Subject: Re: Adding file directory automatically

Hi,

Yeah I have a File.open function opening, a file called david.txt. In
that file it has a few bit of information. One of those pieces of
information is price. £0.00. The code needs to open the text file
david.txt, add it to an array and then save it, displaying the new
price. I can do this fine, but I basically want to have it that when the
user inputs their bid via a form input and submit, it opens the file
dynamically, father than having 12 different bid.cgi files for each text
file.

Hope this explains it a bit better the code is as follows:
#Displaying information
#!/media/Apache/ruby/bin/ruby
#!/usr/local/bin/ruby
#encoding: utf-8
puts "Content-type: text/html\n\n"

#Adds information from david.txt to an array

f = File.open("../logs/david.txt")
a = f.readlines

puts "<html>"
puts "<head>"
puts "<title>David Quetta - Nothing But the Beat</title>"
puts "</head>"
puts "<body>"
puts "<p>Name :"
puts  a[0]
puts "</p>"
puts "<p>Description :"
puts  a[1]
puts "</p>"
puts "<p>Price :&#163;"
puts a[2]
puts "</p>"
puts "<p>Item Number :"
puts a[3]
puts "</p>"
puts "<form method='post' action='/cgi-bin/bid.cgi'>"
puts "Bid: &#163;<input type='text' name='bid'>"
puts "<input type='submit' value='Submit bid'>"
puts "<input type='reset' value='Reset bid'><br />"
puts "<small>Please enter in the format &#163;0.00</small>"
puts "</form>"
puts "</body>"
puts "</html>"

#Adding bid (its broken at this stage)
#!/media/Apache/ruby/bin/ruby
#!/usr/local/bin/ruby

#Adds information from david.txt to an array

f = File.open("../logs/david.txt")
a = f.readlines

#Sets params for form data
require 'cgi'

cgi = CGI.new()
bid = cgi.params['bid']

a[2] = bid

puts "Content-type: text/html\n\n"

puts "<html>"
puts "<head><meta http-equiv=\"REFRESH\"
content=\"4;url=/cgi-bin/david.cgi\">"
puts "<title>Thank you</title>"
puts "</head>"
puts "<body>"
puts "<p>Thank you for your bid, it will now be logged and you will be
redirected now.</p>"
puts "</body>"
puts "</html>"

In the bid.cgi which is the second file, the f = File.open needs to be
changed automatically.

Thanks
