HI all, I am building a php application and i am wanting to use notifications. At the moment i am just wanting to understand the methodology behind this. I dont necessarily have a use case for these notifications yet but i am going to base it off of the following: A user submits something to the database, another user gets a notifications that this has happened. I see the notifications being something appearing in the header bar (saying "you have a notification"...) I know that i will need to use ajax for this and JS/JQ but i am not really sure where to start with this. I have done some research and have come up a little blank. My main question at the moment is how does the submission of data to the database trigger the notification? As always and help here is appreciated. Kind Regards Adam
Good evening, I am working on a query at my office that is joining multiple tables in order to display a User notification (similar to facebook). The notifications are based on user department, access level, and position. I want to display all of the announcements filtered for the user that is in the CWAnnouncement table and the NotificationArchive Table where the NotificationArchive.Active is equal to 1 or if they have not made an entry in the NotificationArchive table. If NotificationArchive.Active is equal to 0 then I do not want it to show up in the query results. So far the user filter works but I am having trouble display the results based on who the user is and whether or not they have an announcement in the NotificationArchive table. I hope this make sense. Help would be greatly appreciated this will be my first major project for this company and I want to do a good job for them.
