TIL you can share multiple users between WordPress installations

POSTED ON:

TAGS: wordpress cms user-tables

Imagine you have multiple WordPress Installations.

What sucks is having to create 4 separate accounts to access each one.

Additionally, because there's no connection, a user can hypothetically create a:

  1. John Jones (jjones@email.com)
  2. John J Jones (johnjjones@email.com)

as two completely separate entities.

WordPress has thought of that!

You can use the same userbase for all your blogs on the same domain by defining the CUSTOM_USER_TABLE and optionally the CUSTOM_USER_META_TABLE constants to point to the same wp_your_blog_users and wp_your_blog_usermeta tables.

<?php
// in wp-config.php
define('CUSTOM_USER_TABLE', 'main_user_table');
define('CUSTOM_USER_META_TABLE', 'main_user_meta_table');
