Problem getin mysql results

Hello,

I am new in this forum, and havent read yet the rules, so i apologies if i am breaking one of of them.

I have a database with 3 fields, ID, post_date, post_category,

i am trying since 3 hours to get some results that i want.

So what i am trying to do is:

group the posts by xx category, and order them by date , to get the latest post from that category.

Any help will be really great for me.

Thank you for reading this thread.
