thinkPHP5框架整合plupload实现图片批量上传功能的方法

　　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

　　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：

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, $chunks ? ab : wb)) { die({jsonrpc : 2.0, error : {code: 102, message: Failed to open output stream.}, id : id}); } if (!empty($_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)); } } }
