I need help with PHP, cURL, and POST

Richard, Thanks for your answer. What do you mean about the submit input? I thought that was just a text link to cause the form to be submitted when clicked. I didn't know that it sent anything to the server. (As you can tell, I don't know anything about asp except what it stands for.) The paymentidfilter is a legitimate field, and works in the form and in the GET version of the cURL stuff. You're right that I get no curl error, and the curl info didn't seem to have anything interesting in it. It seems that e-gold has as its error response to send the login page for whatever one is asking for. This is not very helpful (at least to me). I'll see if I can get this LiveHTTPheaders thing for firefox, since firefox is my main browser. From what I read, the cookie jar and file options take the name of the same file as their arguments. Is there any path information that is required? Can I just use something like "mycookies.txt" or must it have a specific extension? Thanks again.
