修改用户参数设置。
定义函数： 
public static function onGetPreferences( User $user, array &$preferences ) { ... }
附加钩子： 在extension.json中： 
{
	"Hooks": {
		"GetPreferences": "MediaWiki\\Extension\\MyExtension\\Hooks::onGetPreferences"
	}
}
调用自： 文件： preferences/DefaultPreferencesFactory.php
介面： GetPreferencesHook.php

有关使用此钩子的扩展示例，请参见Category:GetPreferences extensions/zh。


Since REL1_35:

Define function: 
public function onGetPreferences( $user, &$preferences ) { ... }
Attach hook: In extension.json: 
{
	"Hooks": {
		"GetPreferences": "example_tag"
	},
	"HookHandlers": {
		"example_tag": {
			"class": "MediaWiki\\Extension\\ExampleExtension\\Hooks",
			"services": [
				"MainConfig",
				"UserOptionsLookup"
			]
		}
	}
}
Interface: GetPreferencesHook.php

用法

参数

参数/选项 描述
$user 正在修改其首选项的用户
&$preferences 要提供给HTMLForm对象的首选项描述数组

选项卡和节

section数组键指定Preferences的哪个选项卡和部分包含您的首选项。 如果您的section值是foo/bar，这意味着您的首选项将出现在foo选项卡上(由系统消息prefs-foo命名)的bar部分(由系统消息prefs-bar命名)。 如果不存在这样的选项卡或部分，则会自动创建。

默认标签列表

标识符 显示为
personal 用户资料
rendering 外观
editing 编辑
rc 最近更改
watchlist 监视列表
misc 其他

支持的类型

可见类型

type可以采用在文件includes/htmlform/HTMLForm.php的HTMLForm::$typeMappings数组中找到的各种值，包括信息、多选、单选等。

大多数首选项以与HTMLFormField相同的格式存储，但在'type' => 'usersmultiselect'的情况下，应该从换行符分隔的用户名列表(表单小部件使用该列表)和换行符分隔的用户ID列表(存储在数据库中)执行转换。 有关这方面的例子，请参阅email-blacklist(核心)或echo-notifications-blacklist(Echo )的处理。

Floats

For float types, you can set min and max, which will be validated on save.

API参数设置

API首选项使用类型api。它们不会显示在Special:Preferences中。 They are usually set via custom front-end interfaces that call the API.

Note that you should not use 'type' => 'hidden' for API preferences (that type exists for HTML forms, not preferences).

默认首选项

要设置首选项的默认值(即为尚未自定义其首选项的新用户设置的值)，请将该设置添加到$wgDefaultUserOptions 全局变量。使用与钩子中的$preferences相同的键名。

或者，如果您正在编写扩展，可以将其添加到文件extension.json的DefaultUserOptions部分。
