Using loop functions to call specific data

    I’m using word press to control the news feed on my website. I have had no problem creating my own template, which works great as the news homepage of the website.

    However, I want to have posts from specific categories show up on the main home of my website (outside of the news section). For example I have about 7 categories but I want only the latest post from categories 3 and 4 to show up on the homepage of my website.

    I started out writing my own code to query the information from the word press database but I would much rather use word press functions.

    Is there some function I can call that will only get the latest post from a specific category?

    Thanks,
    David

wp_reset_query();  // Restore global post data stomped by the_post().

    This works great although rather than showing 3 posts from each category it shows all of them.

    Also is there a way to show posts that are in one category but not in another.

    Example: post 1 belongs to category 3, 4, & 7, and post 2 belongs to category 3,4. So I only want show posts from category 3 and not 7. So the output would only show post 2.

    I figured out a way to do it… I’ll post my code in a bit for anyone else who might read.

    'posts_per_page' => -1,

    that should be

    'posts_per_page' => 3,
