1上传多张图片, 要对 $_FILES进行 重新处理.

     //添加

     public function addCourseAlbumAction()

     {

         $CourseAlbumModel = new CourseAlbumModel();

         $CourseAlbumModel->title = $_REQUEST["title"];

         $CourseAlbumModel->courseId = $_REQUEST["courseId"];

         if(!empty($_FILES))

         {

             $tempArr = $_FILES["url"];

             $imageArr = array();

             foreach ($tempArr as $k => $v)

             {

                 foreach ($v as $k2 => $v2)

                 {

                     $imageArr[$k2][$k] = $v2;

                 }

             }

             foreach ($imageArr as $k => $v)

             {

                 $upload = new BaseUploadUtil();

                 $upload->createPath();

                 $upload->createDatePath();

                 $upload->file = $v;

                 $info = $upload->upload();

                 if(count($info)>0){

                     $CourseAlbumModel->url = $info["path"];

                 }

                 $CourseAlbumModel->orderBy = $_REQUEST["orderBy"];

                 $CourseAlbumModel->lastUpdateTime = time();

                 $CourseAlbumModel->insert();

             }

             echo 1;

         }

         else

         {

             $CourseAlbumModel->orderBy = $_REQUEST["orderBy"];

             $CourseAlbumModel->lastUpdateTime = time();

             echo $CourseAlbumModel->insert();

         }

     }

关键代码:

             $tempArr = $_FILES["url"];

             $imageArr = array();

             foreach ($tempArr as $k => $v)

             {

                 foreach ($v as $k2 => $v2)

                 {

                     $imageArr[$k2][$k] = $v2;

                 }

             }

             foreach ($imageArr as $k => $v)

             {

                 $upload = new BaseUploadUtil();

                 $upload->createPath();

                 $upload->createDatePath();

                 $upload->file = $v;

                 $info = $upload->upload();

             }

处理后的 数组是  $imageArr.   之后 每次上传 就是  $upload->file = $v;

2fileinput 上传多张图片.

            // echo BaseView::getImageHtml(array("name"=> "original","label"=> $_courseAlbum->getFieldDesc("original")));

            // echo BaseView::getHrHtml();

            echo '<fieldset>

                    <div class="form-group">

                         <label class="col-sm-2 control-label">' . $_courseAlbum->getFieldDesc("original") . ':</label>

                         <div class="col-sm-9">

                             <input id="original_0" name="original[]" type="file" class="file" multiple="true" />

                         </div>

                         <script type="text/javascript">

                         $("#original_0").fileinput({

                             language: "zh",

                             showUpload:false,

                              browseLabel:"<span style=\'color:#fff;\'>选择'. $_courseAlbum->getFieldDesc("original").'</span>",

                             showClose:false,

                             maxFileCount: 10

                         });

                         </script>

                    </div>

                </fieldset>';

            echo BaseView::getHrHtml();

1. name="original[]"   这是一个数组.

2.multiple="true"  允许多选.

3. maxFileCount: 10 最大允许10个文件.

php端代码:

    //添加 ---> 上传多张:

    public function addCourseAlbumAction()

    {

        $CourseAlbumModel = new CourseAlbumModel();

        $CourseAlbumModel->title = $_REQUEST["title"];

        $CourseAlbumModel->courseId = $_REQUEST["courseId"];

        // if(!empty($_FILES)){

        //     $upload = new BaseUploadUtil();

        //     $upload->createPath();

        //     $upload->createDatePath();

        //     $upload->file = $_FILES["original"];

        //     $info = $upload->upload();

        //     if(count($info)>0){

        //         $CourseAlbumModel->original = $info["path"];

        //     }

        // }

        // $CourseAlbumModel->orderBy = $_REQUEST["orderBy"];

        // $CourseAlbumModel->lastUpdateTime = time();

        // echo $CourseAlbumModel->insert();

        if(!empty($_FILES))

        {

            $tempArr = $_FILES["original"];

            $imageArr = array();

            foreach ($tempArr as $k => $v)

            {

                foreach ($v as $k2 => $v2)

                {

                    $imageArr[$k2][$k] = $v2;

                }

            }

            foreach ($imageArr as $k => $v)

            {

                $upload = new BaseUploadUtil();

                $upload->createPath();

                $upload->createDatePath();

                $upload->file = $v;

                $info = $upload->upload();

                if(count($info)>0){

                    $CourseAlbumModel->original = $info["path"];

                }

                $CourseAlbumModel->orderBy = $_REQUEST["orderBy"];

