[PHP] thinkPHP5框架整合plupload实现图片批量上传功能的方法

点击文件名下载附件
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：

  }
  $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));
    }
  }
}

希望本文所述对大家基于ThinkPHP框架的PHP程序设计有所帮助。
