thinkPHP5框架整合plupload实现图片批量上传

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" />
<p class="form-box-header"><h3>{:lang('photo')}</h3></p>
<p class="t-d-in-editor">
  <p class="t-d-in-box">
    <p id="uploader">
      <p>{:lang('plupupload_tip')}</p>
    </p>
    <p id="uploaded"></p>
  </p>
</p>
<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

    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));
        }
    }
}
