Thanks,
Now I have a start point. I need to extract the logged in user as input to a php for add the filter to a database where the user-id tell that user can edit his own row but only view other members.

Take care / Lars

thanks for this, it definitely got me in the right direction. however, wp_login is depracated now. wp_signon is what should be used:

Lars, thanks for sharing this work. I’m using it as part of link that allows users of in-network sites to be automatically logged in from site to site.

Thanks and keep it up

I think there are two approaches to doing this, either should work:
1. include a URL variable on the link coming from the domain you want to autologin from, e.g. www.yourdomain.com/?auto=1
OR
2. Which is less reliable since not all browsers will provide it, try getting the URL from whence a visitor is coming, in PHP, use:
if($_SERVER['HTTP_REFERER'] == ‘domain.com’ ) {
…
}

Then proceed to input the autologin script above

Hi,
I want to autologin in everybody that click on links (that lead to my site) on a certain URL. So, If a link to my page is published on http://www.domain.com the person clicking it should be loged in autoamtically with a certain user.

If the same link is somewhere else tha one who clicks it shall not be logged in.

Any suggestions on how to do this? Possible?
many thanks.
/Ola

Hi!
I hoped this would solve my problem, and it partially did, but when i execute this piece of code i get the following errors:
———————————————–
Warning: Cannot modify header information – headers already sent by (output started at /home/…./wp-content/themes/idream/header.php:7) in /home/…./wp-includes/pluggable.php on line 690

does it depend on the theme? i tried 3 or 4 themes and it happened with all of them..

am i doing something wrong? thanks!

Thank you so much for this, Lars, it was exactly what I needed. I too was trying to sync WordPress accounts with accounts on another server, so I needed this on a custom registration form.

Just stopping by to say thanks, keep up the great work!

Hi Lars
meanwhile I found, that $current_site and $current_blog are only the half of the truth!
Both should be objects like:

class site {
public $id = 1;
public $domain = “domain.net”;
public $path = “/”;
public $blog_id = 1 ;
public $cookie_domain = “domain.net” ;
}

$current_site = new site() ;

that does the trick of autologin in truth and also works for user creation scripts an similar for particular blogs.
Sorry for dealing with part of the truth

cheers
Peter

thanks for your great autologin example!
for login in multisite-WordPress 3.0.1 you need additional information
such as $current_site and $current_blog to auto login

cheers
Peter

$current_site = array(
“id” => 1 ,
“domain” => “domain.net” ,
“path” => “/” ,
“blog_id” => 1 ,
“cookie_domain” => “domain.net” ,
) ;
$current_blog = array(
“blog_id” => “1″ ,
“site_id” => “1″ ,
“domain” => “blog.domain.net” ,
“path” => “/” ,
“registered” => “2010-09-04 23:44:04″ ,
“last_updated” => “2010-09-04 23:46:09″ ,
“public” => “1″ ,
“archived” => “0″ ,
“mature” => “0″ ,
“spam” => “0″ ,
“deleted” => “0″ ,
“lang_id” => “0″ ,
) ;
require(‘wp-blog-header.php’);
$user_login = ‘admin’;
$user = get_userdatabylogin($user_login);
$user_id = $user->ID;
wp_set_current_user($user_id, $user_login);
wp_set_auth_cookie($user_id);
do_action(‘wp_login’, $user_login);
