Your use of a hash to define your fields leaves a bit of a dilemma: you never know what order they will be in when you invoke keys. This means you have given perl control over the order the fields appear in the form. You'd be better off using an array.

Instead of storing the field type, store a code reference to a subroutine that can generate that type of tag. The sub can take arguments to control creation of the input field.

use CGI qw(:standard); sub TEXTFIELD { my ($name,$siz,$max)=@_; $siz ||= 50; $max ||= 80; return textfield(-name=>$name,-size=>$siz,-maxlength=>$max); } sub TEXTAREA { ...generate a textarea... }; sub SUBMIT { ...generate a submit button... }; my @fields = ( { type=>\&TEXTFIELD, args=>['name'] }, { type=>\&TEXTFIELD, args=>['email'] }, { type=>\&TEXTFIELD, args=>['site name'] }, { type=>\&TEXTFIELD, args=>['description'] }, { type=>\TEXTAREA, args=>['comments'] }, ); my @rows; for (@fields) { my $control = $_->{type}->(@{$_->{args}}); push @rows,td({-align=>left,-valign=>TOP},$control); }
--- print map { my ($m)=1<<hex($_)&11?' ':''; $m.=substr('AHJPacehklnorstu',hex($_),1) } split //,'2fde0abe76c36c914586c';
