Hi again Måns,
Now this time we are going to solve thad riddle!
Try this and I try to explain gor your brain ;–)
---
\define he-she-it(gendervalue:"_false_")
<$vars value="""$gendervalue$""">
<$set name="result" filter="[<value>!prefix[_false_]]" value=<<out>>
emptyValue="it">
result: <<result>>
</$set>
</$vars>
\end
<$checkbox field="gender" checked="he" unchecked="she"> male</$checkbox>
output: <$macrocall $name="he-she-it" gendervalue={{!!gender}}/>
---
It all starts with the macrocall instead of the shorter <<macroname param>>
syntax. Frankly, I don’t know why.
If the input for the macro is empty, we assign the value "_false_" (maybe this
works only with the macrocall syntax).
We assign the input value to a variable so we can use it in the filter later.
The result is the output of a filter: if the input value does not (!) equal
"false" we assign the input value. Else the filter returns empty and we assign
"it". (You can of course change that to "gender unknown" if you like.)
Finally we generate the output starting with "result: …"
Hope that helps. More to come …
Cheers,
Thomas
