body: <p>I view the other post but I found nothing, I'm on since 3 days : </p>
  
  <p>I want display 3 'evenements' in the order <code>ASC</code>
  but 2018 is always before 2017</p>
  
  <pre><code>$auj = date('Ymd');
  
  $queryEvent = new WP_Query(
      array(
      'category_name' =&gt; 'evenements',
      'posts_per_page' =&gt; 3,
      'meta_key' =&gt; 'date_de_fin',
      'orberby' =&gt; 'meta_key',
      'order' =&gt; 'ASC',
      'meta_query' =&gt; array(
          array(
              'key' =&gt; 'date_de_fin',
              'value' =&gt; $auj,
              'compare' =&gt; '&gt;=',
          ),
      )
      )
  );
  
  ?&gt;
  </code></pre>
