Upload de arquivos

crhistianosa · Março 14, 2017

Estou tentando através do Google Script criar um formulário em que haja alguns botões para upload de arquivos em que eles irão direto para o Google Drive. Estou usando um código que obtive na internet, porém preciso adicionar mais botões para anexar arquivos. Consegui, mas só vai um arquivo para o Google Drive.

Segue o código do arquivo "forms.html":

<!DOCTYPE html>
<html>
  <head>
    <base target="_blank">
    <meta name="viewport" content="width=device-width, initial-scale=1.0" />
    <title>Google File Upload by CTRLQ.org</title>