                $CourseAlbumModel->lastUpdateTime = time();

                $CourseAlbumModel->insert();

            }

            echo 1;

        }

        else

        {

            $CourseAlbumModel->orderBy = $_REQUEST["orderBy"];

            $CourseAlbumModel->lastUpdateTime = time();

            echo $CourseAlbumModel->insert();

        }

    }

3修改,删除的时候删除原来的资源,图片 update, delete

     //修改

     public function updateCourseAction()

     {

         $CourseModel = new CourseModel($_REQUEST["id"]);

         $CourseModel->title = $_REQUEST["title"];

         $CourseModel->userId = $_REQUEST["userId"];

         if(!empty($_FILES['defaultImg'])){

             $upload = new BaseUploadUtil();

             $upload->createPath();

             $upload->createDatePath();

             $upload->file = $_FILES["defaultImg"];

             $info = $upload->upload();

             //删除:

             $this->deleteService($CourseModel->defaultImg);

             if(count($info)>0){

                 $CourseModel->defaultImg = $info["path"];

             }

         }

         if(!empty($_FILES['icon'])){

             $upload = new BaseUploadUtil();

             $upload->createPath();

             $upload->createDatePath();

             $upload->file = $_FILES["icon"];

             $info = $upload->upload();

             //删除:

             $this->deleteService($CourseModel->icon);

             if(count($info)>0){

                 $CourseModel->icon = $info["path"];

             }

         }

         $CourseModel->remark = isset($_REQUEST["remark"]) ? $_REQUEST["remark"] : "";

         $CourseModel->orderBy = $_REQUEST["orderBy"];

         $CourseModel->numb = $_REQUEST["numb"];

         $CourseModel->theKey = $_REQUEST["theKey"];

         $CourseModel->isOpen = $_REQUEST["isOpen"];

         $CourseModel->lastUpdateTime = time();

         echo $CourseModel->update();

     }

     //删除

     public function deleteCourseAction()

     {

         $ids = $_REQUEST["ids"];

         for($i=0;$i<count($ids);$i++)

         {

             $CourseModel = new CourseModel($ids[$i]);

             if(!$CourseModel->delete())

             {

                 echo false;

                 return;

             }

             //删除:

             $this->deleteService($CourseModel->defaultImg);

             $this->deleteService($CourseModel->icon);

         }

         echo true;

     }

     //物理删除:

     public function deleteService($address)

     {

         $file = UPLOAD_PATH . $address;

         if (is_file($file)) {

             # code...

             unlink($file);

         }

     }

4生成器中两个字段上传图片的时候,要修改.

下面是生成器生成的:

     //添加

     public function addCourseAction(){

         $CourseModel = new CourseModel();

         $CourseModel->title = $_REQUEST["title"];

         $CourseModel->userId = $_REQUEST["userId"];

 6         if(!empty($_FILES)){

             $upload = new BaseUploadUtil();

             $upload->createPath();

             $upload->createDatePath();

             $upload->file = $_FILES["defaultImg"];

             $info = $upload->upload();

             if(count($info)>0){

                 $CourseModel->defaultImg = $info["path"];

             }

         }

16         if(!empty($_FILES)){

             $upload = new BaseUploadUtil();

             $upload->createPath();

             $upload->createDatePath();

             $upload->file = $_FILES["icon"];

             $info = $upload->upload();

             if(count($info)>0){

                 $CourseModel->icon = $info["path"];

             }

         }

         $CourseModel->remark = $_REQUEST["remark"];

         $CourseModel->orderBy = $_REQUEST["orderBy"];

         $CourseModel->numb = $_REQUEST["numb"];

         $CourseModel->theKey = $_REQUEST["theKey"];

         $CourseModel->isOpen = $_REQUEST["isOpen"];

         $CourseModel->lastUpdateTime = time();

         echo $CourseModel->insert();

     }

     //修改

         public function updateCourseAction(){

         $CourseModel = new CourseModel($_REQUEST["id"]);

         $CourseModel->title = $_REQUEST["title"];

         $CourseModel->userId = $_REQUEST["userId"];

39         if(!empty($_FILES)){

             $upload = new BaseUploadUtil();

             $upload->createPath();

             $upload->createDatePath();

             $upload->file = $_FILES["defaultImg"];

             $info = $upload->upload();

             if(count($info)>0){

                 $CourseModel->defaultImg = $info["path"];

             }

         }

49         if(!empty($_FILES)){

             $upload = new BaseUploadUtil();

