title: How can I validate in bootstrap that at least one checkbox is marked and pass this information to php?
body: <p>I'm using bootstrap and I created a form with 8 checkboxes. When user clicks "Submit" I want to verify if at least one checkbox is marked and if not - let user know with an error message below the checkbox group.
  Also, I would like to verify if the date that he puts is correct with my default data-form: 23/09/2015 05:45 PM</p>
  
  <p>This is my java-script validation code:</p>
  
  <pre><code>$('#myform').validate({// initialize the plugin
      errorElement: 'div',
      rules: {
          datetimepicker: {
              required: true,
              date: true
          },
          commercialText: {
              required: true,
              minlength: 5
          },
          terms: {
              required: true,
              maxlength: 2
          }
      },
      submitHandler: function (form) { 
          var text = $("#customtext").val();
          var date = $("#datetimepicker").val();
          var stand = 2; 
          $.ajax({
              url: 'savedatanow.php',
              type: "POST",
              data: {
                  text: text,
                  date: date,
                  stand: stand
  
              },
              dataType:'text',
              success: function(response)
              {
  
                  alert(response);
              }
          });
          //alert('outside ajax');
      },
      highlight: function (element) {
          $(element).closest('.form-group').removeClass('success').addClass('has-error');
      },
      success: function (element) {
          element.addClass('valid')
              .closest('.form-group').removeClass('error').addClass('has-success');
      }                   
  });
  </code></pre>
  
  <p>I prepared the following fiddle: <a href="http://jsfiddle.net/5WMff/1316/" rel="nofollow">http://jsfiddle.net/5WMff/1316/</a> but I have a problem with marking the correct error messages in red. When user doesn't check that he accepts the terms there's a weird situation happening too (the whole text is marked in red, not only the error)... Can you help me with that?
  Thanks!</p>
