Re: [PHP] 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:
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.

[PHP] implode errors if array empty
hi there,
i am using implode to get the contents of an array into a single variable:
$enterprises = implode(",", $enterprise) //enterprise contains the array.
however, if the array is empty (the user didnt select anything in the form),
the implode function errors out.
can anyone think of a way round this?
many thanks,
luke m.
