CGI oddity

ruby-talk

Hi,

I’m trying to use cgi.rb from stdlib, and I have following problem. When I use GET to send data to script,
everything is fine, it’s also fine when I use POST to do this, but I can’t use both in one script.
I.e., if I have URL: http://localhost/cgi-bin/index.rb?page=guestbook, and, I have a form that sends POST data
to it, then variable “page” doesn’t appear in CGI#params hash.
It looks it wouldn’t be hard to hack that in, but maybe there’s another way?

well, if you have a FORM just add an INPUT tag with the type hidden,
something like

<input type=hidden name=page value=guestbook>

and don't use '?page=guestbook'

I’ve had the exact same problem. This is a little part of my solution:

class CGI
def query_parameters
@qp = parse_query_parameters(query_string) if @qp.nil?
@qp
end

 def parse_query_parameters(query_string)
   parsed_params = {}

   query_string.split(/[&;]/).each { |p|
     k, v = p.split('=')
     parsed_params[CGI.unescape(k)] = v.nil? ? nil : CGI.unescape(v)
   }

   return parsed_params
 end

end

Now you should be able to access all the query_parameters from the hash
returned on that method. Regardless of whether the request was POST or
GET. I doesn’t take much effort to include this seemingly with the
original params method, so you don’t have to distinguish between GET
and POST variables.

The full CGI extension I did, which also turns
"person[address][street]" style inputs into hashes (like PHP), is
included in Rails. The upcoming web-application framework that
currently is just the mirage available at http://rails.nextangle.com/
but hopefully soon will be a released reality.

This was just an example, there could be a lot of other query arguments and I’m not sure
if I want to maintain their lists in each form that’s used through index.rb

Thanks, I’ll checkout the code and see how can I use it :slight_smile:

He-he, my problem was related to my yet-to-be-released MuraveyWeb project,
it’s a web-framework also :slight_smile:
