=== External links to internal pages ===
 
 
To add a link to a page on the same wiki using [[w:URI scheme | URL query parameters]], you may need to use external link syntax.

=== Format ===

For more help on images see [[http://www.mediawiki.org/wiki/Help:Images here]].
The following table shows the effect of all available formats.
 
  
{|class="wikitable plainlinks"
+
== SECTIONS  ==
|-
 
!Description
 
!You type
 
!You get
 
{{Help:Images/frame|frame=|ex=no format specified|float=no|inline=yes}}
 
{{Help:Images/frame|frame=border|ex='''border''' results in a very small gray border|float=no|inline=yes}}

|}
 
  
When the height of an image in thumbnail is bigger than its width (i.e. in portrait orientation rather than landscape) and you find it too large, you may try the option <code>upright</code>, which will try to adjust its size to a more desirable size by reducing the height instead of the width. The alternative is to specify the desired maximum height (in pixels) explicitly.
+
(May be referred to as Categories in this section)
  
Note that by writing <code>thumb={filename}</code>, you can use a different image for the thumbnail.
+
Categories, a software feature of MediaWiki, provide automatic indexes that are useful as tables of contents.
  
=== Size and frame ===
+
You can categorize pages and files by adding one or more '''Category''' {{#ifeq:Category|{{ns:category}}||'''({{ns:category}})'''}} tags to the content text. These tags create links at the bottom of the page that take you to the list of all pages in that category, which makes it easy to browse related articles.
Among different formats, the effect of the size parameter may be different, as shown below.
 
* For how it appears when its size is not specified, see [[#Format|Format]] section above.
 
* When the format is not specified, or only <code>border</code>ed, the size can be both reduced and enlarged to any specified size.
 
* In the examples below, the original size of the image is 400 × 267 pixels.
 
* An image with <code>frame</code> always ignores the size specification, the original image will be reduced if it exceeds the maximum size defined in user preferences.
 
* The size of an image with <code>thumb</code> can be reduced, but can not be enlarged beyond the original size of the image.
 
  
{|class="wikitable"

== Summary ==
|-
+
Each of the pages in the '''Category''' [[Help:Namespace|namespace]] represents a so-called '''category''', a grouping of related pages, and contains an index for the pages of its category. For example, this page belongs to "[[:Category:Help]]". If you open the "[[:Category:Help]]" page, you will see a link to this page there.
! Format !! Reduced !! Enlarged
 
{{Help:Images/size|frame=}}
 
{{Help:Images/size|frame=border}}
 
{{Help:Images/size|frame=frame}}
 
{{Help:Images/size|frame=thumb}}
 
{{Help:Images/size|frame=frameless}}
 
|}
 
  
=== Horizontal alignment ===
+
When a page belongs to one or more categories, these categories appear at the bottom of the page (or in the upper-right corner, depending on the [[Help:Preferences|skin]] being used).
Note that when using the <code>frame</code> or <code>thumb[nail]</code> formats, the default horizontal alignment will be <code>right</code>.
 
  
{|class="wikitable"
+
The category pages themselves contain 2 parts :
|-
+
* at their beginning, an optional part may contain text that can be edited, like any other page,
!Description
+
* at their end, an ever present, automatically generated, alphabetical list of all pages in that category, in the form of links. (In fact, in ASCII order. See [[Help:Special page]]).
!You type
 
!You get
 
{{Help:Images/frame|2=100px|frame=|ex='''no horizontal alignment specified''', or default alignment|inline=yes|float=no}}
 
{{Help:Images/frame|2=100px|frame=none|ex=specify horizontal alignment as: '''none'''|inline=no|float=no}}

{{Help:Images/frame|2=100px|frame=right|ex=specify horizontal alignment as: '''right'''|inline=no|float=yes}}
 
|}
 
  
=== Vertical alignment ===
+
To assign a category to a page, simply add the link "<nowiki>[[</nowiki>Category:''Category name'']]" to the page's wikitext. The usual place to add it is at the bottom of the page.
The vertical alignment options take effect only if the image '''is''' rendered as an inline element and '''is not''' floating. They alter the way the inlined image will be vertically aligned with the text present in the same block before and/or after this image on the same rendered row.
 
