Hi,

the value of iid comes from the URL-request-string. I.e. &iid=0
If I test of the emptyness of $iid, empty($iid) returns FALSE, but $iid is not empty.

if (empty($iid)) {
$iid = '5.1';
}

The test "if ($iid == '') returns the right value.

regards,
Carsten

I suggest you turn your attention to the PHP manual.
(Though I admit that the fact that empty() returns true for 0 and "0" could be stresse more in the manual page.)

"empty($iid) returns FALSE, but $iid is not empty."

$iid is NOT empty, so it indeed returns false... :-)
