title: Get sticky posts from specific category in WordPress
body: <p>I want to check if a category has sticky posts.
  To do that, I use <code>$sticky = get_option( 'sticky_posts' );</code> on the <code>archive.php</code>.</p>
  
  <p>But it shows all sticky posts from the blog. Not only from the displayed category.
  Is there anything I could add to show only sticky posts from the displayed category or tag?</p>
  
  <p>What I need is a true/false if there are sticky posts. If there are sticky posts I need an array with the IDs.</p>
