Page redirection

[Anon]

Hello I need some advise ......

I have a page say results.php that information is posted from form.php . The problem I have is sometimes people go to results.php and that submits a blank record.

I need to have results.php figure out if there was nothing posted not to submit anything and redirect to form.php.

I know somthing like this has been done before I just can seem to find a good tutorial or syntax examples to help me along.

Thanks-
K.

just check for the existence of one or more of the form variables with isset() and, if not, use header() to redirect.

Also - if you've already sent the headers to the browser then there are 2 other options that i know of:

1) Send a piece of javascript to the browser (n.b. some browsers do not support it) by doing this:

//note that we are CLOSING php tags here:
?>
<script>
this.location = "http://www.mysite.com/restofpath.htm"
</script>
<?

Note that you have to supply the full URL here.

2) Include the file that you want to redirect back to, e.g:

include("originalpage.php");

This will not work across domains.

Hope that's helpful
