This print line approach to HTML is ugly and others will probably come up with better templating solutions. (Please consider at least multiline here-docs)

Anyway, if you wanna stick with variable interpolation, using a dedicated hash might be better (shorter, self documenting, less error prone,...)

 
my %CHECKED = ( "" => "", 1 => 'checked="checked"');
print "<yadda $CHECKED{ !! $fieldValues{fieldName} } yadda>"

If you don't like the !! double negation make either sure that the values are only true or false (resp. binary) or use a tied hash to do the boolean mapping inside the FETCH.

Making %CHECKED constant or immutable might be a good idea too.