             $upload->createPath();

             $upload->createDatePath();

             $upload->file = $_FILES["icon"];

             $info = $upload->upload();

             if(count($info)>0){

                 $CourseModel->icon = $info["path"];

             }

         }

         $CourseModel->remark = isset($_REQUEST["remark"]) ? $_REQUEST["remark"] : "";

         $CourseModel->orderBy = $_REQUEST["orderBy"];

         $CourseModel->numb = $_REQUEST["numb"];

         $CourseModel->theKey = $_REQUEST["theKey"];

         $CourseModel->isOpen = $_REQUEST["isOpen"];

         $CourseModel->lastUpdateTime = time();

         echo $CourseModel->update();

     }

上面 第 6 ,16 ,39 ,49 直接判断 $_FILES 不正确,  这里 的 有两个字段 上传 图片 .  defaultImage 和 icon

应该 改为  $_FILES["defaultImage"]   和  $_FILES["icon"] .

如下:

     //添加

     public function addCourseAction()

     {

         $CourseModel = new CourseModel();

         $CourseModel->title = $_REQUEST["title"];

         $CourseModel->userId = $_REQUEST["userId"];

  7         if(!empty($_FILES["defaultImg"])){

             $upload = new BaseUploadUtil();

             $upload->createPath();

             $upload->createDatePath();

             $upload->file = $_FILES["defaultImg"];

             $info = $upload->upload();

             if(count($info)>0){

                 $CourseModel->defaultImg = $info["path"];

             }

         }

 17         if(!empty($_FILES["icon"])){

             $upload = new BaseUploadUtil();

             $upload->createPath();

             $upload->createDatePath();

             $upload->file = $_FILES["icon"];

             $info = $upload->upload();

             if(count($info)>0){

                 $CourseModel->icon = $info["path"];

             }

         }

         $CourseModel->remark = $_REQUEST["remark"];

         $CourseModel->orderBy = $_REQUEST["orderBy"];

         $CourseModel->numb = $_REQUEST["numb"];

         $CourseModel->theKey = $_REQUEST["theKey"];

         $CourseModel->isOpen = $_REQUEST["isOpen"];

         $CourseModel->lastUpdateTime = time();

         echo $CourseModel->insert();

     }

     //修改

     public function updateCourseAction()

     {

         $CourseModel = new CourseModel($_REQUEST["id"]);

         $CourseModel->title = $_REQUEST["title"];

         $CourseModel->userId = $_REQUEST["userId"];

 42         if(!empty($_FILES['defaultImg'])){

             $upload = new BaseUploadUtil();

             $upload->createPath();

             $upload->createDatePath();

             $upload->file = $_FILES["defaultImg"];

             $info = $upload->upload();

 49             //删除:

 50             $this->deleteService($CourseModel->defaultImg);

             if(count($info)>0){

                 $CourseModel->defaultImg = $info["path"];

             }

         }

 56         if(!empty($_FILES['icon'])){

             $upload = new BaseUploadUtil();

             $upload->createPath();

             $upload->createDatePath();

             $upload->file = $_FILES["icon"];

             $info = $upload->upload();

 63             //删除:

 64             $this->deleteService($CourseModel->icon);

             if(count($info)>0){

                 $CourseModel->icon = $info["path"];

             }

         }

         $CourseModel->remark = isset($_REQUEST["remark"]) ? $_REQUEST["remark"] : "";

         $CourseModel->orderBy = $_REQUEST["orderBy"];

         $CourseModel->numb = $_REQUEST["numb"];

         $CourseModel->theKey = $_REQUEST["theKey"];

         $CourseModel->isOpen = $_REQUEST["isOpen"];

         $CourseModel->lastUpdateTime = time();

         echo $CourseModel->update();

     }

     //删除

     public function deleteCourseAction()

     {

         $ids = $_REQUEST["ids"];

         for($i=0;$i<count($ids);$i++)

         {

             $CourseModel = new CourseModel($ids[$i]);

             if(!$CourseModel->delete())

             {

                 echo false;

                 return;

             }

 92             //删除:

 93             $this->deleteService($CourseModel->defaultImg);

 94             $this->deleteService($CourseModel->icon);

         }

         echo true;

     }

     //物理删除:

     public function deleteService($address)

     {

         $file = UPLOAD_PATH . $address;

         if (is_file($file)) {

             # code...

             unlink($file);

         }

     }

红色部分是修改的生成器代码:

绿色部分是添加的 物理删除 资源的方法.
