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

<script type="text/javascript">

  layui.use('upload', function() {

    var $ = layui.jquery,

      upload = layui.upload;

    //多文件列表示例

    var demoListView = $('#demoList'),

      uploadListIns = upload.render({

        elem: '#testList',

        url: "{url('pic/index/upload')}",

        accept: 'images',

        acceptMime: 'image/*',

        size: 8192,

        multiple: true,

        number: 400,

        auto: false,

        exts: 'jpg|png|jpeg',

        bindAction: '#testListAction',

        choose: function(obj) {

          var files = this.files = obj.pushFile(); //将每次选择的文件追加到文件队列

          //读取本地文件

          obj.preview(function(index, file, result) {

            var tr = $(['<tr id="upload-' + index + '">', '<td>' + file.name + '</td>', '<td><img src="/UploadFiles/2021-04-02/' + result + '">

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{

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

    }

    $n=$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));

    }else{

      exit(json_encode(array("code"=>1,"msg"=>"false","file"=>$n,"size"=>$file['size']),0));

    }

  }
