I got a text field for entering the new categories and submit with ajax ..
My script is working but everytime i submit new category mysql is creating one row to hold single category name .
I would like to create something like this eachtime when i add a new category the same single row should get updated
Id. User id. Category
1. 23. Personal , shopping , others +
So everytime i update a category name the row should be updated with the comma separated value . And also i would like to fetch the result in a select box
