title: JQuery validate with multiple custome methods
body: <p>I'm trying to create a validation for a couple elements. The miminum test I'm trying is something like this:</p>
  
  <p><div class="snippet" data-lang="js" data-hide="false" data-console="true" data-babel="false">
  <div class="snippet-code">
  <pre class="snippet-code-html lang-html prettyprint-override"><code>&lt;html&gt;
  &lt;head&gt;
   &lt;script src="https://code.jquery.com/jquery-3.2.1.min.js"&gt;&lt;/script&gt;
   &lt;script src="http://cdnjs.cloudflare.com/ajax/libs/jquery-validate/1.16.0/jquery.validate.min.js" type="text/javascript"&gt;&lt;/script&gt;
  &lt;/head&gt;
  &lt;body&gt;
  
  &lt;form&gt;
  &lt;input id="valCategories" class="valCategories" type="hidden" value="0" /&gt;
  &lt;input id="valPermissions" class="valPermissions" type="hidden" value="0" /&gt;
  
  &lt;input type="submit" value="submit"/&gt;
  &lt;/form&gt;
  
  &lt;script&gt;
  $(document).ready(function(){
  
   // jQuery Validate Settings
   $.validator.setDefaults({
    ignore: ''
   });
   $.validator.addClassRules({});
   
   $.validator.addMethod('valPermissions', function (value, element) {
       return !!+value;
   },"error permissions");
   $.validator.addMethod('valCategories', function (value, element) {
       return !!+value;
   },"error categories");
  
   $('form').validate();
  });
  &lt;/script&gt;
  
  &lt;/body&gt;
  &lt;/html&gt;</code></pre>
  </div>
  </div>
  </p>
  
  <p>I'm expecting to get two error messages:
  - error permissions
  - error categories
  but no matter what I try I only get a single error message.</p>
  
  <p>What am I missing here?</p>
