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
{:lang(photo)}
{:lang(plupupload_tip)}
$(function() {// Setup html5 version$("#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(""); //这里获取到上传结果 } } }});});
plupload整合：
<?php/* * 文件上传 * * Donald * -3-21 */namespace app\backend\logic;use think\Model;class Plupupload extends Model{ public function upload_pic($file_type="data"){ #!!

DIRECTORY_SEPARATOR . $fileName; // Chunking might be enabled $chunk = isset($_REQUEST["chunk"]) ? intval($_REQUEST["chunk"]) : 0; $chunks = isset($_REQUEST["chunks"]) ? intval($_REQUEST["chunks"]) : 0; // Remove old temp filesif ($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 : $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)); } }}
基于ThinkPHP5.0实现图片上传插件
ThinkPHP框架中使用Memcached缓存数据的方法
