Some of my attempts to pass session information along as the user moves from page topage works correctly. And others fail for reasions I don't understand. All help appreciated.

Working code follows. The ipassed info is in the url as "?id=7" or other correct id number.

href="/updatecontactscurrent_members.php ?id=<? echo $id; ?>">Update</a></font></td>

And the following code obtains the passed info correctly:

$id=$_GET['id'];

The failing code is as follows: The passed info is in the url as "?UserID=<? echo $UserID;?>"

<tr><td align left>
<a href="http://localhost/workinglogoutsession.php?UserID= <? echo $UserID;?>">Members Logout</a></td></tr>

And the following code obtains the passed info correctly but the info is wrong!

$UserID=$_GET['UserID'];

Any ideas where I screwed up?

remove the space between UserID= <?

The browser will encode the space as %20 giving you wrong info

Removing the spaces had no affect on the result. Are there any tutorials available specifically focused on navigation and site security? This sometimes works...sometimes doesn't... is driving me nuts!

Double check your passed vars, on the landing page write:

PHP Code:

print_r($_GET); 


This will display the entire contents of the #_GET vars, make sure is is the data you are desiring.
