Login in Wordpress MU with Joomla users

Bleach - Bleach - if you can't fight yourself, believe in yourself.

Well yeah, been coding again... That's why I've been out from posting for a while...
I'm no code guru at all, yet I was assigned with some friends the task of integrating a Joomla 1.0.13 user database with Wordpress Multi user, or WP MU. I haven't slept all weekend trying to accomplish this. I hate coding and so, I'm sharing this crap to anyone interested. I'm not giving support tho, cuz these CMS tend to change and I'm not changing this code unless I really need it.
Been coding and Googling all weekend trying to solve it and found a very useful plugin here. Made by Eugene Heriniaina AKA Hery. All the credit should go to him.

Thanks a lot to DiegoH and JoVi, thanks to them this coding hell is now over.

Couple of issues to consider:

- Since version 1.0.13 of Joomla there's a new hash for login processes. We based on an md5 check used for new users in joomla in the joomla.php login function...
- on the admin page in WPMU (Panel- Options- Mysql Auth) you will want to specify the database address and a query similar to the following: SELECT username, email FROM jos_users WHERE username = '%{user}'
- This hack checks in joomla's db and logs into wpmu with joomla's users
- If the user exists on joomla andnot on wp, a new user is created in WP, subscribed to the main blog. If you want to create a default blog you can add it via code with:
$blog_id = wpmu_create_blog($newdomain, $path, $username , $user_id, $meta);
do_action('wpmu_activate_blog', $blog_id, $user_id, $password, $username, $meta);
$meta = apply_filters('signup_create_blog_meta', array ('lang_id' => 'en', 'public' => 1));
- If the user is in both joomla an wpmu, the user is updated with data from joomlas database and logged in to the panel

- Be sure to ALWAYS send a STRING NON MD5 password to the wp-login function in the plugin... Via cookies, post variables, or session variables. Whatever, as long as $password is not hashed and all info is correct it should work fine.
You can accomplish this by modifying on /wp-includes/pluggable.php and in wp-login.php... all passwords that are sent to wp-login should be changed.
You can send $_POST['pwd'] to the wp-login function and it should work.
All files have been uploaded to a RAR.
- Be sure to redirect the user to the panel by default


- That's it. Enjoy and hope it works for you and saves you tears.

EDIT:

- Also, to install a WPMU installation inside a joomla portal, just install your WPMU in a SUB FOLDER in your FTP server. That way you get no weird issues.
Say, if you have your joomla installed in www.mysite.com/
you should have your WPMU installed in www.mysite.com/blogs/
(you can name it as you wish), at least that's how they solved it where I was working.
