Blog sites pingback

[apwade]

I have a discount shopping site Discount Hypermarket: Discount Shopping Portal for the Uk and the world - Free Discount codes, Promotional codes, Discount Vouchers and i have an admin program that when i add discount codes to the site it also writes directly to the database of a blog site so it also displays the discount codes. Since i am writing directly to the database the ping back to inform other blogs of updates does not work (i think it does not work) is it possible via coding to make the ping back work automatically after updating the database.

Any ideas and help i would be very grateful.

Cheers,

Andrew
