Re: implode errors if array empty

Hello, I suppose the $enterprise variable doesn't hold an empty array but is not defined and because of this you get the error. Test with the following example: <?php $array = array(); $comma_separated = implode(",", $array); echo $comma_separated; ?> It does not send any errors back. If you substitute $array = array(); with $array = ""; you'll get a woarning: "Warning: implode(): Bad arguments. in temp.php on line 4". Just have in mind that when posting multiple select fields and no options are selected - you simply have no corresponding value in the _POST array (or in the $enterpise variable if you're using register_globals). There's no empty array but nothing defined.
