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。

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：

    $uploads = config('uploads_dir');
    if(!empty($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

    } elseif (!empty($_files)) {

    } else {

    }

    $chunks = isset($_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));
        }
    }
}
