title: ACF if have_rows( ) not returning anything
body: <p>I'm trying to use a repeater field and can't seem to get it to work. I think it's an issue with my if statement because if I remove the while loop and try echo out anything from <code>&lt;?php if( have_rows($aboutInfo['cards']): ?&gt;</code> I get nothing. I've tried without the ID, and a hardcoded ID as the 2nd param. Also, just to test I did <code>&lt;?php if( !have_rows($aboutInfo['cards']): ?&gt;</code> and was able to get something to echo out.</p>
  <p>The print_r above the if statement displays the array.</p>
  <pre><code>&lt;?
   /*
   Template Name: 01-Homepage
   */
   get_header(); ?&gt;
   &lt;? $aboutInfo = get_field( 'about' ) ?&gt;
   &lt;?$postid = get_the_ID(); ?&gt;
   &lt;div class=&quot;row&quot;&gt;
     &lt;div class=&quot;columns small-12 medium-7&quot;&gt;
       &lt;h2&gt;
         &lt;?= $aboutInfo['title'] ?&gt;
       &lt;/h2&gt;
       &lt;p class=&quot;lead&quot;&gt; &lt;?= $aboutInfo['content'] ?&gt;&lt;/p&gt;
       &lt;pre&gt;&lt;?php print_r($aboutInfo['cards']) ?&gt;&lt;/pre&gt;
       &lt;?php if( have_rows($aboutInfo['cards'], $postid) ): ?&gt;
         &lt;?php while(have_rows($aboutInfo['cards'])) : the_row(); ?&gt;
         &lt;?php $image = get_sub_field('image') ?&gt;
         &lt;p&gt;&lt;?= $image['url'] ?&gt;&lt;/p&gt;
         &lt;?php endwhile; ?&gt;
       &lt;?php endif; ?&gt;
     &lt;/div&gt;
   &lt;/div&gt;
   &lt;?php get_footer(); ?&gt;
  </code></pre>
  <p>Here is what my ACF looks like
