SELECT * FROM (`events`) WHERE `contact_id` = 4 AND `check_in_date` >= '2014-09-14' AND `check_out_date` < '2014-09-25'

Answer 1

Make sure you use DATE('value') or DATETIME('value') whatever suits you. Also make sure formats are matching.

$this->db->where('DATE(column) <= ', 'DATE('.$value.')');
