 </span>
  </if>
   </p>
   <p class="space-4"></p>
   <p id="imgError" class="msg"></p>
    </p></p>

CSS：

<style>
    .remove-uploadimg{ cursor:pointer;}
    .uploadimg{
   display: inline-block;
   position: relative;
    }
    .uploadimg .remove-uploadimg{
   position: absolute;
   font-size: 20px;
   top:-10px;
   right: -6px;
    }
    .remove-uploadimg{
   width:30px;
   height:30px;
   background-color:#ccc;
   border-radius:50%;
   color:red;
   text-align:center;
    }
    .remove-uploadimg:hover{
   text-decoration: none;
    }</style>

JS：

<script src="__PUBLIC__/js/mbUploadify.js"></script>
<script>    var upload1 = new mbUploadify({
   file: document.getElementById('imgfile'),   /*ajax 上传地址*/
   url: "{:U('Upload/mbUploadImg')}",   //上传进度
   progress: function(){
  $('#imgpath').show();
  $('#imgpath').val('上传中...');
   },   /*上传失败*/
   error: function(file, msg){
  document.getElementById('imgError').innerHTML = msg;
   },   /*ajax上传成功*/
   uploadSuccess: function(res){
  $('#imgpath').hide();
  $('#imgpath').val('');  var data = JSON.parse(res);
  document.getElementById('img-data').innerHTML = '<span class="uploadimg">' +
'<img src="'+ data.savepath +'" style="max-width: 300px;">' +
'<input type="hidden" name="img" value="'+data.id+'">'+
'<a class="remove-uploadimg" title="删除">✕</a>' +
'</span>';
   }
    });
    $('body').on('click','.remove-uploadimg',function(){
   $(this).parents('.uploadimg').remove();
    })</script>

PHP：

public function mbUploadImg(){    $upload = new Upload(); // 实例化上传类
    $upload->maxSize = 5242880 ; // 设置附件上传大小
    $upload->exts = array('jpg', 'gif', 'png', 'jpeg'); // 设置附件上传类型
    $upload->rootPath =  './Public/';    // 上传文件
    $info = $upload->uploadOne($_FILES['files']);    if($info) {   // 上传成功
   $data['name'] = $info['name'];   $data['ext'] = $info['ext'];   $data['type'] = $info['type'];   $data['savename'] = $info['savename'];   $data['savepath'] = "/Public/".$info['savepath'].$info['savename'];   $imgId = M('upload_img')->add($data);   if($imgId){  $resData['code'] = 200;  $resData['msg'] = '成功';  $resData['id'] = $imgId;  $resData['name'] = $data['name'];  $resData['savepath'] = $data['savepath'];  echo json_encode($resData);  return;
   }
    }    // 上传错误提示错误信息
    return $this->ajaxReturn(['code'=>400,'msg'=>$upload->getError()]);
}
