| 1 | The test value | no | |
| 2 | The value to return | no | |
This template returns parameter 2 only if parameter 1 is not blank. The main use of this is in other templates, in converting parameters.
Example:
- Given {{2if1 | {{{a|}}} | [[{{{a}}}]] }}:
- If parameter a=train, then the template will return [[train]].
- If parameter a is blank, then the template will return nothing.
