Reply To: Query posts by value (array?) and not by fieldname

One step further…. this works for the first loop:

<?php 
   $posts = get_posts(array('meta_key'	=> 'Content'));
   if( $posts ) {
      $anzContent = array();
      foreach( $posts as $post ) {
         setup_postdata( $post );
         $anzContent[] = get_field('Content'); 
      }; //foreach( $posts as $post )
      $uniqueContent = array_unique($anzContent);			
      foreach( $uniqueContent as $contentboxes ) {
         setup_postdata( $contentboxes );
         echo('<div class="Contentbox">');
         echo($contentboxes);
         echo('</div>'); //Contentbox
      } //foreach( $uniqueContent as $contentboxes )
   }; //if( $posts )
   wp_reset_query();
?>

To get the Contentboxes i did 2 loops. One loop to get all Content values of all posts (like A,A,B,E,D,D,D).
then I put this array in an array_unique to get each value only once (A,B,E,D)
For each of this array_unique_values i createt a <div>.
This works so far.

Now i tried to get the wraps of each Contentbox the same way:

<?php 
   $posts = get_posts(array('meta_key'	=> 'Content'));
   if( $posts ) {
      $anzContent = array();
      foreach( $posts as $post ) {
         setup_postdata( $post );
         $anzContent[] = get_field('Content'); 
      }; //foreach( $posts as $post )
      $uniqueContent = array_unique($anzContent);			
      foreach( $uniqueContent as $contentboxes ) {
         setup_postdata( $contentboxes );
         echo('<div class="Contentbox">');

            $wraps = get_posts(array('meta_value' => $contentboxes));
            if( $wraps ) {
               $anzwraps = array();
               foreach( $wraps as $wrap ) {
                  setup_postdata( $wrap );
                  $anzwraps[] = get_field('wrap'); 
               }; //foreach( $wraps as $wrap )
               $uniquewrap = array_unique($anzwraps);			
               foreach( $uniquewrap as $thiswrap ) {
                  setup_postdata( $thiswrap );
                  echo('<div>');
                  echo($thiswrap);
                  echo('</div>');
                };
             };		

         echo('</div>');
      };
   };
   wp_reset_query();
?>

This is not working. It echoes the same value each contentbox. Why? I don’t get it… 🙁