  
Note that the rendered line of text where inline images are inserted (and the lines of text rendered after the current one) may be moved down (this will increase the line-height conditionally by additional line spacing, just as it may occur with spans of text with variable font sizes, or with superscripts and subscripts) to allow the image height to be fully displayed with this alignment constraint.
+
To link a category page within a page as a normal wiki link (without adding the page to the category), prefix the link name with a colonFor example: <nowiki>[[</nowiki>:Category:Not in this category]]

To show the alignment result more clearly, the text spans are overlined and underlined, the line-height is increased to 200% of the font-height, the font-height is emphasized with a yellow background covering the line margins, and the full line-height is shown with a dark gray border; additionally images of different sizes are aligned, including one with an additional border that adds some pixels to its specified dimensions and slightly changes its vertical alignment:

New categories can be [[Help:Starting a new page|created]] before assigning any page to it, in the same way as any other regular page.

===Sort key===
<span style="background:#FFF;color:#000;text-decoration:overline"><u><del>text</del>

By default, a page is sorted within a category under the first letter of its full name ''including the namespace''. Also, MediaWiki groups accented characters separately from their unaccented version, so pages starting by À, Á, Ä, will be listed under separate headings, instead of under heading A.
'''text-bottom:''' [[File:Example.jpg|20px|text-bottom]] [[File:Example.jpg|40px|text-bottom]] [[File:Example.jpg|40px|border|text-bottom]]

A ''sort key'' specifies under which letter heading, and where in the category list, the page will appear. You can add a sort key by placing it inside the tag after a pipe character. For example, the tag below will add the page under heading "S".

Notes:
+
<nowiki>[[</nowiki>{{ns:category}}:'''''Name'''''|'''''Sort''''']]
# The "middle" vertical alignment position of the image (which is also the default) usually refers to the middle between the x-height and the baseline of the text (on which the vertical middle of the image will be aligned, and on which usually the text may be overstroke), but not to the middle of the line-height of the font-height that refers to the space between the "text-top" and "text-bottom" positions ; the font-height excludes:
 
#* the additional line separation spacing normally divided equally into two line-margins (here 0.5em, according to line-height set to 200%) above and below the font-height).
 
#* the additional line spacing which may be added by superscripts and subscripts.
 
# However, if the image height causes its top or bottom position to go above or below the normal full line-height of text, the middle position will be adjusted after the increasing the top and/or bottom line-margins so that the image can fit and align properly, and all images (including those with smaller heights) will be vertically centered on the adjusted middle position (for computing the effective line-height, the text of each rendered row with the larger font-height will be considered).
 
# The "text-top" and "text-bottom" alignment positions also excludes the extra line spacing added by superscripts and subscripts, but not the additional line-spacing defined by the line-height.
 
# The "top" and "bottom" alignment positions take into account all these extra line spacings (including superscripts and subscripts, if they are present in a rendered line span). When the image alignment constrains the image to grow above or below the normal line-spacing, and the image is not absolutely positioned, the image will cause the "top" and "bottom" positions to be adjusted (just like superscripts and subscripts), so the effective line-height between rendered lines of text will be higher.
 
# The "underline", "overline" and "overstrike" text-decoration positions should be somewhere within these two limits and ''may'' depend on the type and height of fonts used (the superscript and subscript styles may be taken into account in some browsers, but usually these styles are ignored and the position of these decorations may not be adjusted); so these decorations normally don't affect the vertical position of images, relatively to the text.
 
  
=== Stopping the text flow ===
+
Sort keys are case-sensitive, and spaces and other characters are also valid. The order of the sections within a category follows the Unicode sort order. The sort key does not change the page title displayed in the category.
On occasion it is desirable to stop text (or other inline non-floating images) from flowing around a floating image. Depending on the web browser's screen resolution and such, text flow on the right side of an image may cause a section header (for instance, <nowiki>== My Header ==</nowiki>) to appear to the right of the image, instead of below it, as a user may expect. The text flow can be stopped by placing '''<nowiki><br style="clear: both" /></nowiki>''' before the text that should start below the floating image.
 
  
All images rendered as blocks (including non-floating '''center'''ed images, '''left'''- or '''right'''-floating images, as well as '''framed''' or '''thumbnail'''ed floating images) are implicitly breaking the surrounding lines of text (terminating the current block of text before the image, and creating a new paragraph for the text after them). They will then stack vertically along their left or right alignment margin (or along the center line between these margins for '''center'''ed images).
+
==Creating a category page==
 +
Categories exist even if their page has not been created, but these categories are isolated from others and serve little purpose for organization or navigation.
  
