  • 1、先引入jquery和插件的css和js,注意先引入jquery
<link href="./css/jquery.upload.min.css" type="text/css" rel="stylesheet" />
<script src="https://cdn.staticfile.org/jquery/3.1.0/jquery.min.js"></script>
<script src="./js/jquery.upload.min.js"></script>
  • 2、HTML结构
<div class="upload-box1"></div>

<div class="upload-box2"></div>
  • 3、插件配置
    fileInput: 'file1', //上传按钮名,即input[type=file]的name值
    postUrl: './upload1.php', //上传的服务器地址

    fileInput: 'file2', //上传按钮名,即input[type=file]的name值
    postUrl: './upload2.php', //上传的服务器地址
  • 4、服务端处理



$file = $_FILES["file1"]; // 要和配置里的fileInput保持一致
if(!isset($file['tmp_name']) || !$file['tmp_name']) {
    echo json_encode(['code' => 401, 'msg' => '没有文件上传']);
    return false;
if($file["error"] > 0) {
    echo json_encode(['code' => 402, 'msg' => $file["error"]]);
    return false;

$upload_path = dirname(__FILE__) . "/uploads/" . date('Ymd/');
$file_path   = "./uploads/" . date('Ymd/');

if(!is_dir($upload_path) && !mkdir($upload_path, 0777, true)){
    echo json_encode(array('code' => 403, 'msg' => '上传目录创建失败,请确认是否有权限'));
    return false;

if(move_uploaded_file($file["tmp_name"], $upload_path.$file['name'])){
    echo json_encode(['code' => 200, 'src' => $file_path . $file['name']]);
    return true;
    echo json_encode(['code' => 404, 'msg' => '上传失败']);
    return false;

推荐使用 easyhttp——轻量级、语义化、 对 IDE 友好的 HTTP 客户端 来处理
