Support » Fixing WordPress » Linking User Database

  • I have many sites that are linked together as a network. I want to know if there is a way for me to make it so when someone registered on the main blog (Spike Network) they will be registered and will be able to comment on the other blogs (Whatever Tech, Negative Horizon, Anthony Radio).

    Is this possible? Thanks!

  • Can anyone help?

    No, WordPress has no inbuilt ability to do that, but that’s not to say it can’t be done with a hack or a plugin.

    Somebody will have to write it though… 🙂

    I knew that there was no plugin, but I wanted to know if I could do it by editing the code or something. Thanks.




    As discussed in IRC, the fact that you have seperate databases for each blog makes this complicated. If all the blogs were using the same database with unique table prefixes, it ought to be easy to write a plugin to override the $wpdb->users table definition to point to the canonical user database.

    As it stands, your best bets are to review the options at Installing_Multiple_Blogs. Alternately, you could back up all your sites, and import them into a new, shared database using table prefixes, and then use the plugin mechanims described above.
