php - URL forward

[rh71]

Have a php script that processes a form... and I need it to forward to a specific URL after X seconds. Can't use META REFRESH because there's a condition on the page so it would only forward if it met one of the conditions.

What's the code to forward after X seconds or even simply go to a page immediately, via php ?

PHP is server-side, so you can't. Javascript would be what you'd use. I dunno how to do a timer with Javascript but when you reach zero (and your other conditions are met), you'd just do window.location = "<url>".

To immediately forward with PHP you could send an HTTP Location header: header("Location: <url>"). But remember that you have to do it before you send ANY content to the browser.

If it's alright for it to forward immediate, I'd use the Header function to output a Location header.

header("Location: http://www.example.com/");
http://us2.php.net/manual/en/function.header.php

Or you could use META REFRESH and only output the meta tag if those conditions are met...

That would be the correct way to do it.

you cannot use a server-side scripting language to redirect pages after output has been written to the browser.

using javascript in this case would be your best option.

alternatively, if all processing and data validation is done server-side, you can use sleep to delay execution, and then use header to redirect.

How do you figure? There are a number of ways to do it, none of them incorrect. Just depends on the specifics (which he didn't go into very much).

thx guys, for some reason the Location nor Sleep worked. Location didn't do anything at all (as if it weren't even there) while Sleep delayed the processing of the entire page altogether, not dependent on where it was placed. I've found that php is a bit weird depending on how it was setup on the host and the version.

I decided to do the code processing on the output page (where it was going to be directed). I'm sure this is the way it's supposed to be anyway. Didn't know much about php before but I guess a little trouble goes a long way. Thanks.
