Flash Variables to Wordpress Comment

programming
1

Hi there,
Im working on Flash frontend for a wordpress blog and have got much further along than I thought I ever would, see WIP here: http://n8w.co.uk/WIP/WordpressFlash/
My next task is to work out how to post comments from flash. I basically have to send some variables to the PHP file shown below.

Obviously the four variables listed a short way down have to be included ie. author, email, url and content.
My php skills are rubbish so am unsure what needs to be included for it to work but it currently isnt.
Im certain there must be an ID required so the PHP knows which post you are commenting on.
And Im quite sure my AS3 script is fine that is sending the variables, as Ive already done it for an earlier part of the project. I have attached the AS3 code also in case there is a problem with that.

If someone who knows some PHP could look over it and shed some light I would really appreciate it.

Big thanks in advance.
