在mediawiki的页脚增加链接

说到在mediawiki的页脚增加链接
最常见的是要增加备案号的情况
网上比较流行的是在LocalSettings.php里增加以下代码块

$wgHooks['SkinTemplateOutputPageBeforeExec'][] = function($sk, &$tpl){
        $tpl->set('ICP_Number',Linker::makeExternalLink(
                'http://beian.miit.gov.cn/','萌ICP备7355608号-1'
        ));
        $tpl->data['footerlinks']['places'][]='ICP_Number';
        return true;
};

但是查阅 Manual:Hooks/SkinTemplateOutputPageBeforeExec 就会看到一条警示说已经不推荐使用了

This deprecated feature should no longer be used, but is still available for reasons of backwards compatibility. This feature was deprecated in version 1.35.0.

同时也指明了新的钩子SkinAddFooterLinks

Warning: If you can avoid using this hook, please do. Seek more specific hooks such as Manual:Hooks/SkinAddFooterLinks wherever you can.

后来在邮件列表里找到一段能用的新式代码

$wgHooks['SkinAddFooterLinks'][] = function( $skin, $key, &$footerlinks ) {
        if ( $key === 'places' ) {
                $footerlinks['test1'] = '<a href=#>Test Link1</a>';
                $footerlinks['test2'] = '<a href=#>Test Link2</a>';
        }
};
