== Syntax ==

=== Displaying plain text as-is (without parsing) ===

Text that is placed between the 'pre' tags will not be parsed and will display line breaks as is!

Example:

<pre>
Hello
world
</pre>

Would normally be displayed as:
<pre>
Hello world
</pre>

But if you use:

<pre>
<pre>
Hello
world
</pre>
</pre>

It will display like this:
<pre>
Hello
world
</pre>

To display text that would normally be parsed, break it up by putting a <b>zero width space</b> <code>&#8203;</code> in the middle of it.

For instance, <code><&#8203;font></code> will display as <code><font></code> and <code>&#82&#8203;03;</code> will display as <code>&#8203;</code>

=== Including raw html ===

Edit the file "LocalSettings.php" in your Mediawiki folder.

Add the line <code>$wgRawHtml = true;</code>

You can now include raw html between < html> tags:
<pre>
== This is a wiki page ==
<html>
<iframe width="420" height="315" src="https://www.youtube.com/embed/somevideo" allowfullscreen></iframe>
</html>
</pre>
<br/><br/>

=== Removing automatic numbering in table of contents ===

Go to "<nowiki>http://mydomain.com/wiki/index.php/MediaWiki:Common.css</nowiki>"

Edit the page and add the line:
<syntaxhighlight lang="css">
.noautonum .tocnumber { display: none; }
</syntaxhighlight>

Now, in any page that you don't want numbering, add the line:
<syntaxhighlight lang="html">
<div class="noautonum">__TOC__</div>
</syntaxhighlight>
<br/><br/>

=== Removing the table of contents ===

Add the keyword <code>__NOTOC_</code> somewhere in your page.
<br/><br/>

=== Continue Numbering After a Tag ===

If written like the following, the numbering will break and start over at 1 on "Item 3":
<pre>
# Item 1
# Item 2
<syntaxhighlight lang="shell">
echo "hello world"
</syntaxhighlight>
# Item 3
# Item 4
</pre>

<b>Example result:</b>

<div style="border:1px solid #999;padding:20px;">
# Item 1
# Item 2
<syntaxhighlight lang="shell">
echo "hello world"
</syntaxhighlight>
# Item 3
# Item 4
</div>

But if written like the following, the numbering will continue (notice the colon ':' on the third line):

<pre>
# Item 1
# Item 2
#:<syntaxhighlight lang="shell">
echo "hello world"
</syntaxhighlight>
# Item 3
# Item 4
</pre>

<b>Example result:</b>

<div style="border:1px solid #999;padding:20px;">
# Item 1
# Item 2
#:<syntaxhighlight lang="shell">
echo "hello world"
</syntaxhighlight>
# Item 3
# Item 4
</div>

=== Prevent Wiki Formatting ===

The <i>nowiki</i> tag let's you prevent automatic formatting.

For example, bold text and links written like this:
<pre>
'''Bold text''' http://example.com
</pre>

Will display like this:
<div style="border:1px solid #999;padding:20px;">
'''Bold text''' http://example.com
</div>

But if you use the <i>nowiki</i> tag:
<pre>
<nowiki><nowiki>'''Bold text''' http://example.com</nowiki></nowiki>
</pre>

It will display like this:
<div style="border:1px solid #999;padding:20px;">
<nowiki>'''Bold text''' http://example.com</nowiki>
</div>
<br/><br/>

== Local Settings ==

=== Hide IP Address in Header ===

I use a web proxy for my wiki, and having the IP address in the header reveals the LAN IP address of my proxy server. To hide this, I added the following parameter to the <code>LocalSettings.php</code> file:
<syntaxhighlight lang="php">
# Do not show client IP address in header
$wgShowIPinHeader = false;
</syntaxhighlight>

== Configuration Pages ==

=== Global CSS Stylesheet ===

<nowiki>http://mydomain.com/wiki/index.php/MediaWiki:Common.css</nowiki>

=== Sidebar Navigation List ===

<nowiki>http://mydomain.com/wiki/index.php/MediaWiki:Sidebar</nowiki>

=== Main Page Definition ===

<nowiki>http://mydomain.com/wiki/index.php/MediaWiki:Mainpage</nowiki>

=== Version ===

<nowiki>http://mydomain.com/wiki/index.php?title=Special:Version</nowiki>

=== Batch Upload ===

Using the [https://www.mediawiki.org/wiki/Extension:SimpleBatchUpload SimpleBatchUpload] extension:
<nowiki>http://mydomain.com/wiki/index.php?title=Special:BatchUpload</nowiki>

== Errors ==

=== Fatal exception of type MWException Error ===

This error occurred for me when I tried to upload a file. The "images" folder within the Mediawiki folder must be owned by the group "www-data" or "apache" (the web user of your particular install) and the permissions must be set to 775.

Assuming your web user is "www-data" and your Mediawiki folder is "/var/www/html/wiki":

<syntaxhighlight lang="shell">
cd /var/www/html/wiki
sudo chown -R :www-data images
sudo chmod -R 775 images
</syntaxhighlight>

== Maintenance ==

=== Delete All Old Revisions ===

Run the file (where ROOT is the wiki root):
<source>
php ROOT/maintenance/deleteOldRevision.php --delete
</source>

You should also delete old archived revisions:
<source>
php ROOT/maintenance/deleteArchivedRevisions.php --delete
</source>
