Feature request: Handle file upload from forms

[taophp]

May I missed something somewhere, but I can't figure how to handle file upload with xtemplate. If I'm wrong, tell me. If I'm right, well, we might figure out how to implement it. It seems a requirement for a modern web app framework.

Yes I definitely want to have file upload support.

Here's an idea for a design:

Add another method onto the DotFS like

{{$dirName := .FS.ReceiveFiles "./dir" $maxfiles $maxbytes}}
{{range .FS.ListFiles $dirName}}
    ...

It would create a new directory under dir with a random name and save all multipart form files there as long as they are within the limits. This would guarantee that each request gets its own dir and can't clash with an existing directory.

Here are a few references:

• How to process file uploads in Go
• go - How can I receive an uploaded file using a Golang net/http server? - Stack Overflow

I may work on this after the dot provider system is ready.

It seems a very good solution !

@infogulch I don't if that can be helpful, I've just discovered this Caddy module: https://github.com/git001/caddyv2-upload

@gedw99 What uploading have to do with distributing ?

@gedw99 I think this module could make the work. It should be documented somewhere in the xtemplate module doc.
@infogulch May be we should close this issue?

I would like to include this feature as part of the writable FS #36, but we can close this for now.
