Here is how to retrieve LOG OUT HASH for various purposes.

Many times we may need to use the LOG OUT HASH - Let's say, share a common logout between VB and non-VB pages?

Or perhaps serve as a unique ID?

Instead of including it into a config file thru PHP, why not use mysql instead? It is a centralised location for your web apps.

Requirements: mysql 5

Code:

Create  VIEW vw_usernamelist AS (select userid,username,

md5(concat(userid,salt,'<YOUR VB LICENSE CODE>')



) AS logouthash from user order by userid)

Usage:

Code:

select logouthash from vw_usernamelist where userid='12345'

How about just generate the ID dynamically with PHP? No need to query the SQL server. :)

PHP Code:


		
			
$logouthash = md5($userid . $salt . $license);

$userid is the user's id. $salt is the user's password salt. $license is your license number, not your customer number.

I opted for mysql style so that I will be able to do a query from db server directly. It will also be indepedent of any development language. Eg: A vb forum + integration with a non-PHP web scripting lang.

The code I posted is pseudo and can be adapted for different languages. Most languages will have an MD5 function built-in, and those that don't have scripts created for them.

Is this still the same method used to generate the logout hash? It seems that it is different now.

[edit]

ok, nm found the new 3.7.2'ish method
