This extensions adds the ability to create a N-column table of categories to a wiki site and it creates a link to each category. I couldn't find something simple that would do this, so I decided to write one myself. Any improvements to make it more dynamic would be appreciated.
To change how many Columns you want on a page, change the column variable value. Other than that, it is all set to go!
This extension can be called with:
<categorylinks />
or just
<categorylinks>
Installation
Copy code below to ../extensions/CategoryLink.php and include in LocalSettings.php.
Code
<?php
$wgExtensionFunctions[] = 'registercategorylinks';
$wgExtensionCredits['parserhook'][] = array(
'name' => 'Category Links',
'author' => 'Kyle van der Meer',
'url' => 'http://www.mediawiki.org/wiki/Extension:CategoryLink',
'description' => 'Displays a N-column table of categories.',);
function registercategorylinks() {
global $wgParser;
$wgParser->setHook('categorylinks', 'printcategorylinks');
}
function printcategorylinks() {
global $wgDBuser,$wgDBpassword, $wgDBname,$wgDBserver,$IP;
$link = mysql_connect($wgDBserver, $wgDBuser, $wgDBpassword)
or die('Could not connect: ' . mysql_error());
mysql_select_db($wgDBname) or die('Could not select database');
$query = 'SELECT cl_to FROM categorylinks group by cl_to';
$result = mysql_query($query) or die('Query failed: ' . mysql_error());
$num_rows = mysql_num_rows($result);
while($num_row = mysql_fetch_array($result))
$data[] = $num_row['cl_to'];
$columns=3;//change this number to the number of columns you want.
$width=ceil(100/$columns);
$args.="<table width=\"95%\" style=\"border-style:outset; border-width:2px; border-color:#006600;\" align=\"center\">\n";
for($j=0;$j<$num_rows;$j++){
if(($j % $columns)==0)
$args.="\t<tr>\n";
$args.="\t\t<td width=\"$width%\" valign=\"top\"><p><a href=\"../index.php/Category:$data[$j]\">".preg_replace("/_/"," ",$data[$j])."</a></p>\n";
if(($j % $columns)==$columns-1)
$args.="\t</tr>\n";
}
$args.="</table>";
return (''.$args.'');
}
An alternative version which makes use of the internal code for Special:Categories (seems to work as of version 1.10.1) This version is not as versatile, and is only capable of generating a single column, not a table.:
<?php
$wgExtensionFunctions[] = 'registercategorylinks';
$wgExtensionCredits['parserhook'][] = array(
'name' => 'Category Links',
'author' => 'Kyle van der Meer, modified by Tomer Gabel',
'url' => 'http://www.mediawiki.org/wiki/Extension:CategoryLink',
'description' => 'Displays the category list inline',);
function registercategorylinks() {
global $wgParser;
$wgParser->setHook('categorylinks', 'printcategorylinks');
}
require_once( "includes/Pager.php" );
require_once( "includes/SpecialCategories.php" );
function printcategorylinks() {
$cap = new CategoryPager();
return ( '<ul>' . $cap->getBody() . '</ul>' );
}
