For basic information about wiki-markup in general, see [[Help:Editing]].'' <!-- edit 7/7: kept familiar link, but corrected topic --> With MediaWiki it is not possible to code hyperlinks using [[w:HTML|HTML]]. Instead there are three general types of hyperlinks, each with associated [[w:Cascading Style Sheets|CSS formatting]] to distinguish them: wikilinks, interwiki links, and external links. Besides linking, each provides important additional features specific to wikis, such as automatic broken-link detection for wikilinks, and automatic numbering of external links when used as references. == Wikilinks == A '''wikilink''' is an [[w:internal link|internal link]] to another page or page-section within the same [[w:wiki|wiki]]. <!-- edit 7/7: old moved up, new from below -->MediaWiki automatically checks if the target of a wikilink exists ("[[Help:Page existence|existence detection]]"). If the page doesn't exist, the link leads instead to the editing screen, and it is assigned the class "new". Such wikilinks are nicknamed "red links" because they are colored red in the default stylesheet on a default installation of MediaWiki. "Red links" are useful in determining the current status of the page (created or not created), create links to future pages, and facilitate and encourage creation of new pages. Also, through "What links here" applied to the non-existing page they provide indirect links to other pages with the same red link. A link to a non-existing page in the MediaWiki namespace for an existing [[help:system message|system message]] counts as a link to an existing page. === Syntax === MediaWiki defines a wikilink as a closed set of inward facing square bracket pairs '<nowiki>[[ ]]</nowiki>'. The link target is the sequence of characters immediately following the first bracket pair until pipe '|' or the opposing bracket pair ']]' is encountered (read from left to right). The link target can be another page on the wiki, a section on the same page as the link, or a section on another page on the wiki. * Inter-page links: Links of the form <code><nowiki>[[page_name]]</nowiki></code> link to the page that exactly matches that "page_name". * Intra-page links: Links of the form <code><nowiki>[[#link_name]]</nowiki></code> link to the first section on that same page, that has a heading (or anchor -- see [[#Anchors|below]]) which exactly matches that "link_name". * Inter-page "intra" links: Links of the form <code><nowiki>[[page_name#link_name]]</nowiki></code> link to the matching section of the matching page, see [[Help:Section#Section_linking|section linking]]. The wikilinks syntax also includes various formatting-options to control how a link and its visible text appear. <!-- TEMPLATE FOR ADDITIONS TO SYNTAX TABLE: --> <!-- = = = = = = = = = = = = = = = = = = = = = = = = = = = = = --> <!-- {{wikilink_syntax_tbl|[[LINK]]|= --> <!-- |<nowiki>[[LINK]]</nowiki>|= --> <!-- |TARGET|= --> <!-- |DESCRIPTION}} --> <!-- = = = = = = = = = = = = = = = = = = = = = = = = = = = = = --> <!-- --> <!-- --> {| class="wikitable" style="width:95%" !colspan="5" align="left"|Basic Wikilink Syntax {{wikilink_syntax_tbl|''Result''|''Code''|''Target''| ''Description'' }} {{wikilink_syntax_tbl|[[a]]|= |<nowiki>[[a]]</nowiki>|= |a|= |The simplest wikilink}} {{wikilink_syntax_tbl|[[a b]]|= |<nowiki>[[a b]]</nowiki>|= |a b|= |Multiple words}} {{wikilink_syntax_tbl|[[a b|c d]]|= |<nowiki>[[a b|c d]]</nowiki>|= |a b|= |Link targets 'a b' but displays 'c d' *}} {{wikilink_syntax_tbl|[[a b]]c|= |<nowiki>[[a b]]c</nowiki>|= |a b|= |The link label is the link target, with its last word extended to a longer word}} {{wikilink_syntax_tbl|<nowiki>[[a]]</nowiki>|= |<nowiki><nowiki>[[a]]</nowiki></nowiki>|= |&Oslash;|= |Text is displayed as typed without the properties of a link}} {{wikilink_syntax_tbl|[[a (b)|a]]|= |entered: <nowiki>[[</nowiki>a (b)&#124;]],<br> converted to: <nowiki>[[a (b)|a]]</nowiki>|= |a (b)|= |A pipe '&#124;' immediately before the closing bracket pair ']]' creates a piped link which hides the part in parentheses when it is displayed *,***}} {{wikilink_syntax_tbl|[[a, b|a]]|= |entered: <nowiki>[[</nowiki>a, b&#124;]],<br>converted to: <nowiki>[[a, b|a]]</nowiki>|= |a, b|= |A pipe '&#124;' immediately before the closing bracket pair ']]' creates a piped link which hides the comma and what follows when it is displayed *,***}} {{wikilink_syntax_tbl|[[w:a|a]]|= |entered: <nowiki>[[</nowiki>w:a&#124;]],<br>converted to: <nowiki>[[w:a|a]]</nowiki>|= |w:a|= |A pipe '&#124;' immediately before the closing bracket pair ']]' creates a piped link which hides the first prefix of the link when it is displayed *,**,***}} {{wikilink_syntax_tbl|[[w:a (b)|a]]|= |entered: <nowiki>[[</nowiki>w:a (b)&#124;]],<br>converted to: <nowiki>[[w:a (b)|a]]</nowiki>|= |w:a (b)|= |A pipe '&#124;' immediately before the closing bracket pair ']]' creates a piped link which hides the first prefix of the link and the part in parentheses when it is displayed *,***}} {{wikilink_syntax_tbl|[[mediawiki:1movedto2]]|= |entered: <nowiki>[[</nowiki>mediawiki:1movedto2&#124;]]|Mediawiki:1movedto2}} {{wikilink_syntax_tbl|[[mediawiki:1movedto3]]|= |entered: <nowiki>[[</nowiki>mediawiki:1movedto2&#124;]]|Mediawiki:1movedto2}} |} <!-- basics (above) & tricks (below) are really separate topics --> {| class="wikitable" style="width:95%" <!-- id added for anchor demo below --> !colspan="5" align="left" id="Wiki-link Tricks"|Wikilink Tricks & Demos {{wikilink_syntax_tbl|''Result''|''Code''|''Target''| ''Description'' }} {{wikilink_syntax_tbl|[[a|b|c]]|= |<nowiki>[[a|b|c]]</nowiki>|= |a|= |The wiki markup treats the second pipe '&#124;' as regular text *}} {{wikilink_syntax_tbl|[[a|b]]c|= |<nowiki>[[a|b]]c</nowiki>|= |a|= |'c' is appended to the end of the link text, targets 'a' -- (Good for adding a plural-'s') *}}<!-- hint to encourage space-saving --> {{wikilink_syntax_tbl|a[[b]]|= |<nowiki>a[[b]]</nowiki>|= |b|= |'a' immediately precedes the link text but is not included}} {{wikilink_syntax_tbl|[[a]]<nowiki>b</nowiki>|= |<nowiki>[[a]]<nowiki>b</nowiki></nowiki>|= |a|= |'b' immediately follows the link text but is not included}} {{wikilink_syntax_tbl|[[a]]''b''|= |<nowiki>[[a]]''b''</nowiki>|= |a|= |Using double apostrophes <nowiki>''</nowiki> around 'b' to make it italicized excludes it from the link text}} {{wikilink_syntax_tbl|[[a]]'''b'''|= |<nowiki>[[a]]'''b'''</nowiki>|= |a|= |Using triple apostrophes <nowiki>'''</nowiki> around 'b' to make it bold excludes it from the link text}} {{wikilink_syntax_tbl|[[a|b]]c<nowiki>d</nowiki>|= |<nowiki>[[a|b]]c<nowiki>d</nowiki></nowiki>|= |a|= |Translates like <nowiki>[[a|bc]]<nowiki>d</nowiki></nowiki> *}} {{wikilink_syntax_tbl|[[a]][[b]]|= |<nowiki>[[a]][[b]]</nowiki>|= |a , b|= |Two links next to each other, looks like [[ab]] when not hovered over with a [[w:cursor (computers)|cursor]]}} |} <nowiki>*</nowiki> Links with parameters (the link name) are said to be "piped" because of the pipe symbol used.

Attempting to link normally will place the image on the page, add the page to the category and create an interlanguage link at the edge of the page. This can be prevented by prefixing a colon, which escapes the specific syntax. For example, <code><nowiki>[[:Category:Help]]</nowiki></code>, <code><nowiki>[[:fr:Help:Link]]</nowiki></code>, and <code><nowiki>[[:File:Mediawiki.png]]</nowiki></code>. In the case of a link to a local, non-existing, dynamically generated image description page of an image on Commons, this page is counted as existing for links on pages, e.g. [[:File:Cow-on pole, with horns.jpeg]], but not for links in edit summaries and logs. The existence of an internal link from a page to an existing or non-existing page is recorded in the [[pagelinks table]]. ===Stub feature=== A wikilink to an existing page will be in class 'stub' if the