  1. Error location: Chapter 7, page 205 Incorrect text: } else { //Development (print the error) Corrected text: } else { //Production (email the error)
  2. I am trying to create a form that includes two drop-down select menus that each display records from their respective table from a database. Each drop-down menu uses the require statement to call my mysqli_connect script as does the overall form when it is called to insert the records, making 3 total require statements. When I tested the page it worked on the testing server but now I receive Constant DB_NAME, DB_HOST, DB_PASSWORD, and DB_USER already defined errors now that the site is live. I have tried using require_once on one, two , or all three calls instead of require but then one of my drop-down menus stops working and seem to get the same message. Any help would be appreciated.
