Remove and change database results using ajax

We need to fix two small problems. Everything has been done in the webpage (design,database structure, mysql sentences,...) but we need some few lines of code that we don't know how to insert them, so here are the problems: 1. We have a table showing database results and we want to remove those database results using a confirmation popup (bootstrap modal) and we would like to pass database variables to the popup and remove all the data from the popup. 2. We have a page where we show a table with a hidden status for a user (all the info is showing this "????") and when that status change in the database ,make all the info visible to the user in that page. More details will be explained when the project be awarded We know this is not too much difficult for a developer and almost all the code is done, so we will take into account the lower bids.
