A parser function is a special kind of magic word that is most useful for templates.
This WikiIndex:Parser functions article is a WikiIndex 'stub'. If you are familiar with, and understand the WikiIndex policy system, you can help by expanding this WikiIndex stub article, thanks. :-)
List[edit]
expr[edit]
coming soon.
if[edit]
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 if example. If {{if example|WikiIndex}} is entered, 'The name of this site is WikiIndex.' will show up because value was specified, as 'WikiIndex'. {{if example|not WikiIndex}} makes 'The name of this site is not WikiIndex.', because value is specified, as 'not WikiIndex'. {{if example}} makes just 'This site has an unknown name.' because it was left blank.
ifeq[edit]
coming soon.
ifexist[edit]
coming soon.
ifexpr[edit]
coming soon.
rel2abs[edit]
coming soon.
switch[edit]
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 switch example. {{switch example|a}} gives 'argh' because a is entered. {{switch example}} gives 'nothing', because the template was left blank. {{switch example|d}} gives 'nothing', because d doesn't exist in the template.
