RE: [PHP] Re: [Repost] Getting rid of "Web page has expired" (POSTDATA Error)

[SNIP] Now one thing bothers me: how do you redirect in step 4 if you have shown the form in step 3? How do you avoid a "Cannot modify header information - headers already sent by ..." error message? Nicolas Verhaeghe E-mail: nicolas@whiteecho.com Phone: 602-490-8000 [/SNIP] Nicholas, As long as you haven't outputted anything from your script after the form post, you can redirect just fine. Step 3 and Step 4 are two different steps. You need something like this: if (isset($_POST["btnSubmit"])) { // validate form } if (!$form_passes_validation) { // show form } else { Header("location: "); }
