PHP上传图片OSS同步更新

php的   图片缩略  只有在上传完成之后才能进行缩略吗  

写得很乱

欢迎进行技术分享，感谢你的支持！

但是小白的我看不懂，希望出一整套源码代码 以多文件形式传上来

下面附上我的代码，PHP用的是Thinkphp3.2的框架
public function add(){
        if(IS_POST){
            $oss_sdk_service = new \ALIOSS();
            //设置是否打开curl调试模式
            $oss_sdk_service->set_debug_mode(true);
            $news_mod = D('News');
            $data ['title'] =  I('post.title','','htmlspecialchars');
            $data['ord'] = 0;
            $data['addtime'] = time();
            $data['status'] = 0;
            if (isset($_FILES['pic'])){
                //文件上传配置,可以生成缩略图
                $date11 =date('Ymd');
                $upload = new \Think\UploadFile();// 实例化上传类
                $upload->maxSize  = 80000000 ;// 设置附件上传大小
                $upload->allowExts  = array('jpg', 'gif', 'png', 'jpeg');// 设置附件上传类型
                $upload->allowTypes = array('image/jpg','image/jpeg','image/pjpeg','image/png','image/gif');
                $upload->savePath =  './Upload/news/'.$date11.'/';// 设置附件上传目录
                $upload->saveRule = 'uniqid';
                //缩略图配置
                $upload->thumb = true;
                $upload->thumbMaxWidth = '300';
                $upload->thumbMaxHeight = '380';
                $upload->thumbPrefix = '';
                $upload->thumbSuffix ='.300';
                $upload->thumbRemoveOrigin = false;
                //开始上传
                if($upload->upload()){
                    $info =  $upload->getUploadFileInfo();
                    //大图
                    $data['picurl'] =  '/Upload/news/'.$date11.'/'.$info[0]['savename'];
                    //上传到OSS
                    $picurl ='./Upload/news/'.$date11.'/'.$info[0]['savename'];
                    //缩略图
                    $thumbpic = getThumb($picurl,6);
                    $thumbfilename = end ( explode ( '/', $thumbpic ) );;
                    upload_by_file($oss_sdk_service,'Upload/news/'.$date11.'/'.$info[0]['savename'], $picurl);
                    upload_by_file($oss_sdk_service,'Upload/news/'.$date11.'/'.$thumbfilename, $thumbpic);
                }
            }
            $result = $news_mod->add($data);
            if(false !== $result){
                $this->success ( '新增成功！',  U('Home/Index/add') );
            }
            else{
                $this->error ( '新增巡失败！' );
            }
        }else{
            $this->display();
        }
    }

html代码
<form action="" method="post" enctype="multipart/form-data" name="form1">
  <table width="600" border="0" align="center" cellpadding="0" cellspacing="0">
    <tr>
      <td height="30" colspan="2" align="center">上传图片</td>
    </tr>
    <tr>
      <td width="140" height="30" align="right">标题：</td>
      <td width="460" height="30"><input type="text" name="title"></td>
    </tr>
    <tr>
      <td height="30" align="right">上传图片：</td>
      <td height="30"><input type="file" name="pic"></td>
    </tr>
    <tr>
      <td height="30" align="right"> </td>
      <td height="30"><input type="submit" name="Submit" value="提交"></td>
    </tr>
  </table>
</form>

//获取图片的缩略图名称

function getThumb($image,$lx) {
    $filename = end ( explode ( '/', $image ) );
    $filename1=explode('.',$filename);
    if ($filename1) {
        if($lx==1){
            $lxtt = '.120.';
        }else if($lx==2){
            $lxtt = '.150.';
        }else if($lx==3){
            $lxtt = '.180.';
        }else if($lx==4){
            $lxtt = '.200.';
        }else if($lx==5){
            $lxtt = '.280.';
        }else if($lx==6){
            $lxtt = '.300.';
        }
        $files = $filename1[0].$lxtt.$filename1[1];
        $newfile=str_replace($filename,$files,$image);
        return $newfile;
    }
}

希望这个帖子能加金啊

加个函数upload_by_file()
//通过路径上传文件
function upload_by_file($obj,$object,$file_path){
    $bucket = 'dengwei1999';
   // $object = '115001_1313.jpg';
   // $file_path = "../pic/115001_1313.jpg";
    $response = $obj->upload_file_by_file($bucket,$object,$file_path);
   // _format($response);
}
