One problem many people have is excluding a specific category from their home page. Here is a function that does just that.


function exclude_category($query){
$your_category_id = 'the category_id to exclude
if($query->is_home)
{
$query->set('cat','-'.$your_category_id .'');
}
return $query;
}


Now to get it to work call a WordPress add_filter


add_filter('pre_get_posts','exclude_category');


and complete the function like this:


function exclude_category($query){
$your_category_id = 'the category_id to exclude
if($query->is_home)
{
$query->set('cat','-'.$your_category_id.'');
}
return $query;
}
add_filter('pre_get_posts','exclude_category');


Place the function in your relevant functions page and hey-presto $your_category_id will not appear on the home page.

Another varient to

if($query->is_home)


is


if($query->is_feed)


This applies if the page is a feed page and you have say a static home page
