Look at the HTML source of the page and find the hidden field and write a regex to pull it out. I'm willing to help if you post the form's HTML. Something like this: preg_match('!<input[^>]*type=("|'|)hidden\1[^>]*name=("|'|)NAMEOFTHEFIELD\2[^>]*value=("|')([^\3]*)\3[^>]*>!i, $text, $matches); You value should be in $matches[4]. Note: this won't work if the value doesn't have quotes around it. If it doesn't, you can use a differen regex. -- Justin Patrin
