Template:If

International Game Developers Association

[edit] Usage

{{if
  |test=VARIABLE_OR_PARAMETER_TO_TEST
  |then=code if 'test' is not empty
  |else=code if 'test' is empty
}}

Parameter else is optional. So you may also do:

{{if
  |test=VARIABLE_OR_PARAMETER_TO_TEST
  |then=code if 'test' is not empty
}}

For using it with parameters in a template use this method:

{{if
  |test={{{field_name|}}}
  |then={{{field_name}}}
  |else=Nothing
}}

On one line:

{{if|test={{{field_name|}}}|then={{{field_name}}}|else=Nothing}}