=== Altering the default link target ===
+
A category is created by creating a page in the '''''Category:''''' namespace. A category page can be created the same way as other wiki pages (see [[Help:Starting a new page]]); just add "<code>{{ns:category}}:</code>" before the page title.
The following table shows how to alter the link target (whose default is the image description page) or how to remove it. Changing the link does not alter the format described in the previous sections.
 
  
{|class="wikitable plainlinks"
+
To avoid extra work, try searching within your wiki before creating a new category. The list of all categories can be found in "{{int:specialpages}}" in the "{{lcfirst:{{int:toolbox}}}}" box of the [[Help:Navigation#Sidebar|sidebar]].
|-
 
!Description

!You get

{{Help:Images/frame|2=link=|ex=no link (external or file page)}}
 
|}
 
  
'''Warning :'''
+
Unlike other wiki pages, it is not possible to rename (move) a category. It is necessary to create a new category and change the {{ns:category}} tag on every page. The new category will not have the older category's page history, which is undesirable if there are many revisions.
: The licencing requirements on your wiki may not allow you to remove all links to the description page that displays the required authors attributions, the copyrights statements, the applicable licencing terms, or a more complete description of the rendered image (including its history of modifications).
 
: If you change or remove the target link of an image, you will then have to provide somewhere else on your page an explicit link to this description page, or to display the copyright and author statement and a link to the applicable licence, if they are different from the elements applicable to the embedding page itself.
 
: Your wiki policy may restrict the use of the alternate link parameter, or may even enforce a prohibition of alternate link parameters for embedded media files (in which case, the link parameter will be ignored), or may only accept them after validation by authorized users or administrators.
 
  
== Rendering a gallery of images ==
+
==Managing the category hierarchy== 
 +
Categories may belong to other categories in a hierarchy. Since category pages are much like any other page, a {{ns:category}} tag may be added to the bottom of a category page.
  
=== Gallery syntax ===
+
It is a good idea to organize all categories into a hierarchy with a single top level category. The category structure can take the form of a tree with separate branches, but more often will have a graph structure. Generally, there should be a contiguous chain of parent-child links between each category and the top level category.  
It's easy to make a gallery of thumbnails with the <code><nowiki><gallery></nowiki></code> tag. The syntax is:
 
<nowiki><gallery></nowiki>
 
Image:file_name.ext|caption
 
Image:file_name.ext|caption
 
{...}
 
</gallery>
 
  
Note that the image code is not enclosed in brackets when enclosed in gallery tags.
+
==Linking to a category==
 +
To create a link to a category, use a leading colon before the category name (without this colon, the current page would be added to the category):
  
Captions are optional, and may contain wiki links or other formatting.
+
:<code><nowiki>[[</nowiki>:{{ns:category}}:Help]]</code> &rarr; '''[[:{{ns:category}}:Help]]'''
  
for example:
+
To change the link text, write the text inside the link tag after a pipe:
<nowiki><gallery></nowiki>
 
File:Example.jpg|Item 1
 
File:Example.jpg|a link to <nowiki>[[Help:Contents]]</nowiki>
 
File:Example.jpg
 
File:Example.jpg
 
File:Example.jpg| <nowiki>''italic caption''</nowiki>
 
File:Example.jpg|on page "<nowiki>{{PAGENAME}}</nowiki>"
 
</gallery>
 
is formatted as:
 
<gallery>
 
File:Example.jpg|Item 1
 
File:Example.jpg|a link to [[Help:Contents]]
 
File:Example.jpg
 
File:Example.jpg
 
File:Example.jpg|''italic caption''
 
File:Example.jpg|on page "{{PAGENAME}}"
 
</gallery>
 
  
=== Optional gallery attributes ===
+
:<code><nowiki>[[</nowiki>:{{ns:category}}:Help|Help category]]</code> &rarr; '''[[:{{ns:category}}:Help|Help category]]'''
The gallery tag itself takes several additional parameters, specified as attribute name-value pairs:
+
 +
[[Help:Redirects|Redirect pages]] that redirect to categories must also use the colon, otherwise they will be added to the category instead of redirecting.
  
<pre><gallery {parameters}>
+
==Renaming a Section==
{images}
 
</gallery></pre>
 
  
* <code>caption={caption}</code>: sets a caption on the gallery.
 
