解决问题:form表单提交复选框数据, 只收到最后一条数据

<form action="" method="post">
    <input type="hidden" name="group_id" value="{$group_id}">
    <volist name='pandas' id='panda'>
        <tr>
            <td>{$panda.generation_num}</td>
            <td><input type="checkbox" name="panda_id[]" value="{$panda.id}"></td>
        </tr>
    </volist>
    <tr>
        <td colspan="2" ><button type="submit" style="margin-left: 46%" >提交</button></td>>
    </tr>
</form>

• 用数组作为复选框的name值.
