I am trying to use PHP to pull information from a mySQL database, as well as offer an "Add More" button through the use of JavaScript. I'm able to put the new information into the database and I am able to pull the information out of the database to show. However, I am unable to figure out how to delete the information that's pulled from the database when I hit the delete button beside it (line 138 below). Any thoughts or ideas?
Thank you in advance!
