I suppose that, as well as updating the database when I click the link, I
could also update a CSS toggle, but I'd really like it to be deciding
whether to toggle only based on the flag in the database.
So:
// check database
if ($toggle == 1)
{
<textarea>...</textarea>
}
else
{
<textarea disabled>...</textarea>
}
This is called every time the page is refreshed, of course, but if the
database is changed afterwards, the form doesn't know. I would like some way
of continually checking in the background whether $toggle is 1 or 0, and
update the form appropriately. I assumed AJAX was the way to go.
Perhaps I'm making this more complicated than it needs to be, but there is a
reason why I want to store the state of the toggle in the database (as
opposed to simply using a javascript on/off snippet) as I use this
information in other places in the code.

This sounds too obvious, so I've probably misunderstood your question -
but surely it is just a matter of toggling the CSS 'display' attribute?
