I'm just a php beginner.
So please be patient with my stupid questions.
What am I missing in this code that causing the function can’t update the textarea?
Update button erase the old information from mysql database and replace it with nothing. Basically it can’t read what is inside the Textarea box. Why??
Read the highlighted code.
<?php
include ('./includes/header.html');
include( '../mysql_connect.php' );
