OT: Restrict Access to page

Report · Oct 15, 2006

If I'm going to do this manually, is there anything I need to do *other*
than to check on the existence of the session variable?

Thanks, David. Why on earth does the DW SB for that generate so much code?

Regarding my previous question - these lines inserted by DW on pages that I
want to restrict access on are causing things to hang -

if (!isset($_SESSION)) {
session_start();
}

Do I need to have that on each such restricted page?

Yes, of course, if you want to use a $_SESSION variable, you must
initiate a session.

You don't need the conditional clause. That was added to Dreamweaver 8
at my suggestion because Dreamweaver server behaviors that rely on
sessions all insert session_start(). If you have two on the same page,
it generates a warning message.

For a manual restrict access to page, this is all you need:

<?php
session_start();
if (!isset($_SESSION['name_of_session_variable'])) {
header('Location: http://www.example.com/login.php');
exit;
}
?>

The Dreamweaver restrict access to page SB checks other things such as
access level. It also adds a query string to the redirect URL, so that
the visitor can redirected to the same page after successfully logging
in (as long as that option is selected in the Log In SB).

Thanks, David. I'll give that a try. I'm not sure why it's making things
hang, but when going to one of those pages, I get a timeout error....

The other option, if this is a set of pages in a single directory on an
Apache server, is to restrict access to the directory using .htaccess and
.htpasswd.

How crucial is the exit; line, David? I have to admit I haven't been
using it in my code. And I've been using a relative link too - time
for some search and replaces I think.

The KISS principle today is often used by software developers,
meaning the software should be designed in the simplest way,
avoiding creeping featurism.

Yebbut it works fine without exit and with a relative link. Anyway, as
usual a trip to the PHP manual explains all. Such a good resource -
can't wait for someone to transfer it to audio so I can put it onto my
iPod! How about it, DP? :-)

Without exit, there's a danger that the rest of the script will be
displayed. Using exit guarantees that the script finishes there.

Relative links work fine, but they're frowned upon by the HTTP police.

Oh, yeah. That'd keep me off the streets for a few Sunday afternoons. ;-p

If the redirection is the last thing in the script (which it often is) then
you won't notice the 'essential' character of that exit; function. But -
embed the redirection in the middle of the script and you'll bada bing right
out the window....
