这篇文章主要介绍了thinkPHP5框架整合plupload实现图片批量上传功能的方法,结合实例形式分析了thinkPHP结合pluploadQueue实现上传功能的相关操作技巧,需要的朋友可以参考下。
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 settings
- runtimes : 'html5,flash,silverlight,html4',
- url : '{:url("photo/upphoto")}',
- chunk_size: '1mb',
- rename : true,
- dragdrop: true,
- filters : {
- // Maximum file size
- max_file_size : '10mb',
- // Specify what files to browse for
- mime_types: [
- {title : "Image files", extensions : "jpg,gif,png"}
- ]
- },
- // Resize images on clientside if we can
- resize : {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:
- <?php

- namespace app\backend\logic;
- use think\Model;

- public function upload_pic($file_type="data"){

- // 5 minutes execution time

- $targetDir = $uploads;
- //$targetDir = 'uploads';
- $cleanupTargetDir = true; // Remove old files
- $maxFileAge = 5 * 3600; // Temp file age in seconds
- // Create target dir
- if (!file_exists($targetDir)) {
- @mkdir($targetDir);
- }
- // Get a file name
- if (isset($_REQUEST["name"])) {
- $fileName = $_REQUEST["name"];
- } elseif (!emptyempty($_FILES)) {
- $fileName = $_FILES["file"]["name"];
- } else {
- $fileName = uniqid("file_");
- }
- //重命名文件
- $fileName_arr = explode(".", $fileName);
- $fileName = myrule().".".$fileName_arr[1]; //rule()请查看上篇我的上篇博客thinkphp同时上传多张图片文件重名问题
- $filePath = $targetDir . 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 . DIRECTORY_SEPARATOR . $file;
- // If temp file is current file proceed to the next
- if ($tmpfilePath == "{$filePath}.part") {
- continue;
- }
- // Remove temp file if it is older than the max age and is not the current file
- if (preg_match('/\.part$/', $file) && (filemtime($tmpfilePath) < time() - $maxFileAge)) {
- @unlink($tmpfilePath);
- }
- }
- closedir($dir);
- }
- // Open temp file
- if (!$out = @fopen("{$filePath}.part", $chunks ? "ab" : "wb")) {
- die('{"jsonrpc" : "2.0", "error" : {"code": 102, "message": "Failed to open output stream."}, "id" : "id"}');
- }
- if (!emptyempty($_FILES)) {
- if ($_FILES["file"]["error"] || !is_uploaded_file($_FILES["file"]["tmp_name"])) {
- die('{"jsonrpc" : "2.0", "error" : {"code": 103, "message": "Failed to move uploaded file."}, "id" : "id"}');
- }
- // Read binary input stream and append it to temp file
- if (!$in = @fopen($_FILES["file"]["tmp_name"], "rb")) {
- die('{"jsonrpc" : "2.0", "error" : {"code": 101, "message": "Failed to open input stream."}, "id" : "id"}');
- }
- } else {
- if (!$in = @fopen("php://input", "rb")) {
- die('{"jsonrpc" : "2.0", "error" : {"code": 101, "message": "Failed to open input stream."}, "id" : "id"}');
- }
- }
- while ($buff = fread($in, 4096)) {
- fwrite($out, $buff);
- }
- @fclose($out);
- @fclose($in);
- // Check if file has been uploaded
- if (!$chunks || $chunk == $chunks - 1) {
- // Strip the temp .part suffix off
- rename("{$filePath}.part", $filePath);
- }
- // Return Success JSON-RPC response
- die($filePath); //这里直接返回结果
- // die('{"jsonrpc" : "2.0", "result" : "'.$filePath.'", "id" : "id"}');
- }
- }
最后Controller或Model获取结果并保存
$images = $request->post('images/a'); //这里一定要注意, thinkphp通过name获取post数组时会获取不到数据,需要在name后加/a,表示获取数组详见Request的typeCast
model('PhotoImage')->query_insert($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));
- }
- }
- }
