I am using the CGI module and can get access to the POST & GET
variables

use CGI;
#create new cgi
my $m_cgi = new CGI;

#put cgi data into hash
my %m_cgi_data = $m_cgi->Vars;

What I would like todo is find some way of knowing whether a variable
is from a GET or a POST as for one form I would like to ignore GET's

Is this possible using cgi.pm?

Thanks

Have you read:
http://perldoc.perl.org/CGI.html#MIX...URL-PARAMETERS
?

yup read it before I posted

either I am not understanding it properly or it doesn't work for me

using url_param & param both returned a GET parameter

Well, that sucks. It does work for me, so I probably understand it
properly. If you showed us some code, maybe I could understand your
misunderstanding and correct it.

So then you know it is from the query string in the URL. Isn't that what
you wanted to know? Doesn't that solve your problem?

OK done some further tests

param returns both GET & POST

url_param returns GET

what I want is just POST but now I understand I can exclude anything in
url_param

Thanks for replying

How about using request_method() to find out how your script was called?

Ah, now I see the problem.
No, param returns either GET or POST--but not both--for any one form
submission.

> url_param returns GET

If the form was submitted with GET, both param and url_param return the
parameters from the URL.

If the form was submitted with POST but also had URL parameters thrown in
too, then param returns only the POSTed parameteters and url_param returns
only the URL ones.

If the form was submitted with POST, then the exclusion has already
been done for you in param(), and you don't need to use url_param. If the
form was submitted with GET, then you could just throw up a "drop dead,
hacker" page and never even look at param.

cgi.pm supports having both get (in the url) and post params on the same
cgi call. it will mix the params from both sources. i am not sure which
will override the other (if that happens). from cgi.pm:

$query = new CGI;

This will parse the input (from both POST and GET methods)
and store it into a perl5 object called $query.

note the 'both' in there.

i never said anything about access params from both get/post. i just was
pointing out that you can use both and cgi.pm will handle it. dealing
with both in a submission is up to you but you can get both sets of
params if desired.

I have added the following code to remove any GET - seems to do what I
want

#create new cgi
$m_cgi = new CGI;

#put cgi data into hash
%m_cgi_data = $m_cgi->Vars;

#remove GET from hash
for my $key (keys %m_cgi_data ) {
delete $m_cgi_data{$key} if $m_cgi->url_param($key);
}
