Offset Specific Category from Main Loop

    My goal is for my main blog page to have a slider of three posts from the Featured category. However, I don’t want to duplicate these posts in the main feed below.

    This is my attempt:

    In my main blog page, I have two separate loops. The first is a custom WP_Query that gets the most recent 3 posts from the Featured Category (I will be turning this into a slider which is irrelevant here). It looks like this…

    <?php
                $args = array(
                  'post_type'     => 'post',
                  'category_name' => 'featured',
                  'orderby'       => 'date',
                  'order'         => 'DESC',
                  'posts_per_page'=> '3',
                  );

              $featured_posts= new WP_Query($args);
              if($featured_posts->have_posts()) : while($featured_posts->have_posts()) :      $featured_posts->the_post(); ?>
              <h2><?php the_title(); ?></h2>
            <?php endwhile; endif; ?>

    Then, I run my normal query to get all the posts. It looks like this…

    <?php if(have_posts()) : while(have_posts()) : the_post(); ?>
      --Do something--
  <?php endwhile; endif; ?>

    Finally, in my functions.php file, I have the following function that hooks into “pre_get_posts” action hook to offset my main query by 3. It looks like this: 

    function wpsites_exclude_latest_post($query) {
if ($query->is_home() && $query->is_main_query()) {
$query->set( 'offset', '3' );
  }
}
add_action('pre_get_posts', 'wpsites_exclude_latest_post');

    Everything is almost working except I want to only offset those posts from the “featured” category so they move from the slider and then down into the main loop and never duplicate. How can I offset the main query by three but only from the featured category? Am I going about this the correct way?

    One way to do this is to save the IDs in the first loop in an array. Then, re-issue the query for the second loop after adding in the ‘post__not_in’ argument with the array of IDs. Assuming you named your array of saved post IDs as $saved_ids, you would re-issue the query like this (untested):

    global $wp_query;
query_posts(
   array_merge(
      $wp_query->query,
      array('post__not_in' => $saved_ids)
   )
);
