I think this would work. The "disabled" attribute can be set to a true/
false value in script. Since keyup can be an expensive thing, I just
attached handlers to the two fields you needed to monitor rather than
the whole form; you could attach it to the form if you prefer. Rather
than set the initial value, I just triggered the handler to do its
thing on the initial form values. I wasn't sure why you used .text()
instead of .val() for the textarea, is there some kind of bug
in .val() for textarea? Also, remember that any post content (even a
bunch of spaces) will pass this test. You might want to do a bit more
validation on the input if it's important to the page.
$('#post_name, #post_content').keyup( function () {
$('#post_submit').attr('disabled', !$('#post_name').val() || !$
('#post_content').val() );
}).trigger("keyup");
