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;

// Open temp file
if (!$out = @fopen("{$filePath}.part", $chunks ? "ab" : "wb")) {

}
@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

}
}
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));
}
}
}
