Hi David,
You cannot call empty() on a function or class method like that. From
the manual:
Note: empty() only checks variables as anything else will result in
a parse error. In other words, the following will not work:
empty(trim($name)). - http://www.php.net/empty
You should assign the result of $rs->Fields(22) to a variable before
calling empty() on it, or use a class variable access to check it, or
check it first within the class and have Fields() return a suitable
value if needed.
Regards,
Torben
