andrei,
yes, it should have been like that. now handle_alias() takes care of
it.
thanks for the explanation. i have to say though that as a normal
programmer, i'm not used to such behavior.
in order to avoid programming mistakes like that, could it be possible
to produce a error message if such a test is attempted, i.e., test on
string valued pvar?
-- juha
$var(tmp) =
$(ru{uri.param,alias});
xlog("L_INFO", "Alias param is <$var(tmp)>\n");
if ($var(tmp)) {
xlog("L_INFO", "Alias param is <$var(tmp)>\n");
$du = $var(tmp);
^^^^^^^^
shouldn't it be $du = "sip:" + $var(tmp) ? why does the
test
if ($var(tmp)) {
fail to figure out that $var(tmp) has value?
You should use if ($var(tmp)!="").
if ($var(tmp)) works only for integers. If $var(tmp) is not integer and
not a string of the form "1234", it will evaluate to 0 in an integer
context. The if() it's an integer context (no boolean context in sr).
