What is the easiest way to create a category filter on the default news/blog template?

[strategicblend 0]

In most cases, a client will want to have the news/blog page only pull from a few specific categories. I'm still not understanding how PP's news/blog template works - what is recommended for the best cat query code and where should it be placed? Thanks!

First enable the base child theme and paste this into platformbase/functions.php. Replace the 1 2 and 3 with your won category id's.

	//Removes certain categories from home page based on category id
	add_action('pagelines_inside_top_theloop' ,'filter_cats');
	function filter_cats(){
		if (is_home()){
			$paged = (get_query_var('paged')) ? get_query_var('paged') : 1; //fixes pagination
			$args = array(
				'cat'=> '-1,-2,-3',
				'paged'=> $paged
			);
			query_posts($args);
		  }
	}

That seems to work, thanks!
