Is it possible to have a button that submits (to formail) and posts (to Verisign). I want one button to do both actions at the same time for the same form data that someone fills out?
There's no way that I know of. You could have it submit to a script that processed the data, like sending an email, then writes the data to a page and use javascript to submit the second page. The user would have to have javascript enabled for it to work though. If one of the pages accepts the variables from a get request then you could use a server side redirect on the second page to pass the data. This way wouldn't require javascript but the the second destination would have to be able to work with it.
Using PHP, you can have the info emailed to a person and submitted to a database all at the same time. You can also do this with ASP and Cold Fusion, but I'm really into PHP right now.
PHP is the future... Once PHP 5.0 comes out...it'll be completely object oriented. I can't wait for java servlets, jsp, asp, CF and whatever other language to be blown out of the water.
