combobox with multiple and multiline in form , when submit form, the combobox commit each select value with same variable name to server.


thml example:

   ^{<div class="easyui-panel" title="New Topic" style="width: 400px">
      <div style="padding: 10px 60px 20px 60px">
         <form id="ff" method="post" action="action.php">
            <select class="easyui-combobox" name="state"
               data-options="multiple:true,multiline:true"
               style="width: 200px; height: 50px">
               <option value="AL">Alabama</option>
               <option value="AK">Alaska</option>
               <option value="AZ">Arizona</option>
               <option value="AR">Arkansas</option>
               <option value="CA">California</option>
               <option value="CO">Colorado</option>
               <option value="CT">Connecticut</option>
               <option value="DE">Delaware</option>
               <option value="FL">Florida</option>
               <option value="GA">Georgia</option>
               <option value="HI">Hawaii</option>
               <option value="ID">Idaho</option>
            </select>
         </form>
         <div style="text-align: center; padding: 5px">
            <a href="javascript:void(0)" class="easyui-linkbutton"
               onclick="submitForm()">Submit</a> <a href="javascript:void(0)"
               class="easyui-linkbutton" onclick="clearForm()">Clear</a>
         </div>
      </div>
   </div>
   <script>
      function submitForm() {
         $('#ff').form('submit');
      }
      function clearForm() {
         $('#ff').form('clear');
      }
   </script>}

select 'Alabama' and 'Alaska'  in this form , and then submit form , use firebug to catch the post params , we found it post two parameter value 'AL' and 'AK' with same variable name 'state', not submit one parameter 'state' .

in firebug the form data like this:
state:'AL'
state:'AK'

normal the form must post parameter name 'state' and with value 'AL,AK', but in this case, the server side 'action.php' will only receive the last 'state' value of 'AK' , and the value 'AL' was lost.

how to resolve it?

It is not the bug. Please use the 'state[]' name instead in your page code.

yes use  name='state[]'  it's work fine, think you very much.
