i have a table with 4 text field columns. My problem is when i fill in any text to the first, second or third column, the fourth column has to automatic fill with the user's login username. Can anyone help me on getting the fourth column to be automatically fill with username when any text is enter to the first, second or third column? And if the value of first three columns is delete, the username of the fourth column should delete automatically. Thanks a lot for the help or advice.
If you're trying to get information out of a database, you will need AJAX for that. Is that what you want to do?
