fullcalendar adding events from mysql json - adding eventClick returns blank page

Answer 1

Probably this:

mysql_db_query

should be:

mysql_query

making it like this:

$check = mysql_query($sql) or die(mysql_error());

Make also sure that you put these lines on top of your script to see if there are any errors coming up:

ini_set('display_errors', true);
error_reporting(E_ALL);
