As part of a production, I've created an HTML page to upload files. My page has a button that lets me import the file, and a "Send" button that lets me send the file.
For the time being, I've made sure that when I press "Send", a new window appears for writing a new e-mail on Roundcube.
So I wanted to know if there was a plugin or function that would allow me to make sure that as soon as I press "Send" (after importing the file to be sent), my new window for writing appears with the file already attached.
I tried using the Roundcube API, but couldn't figure out how to use it, even after reading the documentation.
For the moment my code is pretty simplistic (it's just forms) so I don't see the point of posting it
(I've also already posted a topic on the roundcube forum but I've had no response so that's why i'm asking here)
