视图表单代码如下：

<tr id="research-items">
	<td>
        <select name="type[]">
            <option value="text">单行文字</option>
            <option value="textarea">多行文字</option>
            <option value="radio">单项选择</option>
            <option value="checkbox">多项选择</option>
        </select>
	</td>
	<td><input type="text" name="question[]" value="" placeholder="这里是问题"></td>
	<td><input type="text" name="items[]" value="" placeholder="答案1|答案2"></td>
	<td>
        <input type="checkbox" name="is_answer[]" value="1" <?php echo (isset($data) && $data['ResearchSetting']['is_answer']==1) ? "checked" : '' ; ?>>是否必填
	</td>
	<td><a class="btn_delete" title="删除" href="javascript:;">删除</a></td>
</tr>

控制器的写法如下：

for ($i=0; $i < count($_POST['type']) ; $i++) {
     $post[$i]['ResearchOption']['type']                = $_POST['type'][$i];
     $post[$i]['ResearchOption']['question']            = $_POST['question'][$i];
     $post[$i]['ResearchOption']['items']               = $_POST['items'][$i];
     $post[$i]['ResearchOption']['is_answer']           = ($_POST['is_answer'][$i])?$_POST['is_answer'][$i]:0;
     $post[$i]['ResearchOption']['research_setting_id'] = $this->ResearchSetting->id;
}
$this->ResearchOption->saveAll($post);
