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 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

    $uploads = config('uploads_dir');

    if(!empty($file_type)){

      $uploads = $uploads .$file_type."/".date("Ymd");

    }

    $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 (!empty($_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 (!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));

        }

    }

}
