controller：

仅调用create、add方法：

$goods = new GoodsModel();
                $goods->create();
                if ($goods->add()) {
                    $this->redirect("showlist");
                } else {
                    $this->redirect('add');
                }

model：

在\_before\_insert中实现功能：

protected function _before_insert(&$data, $options) {
            parent::_before_insert($data, $options);
    
            // COMMENT: Logo上传处理 **** START ****************/
            if ($_POST['general_act'] === 'general_tab') {
                if ($_FILES['f_goods_image']['error'] === 0) {
                    $up = new Upload(array('rootPath' => './Common/Uploads/'));
                    $z  = $up->uploadOne($_FILES['f_goods_image']);
                    if ($z) {
                        $data['goods_big_logo']   = $up->rootPath . $z['savepath'] . $z['savename'];
                        $data['goods_small_logo'] = $up->rootPath . $z['savepath'] . "small_" . $z['savename'];
    
                        // 制作缩略图
                        $im = new Image();
                        $im->open($data['goods_big_logo']);
                        $im->thumb(60, 60);
                        $im->save($data['goods_small_logo']);
                    }
                }
            }
            // COMMENT: Logo上传处理 ***** END *****************/
        }

HTML：

<tr>
                    <th>商品图片</th>
                    <td><input type="file" name="f_goods_image" id="f_goods_image"/>
                        <div id="f_goods_image_div">
                            <img src="" alt="" id="f_goods_image_img" height="100">
                        </div>
                    </td>
                </tr>
                <script type="text/javascript">
                    $(function () {
                        new uploadPreview({
                            UpBtn: "f_goods_image",
                            DivShow: "f_goods_image_div",
                            ImgShow: "f_goods_image_img"
                        })
                    })
                </script>
