Apache2::Request param repetitions

[Ted <mp...@netcasters.com>]

Hi,

I am using the param method to retrieve form data.  I have a checkbox
field called user_status which has three values:  Active, Inactive and 
Deleted.
If all three boxes are checked and the form is submitted, the user_status
field is returned by the param method three times.  This seems redundant and
am wondering if this was intended or a bug. 

Apache 2.2.3
mod_perl 2.0.2
libapreq 2.0.8

Thanks,
Ted

Code looks like this:
--------------------
my $ar = Apache2::Request->new($r);
foreach $key ($ar->param()) {
    if ($key eq 'user_status') {
        warn "$key\n";
        foreach ($ar->param($key)) {
           warn "-- $_\n";
        }
    }
}

Output looks like this:
----------------------
user_status
-- Active
-- Inactive
-- Deleted
user_status
-- Active
-- Inactive
-- Deleted
user_status
-- Active
-- Inactive
-- Deleted

# returns ref to APR::Request::Param::Table object representing

my $table = $req->param;
@table_keys = keys %$table;

That's true, I could do that, but my aim is to have a general purpose
form reader.  I want to loop through all form elements and load
up a hash for processing later.  I could put all encountered param
names in a hash prior to processing, to eliminate the problem, but
thought the issue was worth mentioning.

i think its because of the way that you're looping it...

the browser sends
	user_status= active
	user_status= inactive
	user_status= deleted
and your loop is picking up all 3

if you call param('user_status') you should just get an array of  
['active','inactive','deleted']
