PHP GoodsModel::snGenerator示例

$goods = new GoodsModel();
$data = array();
$goods->setField($goods->showField());
//自动格式化数据
$data = $goods->_facade($_POST);
$data['goods_weight'] = $_POST['goods_weight'] * $_POST['weight_unit'];
//自动填充
$data = $goods->_autofill($data);
//自动校验
if (!$goods->_validate($data)) {
    echo $goods->getErr()[0];
    exit;
}
//若没有goods_sn，自动生成
if (!$data['goods_sn']) {
    $data['goods_sn'] = $goods->snGenerator();
}
//上传图片
$updriver = new UploadHelper();
$ori_img = $updriver->doUpload('goods_img');
if ($ori_img) {
    $data['ori_img'] = $ori_img;
    //处理缩略图文件名
    $abs_ori = __ROOT__ . $ori_img;
    $abs_goods = dirname($abs_ori) . "/goods_" . basename($abs_ori);
    $goods_img = str_replace(__ROOT__, '', $abs_goods);
    $abs_thumb = dirname($abs_ori) . "/thumb_" . basename($abs_ori);
    $thumb_img = str_replace(__ROOT__, '', $abs_thumb);
    //将上传图片按一下两种格式resample
    //goods picture 300*400 thumb picture: 160*220
    $data['goods_img'] = $goods_img;