page is in the main namespace, it is not a redirect, '''''and''''' the number of bytes of the wikitext is less than the "threshold for stub display" set in the [[Help:Preferences|user's preferences]]. This allows users to immediately identify links to very short pages that probably need to be expanded. Alternately, a user may set a very high threshold to achieve any of the following: * Identify links to very large pages. However, the criterion is the size of the wikitext; possible inclusion of templates and images can make the rendered page large, even if the amount of wikitext is small. * Determine at a glance whether a link leads to the main namespace or not. However, this does not take into account ''redirects'' to the main namespace (even if the redirect itself is in the main namespace). * Identify links to redirects, for clean-up work such as bypassing redirects. However, section linking to a "stub" does not work. Although this is normally a minor issue, this may cause problems with users who set a very high threshold. == Interwiki links == {{main|Help:Interwiki linking}} An '''[[Help:Interwiki linking|interwiki link]]''' links to a page on another website. Unlike the name suggests, the target site need not be a wiki, but it has to be on the [[m:Interwiki map|interwiki map]] specified for the source wiki. These links have the associated CSS class "extiw". These are in the same form as wikilinks above but take a prefix which specifies the target site. For example, on Wikimedia projects (except Wikipedias) and many other wikis <code><nowiki>[[wikipedia:Main Page]]</nowiki></code> links to the main page of the English Wikipedia. The prefix can be hidden using the same piped syntax as wikilinks. An interwiki can also link to a section or other anchor, see [[Help:Section#Section_linking|section linking]]. === Interwiki links back to same project === Although interwiki links can be used to point to a wiki from itself, this is not generally recommended. MediaWiki does not detect whether or not the target page of an interwiki list exists, so there is no special formatting and the link is always to the view page. Further, MediaWiki does not check if the page is linking to itself. A [[Help:Self link|self wikilink]] is bolded (like [[{{NAMESPACE}}:{{PAGENAME}}]]), whereas a self interwiki link is normal ([[m:{{NAMESPACE}}:{{PAGENAME}}]]). Pros: * A copy of the wikitext on a sister project may still point to the same page. Sometimes two prefixes are needed for that purpose, e.g. [[w:de:a]]. Cons: * Link has non-standard appearance * No existence-detection for target page == External links == External links use absolute URLs to link directly to any webpage. These links have the associated CSS class "external". External links are in the form <code><nowiki>[http://www.example.org link name]</nowiki></code> (resulting in [http://www.example.org link name]), with the link name separated from the URL by a space. Links without link names will be automatically numbered: <code><nowiki>[http://www.example.org]</nowiki></code> becomes [http://www.example.org]. Links with no square brackets will be displayed in their entirety: http://www.example.org. To show a URL without link use e.g. <code><nowiki>&lt;nowiki>http://www.example.org&lt;/nowiki></nowiki></code> giving <nowiki>http://www.example.org</nowiki>. Unlike in the case of internal links, characters immediately after the closing bracket are not added to the link label: <nowiki>[http://www.example.org a]s</nowiki> gives [http://www.example.org a]s. See [[Help:URL#URLs in external links|URLs in external links]] for more detailed information. ===E-Mail Links=== Links to an E-mail address work the same way that external links do, except they require the prefix <code>mailto:</code>. E-mail links are in the form of <code><nowiki>[mailto:anyone@example.org address name]</nowiki></code> (resulting in [mailto:anyone@example.org address