i am trying to display and update read/unread messages. I have a column in database msg_read, that is by default has a value of 0. 0 means read, and 1 means unread. Need guidance to update the status when the message is read. With the guidance of Mr. Andre, the unread messages are showing Bold now, but when read, messages become normal (not bold).
