Anchors, Internet Explorer 8.0 and w3c
I am not sure about this anchor links to jump to a section on the same site. It not work on mediawiki sites. But it work on w3c sites like http://www.w3.org/TR/html401/about.html, therefore what's the problem? --Lastwebpage 09:14, 30 August 2008 (UTC)

How to make mailto link do First Last 
I have not figured out how to get MediaWiki to let me do this. I tried [mailto:First%20Last%20] [mailto:%20First%20Last] [mailto:First%20Last ] [mailto: First%20Last] [mailto:foo@bar.com First%20Last] [mailto:foo@bar.com%20First%20Last First Last] [mailto:%20First%20Last First Last] [mailto:First%20Last%20 First Last] None of these works.

This workaround is as close as I could come: [mailto:(First%20Last)%20foo@bar.com First Last]

Dave Yost 21:26, 2 September 2008 (UTC)


 * In this case  works and is displayed (as you wish) as [mailto:foo@bar.com First Last ]. The structure is generally the same as for normal external links:  . -- :bdk:  23:33, 2 September 2008 (UTC)


 * I think perhaps what Dave is after is for the mailto: to actually pass the recipient name to the mail program as well as the address. A standard html mailto: link (">) does do this in various clients, but is not actually compliant with [RFC1738]. Mediawiki insists on using the space to separate the link destination and link text ([mailto:An Example ] - hover to see "mailto:An" ) - which is actually "correct" behaviour.

How to link with a local file?
Hi there, does anyone know, how to link with a file on a local volume? e. g.  or   doesn't work. Thank you -Rob.

more problem with mailto - using 'subject' field
Is there a way to include subject fields and other options in a mailto link in mediawiki? The HTML syntax for mailto links would be text, but this obviously fails because any space in the subject field would be interpreted as the separator... and standard html doesn't work at all. Is there any workaround for this, or some feature of the software that I have overlooked? --89.207.208.9 11:02, 12 December 2008 (UTC) Carelesshx 11:03, 12 December 2008 (UTC)


 * You must use "%20" instead of " " (space). Example:  is displayed as [mailto:foo@bar?subject=a%20subject]. I also had problems with special characters (Latin), so I had to use the hexadecimal values of ISO-8859-1 (ISO Latin 1) character encoding preceded by "%". I don't know if the characters are displayed correctly for everyone, but it worked for me. Example:   is displayed as [mailto:foo@bar?subject=informa%E7%F5es&body=test] -- 201.76.26.103 23:53, 22 January 2009 (UTC)

Auto linking
Is there a good way to designate words or phrases that should automatically link to certain pages? For example if I have an auto-repair wiki and I want every occurence of the phrase "distributor cap" on any page to link to the "Distributor" page, is there a way to do this without manually assigning the link each time? --IP 13 January 2009

Internal Links in a new window
Does anyone know of a way (new syntax perhaps?) that allows for internal links to open up in another window? I prefer not to modify code that affects all internal links, only those that we want.

It is not possible with wiki code, as far as I know, but it can be done with JavaScript:

https://www.google.com/search?q=target=+_blank+javascript

You might find some easy copy-and-paste code at that search. When you find something you think may work for you, put it in your MediaWiki:Common.js. And, of course, report back the results of your research so others can benefit from it too. Badon (talk) 06:03, 12 April 2012 (UTC)

This can done but requires an extension. Install from here: https://www.mediawiki.org/wiki/Extension:LinkTarget As of this timestamp, example 3 on the linked page does what you want. Add the suggested lines to your LocalSettings.php file, then all your existing link tags should then open in a new tab. It can be overridden using the span class wrapper, which is also explained on that page. Polymath uk (talk) 13:36, 23 January 2023 (UTC)

Custom link title?
The default wikilink title is the target page title (this is undocumented). How do I specify a custom title that better matches the context? Example: at Bohm interpretation there is a wikilink to Copenhagen interpretation and the title is "Copenhagen interpretation". It would be much more informative to make the title "the state of every particle is described by a wavefunction". --Yecril 08:07, 19 October 2009 (UTC)

Link to "Special:Allpages" with the namespace parm set
We are using Mediawiki 1.8.2.

Showing links on message pages
I want to create an internal link (to a specific wiki page) on a message page (MediaWiki:Badaccess-groups). So, when the user sees that page they will get a link to a page (access restriction) explaining more. When I add the link I see access restriction (bold, link: correct). But when a user who does not have access sees the page they see access restriction i.e. it looks to them like the nowiki tags are present.

External links without icons

 * External links without icons - is that possible using some standard markup? I want to save some space while putting a bunch of useful links into my navigation bar.

List of prefixes for wikis registered in advance (to use in InterWiki links)?
Is there some list you can look in if you want to find the prefix to a specific wiki that is registered in advance (as it says in the section about Interwiki links), such as Wikipedia, Commons, Wikia or this site (MediaWiki)? That would be really useful, especially since I in fact don't know any way at all to find the prefix to a specific wiki. For example, now I would like to link an article on the OpenGL Wiki, but I can't use an Interwiki link since I don't know the prefix. —Kri 13:49, 12 July 2011 (UTC)

Are you sure it should be PAGENAMEE with two E's? Or should it be PAGENAME? Can someone check and correct this?? --TJRana 22:28, 1 January 2012 (UTC)


 * It is correct. That form does URL encoding.