name]), with the link name separated from the address by a space. Addresses without names will automatically be numbered: <code><nowiki>[mailto:anyone@example.org]</nowiki></code> becomes [mailto:anyone@example.org]. Addresses without square brackets will not be rendered as link, e.g. anyone@example.com. It's possible to make CC with <code><nowiki>[mailto:anyone@example.org?cc=anyone2@example.org address name]</nowiki></code> (resulting in [mailto:anyone@example.org?cc=anyone2@example.org address name]). === Same project, special page === External links support various special optional URL parameters in their linking-code. These allow links directly to the edit history of a page, to a page in edit view, a diff of two versions, et cetera. They can also be used to create a [[Help:Navigational image|navigational image]]. <!-- edit 7/7: block moved down --> For portability, use "fullurl" where the URL should depend on the project. ===Arrow icon=== MonoBook skin produces an arrow icon after every external link. This can be suppressed with class="[[mw:Plainlinks|plainlinks]]": *<code><nowiki>[http://a a]</nowiki></code> gives [http://a a] *<code><nowiki><</nowiki>span class="plainlinks"><nowiki>[http://a a]</</nowiki>span></code> gives <span class="plainlinks">[http://a a]</span> With some special code on [[MediaWiki:Common.css]] such as on [[m:MediaWiki:Common.css]], external links to PDF files have their own icon [[File:Icons-mini-file_acrobat.gif]]. On this site with your current settings http<nowiki>://a.pdf</nowiki> gives http://a.pdf . ===Skipping a number=== To skip a number in the automatically numbered external links (for whatever reason), use e.g. <nowiki><span style="display:none">[http://a]</span></nowiki>: [http://meta.wikimedia.org]<span style="display:none">[http://a]</span>[http://meta.wikimedia.org]. Note that a false condition of a ParserFunction, or a template like {{links-small|template|x0}} does not work, because counting the links is done after expansion of templates and parser functions. === Linksearch === [[Special:Linksearch]] (an extension installed on Wikimedia wikis, [http://svn.wikimedia.org/viewvc/mediawiki/trunk/extensions/LinkSearch]) finds all pages linking to a given URL. Using the [[mw:externallinks table|externallinks table]] it provides for a given external link pattern a list of source page names on the wiki concerned (linked) with for each the full link target (also as a link). One can either search all namespaces or a selected one. A leading wildcard '''*''' can be used to search links to a whole [[w:top-level domain|top-level domain]] (e.g. [http://en.wikipedia.org/wiki/Special:Linksearch?title=Special%3ALinksearch&target=*.nl]), or a [[w:second-level domain|second-level domain]] (e.g. [http://en.wikipedia.org/wiki/Special:Linksearch?title=Special%3ALinksearch&target=*.ns.nl]), etc. In the case that a full domain name is specified, one can additionally specify the rest of the URL, or the first part of that (a wildcard at the end is implied), e.g. [http://meta.wikimedia.org/wiki/Special:Linksearch?title=Special%3ALinksearch&target=en.wikipedia.org/wiki/Portal]. Remarks: *Do not put "http://". *The colon in the URL may cause the program return no results. *A MediaWiki page name in a URL has underscores instead of spaces. Also the URL specified in Linksearch requires writing underscores. *Even if multiple URLs lead to the same target, with regard to capitalisation, multiple underscores, and using "index.php" or not, Linksearch is case-sensitive and also does not find alternatively written URLs. Therefore, when creating an external link, for optimal use of Linksearch, use a canonical form for the URL. In particular, if after following a link the address bar shows a modified URL, change the URL in the link to that. *The list is {{ml|Help:Alphabetic_order|alphabetic}} in the URL. Note that an underscore, unlike a blank space, is alphabetically positioned between "Z" and "a". ===Backlinks=== <!