Accessing all CGI input parameters via loop ?

[- Bob -]

Perl newbie question:

I need a little loop that will let me access all of the input
parameters from an HTML form in a generic way without knowledge of the
specific variable (html form field) names.

I know how to do this: my $name = (param("name"));

But, when I don't know the field names, how do I access the structure
of the param's with an index or other non-field-specific technique?

Code snippet appreciated, like I said "newbie"

Thanks,

You don't need a loop for this. But if you really wanted to:
my %value_of;
for my $input (param()) {
$value_of{$input} = param($input);
}

Like I said, you don't need the loop for this, because CGI.pm comes
with a way to generate this hash:

my $value_of_ref = Vars();

Or you could even just import them all into a bunch of package
variables:

import_names('R');
print "$R::name, $R::value, $R::age\n"; #etc

There are a lot of options that you may not be aware of yet.

I still have a more traditional programming mindset

But if you really wanted to:
my %value_of;
for my $input (param()) {
$value_of{$input} = param($input);
}

Thanks, that got me started.

Will do... thanks for the jumpstart.
