Hello all...
In my example-driven world I find [something like] this in
'CGI Programming with Perl', constructed in main::
if ($CGI->param("Screen3")) {
showmeScreen3($CGI);
}
elsif ($CGI->param("Screen2")) {
showmeScreen2($CGI);
}
else {
showmeScreen1($CGI);
}
This is a pretty old book and I'm wondering if there's a
newer, better way? I wish to be able to achieve what would
be the results of this (if it were possible):
if ($CGI->param("Screen3")) {
showmeScreen3($CGI, %widgets);
}
...
but, of course, %widgets doesn't exist at compile time.
Something I read in perlreftut made me think I might be
able to use a reference here. Possible?
Alternatively, is there syntax that allows passing a hash
using a hidden input variable? i.e.:
<input type=hidden name=widgets value="%widgets">
Thanks,
Jon