-- edit 7/7: moved from above --> Commonly, a link to a normal page on the same project is in internal link style. An advantage is the existence detection. Also, if some links are in internal and some in external link style, we need both "What links here" and Linksearch for finding all backlinks. However, especially for a link to a section or explicitly-set anchor, one could put an internal link and also, with CSS style "display=none", an external link, to provide backlinks. External link style is also superior to interwiki link style. The URL specified for Linksearch can even contain an anchor (see below), or the first part of an anchor. Therefore Linksearch can find backlinks of sections and explicit anchors. In this regard external links are even superior to internal links. We can combine the advantages of internal and external link style by putting both, but hiding the external links: <nowiki><span style="display:none">http://...</span></nowiki> <!-- edit 7/7: rearranged and expanded --> == Anchors == {{seealso|Template:Anchor}} ===Linking to anchors=== Links of the form <code><nowiki>[[#anchor_name]]</nowiki></code> will link to the first anchor on the page matching that "anchor_name", usually the first identical section heading. An #anchor_name can also be appended to the page name in any type of link, thus linking to the first identical section heading (or anchor) of the '''named''' page: <code><nowiki> [[Help:Editing#Links]], [[m:Help:Editing#Links]], </nowiki></code> <code><nowiki> http://meta.wikimedia.org/wiki/Help:Editing#Links </nowiki></code> ===Automatic anchors=== Section headings automatically act as anchors, with the heading text as the "anchor_name". In the case of multiple sections with identical headings, the anchor name of each has "_2", "_3", etc. appended, starting from the second occurrence. The anchor [[#toc]] links to the table of content of the page, unless there is a section titled "toc". ===Manual anchors=== Manually-set anchors are useful for linking to "unlinkable" things like a table (title or cell), a section of plain text, etc. For example, in the [[#Wiki-link Tricks|Wikilink Tricks & Demos table]] above, though the "Wikilink Tricks & Demos" title-text appears like a (minor) heading, it is not, and the otherwise perfectly normal wikilink <code><nowiki>[[#Wikilink Tricks & Demos]]</nowiki></code> will not work. There are a number of ways to set an anchor at an arbitrary position: <!-- tested 7/7 --> * On some wikis, a [[template]] called "anchor" exists, e.g. {{links-small|template|anchor}} and {{links-small|w|template|anchor}}, providing a simple, standardized method for that wiki. * Generic anchor: <code><nowiki><span id="anchor_name">some text</span></nowiki></code>. For a hidden anchor, omit the text. * Manual HTML headings (discouraged): <code><nowiki><h2>How to Edit</h2></nowiki></code>. Text is anchor_name.<!-- demo of this code creates useless entry in TOC --> * In some cases, inserting an HTML-like ID attribute into an (existing) Wiki-element. For example, from the [[#Wiki-link Tricks|Wikilink Tricks & Demos ]] table above:<br> <code><nowiki> !colspan="5" align="left" id="Wiki-link Tricks"|Wikilink Tricks & Demos </nowiki></code> * The reserved name <code><nowiki>[[#top]]</nowiki></code> always links to the [[#top|top of a page]]. See also [[Help:Section#Section_linking]]. ===Linksearch anchors=== As mentioned above, if external link style is used, e.g. [http://meta.wikimedia.org/wiki/Help:Section#Section_linking], we can use [[Special:Linksearch]]: [http://meta.wikimedia.org/wiki/Special:Linksearch?title=Special%3ALinksearch&target=meta.wikimedia.org/wiki/Help]. Since Linksearch allows specifying the first part of an anchor, it is useful, if anchor names are numerical or have a numerical end, to use leading zeros. Otherwise, when searching for links to e.g. "1", we also