I currently use the following code to populate query string pairs into
variable names.
use CGI;
my $query = new CGI;
foreach $KEY ($query->param()) {
$VARNAME = \(uc($KEY));
$$VARNAME = $query->param($KEY);
$$VARNAME = join(",",@$VARNAME); #Enables us to work with multiple
values items such as <select>
print "$VARNAME is $$VARNAME<BR>\n";
}
however, I understand it is better/safer to write code with "use strict;"
I guess that I would have to add:
my ($KEY, $VARNAME);
to the above, but I'm not quite sure how to tidy up the rest. Could
somebody possibly show me how to tidy the code up and maybe point me in the
direction of some instructions/methods of how to program when using strict.
I would appreciate some examples of common pitfalls when working with
"strict" and workarounds. I have looked at the documentation on "strict"
that comes with Active Perl, however, I didn't find it all that useful, or
the examples all that clear.
Any help would be gratefully appreciated.
TIA
Roland