* <code>widths={width}px</code>: sets the widths of the images, default 120px. ''Note the plural, width'''s'''''
 
* <code>heights={heights}px</code>: sets the (max) heights of the images.
 
* <code>perrow={integer}</code>: sets the number of images per row.
 
* <code>showfilename={anything}</code>: Show the filenames of the images in the individual captions for each image (1.17+)
 
  
Example:
+
On the main page, add a link for the new section name, below the one currently existing. For example say we want to rename Section 1: Introduction to Section 1: Intro.
  
Coding:
+
Currently it shows
<pre>
 
<gallery widths=60px heights=60px perrow=7 caption="sunflowers are groovy">
 
File:Example.jpg
 
File:Example.jpg
 
File:Example.jpg
 
File:Example.jpg
 
File:Example.jpg
 
File:Example.jpg
 
File:Example.jpg
 
File:Example.jpg
 
File:Example.jpg
 
File:Example.jpg
 
</gallery>
 
</pre>
 
  
Result:
+
<nowiki>[[:Section:1 INTRODUCTION]]</nowiki>
<gallery widths=60px heights=60px perrow=7 caption="sunflowers are groovy">
 
File:Example.jpg
 
File:Example.jpg
 
File:Example.jpg
 
File:Example.jpg
 
File:Example.jpg
 
File:Example.jpg
 
File:Example.jpg
 
File:Example.jpg
 
File:Example.jpg
 
File:Example.jpg
 
</gallery>
 
  
== Linking to an image without displaying it ==
+
Add this below like this:
=== Link to description page ===
 
If you put a colon (<code>:</code>) before <code>{{ns:image}}:</code>, the image will not be embedded and the link will lead to the description page of the file.
 
  
  <nowiki>[[</nowiki>:{{ns:image}}:{{mediawiki:image_sample}}]]
+
  <nowiki>[[:Section:1 INTRODUCTION]]</nowiki>
  <nowiki>[[</nowiki>:{{ns:image}}:{{mediawiki:image_sample}}|Sunflowers]]
+
  <nowiki>[[:Section:1 INTRO]]</nowiki>
  
results in
+
Now click on the original link, then click edit, and select all of the text in the edit window.
  
[[:{{ns:image}}:{{mediawiki:image_sample}}]]
+
Go back to the main page and click your new link "Intro", click edit, and paste all of the text from the old category, into the new one.
[[:{{ns:image}}:{{mediawiki:image_sample}}|Sunflowers]]
 
  
=== Link to another page ===
+
Now the two categories mirror each other (excluding sub content).
{{note|link '''does not work with''' thumb '''or''' frame.}}
 
This will make a 50px width picture with a link to the page [[MediaWiki]]:
 
  
<nowiki>[[</nowiki>File:Wiki.png|50px|link=MediaWiki]]
+
Once that is complete, go back to the "Introduction" page and open each sub category, click edit, and at the bottom you will see
  
[[File:Wiki.png|50px|link=MediaWiki]]
+
  <nowiki>[[Section:1 INTRODUCTION]]</nowiki>
 
+
   
=== Link directly to the media file ===
+
change it to
You can use the pseudo-namespace “{{ns:media}}” to link directly to a file without rendering it, bypassing the description page.
 
 
 
<nowiki>[[</nowiki>{{ns:media}}:{{mediawiki:image_sample}}]]
 
<nowiki>[[</nowiki>{{ns:media}}:{{mediawiki:image_sample}}|Sunflowers]]
 
 
 
results in
 
 
 
[[{{ns:media}}:{{mediawiki:image_sample}}]]
 
[[{{ns:media}}:{{mediawiki:image_sample}}|Sunflowers]]
 
 
 
The same result can be achieved by adding a colon before the namespace (works with categories too):
 
 
 
  <nowiki>[[:</nowiki>{{ns:image}}:{{mediawiki:image_sample}}]]
 
 
 
You can also use:&nbsp;
 
 
 
<nowiki>[[</nowiki>{{#special:Filepath}}/{{mediawiki:image_sample}}]]
 
 
 
which can be used to link to a potential file, even if it doesn't exist. You can also use:
 
 
 
  <nowiki>{{</nowiki>FILEPATH:{{mediawiki:image_sample}}<nowiki>}}</nowiki>
 
 
 
which generates an external URL to the file inline: {{FILEPATH:{{mediawiki:image_sample}}}}
 
