Version

This wiki has the Arrays extension installed, which adds a few additional parser functions to the MediaWiki parser to deal with arrays.

For example, {{#arraydefine:things|one&two&red&blue&this&that&up&down|&}} defines an array named things with the values [ "one", "two", "red", "blue", "this", "that", "up", "down" ] because the character & was used as the delimiter separating elements.

Given this definition, some example uses are:

Function	Description	Usage	Value for the things array
{{#arrayprint}}	Print out an array	{{#arrayprint:things}}	one, two, red, blue, this, that, up, down
{{#arrayindex}}	Access a specific index (indices start at 0)	{{#arrayindex:things|3}}	blue
{{#arraysize}}	Retrieve array size	{{#arraysize:things}}	8
{{#arraysearch}}	Search for a value (returns index or empty string)	{{#arraysearch:things|red}}	2
{{#arraysearch}}	Search for a value (substitute values if found or not)	{{#arraysearch:things|red|0|yes|no}}	yes
{{#arraysearch}}	Search for a value (substitute values if found or not)	{{#arraysearch:things|purple|0|yes|no}}	no
