I've tried looking at the database but I can't seem to be able to make a query to do this. How can I look up posts from only one category, or more specifically, I just need the ID of the last post from the category.
I'm trying to do this in index.php
Using get_posts
will do what you need, documentation here
something along the lines of the following
<?php
$postsincat = get_posts(array("cat" => 1, "showposts" => 1));
$idoflatestpostincategory = $postsincat[0]->ID;
?>
You could also use category_name
instead of cat
in the array to use a name instead of ID.