get links to "10", etc. This is e.g. applied in [[w:Portal:Current events/DateHeader2]]. More generally, if there are anchors "a" and "ab", it may or may not be desired that a search for links to "a" also gives links to "ab"; if not, use an anchor "_a". ===Index-style anchors=== If anchor names have multiple components, it is useful to put the most significant component first, e.g. if anchors indicate months or dates, we could have the format YYYY-MM, or YYYY-MM-DD, or in a year page MM-DD (see also [http://en.wikipedia.org/wiki/Calendar_date#Big_endian_forms.2C_starting_with_the_year]), with leading zeros (see also [http://meta.wikimedia.org/wiki/Help:Date_formatting_and_linking#Link_to_date_content_other_than_required_for_autoformatting]). This applies also for page names, but since these are highly visible, as opposed to anchors, other considerations play a role too. In the case of sections, if for link targets another naming scheme is desired than for display of section headings, explicitly put anchors instead of using section names. This is applied in [[w:Portal:Current events/DateHeader2]], where the use in links of the names of explicitly put anchors is enforced by using pseudo sections, with displayed headings that cannot be used as anchors. ===Anchors in external links (anchorencode)=== In an external link, an anchor can be created conveniently with the parser function [[anchorencode]], for example, <tt><nowiki>"{{anchorencode:Anchors in external links (anchorencode)}}"</nowiki></tt> gives "{{anchorencode:Anchors in external links (anchorencode)}}" which can be used to form the link {{fullurl:{{PAGENAME}}}}#{{anchorencode:Anchors in external links (anchorencode)}} ==Subpage feature== MediaWiki has a [[w:subpage|subpage]] feature, although activation depends on project and namespace. If activated, the following applies (if not, "A/b" is just a page with that name). A [[w:en:tree structure|tree structure]] of pages is established by using forward slashes in pagenames: A/b is a child of A, hence A is a parent of A/b; also A/b/c is a child of A/b; while A/a, A/b, and A/c are siblings. At the top of the subpage body links to all ancestor pages are shown automatically, without any corresponding wikitext. The links show up even if the parent page does not exist, but the sequence of ancestors stops before any non-existing ancestor page (e.g., if the grandparent page does not exist, the parent page is not shown either). Like most letters of a page name, the first letter after the slash is case-sensitive; "/subpage" and "/Subpage" are different pages. [[Help:What links here|What links here]] and [[Help:Related changes|Related changes]] ignore these automatic links. In the namespace where the subpage feature is activated, any slash in a page name causes a subpage structure, even if unintended. ===Variables=== On page A:B/c/d, where A is a namespace with the subpage feature enabled, <nowiki>{{BASEPAGENAME}}</nowiki> gives B/c and <nowiki>{{SUBPAGENAME}}</nowiki> gives d === Relative links === Inside a subpage hierarchy the following relative links can be used: * <nowiki>[[../]]</nowiki> links to the parent of the current subpage, e.g., on A/b it links to A, on A/b/c it links to A/b. * <nowiki>[[../../]]</nowiki> links to the grandparent of the current subpage, e.g., on A/b/c it links to A. * <nowiki>[[../s]]</nowiki> links to a sibling of the current subpage, e.g., on A/b, it links to A/s. * <nowiki>[[../../s]]</nowiki> links to an "uncle" of the current subpage, e.g., on A/b/c, it links to A/s. *<nowiki>[[/s]]</nowiki> links to a subpage, e.g. on A it is the same as <nowiki>[[A/s]]</nowiki>. Because of this, linking from a namespace where the subpage feature is enabled to a page in the main namespace with a name starting with "/", requires a workaround: put a colon before the pagename. Linking to an anchor of an ancestor does not work; attempting that gives a link to a