SQL Query - Adding Values Into Multiple Unique IDs

Question

I have a Wordpress site that needed to have 9,000+ users imported to set up a Directory Listing. I imported them from an existing MySQL (non-wordpress) database and everything imported just fine. Usernames, passwords and display names (MD5 hashed, but I tested and WP will change the password to phpass on the first login).

Thing is... They have all been imported with a user role of NONE. I need to change this to Subscriber. Now, I can get into my phpMyAdmin and I can see the field row value 'wp_capabilities' in the wp_usermeta table. I can see that:

admin accounts = a:1:{s:13:"administrator";b:1;}

Subscribers = a:1:{s:10:"subscriber";b:1;}

I can also see that there are many values entered into each user_id. Question is? How can I write a bulk MySQL command to add in the value wp_capabilites='a:1:{s:10:"subscriber";b:1;}' into each user_id except 1, 2 and 3 ie. the newly imported users?

Thanks in advanced!

Answer 1

Try this:

UPDATE wp_usermeta SET wp_capabilities="a:1:{s:10:'subscriber';b:1;}"  
WHERE user_id not in(1,2,3);

Or

UPDATE wp_usermeta SET wp_capabilities="a:1:{s:10:'subscriber';b:1;}"  
WHERE user_id > 3;

Answer 2

I actually ended up using this query:

`UPDATE wp_usermeta SET meta_key = 'wp_capabilities', meta_value = 'a:1:{s:10:"subscriber";b:1;}'  
WHERE user_id > 3

Because the table had no data for the imported contacts, this is the only value under meta_key and meta_value for all records other than my administrator accounts.

Can anyone see why this would be incorrect?

Thanks!

    function update_usr_meta(){
    $users = get_users();
    if( !empty($users) && count($users) > 0 ) {
        foreach( $users as $u ) {
            if( $u->ID > 3 ) {
                update_usermeta($u->ID, 'wp_capabilities', "a:1:{s:10:'subscriber';b:1;}");
            }
        }
    }
}
add_action('init',  update_usr_meta);

Run this function once and all the users will be updated. Hope this helps.
