php layui实现前端多图上传实例


						php结合layui前端实现多图上传



前端html代码





<div class="layui-upload">



  <button type="button" class="layui-btn layui-btn-normal" id="testList">请选择图片</button>



  <span class="num_pic"></span>



  <div class="layui-upload-list">



    <table class="layui-table">



      <thead>



        <tr>



          <th>文件名</th>



          <th id="pic">图片预览</th>



          <th>大小</th>



          <th>状态</th>



          <th id="cao">操作</th>



        </tr>



      </thead>



      <tbody id="demoList"></tbody>



    </table>



  </div>



  <button type="button" class="layui-btn" id="testListAction">开始上传</button>



    <span class="num_pic"></span>



</div>



js 代码

后端代码





public function uploadAction(){



    $file=$_FILES['file'];



    $root_url = 'uploadfiles/pic/image/';



    if (!is_uploaded_file($file['tmp_name'])){



      $data = array('code'=>1,'msg'=>"错误");



      exit(json_encode($data,0));



    }



   /* $root_url.=date('Ymd').'/';*/



    $ext = pathinfo($file['name']);



    $num=makenum($this->memberinfo['id']);



    $root_url.=$num.'/';



    if (!is_dir($root_url)) {



      mkdir($root_url,0777, true);



    }



    $pa=file_list::get_file_list($root_url);



    $na=count($pa) + 1;



    if ($na<10){



      $name=$num.'-000'.$na;



    }elseif($na<100){



      $name=$num.'-00'.$na;



    }elseif($na<1000){



      $name=$num.'-0'.$na;



    }else{

    }



    $n=$root_url.$name.".".$ext['extension'];



    $result=move_uploaded_file($file['tmp_name'],$n);



    if ($result){



      exit(json_encode(array("code"=>0,"msg"=>"ok","file"=>$n,"size"=>$file['size']),0));
