Using PHP, I need to collect a user's email and password, store them in the DB and then submit those two data to a third party login page and also send the user to the resulting page. So they are thus able to login to the third party site from my site. I tried using curl but it doesn't seem to give me the resultant page on the other site. Is it supposed to? The other way I can do it is to send a page to the browser with a hidden form (filled in with email/password) 'pointing' to the third party site and then automatically submit that using JS. I think this is an old problem but I don't have any better solutions for it today. Any better ideas? Thanks.
