You saved the values here in macros:
\def\zakon[#1][#2]%
{\doifdefinedelse{zakonkratko:#2}
{\zakonkratko[#1][#2]}
{\bgroup
\nocite[#2]%
\getcitedata[title][#2] to \localtitle
\getcitedata[kratko][#2] to \localkratko
\getcitedata[journal][#2] to \localjournal
\getcitedata[issue][#2] to \localissue
\getcitedata[volume][#2] to \localvolume
\getcitedata[spremembe][#2] to \localspremembe
\footnote{\localtitle\ (\localkratko), \localjournal, št.
\localissue/\localvolume\skip, \localspremembe.}%
\egroup}%
\setvalue{zakonkratko:#2}{done}}
You can check for content in these macros with:
\doifsomething{\localtitle}{\localtitle}
\doifsomethingelse{\localtitle}{\localtitle}{<something else>}
\doifnothing{\localtitle}{<no title>}
\doifelsenothing{\localtitle}{<no title>}{\localtitle}
