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






plupload整合：

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

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;

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

}
}
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));
}
}
}
