SQL queries from an external DB in WordPress

3 Views

Actually I have a php website in my hosting. Now I am personalizing a WordPress theme to replace it. It’s all ok for now, but the old website has a built in function to connect to another database with a token. This connection is only to get some data.

Can you tell me how to implement this in my new wordpress theme?
Did a wordpress plugin exists for this?

Thanks

  1. The easiest way to connect wordpress to a second database (without a token) is to add this little piece of code (replacing strings by your connexion data) :

    $wpdb2 = new WPDB( 'remote_user', 'remote_password', 'remote_db', 'remote_server');

    Then you can use this new object to query anything that you want to, just like the main $wpdb object. You can use this on the function.php file of your active child theme (or theme).

    I think that maybe there is some plugins, for this kind of purpose… You will have to search.
