Vbulletin custom payment urls for each thread

[nam6641]

Can anyone help, i need help urgently..
i need to make payment subscription for each thread for my vbulletin 3 powered forum,
Basically, i want to make a subscription for each thread that posted(moderation enabled), i want to get the payments urls like this
www.myforum.com/payments.php?do=order&t=threadid
so as you can see in the above url, i want to make payments urls like this for each thread, and i want another function when a user pays through that url its thread will be automatically approved(moderation enable on the category in which thread is posted).

ANy one can help please,,,,,,,,
