No MediaWiki existem cinco tipos de ligações de hipertexto, ou hiperligações:

  1. Hiperligações internas para outras páginas da mesma wiki
  2. Hiperligações externas para páginas de outros sites na Internet
  3. Hiperligações externas para páginas internas da mesma wiki
  4. Hiperligações interwikis para outros sites da Internet, usando prefixos especiais registados antecipadamente
  5. Hiperligações interlínguas para outras wikis registadas como versões da wiki atual noutras línguas

Note, por favor, que esta lista não inclui as hiperligações para categorias nem as hiperligações para ficheiros, que são usadas, respetivamente, para colocar as páginas em categorias e para apresentar imagens ou outros ficheiros multimédia.

Hiperligações internas

Para criarHelp:Editing pages uma hiperligação interna para uma página na mesma wiki use dois parênteses retos, [[assim]]. Quando gravar ou antever as suas alterações, verá uma hiperligação para a página de destino. Se a página existir a hiperligação aparece a azul (como a palavra «criar» na primeira frase deste parágrafo); se a página não existir, a hiperligação aparecerá a vermelho (portanto a hiperligação [[assim]] é mostrada assim). Note que as cores podem ser diferentes se o esquema de cores padrão da wiki foi alterado. Seguir uma «hiperligação vermelha» (independentemente de ser mesmo vermelha) para uma página inexistente permite que o utilizador crie essa página.

Para tornar qualquer outro texto (não necessariamente o título da página) numa hiperligação, use uma barra vertical «|», assim: [[Help:Categories|hiperligações de categoria]] resulta em hiperligações de categoria.

A primeira letra do destino da hiperligação normalmente não diferencia minúsculas e maiúsculas (a não ser que a wiki seja configurada de modo contrário), o que quer dizer que as hiperligações podem ter a primeira letra maiúscula ou não (Como ajudar e como ajudar são equivalentes). Porém, qualquer outra letra na sequência tem de ser idêntica ao destino (Como ajudar e Como Ajudar não são equivalentes). Espaços no título da página podem ser representados com sublinhados (Como ajudar e Como_ajudar são equivalentes) mas usar sublinhados em hiperligações é evitado porque são visíveis no texto (embora isto pode ser evitado usando uma barra vertical «|»).

Se o título da página de destino é o mesmo da página que está a editar, o resultado é texto em negrito e não uma hiperligação (por exemplo, nesta página a notação [[Help:Links/pt]] tem o resultado Help:Links/pt). Se está a tentar criar uma hiperligação para a página atual, provavelmente quer direcionar a hiperligação para uma secção específica ou para uma âncora na página; veja os exemplos abaixo.

O MediaWiki usa a tabela pagelinks da base de dadosManual:Pagelinks table para manter uma lista de todas as hiperligações internas.

Revision numbers can be found in each page's edit history. (It is very common to see links to specific revisions implemented as external links because it's easy to cut-and-paste an entire URL to form an external link.)

[[Special:Diff/2393992]]

[[Special:Diff/2390639/2393992]]

External links

To create an external link, usually to a page at a different website, enclose the URL followed by space and the link text in single square brackets (see examples below). When you save or preview the page, you will see a link rendered slightly differently than an internal wikilink. It may be a different color and/or be followed by an arrow icon to show that it may lead to another site.

Descrição You type You get
External link with specified link text
[https://mediawiki.org MediaWiki]

Numbered external link
[https://mediawiki.org]

This is what happens if you omit the link text. Multiple links of this type on the same page are numbered sequentially.

[1]
Bare external link
https://mediawiki.org

URLs beginning with "http://" and "https://" are automatically linked, even when no brackets are used.

<nowiki>https://mediawiki.org</nowiki>
https://mediawiki.org
Protocol-relative external link
[//en.wikipedia.org Wikipedia]

[//en.wikipedia.org //en.wikipedia.org]

The link will be HTTP or HTTPS depending on the protocol of the page currently being viewed (which could be different for different users). This is only supported inside of square brackets [ ]. Using "//en.wikipedia.org" by itself does not result in a link.

External links to internal pages

To add a link to a page on the same wiki using URL query parameters, you may need to use external link syntax.

Descrição You type You get
External link to the current page's edit page
[https://www.mediawiki.org/w/index.php?title=Help:Links&action=edit Edit this page]

[{{fullurl:{{FULLPAGENAME}}|action=edit}} Edit this page]

External link to the current page's edit page, and styled to look like an internal link
<span class="plainlinks">[https://www.mediawiki.org/w/index.php?title=Help:Links&action=edit Edit this page]</span>

The plainlinks class can be used in cases where you want an external link to look like an internal one, by suppressing the icon that normally appears after it.

External link icons

Some MediaWiki installations are set up to use special icons to denote external links to specific file types or using specific protocols. None of these special icons are enabled here on MediaWiki.org, but we present them here for the sake of completeness.

Interwiki links

Interwiki links are internal-style links to other websites (which do not have to be wikis, despite the name). For example, you can link to the article http://en.wikipedia.org/wiki/Sunflower by typing [[wikipedia:Sunflower]] or, on this wiki, the shorter [[w:Sunflower]]. Both will result in a link wikipedia:Sunflower. This works because by default MediaWiki configures wikipedia: as an "interwiki prefix" that turns into http://en.wikipedia.org/wiki/ when used inside [[ ]]. (It may not work if the admin of your wiki has changed the setting.) Unlike internal links, interwiki links do not use page existence detection, so an interwiki link will appear blue even if the page does not exist on the remote wiki.

Similar to internal page links, you can create piped links, with alternate link label, e.g. [[wikipedia:Sunflower|big yellow flower]] is the link big yellow flower and [[wikipedia:Sunflower|]] is the link Sunflower.

Basically, interwiki links are abbreviations for commonly-used longer external links. A very similar link could be created as [http://en.wikipedia.org/wiki/Sunflower big yellow flower].

More details are at Manual:Interwiki and m:Help:Interwiki linking. Your wiki may have a Special:Interwiki page listing the interwiki prefixes it supports; here is the default interwiki list. You can edit the interwiki table on your site.

Interlanguage links

If your wiki has other language versions, you may find “interlanguage links” in the sidebar, just below toolbox in a section titled “in other languages.”

In wiki markup an interlanguage link looks very much like an interwiki link, but behaves similarly to a category link in that it is rendered in a special way. While category links appear in a special list at the bottom of the page (usually), interlanguage links appear in a special list in the sidebar of the page (or elsewhere, depending on the wiki's configuration and the skin used).

The purpose of interlanguage links is to link pages on the same topics in different languages. To create an interlanguage link, type [[language prefix:page name]] anywhere in the page (preferably at the bottom, like category links); the language prefix is the prefix specified at your wiki for the other language version (typically the ISO 639-1 language code). The interlanguage link is unilateral, it does not point back from that page in the other language. For that purpose, an equivalent back-link needs to be placed there as well. It does not work like the "Edit links" in the languages section of Wikipedia-language versions. But it can be used across all name spaces, including 'User:' to point to ones other profiles in other languages.

If you want to make the interlanguage link appear at a specific place in the content of the page rather than in the sidebar, add a colon before the language prefix:

[[:en:Sunflower]]en:Sunflower

When a link is both interwiki and interlanguage, the order is wikipedia:en:Sunflower.

For more information, see m:Help:Interwiki linking#Interlanguage links.
