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.
