Question

I want to retrieve the parent of a topic. This works in principle with:

-

The raw code:

%SEARCH{ "^%BASETOPIC%$" scope="topic" web="%BASEWEB%" regex="on" nosearch="on" nototal="on" zeroresults="off" format="- $parent(15, ...) %BR%" }%

But when no parent is set, I don't want to display anything.

How can I turn off the results when nothing is found?

Answer

You can do that with a SpreadSheetPlugin CALC that gets evaluated after the search:

%SEARCH{ "^%BASETOPIC%$" scope="topic" web="%BASEWEB%" regex="on" nosearch="on" nototal="on" zeroresults="off" format="$percntCALC{$IF($EXACT($parent,), , - $parent(15, ...) %BR%)}$percnt" }%

Thanks. But this gets way too complicated for such a simple question. I suggest a new parameter to SEARCH in case of no results: alt="nothing found".
