复选框不工作

我有一个HTML表单，张贴到一个PHP脚本。除复选框外，一切正常。当它被选中时，值没有被发送。

<input name="test" id="checkbox-02" type="checkbox" value="1" />

if(!isset($_POST['test'])) {
  $eventRepeat="No";
}
if(isset($_POST['test'])) {
  $eventRepeat="Yes";
}

当这段代码运行时，$eventRepeat总是显示为"No"。我尝试使用命令"print_r($_POST)"，所有输入都被张贴，除了复选框，，即使它被选中。

你知道是什么原因导致的吗?我确实有jQuery运行，所以当它被选中两个div出现。会不会是某种干扰?这是jQuery:

$(document).ready(function () {
$('#checkbox-02').change(function () {
    if (!this.checked) 
    //  ^
       $('#repeatUntilDIV').fadeIn('slow');
       $('#repeatFrequencyDIV').fadeIn('slow');
});
});

作为参考，这里是完整的代码:

           <form class="cmxform form-horizontal tasi-form" id="commentForm" role="form" action="" method="post">
        <div class="form-group">
            <label for="inputEventTitle" class="col-lg-2 control-label">Event Title</label>
            <div class="col-lg-10">
                <input type="text" class="form-control" id="inputEventTitle" name="inputEventTitle" placeholder="Event Title" required>
            </div>
        </div>
        <div class="form-group">

        </div>
        <div class="form-group">

              </select>
          </div>
        </div>  
        <div class="form-group">
            <label for="inputEventEndTime" class="col-lg-2 control-label">End Time</label>
            <div class="col-lg-10">

              </select>                </div>
        </div>                      
        <div class="form-group">
          <label class="control-label col-sm-2">Date</label>
          <div class="col-sm-6">

         <div class="form-group">

              <input name="test" id="checkbox-02" type="checkbox" value="1" /> Yes, I want to repeat this event.
            </div>
        </div>
         <div class="form-group" id="repeatUntilDIV" style="display:none;">
            <label for="inputEventEndDate" class="col-lg-2 control-label">Repeat Until</label>
            <div class="col-lg-10">

         <div class="form-group" id="repeatFrequencyDIV" style="display:none;">
            <label for="inputEventFrequency" class="col-lg-2 control-label">Repeat Every</label>
            <div class="col-lg-10">
             <select name="inputEventFrequency" class="form-control" id="dp1">
                <option label="Repeat Every">
                <option value="1">Repeat Every Day</option>
                <option value="2">Repeat Every Other Day</option>
                <option value="7">Repeat Every Week</option>
                <option value="14">Repeat Every Other Week</option>
                <option value="30">Repeat Every Month</option>
              </select>
            </div>
        </div>                          
  </div>
  <div class="modal-footer">
    <button type="button" class="btn btn-primary" data-dismiss="modal">Cancel</button>
    <input type="submit" name="addPrimaryEvent" class="btn btn-success" value="Submit" />
       </form>

我得到这个从var_dump($_POST):

  array(8) {
  ["inputEventTitle"]=>
  string(5) "Title"
  ["inputEventDescription"]=>
  string(11) "Description"
  ["inputEventStartTime"]=>
  string(6) "2:00AM"
  ["inputEventEndTime"]=>
  string(6) "3:00AM"
  ["inputEventDate"]=>
  string(10) "05-26-2014"
  ["inputEventEndDate"]=>
  string(10) "05-29-2014"
  ["inputEventFrequency"]=>
  string(1) "1"
  ["addPrimaryEvent"]=>
  string(6) "Submit"
}
