How to redirect a form after submit(form sends email)

[metalforever]

How do you redirect a form after submit(form sends email) ? This is pretty urgent for me. I have included the code in a pastebin.

http://pastebin.org/249014

process_form sends the email. The redirect is easily findable.


Thanks.

Normally to do this you would have to send a header, but headers must always be sent before anything else to the browser or you will get an error. To fix this, I create an output buffer at the beginning of my script and flush the data at the end. This buffer only sends the data to the browser once you flush the data. This allows any headers to be sent before anything and avoid any errors. So you want to do this first:

// Create the output buffer at the beginning of the script
// I would put this on line 1 before the session since a session is
// also a header and it will pass through the buffer anyways
ob_start():

// At the end of the script, then flush the data out and end the buffer
ob_end_flush();

Once you create your buffer, then just put in the header whenever you want to do the redirect. It should look like this:

// Send the header using the header function
// Replace example.com with the url you want to redirect to
header("Location: http://www.example.com/");
