If the user truly has not made a selection, the $mt will be undef, and
your script will throw a warning:
if (!defined $mt) {
# etc
}
However, it is very difficult for the user to fail to make a selection
given a select element. It would usually require them to construct their
own form, or HTTP request by hand. If you want to test if they have
selected the "Choose type message" option, then you need to check if $mt
contains the data "0".
The length of "0" is 1 (since it is one character long), so (length($mt)
== 0) will always fail.
if (
(!defined $mt) ||
($mt eq '0')
) {
# Etc
}
