Reading documentation.. and it looks like $r->param is what I need :) Thanks!
--- perldoc Apache::Request ---
param
Get or set request parameters (using case-insensitive
keys) by mimicing the OO interface of "CGI::param".
Unlike the CGI.pm version, Apache::Request's param
method is very fast- it's now quicker than even
mod_perl's native Apache->args method. However,
CGI.pm's "-attr => $val" type arguments are not sup-
ported.
# similar to CGI.pm
my $value = $apr->param('foo');
my @values = $apr->param('foo');
my @params = $apr->param;
# the following differ slightly from CGI.pm
# assigns multiple values to 'foo'
$apr->param('foo' => [qw(one two three)]);
# returns ref to underlying apache table object
my $table = $apr->param; # identical to $apr->parms - see below
parms
Get or set the underlying apache parameter table of
the Apache::Request object. When invoked without
arguments, "parms" returns a reference to an
Apache::Table object that is tied to the
Apache::Request object's parameter table. If called
with an Apache::Table reference as as argument, the
Apache::Request object's parameter table is replaced
by the argument's table.
# $apache_table references an Apache::Table object
$apr->parms($apache_table); # sets $apr's parameter table
# returns ref to Apache::Table object provided by $apache_table
my $table = $apr->parms;

ARHG.
I want to stay as far away from use CGI; as possible =/
*sigh*
mod_perl and the methods available in the apache request object shuold beable
to replace CGI.pm entirely, especially when you have a highly customized
RequestHandler :/
Guess I'll see what happens, since I need cookie headers to work AND now
multiple values for one param.

Re: select multiple
CGI.pm does the trick for me, the multi values are seperated by \0
< select name="yadda" multi>
yadda1
yadda2
yadda3
my $CGI = new CGI();
%form_data = $CGI->Vars;
@options = split("\0",$form_data{'yadda'});
$options[0] = yadda1, $options[1] = yadda2 etc .
Not usable live code obviously, but you should see the idea...

Re: select multiple
> Because there is no way to create a delimiter that the potential data

delimiter like a comma, or the like. So (though I can't speak for all
browsers most will do the same) each value is passed with the same key, so
your string ends up like:

keys with some known delimiter (aka cgi-lib.pl used to use the null character
\0). So it depends on your request parser, some provide multiple manners (I
think the standard CGI does). Have a look at the respective docs for how your
parser handles it, unless you are writing a parser...but then why do that with
so many good freely available ones?
Interesting.
So in mod_perl, I would use $r->args{__what__} to get to it? Heh.
I'll email the mod_perl list..

i think those semantics were borrowed from CGI->param. as an alternative,
you can use $apr->parms, which is an Apache::Table object.

Of course, $apr->param("selectmultiplename") returns an array of
the values in an array context.
Subtle. :)

libapreq and select multiple?
Is it just me, or does libapreq not handle the response from correctly? It appears to only make one of the values
accessible.
>From what I can tell, this appears to go all the way down to the
Apache::Table implementation, where the underlying Apache data
structure does not quite have the perl semantics of no duplicate
keys.
My ideal would be for $apr->param("selectmultiplename") to return
an array ref of the values. But I don't really have much of a clue
of where to start to implement this.
Thoughts?
Jim
