I have a query, that I have tested outside of PHP directly on SQL and still getting the same problem
The idea being that $currentArtist is sent through using the GET met
SELECT *
FROM events e
WHERE '$currentArtist' IN (e.event_artist1,e.event_artist2,e.event_artist3);
try
SELECT * FROM `".DBN."`.`events` WHERE
`event_artist1`= '".$currentArtist."' OR `event_artist2`= '".$currentArtist."' OR `event_artist3` = '".$currentArtist."'";
SELECT *
FROM `".DBN."`.`events`
WHERE `event_artist1` = '".$currentArtist."'
OR `event_artist2` = '".$currentArtist."'
OR `event_artist3` = '".$currentArtist."'
";
Hope this helps.
