Actually – problem solved…. I believe there may be a syntax error in your code example file:
http://www.jqwidgets.com/jquery-widgets-documentation/documentation/phpintegration/php-server-side-grid-editing.htm
the $update_query string in your data.php file example has single quotes ( ‘ ) flanking the variable names (i.e., ‘LastName’ = …, ‘Title’ = …, etc.). Those single quotes aren’t necessary because that string is being processed by the subsequent mysql_query($update_query), and that query needs to read a straightforward SQL command line as simple text. The single quotes ARE necessary around the corresponding $_GET parameters however (i.e., ‘ “.$_GET[‘LastName’].” ‘ ), but not for the standalone fields in the SQL statement.
Once those single quotes were removed, the rest of your example works great…
many thanks,