page with the name consisting of the name of the ancestor followed by "/". Relative links still work if all pages of a tree are renamed according a name change of the root, including making it a child of a new root. See also [[w:Wikipedia:Subpages]], and the example pages [[m:Link/a/b]] and [[m:Help:Link/a/b]]. The subpage feature works in both namespaces. === Subpage activation === Wikipedia has this feature activated in all talk namespaces and the user and project namespace. The Meta-Wiki also has it in the main namespace. The default is set in [[mw:Help:Configuration settings|DefaultSettings.php]][http://cvs.sourceforge.net/viewcvs.py/wikipedia/phpwiki/newcodebase/DefaultSettings.php?rev=1.21&view=markup]. As of revision 1.21, the following namespaces have it activated by default: Special, Main talk, User and User_talk, Meta_talk, and Image_talk. Settings per project are changed in [[LocalSettings.php]][http://cvs.sourceforge.net/viewcvs.py/wikipedia/phpwiki/newcodebase/LocalSettings.php?rev=1.25&view=markup]. See also {{mlmw|Manual:$wgNamespacesWithSubpages}}. === User space === Subpages of a user page (<code><nowiki>[[User:Username/Subpage]]</nowiki></code>) are considered to be in that user's "user space". == Character conversion == In accordance with the rules explained in [[Help:Page name]], conversions are automatically made to [[Help:Special characters|non-literal characters]] in wiki and interwiki links. For example, "<code><nowiki>[[Help:Page%20name]]</nowiki></code>" becomes "[[Help:Page name]]". However, the opposite is true for external links; literal characters are converted into non-literal characters. For example, most browsers will convert ".../wiki/!" to ".../wiki/%21". A code like %70 in a redirect disables it, although the link works from the redirect page. For a redirect that works, the redirect page shows the canonical form of the target, unlike its preview page, which renders the link in the usual way. == Miscellaneous == === Additional effects of links === *[[Help:Related changes|Related changes]] *[[Help:What links here|Backlink]]s, [[Help:Linksearch|Linksearch]] *[[Help:Date formatting feature|Date formatting]] * Using a space after the pipe syntax (<nowiki>[[Main page| ]]</nowiki>) produces (perhaps depending on the browser) a space only, not a link ("[[Main page| ]]"), but it is treated as a link for the "what links here" feature. === "Hover box" on links === On some browsers, holding the cursor over link will show a hover box containing the text of the link's HTML title attribute. MediaWiki sets this to the target page name (without the possible section indication) if it's a wikilink (the {{msg|red-link-title}} if the page does not exist), the page name with prefix if it's an interwiki link, and the URL if it's an external link. This can be switched off in the [[Help:Preferences|user preferences]]. The browser may also show similar info, but with the possible section indication, in the status bar. For these effects a piped link is useful even if it not followed to the target; for example, for displaying the meaning of an acronym (e.g. [[neutral point of view|NPOV]]) or any other remark. It is possible to produce a hover box without a link, see {{links-small|template|H:title}}. It is also possible to change the contents of the hover box, using markup similar to <code><nowiki>[[Link title|<span title="hoverbox">Display text</span>]]</nowiki></code>, e.g. {{xpdplain|[|[w:foot (length){{!}}<|span title{{=}}"30.48 cm">ft<|/span>]]}} ===Links from a page=== With the [[m:query|Query API]] the links from page ''pagename'', sorted by namespace, and for each namespace alphabetically, are given by <nowiki>{{SERVER}}{{SCRIPTPATH}}</nowiki>/query.php?what=links&titles=''pagename'' , e.g. {{SERVER}}{{SCRIPTPATH}}/query.php?what=links&titles={{FULLPAGENAME}} . === Linking to a page from an image === It is possible to use images as links to other pages.
