title: Iterate Wordpress custom field?
body: <p>I have a custom field in an Apus theme of type multi checkbox and I need to display the selected values. 
  I am using this code:</p>
  
  <pre><code>  &lt;?php $keywords = get_post_meta( get_the_ID(), REALIA_PROPERTY_PREFIX . 'keywords', true ); ?&gt;
      &lt;?php if ( ! empty( $keywords ) ) : ?&gt;
          &lt;li&gt;&lt;span&gt;&lt;?php echo esc_html__( 'Keywords:', 'apushome' ); ?&gt;&lt;/span&gt; &lt;?php echo esc_attr( $keywords ); ?&gt;&lt;/li&gt;
      &lt;?php endif; ?&gt;
  </code></pre>
  
  <p>What this code is showing is </p>
  
  <pre><code>Keywords: Array
  </code></pre>
  
  <p>How can I loop the field's values to show them on the page?</p>
  
  <p>Best regards
  Americo</p>
