Unless you send bad HTML or someone's messing with their submit data,
it's very unlikely that someone won't have made a selection. In that
case, you want to check the "truth" of the selection value, not the
length. As previously noted, the length of "0" is 1, but you really
don't care about that. I would leave the value as 0 or set it to the
empty string and write the condition like this:
if ($mt) { ... }
