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：

        }
        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\"}\');

        rename(\"{$filePath}.part\", $filePath);

    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));
        }
    }
}
