告:如果您不十分小心，覆盖核心类可能会导致其他扩展出现问题.但是，对于视图，不太可能干扰其他扩展.

CAVEAT: Overriding a core class can lead to problems with other extensions, if you're not very careful. For views, though, any interferrence with other extensions is less likely.
