Wordpress users and usermeta - joining multiple rows in one table to one row in another table

Question

I want to create a view from both the wp_users and wp_usermeta tables so that I can query rows in the view from an external application. Basic auth details are stored in wp_user

Answer 1

$sql= "SELECT
       u1.parent_id,
       m1.meta_value AS headline,
       m2.meta_value AS profilephoto
       FROM wp_vandor u1
       JOIN wp_usermeta m1 ON (m1.user_id = u1.child_id AND m1.meta_key = 'headline')
       JOIN wp_usermeta m2 ON (m2.user_id = u1.child_id AND m2.meta_key = 'profilephoto')
       WHERE m1.user_id != $currentuser_id";

$classifieds = $wpdb->get_results($sql);

foreach ($classifieds as $classified) { ?>
     
profilephoto; ?>
     
headline; ?>