 
 
== Requisites ==
 
Before using images in your page, the system administrator of your wiki must have {{mediawiki|Manual:Configuring file uploads|enabled file uploads}} and a user has to [[Help:Managing files|upload the file]]. System administrators may also set the wiki to accept files from {{mediawiki|Manual:Image Administration#Foreign Repositories|foreign repositories}}, such as the [http://commons.wikimedia.org/wiki/Main_Page Wikimedia Commons]. For server side image resizing it is necessary to have a scaler configured (such as GD2, ImageMagick, etc.).
 
 
 
== Files at other websites ==
 
You can link to an external file available online using the same syntax used for linking to an external web page.  With these syntaxes, the image will not be rendered, but only the text of the link to this image will be displayed.
 
<pre>[http://url.for/some/image.png]</pre>
 
  
Or with a different displayed text:
+
<nowiki>[[Section:1 INTRO]]</nowiki>
<pre>[http://url.for/some/image.png link text here]</pre>
 
  
Additional MediaWiki markup or HTML/CSS formatting (for inline elements) is permitted in this displayed text (with the exception of embedded links that would break the surrounding link):
+
Save it.
<pre>[http://www.example.com/some/image.png Example '''<del>rich</del>''' ''<ins>link text</ins>'' here.]</pre>
 
which renders as: [http://www.example.com/some/image.png Example '''<del>rich</del>''' ''<ins>link text<ins>'' here.]
 
  
If it is enabled on your wiki (see {{mediawiki|Manual:$wgAllowExternalImages}}), you can also embed external images. To do that, simply insert the image's url:
+
Once each sub section is moved, simply erase the old section by opening it, and instead of selecting edit, choose delete (may be under the arrow).
<pre>http://url.for/some/image.png</pre>
 
Currently, embedded images cannot be resized, but they may be formatted by surrounding MediaWiki markup or HTML/CSS code.
 
  
If this wiki option is not enabled, the image will not be embedded but rendered as a textual link to the external site, just like above.
+
Verify the page is erased by refreshing the main page. If the link is red, it has been successfully erased. Edit the main page and remove the old link and you have now renamed a section.

4 Paragraphs

MediaWiki ignores single line breaks. To start a new paragraph, leave an empty line. You can force a line break within a paragraph with the HTML tag <br/>.

5 HTML tags

Some HTML tags are allowed in MediaWiki, for example <code>, <div>, <span> and <font>. These apply anywhere you insert them.

6 Internal links

To add an internal link, enclose the name of the page you want to link to in double square brackets. When you save the page, you'll see the new link pointing to your page. If the page exists already it is displayed in blue, if it does not, in red. Selflinks to the current page are not transformed in URLs but displayed in bold. (If you really want to link to the current page, use an anchor (see below), or [[#top|current page]] which always links to the top.)

The first letter of the target page is automatically capitalized, unless otherwise set by the admins, and spaces are represented as underscores (typing an underscore in the link will have a similar effect as typing a space, but is not recommended, since the underscore will also be shown in the text).

7 External links

To add an external link, enclose the name of the page you want to link to in single square brackets. When you save the page, you'll see the new link pointing to your page, with an arrow icon after it to show that it was coded with single bracket external link syntax, and thus may lead to another site.

7.1 How to avoid auto-links

When you put a URL on a wiki page it will be automatically converted into an external link, like this:

http://mediawiki.org

To avoid that effect, put the URL between <nowiki> tags, like this:

<nowiki>http://mediawiki.org</nowiki>

To get this:

http://mediawiki.org

8 Images

Images that are stored on a MediaWiki server are usually rendered by using the File: namespace prefix (but the legacy Image: namespace prefix is still supported as a synonym) as the target of a MediaWiki link. The alternate Media: namespace prefix is also usable to reference the original media file content (for rendering or downloading it separately, out of any MediaWiki page).

9 Supported media types for images

The following file formats are supported by default:

  • .jpg or .jpeg : bitmap image compressed in the standard JPEG format (this lossy format is most suitable for photographs).
  • .png : bitmap image in the Portable Network Graphics format (specified by the W3 Consortium).
  • .gif : bitmap image in the legacy Graphics Interchange Format.

