Добавление заголовков title, keywords и description на сайте под MediaWiki 1.6
Материал из Викиреальностя
Чтобы на странице MediaWiki изменить отображаемый заголовок страницы по сравнению с ее названием, используют конструкцию вида:
{{DISPLAYTITLE:Новое название страницы}}
в тексте викистраницы. На стороне сервера в LocalSettings.php должно быть включено
$wgAllowDisplayTitle = true; $wgRestrictDisplayTitle = false;
Для добавления заголовков title, keywords и description в HTML-код (они нужны для поисковиков) можно использовать расширение http://www.mediawiki.org/wiki/Extension:Add_HTML_Meta_and_Title которое подключается из LocalSettings.php строчкой
require_once("$IP/extensions/Add_HTML_Meta_and_Title/Add_HTML_Meta_and_Title.php");
Текст файла Add_HTML_Meta_and_Title.php в допиленном до рабочего состояния виде выглядит следующим образом:
