Shared User Table Roles

安装

To set up multiple wordpress installations using the same database:

1. Install all wordpress installations using the same database, but using a
   different $table_prefix in wp_config.

   For example two installations with “eng_” and “nld_”.

2. Designate one wordpress installation as “primary”. All other installations are
   secondary

   For example the installation with the prefix “eng_”.

3. Install and activate this plugin on all secondary wordpress installations.

   In this example “nld_”.

4. On all secondary wordpress installations configure CUSTOM_USER_TABLE and
   CUSTOM_USER_META_TABLE in wp-config to use the tables (users and usermeta)
   of the primary installation.

   See below for an example

5. On all secondary wordpress installations, set SHARED_USER_TABLE_ROLES_PREFIX
   to be equal to the table prefix of the primary installation.

Primary

For example the relevant wp-config settings for the primary installation would
look like:

    $table_prefix  = 'eng_';

Secondary

For example the relevant wp-config settings for secondary installations would
look like:

    $table_prefix  = 'nld_';
    define('SHARED_USER_TABLE_ROLES_PREFIX', 'eng_');
    define('CUSTOM_USER_TABLE', 'eng_users');
    define('CUSTOM_USER_META_TABLE', 'eng_usermeta');
