title: req.body empty for textarea in http form (Using Express)
body: <p>I have the following form to have the user upload a file and submit text:</p>
  
  <pre><code>form(action='/createpost' enctype="multipart/form-data" method='post' id="imgForm")
      input(type='file' name='imgPath' size = "60")
      br
      textarea(name="postText" form="imgForm") Enter your post text here...
      br
      input(type='submit' value="Submit")
  </code></pre>
  
  <p>When I run this:</p>
  
  <pre><code>router.post('/createpost', function(req,res){
    console.log("POST FORM BODY", req.body.postText);
    res.end();
  });
  </code></pre>
  
  <p>I get <code>undefined</code> in the console. How do I get the value of the input inside textarea? </p>
