MySQL - Trigger for updating same table after insert comparing the text - mysql

Question

Need Help with MYSQL Trigger with IF TEXT contains condition
Here's what I'm trying to do on MYSQL:
When there's an update on the table (i,e) when the "status" is changed from 'open' to "closed", i want to update date_closed to current date.
Trigger with if condition {could not get it to work}
create TRIGGER update_close_date BEFORE UPDATE ON issues
FOR EACH ROW
BEGIN
if LOCATE('closed', NEW.status) !=0 THEN
SET new.date_closed = CURRENT_DATE;
end if;
END;
Table Structure
CREATE TABLE `issues` (
`id` int(10) NOT NULL,
`project_type` varchar(100) NOT NULL,
`assessment_name` varchar(150) NOT NULL,
`issue_title` varchar(200) NOT NULL,
`description` varchar(1000) DEFAULT NULL,
`severity` varchar(10) DEFAULT NULL,
`status` varchar(25) DEFAULT NULL,
`found_on` date DEFAULT NULL,
`target_date` date DEFAULT NULL,
`app_support_contact` varchar(100) DEFAULT NULL,
`manager` varchar(100) DEFAULT NULL,
`date_created` datetime DEFAULT NULL,
`date_updated` timestamp NOT NULL DEFAULT current_timestamp() ON UPDATE current_timestamp(),
`date_closed` date DEFAULT NULL,
`reminder_count` int(5) DEFAULT 0,
`escalation_count` int(5) DEFAULT 0
) ENGINE=InnoDB DEFAULT CHARSET=latin1;
