Answer 1

I don't need the code, you do. :O) Read the instructions
below. Replace
the parts of the code that are bad with parts of the code
thar are good.
Let's look at the tutorial/post, posted below in it's
entirety from
http://friendsofed.infopop.net/2/OpenTopic?a=tpc&s=989094322&f=8033053165&m=324102421&r=32 4102421#324102421.
1. Log In User needs changes in two places, plus the removal
of three
lines. Find the following lines of code
$GLOBALS['PrevUrl'] = $accesscheck;
session_register('PrevUrl');Replace them with
$_SESSION['PrevUrl'] = $accesscheck;2. Then find
$GLOBALS['MM_Username'] = $loginUsername;
$GLOBALS['MM_UserGroup'] = $loginStrGroup;Change them to
$_SESSION['MM_Username'] = $loginUsername;
$_SESSION['MM_UserGroup'] = $loginStrGroup;
3. Finally, DELETE the following lines
//register the session variables
session_register("MM_Username");
session_register("MM_UserGroup");That's it. You're done with
your Login
form. You know need to replace a few lines in your logout,
but we'll wait
on
that.===========================Article========================I
have
discovered there is a serious bug with the Dreamweaver MX
2004 User
Authentication server behaviors when used in conjunction with
PHP5.
Basically, the problem is that the DW server behaviors use
obsolete code
that appears to work with PHP4, but breaks once deployed on
PHP5 (with
register_globals set to the default off setting).
I have notified Macromedia of the problem, and they have
logged it as a high
severity bug, but have given no indication as to when a patch
will be
issued. Fortunately, the solution is easily fixed by hand.
The server
behaviors affected are Log In User and Log Out User.
Log In User needs changes in two places, plus the removal of
three lines.
Find the following lines of code
$GLOBALS['PrevUrl'] = $accesscheck;
session_register('PrevUrl');Replace them with
$_SESSION['PrevUrl'] = $accesscheck;Then find
$GLOBALS['MM_Username'] = $loginUsername;
$GLOBALS['MM_UserGroup'] = $loginStrGroup;Change them to
$_SESSION['MM_Username'] = $loginUsername;
$_SESSION['MM_UserGroup'] = $loginStrGroup;Finally, DELETE
the following
lines
//register the session variables
session_register("MM_Username");
session_register("MM_UserGroup");
In Log Out User, locate these two lines
session_unregister('MM_Username');
session_unregister('MM_UserGroup');Replace them with
unset($_SESSION['MM_Username']);
unset($_SESSION['MM_UserGroup']);
NOTE: There is NO need to do this if you are still using
PHP4, and not
experiencing any difficulties with User Authentication.
However, it does
affect the instructions for Chapters 14 and 15 of Foundation
Dreamweaver MX
2004 for anyone switching to PHP5.
