I want to extract a piece of data for the logged in user from the Wordpress database, so that I can use it as a variable in another script. The data is the value in a key:value pair in the meta_value field.
Retrieving data from the Wordpress database seems confusing as all get out to me. I saw the $wpdb function, but after that I get lost.
Anyone here what can help with the SQL for that? I use MySQL on a Linux server.
