[Tutor] CGI problem.

Fri Nov 5 23:00:04 CET 2004

Hi, 

I made a CGI script, that checks if the user entered a vaild pass
(that should be in "pass.txt").
Here is what I did:

import cgi
import cgitb; cgitb.enable()
form = cgi.FieldStorage()
x=open("pass.txt","r")
form.getfirst("pass")
print "Content-type: text/html\n\n"
def printhtml():
    print """
       <html><body>
       <form><input name="pass" type="text"></form>
       """
def checkpass():
    a=x.readline()
    if a==form.getfirst("pass"):
        print "OK, come in."
    else:
        print "Wrong password, try again! "

printhtml()
checkpass()
x.close()

The problem is that when the page opens it writes "Wrong password, try
again! ", and the user dont get a chance to write the password first.
what can I do so that it will work like it shold (first get the
password, and only then say if its good or not).

I know (or at least hope) that there is a very simple solution for
this problem, but cant find it by myself...

Thanks!!
