forwarding cgi->param()

[xhoster]

hi,
how to forward parameters from $cgi->param() to another page when I
don't know how many parameters are there and how they are called?

Have the read the description of the param() method? If so, why don't
you know how many parameters there are and how they are called?

you normally don't forward or pass params to another page, but you do to
another script.

anyway, from your description of the problem, i'm going to guess that
you need to look into the CGI module's query_string() method.

Not clear if you are generating another form and want to pass variables
through it, or attempting to redirect them to some other handler. But to
pass submitted variables through another form as hidden variables,
somewhere within the CGI generated form do something like:

foreach ($cgi->param) { print $cgi->hidden($_), "\n"; }

Of course you would need to make certain that and subsequent forms use
different field names so they do not get mixed up with previous fields.
And you could eliminate having to replicate '$cgi->' so often in your
script by using function method instead of object method.

Their is VARS..

my $FORM = $cgi->Vars;

now $FORM{'name'}

Whose is what?

now $FORM{'name'}

Is that supposed to be Perl?

Perhaps you mean: my %FORM = $cgi->VARS;

now $FORM{'name'}

But how would that help at all if he does not know which 'name's were
passed from previous form?

Sloppy English...

my $FORM = $cgi->Vars;

now $FORM{'name'}

....sloppy code.

Nothing new there.

Yes a hash. Sorry.

Yes a hash. Sorry.

According to "perldoc CGI" both work. A hashref (to a tied hash) is
returned to the scalar. An untied hash is probably preferable unless
you want to change variables through the hash, which is what the tie does.
