thx. But still only "OK" return Value.
I have
inetc:

ost /NOCANCEL /TOSTACK /SILENT "http://www.xxx.com/Addr.php$Parameter$URL" $0 /END
Pop $0 # return value = exit code, "OK" if OK
MessageBox MB_OK "info: $0"
still ok ..also if php return false....Here is the php code:
if($body==null)
{
$query="INSERT INTO #__xxx_active (OrderID) VALUES ('".$OrderID."')";
$db->setQuery($query);
$db->execute();
echo "true";
}
else
echo "false";
