Autologin a WordPress user in your PHP script

I don’t think there would be a security issue as such, obviously you need to secure your own login-system, but if you already do that, the data you send to WordPress should be fine.

You should also note that by maintaining a separate user-login system, you have two databases you need to keep synchronized, making sure to add, modify and delete users in both.

Although it is clearly your own business, I suggest to take a look at fully using WordPress as your userdatabase. I do that on linklaunder.com (which is not active at the moment, unfortunately), where I use a few plugins to ensure a double-opt-in system where users actively agree to the disclaimer, privacy policy, etc. This is through the use of the plugin “Register Plus”.

It is very easy to use a bit of php-code in your template files, to use WordPress to process user-level, and provide individual user data to logged in users.

Just my suggestion, let me know if you need some help, should you choose to go that direction.

Thank you for visiting, and leaving a comment! 🙂

Hello! this is the only thing close to what I need so thank you very much for using the time to write it!

I have an free script, me and some friends developed, and I wanna ask you, it it posible to build an external user system based on WordPress use system?

Let’s say you have /root script and /root/u wordpress.

Can I loggin user in WordPress and call user data in script? Like session, name, chack if it’s legged ?

Thank you very much for your time answer this!

Thank you for posting this script it has helped out alot. One question though…

I am using this dynamically, grabbing the users username from the headers which has been authenticated from a different source. I’m looking for a script that will automatically add the user as a subscriber if they are not already in the DB. Anyone have a script that will accomplish that?

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
