( #3333=superdoc: print w/ replies, xml ) Need Help??
I'm trying to make a generalised form-creation script, with a certain look and feel, that I can re-use for various things, using CGI.pm.

Here's an example:

%fields = ( 'name', 'textfield', 'email', 'textfield', 'site name', 'textfield', 'description', 'textfield', 'comments', 'textarea' ); foreach $key (keys(%fields)) { $thisrow = td({-align=>right,-valign=>TOP},$key); if($fields{$key} eq 'textfield'){ $thisrow .= td({-align=>left,-valign=>TOP}, textfield(-name=>$key,-size=>50,-maxlength=>80) ); } if($fields{$key} eq 'textarea'){ $thisrow .= td({-align=>left,-valign=>TOP}, textarea(-name=>$key,-cols=>50,-rows=>10) ); } push(@rows,$thisrow); } print table({-border=>1,-width=>'50%'}, Tr(\@rows) );
But as you can see, it's not going to be very generalised, because I'm having to test for the type of field every time: if it's a textfield, do the textfield thing, if it's a textarea, do something else.

What I can't figure out is how to do this:

$thisrow .= td({-align=>left,-valign=>TOP}, $fields{$key}(-name=>$key)); # make a textfield # because the value is # 'textfield' - DWIM!
i.e. call the particular CGI.pm sub using the value, which is the name of that sub.

Any help greatly appreciated...