Other formats used on Wikimedia, and commonly enabled elsewhere (these may require extra set-up beyond what is enabled by default):

  • .svg : scalable image in the Scalable Vector Graphics format (specified by the W3 Consortium).
  • .tiff : Tagged image format. Often used for high-resolution archival photographs. <-- Often used with Template:Mediawiki. -->
  • .ogg, .oga, .ogv : Ogg multimedia (audio or video) Not an image format, but treated similarly. <-- Often used with Template:Mediawiki -->
  • .pdf : multipaged documents in the Portable Document Format (initially specified by Adobe). <-- Often used in conjunction with Template:Mediawiki -->
  • .djvu : multipaged bitmap documents in the DejaVu format (most often, scans of books). <-- See Template:Mediawiki -->
    Only a single page of a .pdf or .djvu file is shown at one time.

Other media types may be supported, but it may not be possible to display them inline.

10 Rendering a single image

10.1 Syntax

The full syntax for displaying an image is:

[[File:filename.extension|options|caption]]

where options can be zero or more of the following, separated by pipes (|):

  • Format option: one of border and/or frameless, frame, thumb (or thumbnail);
    Controls how the rendered image is formatted and embedded in the rest of the page.
  • Resizing option: one of
    • {width}px — Resizes the image to fit within the given maximum width in pixels, without restricting its height;
    • x{height}px — Resizes the image to fit within the given maximum height in pixels, without restricting its width;
    • {width}x{height}px — Resizes the image to fit within the given width and height in pixels;
    • upright — Resizes an image to fit within reasonable dimensions, according to user preferences (suitable for images whose height is larger than width).
    Note that the image will always retain its aspect ratio, and can only be reduced (not increased) in size unless it's in a scalable media type (bitmap images cannot be scaled up).
    The default maximum size depends on the format and the internal image dimensions (according to its media type).
  • Horizontal alignment option: one of left, right, center, none;
    Controls the horizontal alignment (and inline/block or floating styles) of the image within a text (no default value).
  • Vertical alignment option: one of baseline, sub, super, top, text-top, middle, bottom, text-bottom;
    Controls the vertical alignment of a non-floating inline image with the text before or after the image, and in the same block (the default vertical alignment is middle).
  • Link option: one of
    • link={target} — Allows to change the target (to an arbitrary page title, or URL) of the generated link, activable on the rendered image surface; e.g. [[File:Example.jpg|20px|link=http://www.wikipedia.org]] renders as Example.jpg (external link), or [[File:Example.jpg|20px|link=MediaWiki]] renders as Example.jpg (internal link).
    • link= (with an empty value) — Displays an image without any activable link; e.g. [[File:Example.jpg|20px|link=]] renders as Example.jpg.
! Link does not work with thumb, thumbnail or frame.
  • Other specific options:
    • alt={alternative text} — Defines the alternative text (maps to the HTML attribute alt="..." of the generated <image /> element) of an image that will be rendered if either the referenced image cannot be downloaded and embedded, or if the support media must use the alternative description text (e.g. when using a Braille reader or with accessibility options set by the user in its browser).
    • page={number} — Renders the specified page number (currently only applicable when showing a .djvu or .pdf file).

The options can be given in any order. If the given options conflict each other, the latter is applied, except for the format options, where the options take the priority in the order of: frame; thumb (or thumbnail); frameless and/or border.

If a parameter does not match any of the other possibilities, it is assumed to be the caption text. Caption text shows below the image in thumb and frame formats, or as mouseover text in border, frameless formats or when the format is omitted. Caption text displayed in the thumb and frame formats may contain wiki links and other formatting. In the other options, wiki-formatting will not work though transclusion will.

If no caption text is supplied, a caption is automatically created showing the file name. To completely remove the caption, set it to <span title=""></span>. For example, [[File:Example.jpg|20px|<span title=""></span>]] renders as .

11 SECTIONS

(May be referred to as Categories in this section)

Categories, a software feature of MediaWiki, provide automatic indexes that are useful as tables of contents.

You can categorize pages and files by adding one or more Category tags to the content text. These tags create links at the bottom of the page that take you to the list of all pages in that category, which makes it easy to browse related articles.

12 Summary

Each of the pages in the Category namespace represents a so-called category, a grouping of related pages, and contains an index for the pages of its category. For example, this page belongs to "Category:Help". If you open the "Category:Help" page, you will see a link to this page there.

