Dynamic FORM names

[Juhani Elbanvetäjä]

Hey,
I've been wondering for a while if it is possible to have dynamic form
names..
To make it clear, I've used common parse_form subroutines and then read form
querys:
$form_input = "$FORM{'form_name'}";
Now, when I have manymany checkboxes in my form I need to write every
form_name manually because the code above doesn't quite accept variables as
follows:
$form_input = "$FORM{$form_name}";
no matter whether I use " '' " or not.
I would appreciate a solution for this problem. At the moment I'd like to
think that it lies in the parse_form subroutine...?

That sounds like horrors from the 90's.

use CGI;

$form_input = "$FORM{$form_name}";

my $cgi = new CGI;
$foo = $cgi->param( $bar );

read form querys:

What is a common parse_form subroutine? The only standard way of parsing
CGI requests is with CGI.pm. There is no way for us to know what you are
using to parse CGI requests if you are not using CGI.pm.

$form_input = "$FORM{'form_name'}";

See:

Now, when I have manymany checkboxes in my form I need to write every
form_name manually because the code above doesn't quite accept
variables as follows:
$form_input = "$FORM{$form_name}";
no matter whether I use " '' " or not.

Please post a short but complete script illustrating the problem you are
having. Please do read the posting guidelines for this group to learn

I do not know as I am not sure what the problem is and what parse_form
does.

Yes, of course.

To make it clear, I've used common parse_form subroutines and then read form
querys:
$form_input = "$FORM{'form_name'}";
Now, when I have manymany checkboxes in my form I need to write every
form_name manually because the code above doesn't quite accept variables as
follows:
$form_input = "$FORM{$form_name}";
no matter whether I use " '' " or not.

Exactly what do you mean by "doesn't quite accept"? Whatever you mean, I
find it hard to believe that you can't access a hash value while
specifying the key as a variable.

our %FORM = ( somename => 'somevalue' );
my $form_name = 'somename';
my $form_input = $FORM{$form_name};
print "$form_input\n";

Outputs:
somevalue

Accordingly, I'd guess that you are making some other mistake.

Doing so you'll see that in order to increase your chances to get help,
you are recommended to post a short but complete program that others can
copy and run and that demonstrates the problem you are having.

If that's actually the case, the only solution to your problem you are
likely to get here is that you'd better start using the more up-to-date
parsing routine provided by CGI.pm.
