グループ化する前にテーブル(コメント)を並べ替えようとしているので、という一時テーブルを作成し、comm_sorted
タイムスタンプで並べ替えました。
ただし、それでも機能しません。
$sql = "
select images.id,images.image as imageURL, images.fid as userID, user.name as userFullName, images.comment as feedDescription, images.sharedServices, stores.name as customerName,
CONCAT('[',
GROUP_CONCAT(
DISTINCT CONCAT('\"',likes.uid,'\"')),']') as likes ,
CONCAT('[',
GROUP_CONCAT(
DISTINCT CONCAT('{\"userId\":\"',comm_sorted.uid,'\",\"comment\":\"',comm_sorted.comment,'\",\"timeStamp\":\"',comm_sorted.timestamp,'\"}') separator ','),']') as comments FROM images
LEFT JOIN stores on images.client_id=stores.id
LEFT JOIN likes on images.id=likes.feedid
LEFT JOIN (select * from comments order by timestamp DESC) as comm_sorted on images.id=comm_sorted.feedid
LEFT JOIN user on images.fid=user.id WHERE images.fid=:userID group by images.id, user.name, images.image, images.comment, images.sharedServices, stores.name order by images.Timestamp
DESC LIMIT $offset, $limit";
