Hi,I am trying to access a database using the a html 5 select field for a mobile app for college. I have been trying to use the w3schools tutorial found here:http://www.w3schools.com/php/php_ajax_database.aspI have essentially copied the tutorial exactly but I keep getting the error:Warning: mysql_fetch_array() expects parameter 1 to be resource, boolean given in C:\xampp\htdocs\ajax\getuser.php on line 25I cant actually reproduce the tutorial without errors which is very frustrating as I need to be able to get this to work within a html 5 phonegap app. Any help would be greatly appreciated.Many thanks
