Insert uploaded files names into a MySQL database

 I do not know how to retrieve uploaded files names (I want to insert them into a MySQL database).

I do not know how to modify line 15 [here](https://github.com/ngoduykhanh/flask-file-uploader/blob/master/templates/index.html):

```
<form id="fileupload" action="//jquery-file-upload.appspot.com/" method="POST" enctype="multipart/form-data">
```
