WordPress Get the Excerpt Outside the Loop

Unfortunately, you cannot use get_the_excerpt outside "the loop". This is a similar function that can be used anywhere in your theme or template.

This snippet can even be used to display the excerpt for any post anywhere on any page. Just pass in the post ID of the post to show the excerpt for.

function get_the_excerpt_here($post_id)
{
  global $wpdb;
  $query = "SELECT post_excerpt FROM $wpdb->posts WHERE ID = $post_id LIMIT 1";
  $result = $wpdb->get_results($query, ARRAY_A);
  return $result[0]['post_excerpt'];
}
