本文实例讲述了thinkPHP5框架整合plupload实现图片批量上传功能的方法。分享给大家供大家参考,具体如下:

在官网下载plupload http://http//www.plupload.com

或者点击此处本站下载。

这里我们使用的是pluploadQueue

在HTML页面引入相应的css和js,然后根据示例代码修改为自己的代码

<link rel="stylesheet" href="/assets/plupupload/css/jquery.plupload.queue.css" rel="external nofollow" type="text/css" media="screen" /><div class="form-box-header"><h3>{:lang("photo")}</h3></div><div class="t-d-in-editor">  <div class="t-d-in-box">    <div id="uploader">      <p>{:lang("plupupload_tip")}</p>    </div>    <div id="uploaded"></div>  </div></div><script type="text/javascript" src="/assets/plupupload/plupload.full.min.js"></script><script type="text/javascript" src="/assets/plupupload/jquery.plupload.queue.js"></script><script type="text/javascript">$(function() {// Setup html5 version$("#uploader").pluploadQueue({// General settingsruntimes : "html5,flash,silverlight,html4",url : "{:url("photo/upphoto")}",chunk_size: "1mb",rename : true,dragdrop: true,filters : {// Maximum file sizemax_file_size : "10mb",// Specify what files to browse formime_types: [{title : "Image files", extensions : "jpg,gif,png"}]},// Resize images on clientside if we canresize : {width : 320, height : 240, quality : 90},flash_swf_url : "/assets/plupupload/Moxie.swf",silverlight_xap_url : "/assets/plupupload/Moxie.xap",        init: {            PostInit: function() {              $("#uploaded").html("");            },            FileUploaded : function(uploader , files, result) {              up_image = result.response;              if(up_image != ""){                $("#uploaded").append("<input type="hidden" name="images[]" value=""+up_image+""/>"); //这里获取到上传结果              }            }        }});});</script>

plupload整合:

DIRECTORY_SEPARATOR . $fileName;    // Chunking might be enabled    $chunk = isset($_REQUEST["chunk"]) ? intval($_REQUEST["chunk"]) : 0;    $chunks = isset($_REQUEST["chunks"]) ? intval($_REQUEST["chunks"]) : 0;    // Remove old temp files     if ($cleanupTargetDir) {        if (!is_dir($targetDir) || !$dir = opendir($targetDir)) {            die("{"jsonrpc" : "2.0", "error" : {"code": 100, "message": "Failed to open temp directory."}, "id" : "id"}");        }        while (($file = readdir($dir)) !== false) {            $tmpfilePath = $targetDir .

最后Controller或Model获取结果并保存

$images = $request->post("images/a"); //这里一定要注意, thinkphp通过name获取post数组时会获取不到数据,需要在name后加/a,表示获取数组详见Request的typeCastmodel("PhotoImage")->query_insert($images, $id);//批量插入图片
/*** 强制类型转换* @param string $data* @param string $type* @return mixed*/private function typeCast(&$data, $type){    switch (strtolower($type)) {      // 数组      case "a":        $data = (array) $data;        break;      // 数字      case "d":        $data = (int) $data;        break;      // 浮点      case "f":        $data = (float) $data;        break;      // 布尔      case "b":        $data = (boolean) $data;        break;      // 字符串      case "s":      default:        if (is_scalar($data)) {          $data = (string) $data;        } else {          throw new InvalidArgumentException("variable type error:" . gettype($data));        }    }}
