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.
ifeq

ifexist

ifexpr

rel2abs

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.

coming soon.
