WikiIndex:Parser functions
ParserFunction is a special kind of magic word that is most useful for templates.
List
expr
coming soon.
if
Shows different values when entered.
Code:
{{ #if: {{{value|}}} | what to show if activated | what to show if not }}
Example:
{{ #if: {{{1|}}} | The name of this site is {{{1}}}. | This site has an unknown name. }}
Let's say this is included in the template ifExample. If {{ifExample|WikiIndex}} is entered, "Template:IfExample" will show up because value was specified, as "WikiIndex". {{ifExample|not WikiIndex}} makes "Template:IfExample", because value is specified, as "not WikiIndex". {{ifExample}} makes just "Template:IfExample" because it was left blank.

switch
Compares values.
Code:
{{ #switch: value
| value1 = what to show if value1 is entered
| value2 = what to show if value2 is entered
| | what to show if something else is entered
| #default = what to show if nothing is entered
}}
Example:
{{ #switch: {{{1}}}
| a = argh
| b = blah
| c = cough
| | anything
| #default = nothing
}}
This is included in the template switchExample. {{switchExample|a}} gives "Template:SwitchExample" because a is entered. {{switchExample}} gives "Template:SwitchExample", because the template was left blank. {{switchExample|d}} gives "Template:SwitchExample", because d doesn't exist in the template.
