I've been trying the hidden field, but the problem is that when I set the
variable flag, it stays in memory. I would rather just pass a var like I've
been trying, but I don't think it's possible. Any ideas? Is a session cookie
the only way? Here's more simplified code:
#!/usr/bin/python
import cgitb; cgitb.enable()
import cgi
import sys,os
sys.path.append(os.getcwd())
import MySQLdb
import string, re
def client():
form = cgi.FieldStorage()
client = string.replace(string.replace(form.getfirst('client', ''), "'",
'''), '"', '"')
flag = form.getfirst('flag', '')
print "Content-Type: text/html"
print
print """
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Frameset//EN" "
http://www.w3.org/TR/xhtml1/DTD/xhtml1-frameset.dtd";>
<head xmlns="http://www.w3.org/1999/xhtml";>
<body>
"""
if flag == '':
print """
<form method="post" action="client.py">
Company Name: <input type='text' value='' size='20' maxlength='100'
name='client' /><br />
<input type='hidden' name='flag' value='y' />
<div align='center'>
<input type='submit' value=' Send ' />
</div>
</form>
</body></html>
"""
else:
host = 'h'
db = 'db'
user = 'u'
passwd = '1'
database = MySQLdb.connect(host, user, passwd, db)
cursor = database.cursor()
cursor.execute('insert into companies (client);' % (client))
cursor.close()
print '</body></html>'
client()
TIA,
V
