The program below contains various error messages to be displayed under certain conditions. These conditions are found through PHP code, after which the necessary JQuery script is echoed in PHP to make the messages appear.
At first, all messages in the .warning class are hidden. Then, if a certain condition is met, particular ids of this class are shown. Below is the relevant code.
<?php require_once 'connection.php'; ?>

However, the objects with particular IDs are not actually shown. Does anyone know why this may be? Thank you.
