Question

As I mention in the title, I’m doing a request for latitude and longitude within a ‘bid_userloc’ table … but I need to combine information from the ‘wp_usermeta’ table …

SET @centerLat = '48.531157';
SET @centerLng = '-123.782959';

SELECT *, ( 3959 * acos( cos( radians( @centerLat ) ) * cos( radians( lat ) ) * cos( radians( lng ) - radians(@centerLng) ) + sin( radians( @centerLat ) ) * sin( radians( lat ) ) ) ) AS distance FROM bid_userloc HAVING distance < 25 ORDER BY distance LIMIT 0 , 20

And using the user_id that comes in from the SELECT *, I need to get some user data from the wp_userdata table that looks like this:

id
meta_key
meta_value

For example, I need the meta_value of meta_key “nickname” … as well as a number of others, but once I see how it’s done for one, I can add more.

I really appreciate it!

Try this, with distance replaced with what you originally had, and something else replaced with something real:

SET @centerLat = '48.531157';
SET @centerLng = '-123.782959';

SELECT bid_userloc.*, distance, nickname.meta_value, something_else.meta_value
FROM bid_userloc
LEFT JOIN wp_usermeta AS nickname 
    ON nickname.userid = bid_userloc.user_id 
        AND nickname.meta_key = 'nickname'
LEFT JOIN wp_usermeta AS something_else 
    ON something_else.userid = bid_userloc.user_id 
        AND something_else.meta_key = 'something_else'
HAVING distance < 25
ORDER BY distance 
LIMIT 0 , 20
