Re-direct to an error.html

Members visiting out Club Web Site can enter their 'Member Number' into a textfield and the below PHP scrip re-directs them to their own member.html

I want to know how I can re-direct them to an error.html if anything other than a member number or an incorrect number is entered.

Any help please

<?php

$host  = 'http://www.mysite.co.uk/member_secure/';
$uri   = 'member_files/';
$memberID = $_REQUEST['member'];
$extra = $memberID.'.html';

header ("Location: $host$uri$extra");
exit;
?>

PHP:

 

does your memberId stored in a database? or its autogenerated?

 

It's neither stored in a database nor is it autogenerated. All the members HTML pages are in a folder call 'member_files' and the PHP selects them. Is there a coding which can be added to say that if the member.html isn't there then goto error.html.

 

look in your other thread, I gave you something which I think is what you want
