Subject: cgi params in ruby

Hi Rubiers,


I can't figure out a way to make the following code do what I want:

#!/usr/bin/ruby1.8  -w

require 'cgi'

cgi=CGI.new("html3")
cgi.out() do
cgi.html() do
cgi.body() do
     cgi.form("get")  do

     cgi.params.to_a.each {|key, val|
         cgi.text_field(key, val.to_s) +
         cgi.br
     } +
     cgi.submit("Okey Dokey?")

     end
end
end
end

So say I post in something this when I run the script on the command line:


(offline mode: enter name=value pairs on standard input)
lname=davis;fname=cere

../t.cgi:15:in `+': cannot convert String into Array (TypeError)
	from ./t.cgi:15
	from ./t.cgi:9:in `form'
	from ./t.cgi:9
	from ./t.cgi:8:in `body'
	from ./t.cgi:8
	from ./t.cgi:7:in `html'
	from /usr/lib/ruby/1.8/cgi.rb:1678:in `html'
	from /usr/lib/ruby/1.8/cgi.rb:1678:in `html'
	from ./t.cgi:7
	from ./t.cgi:6:in `out'
	from ./t.cgi:6


What I want to happen is for the cgi script to print the lname and fname 
into two text_field boxes but I am having trouble tracing through this 
error.  Can anyone help?

Thanks,
Cere
