No.

All of those $_POST elements *ARE* arrays because the HTML has
NAME="year[...]"
For pre-existing slots, they have a valid slot_id in the array index.
For the one NEW item to be inserted, I used the key [NULL] which in HTTP
turns into 'NULL' as an index into the array.
In other words, if there were 3 pre-exsiting slots, and the user fills in
the "NEW" date to add, and I did:
var_dump($_POST['date']);
I'd get something not unlike:
array('1'=>'2005-04-01', '2'=>'2005-04-04', '3'=>'2005-04-05',
'NULL'=>'2005-04-06');
Thus, $year = $_POST['year']; gets me the whole array, and then $year =
$year['NULL'] gets me the NEW year they are asking me to insert.
I dunno why this seemed so confusing, but it makes perfect sense to me.

Yes, <?= is not portable to a site that doesn't have short_tags ON. No, I
don't care, since I'll NEVER move this code to another host/server.
Note that echo takes multiple arguments.
Note that the parens I use are to group the second argument to the echo
statement. The second argument being a valid ternary operater statement.
So there are no error messages because it *IS* syntactically (and
logically) valid.
The FIRST thing I do on any new server/site is crank up E_ALL for the errors.
