How to upload file?

It's possible to upload a file to server like "multipart/form-data"?

Well you can definitely do that with LuaSocket:
http://stackoverflow.com/questions/12202301/upload-file-to-a-server-using-lua
You just need to include socket.lua file to your project. You can find socket.lua file in your Gideros installation folder, inside All Plugins/LuaSocket/source
Maybe will need to include other LuaSocket files from the same folder, didn't check.

But I think it might also be possible to do it with UrlLoader in the same way, by simply using POST and reading in the file and setting header to "multipart/form-data"

I searched a lot and did several tests using this code as a basis, but the file was not going along with the message to the server. If I find the solution I'll post here.

Hello, this one seems to work for me:

local filename = "crate.png" local file = io.open(filename, "rb") local contents = file:read( "*a" ) local boundary = "somerndstring"   local send = "--"..boundary.. "\r\nContent-Disposition: form-data; ".. "name="..filename.."; filename="..filename.. "\r\nContent-type: image/png".. "\r\n\r\n"..contents.. "\r\n--"..boundary.."--\r\n";   local headers = { ["Content-Type"] = "multipart/form-data; boundary="..boundary, ["Content-Length"] = #send, }   local loader = UrlLoader.new("<a href="http://localhost/gideros.php"" rel="nofollow">http://localhost/gideros.php"</a>, UrlLoader.POST, headers, send)   loader:addEventListener(Event.COMPLETE, function(e) print(e.data) end)
