Hi.
I have a php webside with a guestbook and I want access to the guestbook
only via the homepage.
How can I modify the index.php of the guestbook to prevent access from
outside the website?
Any hints ?

Regards, Hans

Check the $_SERVER['HTTP_REFERER'] that it has a value that is a page on
your site, but keep in mind that this can be spoofed (spammers has no
problem at all to post automatically in your guestbook) and legitimate
users may not be able to post as their firewall filters ref-addresses
without them knowing about it.

You can't reliably. And whatever you do will make it harder for valid
users.

For instance, you could set a session variable in your home page, then
clear it in any other page on your site. Check for it in your guest
book page. If it's not set, don't allow the page to be loaded.

But it also means search engines won't be able to access your guest book.

The real question is - what problem are you trying to solve? If it's
guest book spam, this may some, but won't stop it.

It's not because of guest book spam, but my pagecounter tells me that
several times a day the guest book gets hits from "accidental" visitors.
Ok, it's not a big deal. I leave it the way it is.
Thanks for your responses.

Or, maybe someone has a link to your guestbook page.