When a page belongs to one or more categories, these categories appear at the bottom of the page (or in the upper-right corner, depending on the skin being used).

The category pages themselves contain 2 parts :

  • at their beginning, an optional part may contain text that can be edited, like any other page,
  • at their end, an ever present, automatically generated, alphabetical list of all pages in that category, in the form of links. (In fact, in ASCII order. See Help:Special page).

To assign a category to a page, simply add the link "[[Category:Category name]]" to the page's wikitext. The usual place to add it is at the bottom of the page.

To link a category page within a page as a normal wiki link (without adding the page to the category), prefix the link name with a colon. For example: [[:Category:Not in this category]]

New categories can be created before assigning any page to it, in the same way as any other regular page.

Individual wikis may have their own top-level categories, such as Category:Contents in Wikipedia.

For a complete list of all categories which have at least one page, see Special:Categories.

For a complete list of all created/edited categories, including the ones that don't have any page, see Special:Allpages/Category: (note the colon at the end).

13 Adding a page to a category

To add a page or uploaded file to a category, simply edit the page and add the following text (where Name is the name of the category you want to add it to).

[[Category:Name]]

Any number of Category tags may be added to the page and the page will be listed in all of them. Category tags, along with interwiki language links placed in the sidebar, are usually added at the very bottom of the page for the convenience of other editors.

On a categorised page, categories are displayed in the Categories: box strictly in the order they appear in the wikitext.

13.1 Sort key

By default, a page is sorted within a category under the first letter of its full name including the namespace. Also, MediaWiki groups accented characters separately from their unaccented version, so pages starting by À, Á, Ä, will be listed under separate headings, instead of under heading A.

A sort key specifies under which letter heading, and where in the category list, the page will appear. You can add a sort key by placing it inside the tag after a pipe character. For example, the tag below will add the page under heading "S".

[[Category:Name|Sort]]

Sort keys are case-sensitive, and spaces and other characters are also valid. The order of the sections within a category follows the Unicode sort order. The sort key does not change the page title displayed in the category.

14 Creating a category page

Categories exist even if their page has not been created, but these categories are isolated from others and serve little purpose for organization or navigation.

A category is created by creating a page in the Category: namespace. A category page can be created the same way as other wiki pages (see Help:Starting a new page); just add "Category:" before the page title.

To avoid extra work, try searching within your wiki before creating a new category. The list of all categories can be found in "Special pages" in the "tools" box of the sidebar.

Unlike other wiki pages, it is not possible to rename (move) a category. It is necessary to create a new category and change the Category tag on every page. The new category will not have the older category's page history, which is undesirable if there are many revisions.

15 Managing the category hierarchy

Categories may belong to other categories in a hierarchy. Since category pages are much like any other page, a Category tag may be added to the bottom of a category page.

It is a good idea to organize all categories into a hierarchy with a single top level category. The category structure can take the form of a tree with separate branches, but more often will have a graph structure. Generally, there should be a contiguous chain of parent-child links between each category and the top level category.

16 Linking to a category

To create a link to a category, use a leading colon before the category name (without this colon, the current page would be added to the category):

[[:Category:Help]]Category:Help

To change the link text, write the text inside the link tag after a pipe:

[[:Category:Help|Help category]]Help category

Redirect pages that redirect to categories must also use the colon, otherwise they will be added to the category instead of redirecting.

17 Renaming a Section

On the main page, add a link for the new section name, below the one currently existing. For example say we want to rename Section 1: Introduction to Section 1: Intro.

Currently it shows

[[:Section:1 INTRODUCTION]]

Add this below like this:

[[:Section:1 INTRODUCTION]]
[[:Section:1 INTRO]]

Now click on the original link, then click edit, and select all of the text in the edit window.

Go back to the main page and click your new link "Intro", click edit, and paste all of the text from the old category, into the new one.

Now the two categories mirror each other (excluding sub content).

Once that is complete, go back to the "Introduction" page and open each sub category, click edit, and at the bottom you will see

[[Section:1 INTRODUCTION]]

change it to

[[Section:1 INTRO]]

Save it.

Once each sub section is moved, simply erase the old section by opening it, and instead of selecting edit, choose delete (may be under the arrow).

Verify the page is erased by refreshing the main page. If the link is red, it has been successfully erased. Edit the main page and remove the old link and you have now renamed a section.
