OK, it seems
Code:
Source template:{tags}
Destination field:authors
does the trick.
How can I truncate the author_sort here
Code:
Source template:{author_sort}: {title}
Destination field:title
to the first author's surname, please?
I found this somewhere
Code:
{author_sort:re(([^\,]+)(\,|$)(.*),\1)}
would it do the trick, and do I really need all of these brackets. I can't find explanations for them in the
online help.
