将复选框值传递给php - 缺少值

Question

我遇到了一个问题，即我们无法将我们的复选框与其他字段联系起来。

如果我们只检查第二个复选框，它将取第一行选择框的值。

行按日期连接起来，例如2014-06-02，2014-06-03

HTML

 <input type="checkbox" name="date_choice[]" value="2014-06-02">
 <select id="event_start" name="event_start[2014-06-02][]"    onchange="area_choice_click()">
 <option value="">Start Time</option>
 <option value="01:00">1.00AM</option>
 <option value="02:00">2.00AM</option>
 <option value="03:00">3.00AM</option>

 </select>
 <select id="event_end" name="event_end[2014-06-02][]" onchange="area_choice_click()">
 <option value="">End Time</option>
 <option value="01:00">1.00AM</option>
 <option value="02:00">2.00AM</option>
 <option value="03:00">3.00AM</option>
 </select> 



   <input type="checkbox" name="date_choice[]" value="2014-06-03">
 <select id="event_start" name="event_start[2014-06-03][]"        onchange="area_choice_click()">
 <option value="">Start Time</option>
 <option value="01:00">1.00AM</option>
 <option value="02:00">2.00AM</option>
 <option value="03:00">3.00AM</option>
 </select>


 <select id="event_end" name="event_end[2014-06-03][]" onchange="area_choice_click()">
 <option value="">End Time</option>
 <option value="01:00">1.00AM</option>
 <option value="02:00">2.00AM</option>
 <option value="03:00">3.00AM</option>
 </select> 

PHP

  foreach($_POST['date_choice'] as $key=>$team_id){

 $event_date = $_POST['date_choice'][$key]; 

  echo"$event_date";

  $event_start=$_POST['event_start'][$event_date][$key]; 

 }
