php - How to redirected to current page after processing the code and its result on other page? -

i have email newsletter on mutual footer file whch displayed ove site, have email newsletter section in footer.

now want newsletter input email processed , and homecoming same page news letter has been subscribed. not have permission redirect form footer.php.

please suggest thought create happen

if understand correctly have footer on every page link this: (correct me if i'm wrong)

<div id="footer"> <a href="/newsletter/subscribe.php">subscribe newsletter</a> </div>

let's you're on page url

/article/20100924

and want go page after processing /newsletter/subscribe.php

as usual there several possible answers this.

if configured correctly there should $_server['http_referer'] variable in server array pointing page click originated utilize that, , after processing form set

header('location: '.$_server['http_referer']);

at end of /newsletter/subscribe.php

if don't trust $_server['http_referer'] right set originating page link url this:

<a href="/newsletter/subscribe.php?backurl=%2farticle%sf20100924"> subscribe newsletter </a>

php redirect
