在cakephp中一次提交中插入多行

在这件事上我真的需要帮助。我想允许用户以单眉多上传

视图如下所示：

<?php echo $this->Form->create('TypologyPicture', array('type'=>'file')); ?>
        <legend><?php echo __('Add Picture'); ?></legend>
    <?php
        echo $this->Form->input('id');
        echo $this->Form->input('typology_id');
        echo $this->Form->input('pic_path', array('label'=>'Picture','type'=>'file','multiple'=>'multiple'));

    ?>
<?php echo $this->Form->end(__('Submit')); ?>
</div>

/**
 * add method
 *
 * @return void
 */
    public function add() {
        if ($this->request->is('post')) {
            $this->TypologyPicture->create();
            if ($this->TypologyPicture->save($this->request->data)) {
                $this->Session->setFlash(__('The typology picture has been saved.'));
                return $this->redirect(array('action' => 'index'));
            } else {
                $this->Session->setFlash(__('The typology picture could not be saved. Please, try again.'));
            }
        }
        if ( AuthComponent::user('role')==='admin' ||AuthComponent::user('role')==='superadmin' ){
            $typologies = $this->TypologyPicture->ItemTypologyPicture->find('list');
        } else {
            $typologies = $this->TypologyPicture->ItemTypologyPicture->find('list', array('conditions' => array('ItemTypologyPicture.user_id' => AuthComponent::user('id'))));
            }
        $this->set(compact('typologies'));
    }

所以我想实现的是，当用户点击浏览时，他可以选择多张图片，也可以选择这张图片所属的类型。因此，当他点击提交所有选择的phottos上传，并属于他刚才选择的类型。那么，如何只需一次提交就可以将所有图像路径保存在db中

这在CakePHP书中关于的章节中有非常清楚的解释，特别是关于Thanx的部分，我将看一看
