学习ThinkPHP5很长时间了,任何上传图片的系统都是必不可少的,今天错新技术频道小编简要总结了thinkphp5框架集成plupload实现图像批量上传的功能,希望对你学习这方面知识有帮助!

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

 

{:lang('photo')}

{:lang('plupupload_tip')}

 

plupload整合:

<?php/*  * 文件上传 *  * Donald * 2017-3-21 */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($_REQUEST["chunks"]) : 0;    // Remove old temp files     if ($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));        }    }}
