<presort> |
|
The Presort extension adds a <presort> tag to the wiki markup. This tag can be used around sortable and non-sortable wikitables to presort the table without the need of an ordered wikitext.
Parameter
[edit]mode
[edit]- column
The table is presorted according to the values in a column.
- key
The table is presorted according to a key.
Default value is "column".
sortcolumn
[edit]defines the sortcolumn. Can only be used with "column" mode. Numbering starts with 1.
Default value is "1".
order
[edit]- asc
ascending order
- desc
descending order
Default value is "asc".
numberingcolumn
[edit]Allows to define a columnnumber, in which automated numbering is filled in. All existing content in this column is overwritten! Default value is -1, which means no numbering.
template
[edit]Allows to define the template used for the key definition. For example templates like dts, sort or hiddensort. Can only be used with "key" mode.
Default value is "dts".
Installation
[edit]- Download and place the file(s) in a directory called
Presortin yourextensions/folder. - Add the following code at the bottom of your LocalSettings.php file:
require_once "$IP/extensions/Presort/Presort.php";
Done â Navigate to Special:Version on your wiki to verify that the extension is successfully installed.
Code
[edit]- Presort.php
