**controller中：**

//修改检测
    	    public function pinpai_modi_check(){
    	    	$file[0]=$_FILES['logo'];											//对应图片的name
    	    	$file[1]=$_FILES['joinpic'];										
    	    	if(!empty($file[0]['name'])){										//var_dump($file)即可看到键名name
    	    		$pic1='./Uploads/'.I('logo1');									//获取原图路径
    	    		$pic1=iconv('utf-8','gbk',$pic1);								//转换编码，否则中文名文件无法删除
    	    		unlink($pic1);													//删除之前的图片
    	    	}
    	    	if(!empty($file[1]['name'])){
    	    		$pic2='./Uploads/'.I('joinpic1');								
    	    		$pic2=iconv('utf-8','gbk',$pic2);								
    	    		unlink($pic2);													
    	    	}
    	    	$rel=D('pinpai');
    	    	$rel->create();
    	    	$arr=upload('pinpai');
    	    	$rel->logo=$arr[0];
    	    	$rel->joinpic=$arr[1];
    	    	$rel->save();
    	    	$this->success('修改成功！',U('index/pinpai'));
    	    }

**HTML中：**

<form method="post" action="{:U('index/pinpai_modi_check')}"  enctype="multipart/form-data">
        <ul class="forminfo">
            <input name="id" type="hidden" value="{$info['id']}" /> 
          <li>
            <label>品牌LOGO：</label>
            <input name="logo1" type="hidden" value="{$info['logo']}" />			//原图路径
            <input name="logo" type="file" value="" />
          </li>
          <li>
            <label>加盟图标：</label>
            <input name="joinpic1" type="hidden" value="{$info['joinpic']}" />		//原图路径
            <input name="joinpic" type="file" value="" />
          </li>
        <li><input  type="submit" value="确认保存"/></li>
        </ul>
        </form>
