title: Using Advanced custom fields Repeater field in WooCommerce custom product Tab
body: <p>I am using a Repeater of Advanced custom fields for the content of the my additional custom WooCommerce Tab. The repeater is inside a group field. </p>
  
  <p>I manage to display the custom fields that is outside the repeater field. </p>
  
  <p>Here is the code I used in my <code>functions.php</code>:</p>
  
  <pre><code>add_filter( 'woocommerce_product_tabs', 'dl_custom_product_designer_tab' );
  function dl_custom_product_designer_tab( $tabs ) {
      // ensure ACF is available
      if ( !function_exists( 'have_rows' ) )
          return;
  
      if ( get_field('designer') ) {
          $tabs[] = array(
              'title' =&gt; 'DESIGNER',
              'priority' =&gt; 50,
              'callback' =&gt; 'dl_custom_designer_tab'
          );
      }
      return $tabs;
  }
  
  function dl_custom_designer_tab() {
      $designer = get_field('designer');
          echo '&lt;p&gt;'.$designer['designer_image'].'&lt;/p&gt;';
          echo '&lt;p&gt;'.$designer['designer_name'].'&lt;/p&gt;';
          echo '&lt;p&gt;'.$designer['designer_short_description'].'&lt;/p&gt;';
          // loop through the rows of data
          $achievements = get_field('designer_achievements');
          if( $achievements ) {
              // loop through the rows of data
              echo '&lt;ul&gt;';
              foreach($achievements as $achievement){
                  // display a sub field value
                  echo '&lt;li&gt;'.$achievement['achievement'].'&lt;/li&gt;';
              }
              echo '&lt;/ul&gt;';
          }
  }
  </code></pre>
  
  <p>Now the problem is the field inside my repeater field: The repeater sub field is not displaying anything.</p>
  
  <p>What I am doing wrong? How can I have the output for the repeater sub fields?</p>
