准备[编辑]

  • 一只手,或其他用于操作计算机或屏幕的工具。
  • 一个账号,如有特殊情况,也可不登录创建。
  • 对于所要创建条目的构思。

主名字空间普通条目的创建[编辑]

特殊页面法[编辑]

使用特殊:创建页面

搜索不到创建法[编辑]

  • 在右上角键入需要创建的条目的名称,不要含有如#、/、{}、[]等会被解析的字符。
  • 点击红链进入创建页面。

红链创建法[编辑]

  • 在任意位置编辑[[页面名]]
  • 点击红链进入创建页面。

链接跳转法[编辑]

  • 浏览器地址栏键入https://nmfwiki.miraheze.org/wiki/页面名
  • 点击创建页面提示进入创建页面。

直接跳转法[编辑]

  • 浏览器键入https://nmfwiki.miraheze.org/w/index.php?title=页面名&action=edit&redlink=1进入创建页面。

子页面的创建[编辑]

方法与前者大体相同,只需要将页面名替换为父页面名/子页面名即可。

特定名字空间页面的创建[编辑]

方法与前者大体相同,只需要将页面名替换为名字空间:页面名即可。

  • 请在创建前确定Wiki含有此名字空间
  • 名字空间亦可使用别名,如Template等同于模板
  • 特殊名字空间无法创建
    • 这是通过一个扩展中includes/specials/Special[名字].php创建的,以下提供封禁用户的页面的代码。

特定名字空间子页面的创建[编辑]

方法与前者大体相同,只需要将页面名替换为名字空间:父页面名/子页面名即可。
