title: K2 extra fields access in BT Content slider
body: <p>I'm trying to access the contents of a K2 extra field inside the BT content slider plugin. If I do </p>
  
  <pre><code>print_r($row-&gt;extra_fields);
  </code></pre>
  
  <p>I get </p>
  
  <pre><code>[{"id":"16","value":"http:\/\/www.youblisher.com\/p\/611670-Test-Intro-to-R\/"}]
  </code></pre>
  
  <p>I need to access the value, but I've tried everything I could think of with no luck. </p>
  
  <p>Tests I've done (also tried print_r for everything just in case): </p>
  
  <pre><code>echo $row-&gt;extra_fields[0]
  echo $row-&gt;extra_fields[0]-&gt;value
  echo $row-&gt;extra_fields-&gt;value
  echo $row-&gt;extra_fields["value"]
  </code></pre>
