"Blueimp jQuery文件上传"重命名文件 [英] "Blueimp jQuery File Upload" rename files

问题描述

我正在使用Blueimp jQuery文件上传工具.我想在上传文件时完全重命名它们.由于照片是根据用户ID添加到唯一目录中，因此我真的只想添加名称为001.jpg，002.jpg，003.jpg等的照片.如何做到这一点(可以通过修改UploadHandler来实现). php或index.php?

I'm using the Blueimp jQuery file upload tool. I'd like to completely rename the files as they're uploaded. Since photos are being added to a unique directory based on the userID, I'd really just like to add photos with names 001.jpg, 002.jpg, 003.jpg, etc. How can I accomplish this (either by modifying UploadHandler.php or index.php?

在index.php中(下面的代码当前会更改上传目录):

In index.php (code below currently changes the upload directory):

$userID = 'user005'; //hardcoded in this example
$options = array('upload_dir'=>'files/'.$userID.'/', 'upload_url'=>'files/'.$userID.'/');
$upload_handler = new UploadHandler($options);

Old post, but as I was searching the same thing today, I post my solution hoping it will help someone.

我以这种方式编辑UploadHandler.php文件:

I edited the UploadHandler.php file in this way:

        //custom function which generates a unique filename based on current time
        protected function generate_unique_filename($filename = "")
            {

                $extension = "";
                if ( $filename != "" )
                {
                    $extension = pathinfo($filename , PATHINFO_EXTENSION);

                    if ( $extension != "" )
                    {
                        $extension = "." . $extension;
                    }
                }

                return md5(date('Y-m-d H:i:s:u')) . $extension;
            }


            protected function handle_file_upload($uploaded_file, $name, $size, $type, $error,
                    $index = null, $content_range = null) {
                $file = new \stdClass();

                //MYEDIT to generate unique filename
                $file->name = $this->generate_unique_filename($name);

                //ORIGINAL LINE: $file->name = $this->get_file_name($uploaded_file, $name, $size, $type, $error, $index, $content_range);

                //...
}