Adding tel: link
Hi: I am trying to include tel: links into my MediaWiki installation. They should work just like a mailto:foo@foo.bar link, but for telephone numbers. So, they should look like tel:+1234567890. When used on a mobile device these tel: links are opened by the telephone application and can be called directly from the website.

I would like to have the following structure:

Phone: [tel:+1234567890 +1 (123) 456789-0]

I have been looking around the source files to locate the one which defines mailto links for example, but couldn't locate it.

Anyone of you got an idea how to accomplish this?

Thanks Tuluqaruk (talk) 08:26, 10 April 2012 (UTC)


 * I agree, this should be simple to do, but I don't know of a simple way to do it. However, there are 2 more complicated ways to do it. The simplest is probably with Extension:Widgets. Also, Extension:Semantic MediaWiki can do it with its built in telephone number type. I hope that helps. Badon (talk) 10:54, 10 April 2012 (UTC)


 * Easy enough, just add tel: to the list of allowed protocols. Add array_push( $wgUrlProtocols, "tel:" ); to your Localsettings.php.


 * That works. Thanks!  I added it to the $wgUrlProtocols array rather than use array_push (I assume either way would work).  Next step is automatically make phone numbers (and mailto: links) external links the same way http:// links are handled.  Anyone know how to do that?  Potrod (talk) 21:33, 15 July 2016 (UTC)

Initially thought them to be equivalent, but these are some different behaviours I have noticed on our wiki (in these examples 'uploaded file.txt' is an existing file (blue link) while 'not a valid file.txt' is not (red link)):


 * renders as  in blue (OK)
 * renders as  in red (OK)
 * renders as  in blue (OK)
 * renders as  in red (OK)
 * renders as  in blue (NOT OK - alternate text not displayed)
 * renders as  in red (OK)
 * renders as  in blue (OK)
 * renders as  in red (OK)

Is this the default behaviour? If so, I think it should be better documented somewhere.

How to write permanent anchor of sections?
With a hierarchy like this:

created
When people link to account.created, it would be Page#created_2, right?

But when there's something added in between, like this:

created
The anchor of account.created would then become #created_3, right? All the links to Page#created_2 before the change would now lead to the wrong section, that is category.created.

Is there any way to fix or work around this problem? Can we make the section anchor permanent once created? So new sections of the same title would have new anchors regardless of its location?

Link to search results

Handling of entities in page titles
I noticed the following while fiddling around with the Usain Bolt article on Wikipedia.

Markup:

Result:

Strangely the link still works, but the non-breaking spaces do not survive to the rendered link text (opposite in both regards to naive intuition).

It wouldn't be a bad thing if nbsp entity was defined as an alias for regular space in the page name, but the nbsps were preserved in the rendered link text. Either way, the handling of entities in link targets could be better documented. MaxEnt (talk) 02:15, 9 February 2017 (UTC)

Redlink Feature Request: Show "What links here?" for Redlinks
Not sure if this is the correct place for me to post this feature request. If not, please advise me on how to submit this in the correct place.

The feature request is that when clicking on a Redlink (which takes the user to the "Create page" view) the UI should show which pages link to the Redlink. This can make it easier for the user creating the page to find relevant information about the topic they're creating. This feature could also help identify Redlinks which might need disambiguation pages, if Redlinks with different meanings and usages point to the same page. — Preceding unsigned comment added by Mapmaker345 (talk • contribs) 21 December 2018
 * If you follow a redlink, the "Creating…" page already contains a link to "What links here" in the sidebar (just like any other regular page on the wiki). Not as prominent as you might wish, perhaps, but it's there. Feature requests like this require creating a new "task" at the Wikimedia Phabricator, since this would presumably require changes to the MediaWiki code. However, instead of trying to get the "What links here" page list itself to appear on the "Creating…" page, as you seem to be requesting, it might be more realistic to try to get a more noticeable link to "What links here" into the "You've followed a link to a page that doesn't exist yet" message that appears at the top of each "Creating…" page. That message is provided by MediaWiki:Newarticletext on each wiki. I believe Support is the place to suggest changes to the default (English) text for these kinds of messages (assuming you want it to affect "all" MediaWiki wikis). - dcljr (talk) 03:59, 22 December 2018 (UTC)

Link to file
I have a PDF file that I have uploaded to my MediaWiki instance. The link  links to the file detail page just fine. Is there a way to have a link that opens the file itself in a new tab (not just link to the file detail page)?

Link to a subpage of parent page for current page
In the example there is not a final slash but to achieve the desired result I think there has to be one. Like this: ../example2/ Seam.us (talk) 17:40, 3 August 2021 (UTC)

Allowed characters for the internal links
Please pay attention to the left side of the pipe and the right side of the pipe.

I couldn't find anything anywhere on the Internet. I didn't have time to learn the code myself. Viu54071 (talk) 08:07, 29 January 2023 (UTC)
