The data records are always re-entered instead of updated

You will probably run into a syntax error because the values are not quoted.

From that error is looks as if you forgot to put a $ on your variable name on line 12.

Your update query does not have a WHERE clause, so it updates every single row in the table. Use a WHERE clause to restrict the update to a particular row. See examples in the MySQL tutorial: https://www.w3schools.com/sql/sql_update.asp

$query = "UPDATE `$dbname` SET  name='%s', url='%s', short='%s', game='%s' WHERE name;";

If that works, it probably will update any row which has a name.
