使用外部数据库数据登录Wordpress

Question

I have a WP site and also have a external DB (means not WP DB) with users. The insertion process at that table uses the same algorithm as WP uses. What I'm need to do here is login in WP but using this external DB which is in the same host by the way. I check this links http://www.tyssendesign.com.au/articles/cms/connecting-to-external-database-from-within-wordpress/ and http://wordpress.org/extend/plugins/external-database-authentication/ and for the first is not what I'm want but for the second one is not compatible with WP 3+ and I'm using 3.3.1, any suggestion or docs or something else?

Answer 1

You can write your custom php script to connect to the external database that has your users table, and query the form fields submitted by the user against the table to authenticate.

You can use this as a reference to writing your php code: How do I authenticate a user in PHP / MySQL?
