How set featured posts using checkbox in post edit screen?

1. You can do this by following these steps:

   1. Add a custom meta box to your posts
   2. Create a function to save the meta data using the save_post action
   3. Add the ‘meta_key’ query argument to whatever query you are using.

   Place this in your themes functions.php file:

   function register_post_assets(){
       add_meta_box('featured-post', __('Featured Post'), 'add_featured_meta_box', 'post', 'advanced', 'high');
   }
   add_action('admin_init', 'register_post_assets', 1);
   
   function add_featured_meta_box($post){
       $featured = get_post_meta($post->ID, '_featured-post', true);
       echo "<label for='_featured-post'>".__('Feature this post?', 'foobar')."</label>";
       echo "<input type='checkbox' name='_featured-post' id='featured-post' value='1' ".checked(1, $featured)." />";
   }
   
   function save_featured_meta($post_id){
       // Do validation here for post_type, nonces, autosave, etc...
       if (isset($_REQUEST['_featured-post']))
           update_post_meta(esc_attr($post_id, '_featured-post', esc_attr($_REQUEST['_featured-post']))); 
           // I like using _ before my custom fields, so they are only editable within my form rather than the normal custom fields UI
   }
   add_action('save_post', 'save_featured_meta');
   

   Then in your template file use the following for the main loop:

       $args = array(
           'meta_key' => '_featured-post', // include underscore prefix in key name
           'meta_value' => 1
       );
       // The number of posts displayed would be determined under Settings->Reading
       query_posts($args);
   
       if(have_posts()): while(have_posts()): the_post();
           // Do your bidding here
   
       endwhile; else:
   
       endif;
   

   FOR EXAMPLE PURPOSES ONLY: For custom loops (If running multiple loops on one page), you would use this:

       $args = array(
           'posts_per_page' => 5,
           'meta_key' => '_featured-post',
           'meta_value' => 1
       );
   
       $featured = new WP_Query($args);
   
       if ($featured->have_posts()): while($featured->have_posts()): $featured->the_post();
           the_title();
           the_content();
       endwhile; else:
   
       endif;

2. I tried to run this code and it helps me a lot for displaying my featured post on my homepage for my case study custom post type. Thanks a lot.

            <?php $args = array( 
                   'post_type' => 'case_studies',
                   'posts_per_page' => 1,
                   'meta_key' => 'featured_post',
                   'meta_value' => 1
               );
   
               $featured = new WP_Query($args);
   
               if ($featured->have_posts()): while($featured->have_posts()): $featured->the_post(); ?>
                   <div class="c-image"><?php the_post_thumbnail('large'); ?></div>
                   <div class="cstext">
                        <article>
                           <h2><?php the_title(); ?></h2>  
                           <span class="sub-title"> USAF SOCONS </span>
                           <?php the_content(); ?>
                           <a href="<?php echo get_permalink(); ?>" class="readmore">Learn More</a>
                       </article> 
   
                       <a href="/case-studies" class="btn-primary">View all Case Studies</a>
   
                   </div> 
   
               <?php 
                   endwhile; 
                       else: 'No Content Added';
               endif; ?>
       </div>
   </div>
