I have users as they upload images comment like a persons profile I want the person whose post was like commented or any other action to be notified that this person likes your photo

The way Facebook does it

Answer 1

There’s many ways to do it, one of which is to have a column in the table titled new_notification that will tell you if the notification is new(read by the user or not). So, for example, if a person likes another persons picture, in the table that column will have new_notification set to Y. When the user who’s picture was liked logs into the website, you search for all rows where new_notification = Y do a count and show the number of notifications like facebook does. Once the user has seen the notifications or opened the notification bar, go through that table and set all the rows with new_notification = Y to 'N'.
