Yii框架CMultifileupload不工作

我正在尝试使用CMultiFileUpload和cuploaddedfile实现多文件上传，但它不起作用。具体来说，_POST即使考虑到我在视图的选项中使用了'enctype'=>'multipart/form data'，也不起作用：

<?php $form=$this->beginWidget('CActiveForm', array(
    'id'=>'examen-form',
    'enableAjaxValidation'=>false,
    'htmlOptions' => array('enctype' => 'multipart/form-data'),

---

我认为问题出在post方法中，因为控制器没有上传文件，也没有对数据库进行任何更改。但我不确定。

尝试更改为

'htmlOptions'=>array（'multiple'=>true）

在表单中添加以下代码

'htmlOptions' => array(
            'enctype' => 'multipart/form-data',
        ),

像

我使用的是同一个扩展名，它为我提供了这些代码 在视图文件中

<?php $form = $this->beginWidget('CActiveForm', array(
'id'=>'adpost-form',
'enableClientValidation'=>true,
'clientOptions' => array(
     'validateOnSubmit'=>true,
     'validateOnChange'=>false,
     'afterValidate'=>'js:submiAjaxForm'
 ),
'htmlOptions' => array('enctype' => 'multipart/form-data'),

array('archivo_foto','file','allowEmpty'=>true,'maxFiles'=>10),

'htmlOptions' => array(
            'enctype' => 'multipart/form-data',
        ),

<?php $form=$this->beginWidget('CActiveForm', array(
    'id'=>'form',
    // Please note: When you enable ajax validation, make sure the corresponding
    // controller action is handling ajax validation correctly.
    // There is a call to performAjaxValidation() commented in generated controller code.
    // See class documentation of CActiveForm for details on this.
    'enableAjaxValidation'=>true,

     'htmlOptions' => array(
        'enctype' => 'multipart/form-data',
    ),
)); ?>

<?php $form = $this->beginWidget('CActiveForm', array(
