Esistono cinque tipi di collegamenti ipertesto in MediaWiki:

1. Collegamenti interni ad altre pagine dello stesso wiki (comunemente chiamati "wikilinks")
2. Collegamenti esterni a pagine di altri siti web
3. Collegamenti esterni a pagine interne nello stesso wiki
4. Collegamenti Interwiki ad altri siti web che utilizzano prefissi speciali registrati in anticipo
5. Collegameti interlinguistici ad altri wiki registrati come versioni linguistiche diverse della wiki corrente

Si noti che questo elenco non include la categoria dei collegamenti e i collegamenti di file, che vengono utilizzati per posizionare le pagine in categorie e visualizzare immagini o altri file multimediali, rispettivamente.

Collegamenti interni

Per creare un cosiddetto link interno a una pagina sullo stesso wiki (un "wikilink"), usa il doppio markup del wiki delle parentesi quadre, [[come questo]]. Quando si visualizzano in anteprima o si salvano le modifiche, verrà visualizzato un collegamento che può essere seguito alla pagina di destinazione. Se la pagina esiste il collegamento viene visualizzato in blu (come la parola "crea" nella prima frase di questo paragrafo); se la pagina non esiste, il link appare rosso (quindi il [[come questo]] è effettivamente reso come questo). Si noti che i colori potrebbero essere diversi se lo schema dei colori del wiki è stato modificato rispetto all'impostazione predefinita. Il "Collegamento rosso" significa che la pagina è mancante (indipendentemente dal fatto che sia effettivamente rossa) di solito consente all'utente di creare la pagina.

Per contrassegnare qualsiasi stringa di testo arbitraria (non necessariamente un titolo di pagina) come collegamento, utilizzare un carattere "barra verticale" o "pipe", come questo: [[Help: Categories | link di categoria]] < The first letter of the link target is usually not case-sensitive (unless the wiki is configured otherwise), meaning links can be capitalized or not (so [[How to contribute]] and [[how to contribute]] are equivalent). However, the case of every ''subsequent'' letter must match the target page exactly (so [[How to contribute]] and [[How To Contribute]] are ''not'' equivalent). Spaces in the page title may be represented as underscores (so [[How to contribute]] and [[How_to_contribute]] are again equivalent), but using underscores in links will make them visible in the page text (but this can be prevented by using a "pipe"). If the page title you are linking to is that of the page you are editing, the result is not a hyperlink at all but simply bold text (for example, on this page the markup <code><nowiki>[[Help:Links/it]] gives the result Help:Links/it). If you're trying to create a wikilink to the current page, you probably want to link to a specific section or to an anchor within the page; see the examples below.

MediaWiki uses the pagelinks database table to keep track of internal wikilinks.

Collegamenti esterni

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.

Descrizione	You type	You get
External link with specified link text	[https://mediawiki.org MediaWiki]	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.	https://mediawiki.org
Avoiding auto-linked URLs	<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.	Wikipedia //en.wikipedia.org
External link to the current server	https://{{SERVERNAME}}/pagename	https://www.mediawiki.org/pagename
External link to other host passing the pagename	https://google.com/search?q={{PAGENAMEE}} See also: URL encoded page names, PAGENAMEE encoding	https://google.com/search?q=Links
Mailto link	[mailto:info@example.org email me]	email me
Mailto named with subject line and body	[mailto:info@example.org?Subject=URL%20Encoded%20Subject&body=Body%20Text info]	info
Custom URI	[skype:echo123 call me] Any URI you wish to add needs to be first declared through $wgUrlProtocols . (This example is not enabled on MediaWiki.org)	[skype:echo123 call me]

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.

Descrizione	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] See also Help:Magic_words#URL_data and External links above.	Edit this page 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.	Edit this page

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 https://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 https://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 [https://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 altre lingue.”

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.

Limits

An internal wiki link is limited by maximum page title size.
