[wp-hackers] Talking to Ajax

[Kevin Stover]

Hey Dino,

I use ajax quite a bit in many plugins. One of the things that I noticed is
you have closed-**postboxes in the first part of your add_action, and
closed_postboxes in your second half. Make sure that your ajax request uses
the right one. I've done silly things like that before. Secondly, make sure
that you put a "die();" at the end of your called php function
closed_postboxes(){}.

Hope that helps,

Kevin
