Bug on query

I think you have a bug in your scan postmeta query.

This is the current query:

SELECT meta_value FROM wp_postmeta
			WHERE post_id = ?
			AND meta_key = '_thumbnail_id' OR meta_key LIKE '%gallery%' OR meta_key LIKE '%ids%'

This query will fetch all rows matching post_id AND meta_key = ‘_thumbnail_id’. It will also fetch every row with meta_key like gallery or ids without taking into account the specified post_id.

I think the correct query will look like this:

SELECT meta_value FROM wp_postmeta
			WHERE post_id = ?
			AND (meta_key = '_thumbnail_id' OR meta_key LIKE '%gallery%' OR meta_key LIKE '%ids%')
