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>

 //$targetDir = 'uploads';

 // 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;

 } 
 // 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)) {

 }
 // 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"}');

 }
 }
 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));
 }
 }
}
