title: WordPress: WP_Query with page_id AND meta_query
body: <p>I have a problem with WP_Query:</p>
  
  <p>I need get a list of a custom post types with a custom meta key <code>scuola_data_approved=1  OR post_id=1208</code></p>
  
  <p>I have tried to manipulate the following query but I can not find a working solution:</p>
  
  <pre><code>$args = array
  (
  'post_type'  =&gt; 'scuole', 
  'posts_per_page' =&gt; -1,
  'relation' =&gt; 'OR',
  'page_id'=&gt;1208,
  'meta_query' =&gt; array
  ( 
      'relation' =&gt; 'OR',
      array(
         'key'     =&gt; 'scuola_data_approved',
         'value'   =&gt; '1',
         'compare' =&gt; '='
      ),
  
  ),
  
  );
  </code></pre>
