I know there are existing codes to build a form that can upload multiple files (bulk import) such as this Uploading Multiple Files to Google Drive with Google App Script, but I was just wondering if it's possible to do one that asks for bulk import (or big sized file) multiple times? The existing scripts seem to pass the id of one input in the upload function using document.getFileByID(), and I can't pass multiple id's in it.
Here are the codes that I was referring to (copied from Uploading Multiple Files to Google Drive with Google App Script):
function doGet() {
return HtmlService.createHtmlOutputFromFile('form')
.setSandboxMode(HtmlService.SandboxMode.IFRAME);
}
function uploadFileToDrive(base64Data, fileName) {
try{
var splitBase = base64Data.split(','),
type = splitBase[0].split(';')[0].replace('data:','');
var byteCharacters = Utilities.base64Decode(splitBase[1]);
var ss = Utilities.newBlob(byteCharacters, type);
ss.setName(fileName);
var dropbox = "Something"; // Folder Name
var folder, folders = DriveApp.getFoldersByName(dropbox);
if (folders.hasNext()) {
folder = folders.next();
} else {
folder = DriveApp.createFolder(dropbox);
}
var file = folder.createFile(ss);
return file.getName();
}catch(e){
return 'Error: ' + e.toString();
}
}
