PHP login functionality

[johnmr]

I am altering an exisitng system for a site which required a person to fill out a form in order to download sample software from the site. This was initially done in PHP. One of the features of the site was that we captured a person's email address, which was stored in a mySQL database and used as a login, so the user wouldn't need to fill out the whole form the next time they came back to the site, just used their email address as a login and then download what they needed.

We are changing this system now, so that the initial form now points to a third party site, which collects the form info (for the sales team), then redirects to the actual software download that the user requested.

I've got all this working well, I think, but can't figure out how to fix it so we can capture the user's email into the database so they won't have to fill out the whole form again when they come back to the site. Anyone know of any tricks to get this to work? Maybe some sort of PHP code to go in the form's submit button that would get this to happen? Any help greatly appreciated.

Thanks in advance

JMR

No you can't do this with PHP. PHP is serverside so you can;t attach it to a button. As the form goes to a third party it cannot also go to you. The best way to do this is (a ssuming the download page in on your site) get the redirect from the login site to pass the email address to you in the url of the redirect.
