HELP a newbie.

[Anon]

I'm pretty new to PHP and i'm not sure how to access a variable passed through the browser(ie: visible through the URL).

Here's the page that has the link (the referrer).
<a href=\"buddyadded.php?CUserName=$row>CUserName\">Add $row->CUserName to my buddy list</a>

The page that should access the variable that was passed (the referree).
I tried to print the variable passed by going:
print "$row->CUserName"
AND I tried
print "$CUserName"

However, instead of accessing the variable passed, it accesses the CUserName that was saved as a session.

How do I get to this variable?

Thanks,
Mike

$HTTP_GET_VARS["CUserName"];

Or change the name of the variable to something that you aren't storing in a session and you can use:

print "$CUserName";

Or access the $CUserName variable before you call session_start() and you should get the variable that came from the previous page.

By default, the rules are:

Sessions trump everything, then
GET
POST
COOKIE

In other words, you can set a cookie and then override it with a GET, but you can't override a session variable.

It is possible to change some of this behavior by altering php.ini. See the manual for details.
