Collecting a Gmail Username when a Button is Pressed In Google Sheets - google-apps-script

Question

I am creating a bathroom sign out sheet for my middle school students. I have created a Google App Script that Collects students names from a dropdown box and then logs the date and time. Everything seems to work great except when 500 students have access to the sheet at the same time. If a student selects their name it can possibly change before the script can be run. I would like to replace the dropdown box with a script that will automatically grab their Google User Name. Is there anyway this can be done? I am a novice programmer and tend to get things to work by tinkering around with it, but this seems to be above my head. Here is the Google Sheet and the Script is attached as well. Thanks in advance

Answer 1

This works for me:
function getUserEmail() {
SpreadsheetApp.getActive().toast(Session.getActiveUser().getEmail());
}
But it may not work all of the time because of a complex set of security protocols which I know nothing about.

Answer 2

Since you are pertaining to the email address of the user, you can use Session.getActiveUser() which will give you the current user, then use getEmail() to get the current user's email address. Similar to what #Cooper suggested
You just need to use them in your clockIn() and clockOut():
function clockIn()
{
//DEFINE ALL ACTIVE SHEETS
var ss = SpreadsheetApp.getActiveSpreadsheet();
//DEFINE MAIN SHEET
var mainSheet = ss.getSheetByName("DATASHEET");
//LAST ROW ON MAIN SHEET
var lastRow = mainSheet.getLastRow();
for (var j = 5; j <= lastRow; j++)
{
// CHECK CLOCK IN
if(Session.getActiveUser().getEmail() == mainSheet.getRange(j, 1).getValue() && mainSheet.getRange(j,3).getValue() == '')
{
Browser.msgBox("⚠️ You are Already Signed Out","Please Click the Returning to Classroom Button and then Try Again!",Browser.Buttons.OK);
return;
}
}
//_________________________________________________________________________________________________________________________________________________//
// ADD CLOCK IN RECORD
mainSheet.getRange(lastRow+1,1).setValue(Session.getActiveUser().getEmail()).setFontSize(12);
mainSheet.getRange(lastRow+1,2).setValue(new Date()).setNumberFormat("MM/dd/yyyy hh:mm:ss A/P").setHorizontalAlignment("left").setFontSize(12);
//CLEARCONTENTS
{
var sheet = ss.getSheetByName("MAIN");
sheet.getRange('B1:B2').clearContent();
}
if (Session.getActiveUser().getEmail() == Session.getActiveUser().getEmail() && mainSheet.getRange(j,3).getValue() == '')
{
SpreadsheetApp.getUi().alert("⏰ Please Hurry Back! ⏰","Your Teacher is Waiting",SpreadsheetApp.getUi().ButtonSet.OK);
}
}
//_________________________________________________________________________________________________________________________________________________//
function clockOut() {
//DEFINE ALL ACTIVE SHEETS
var ss = SpreadsheetApp.getActiveSpreadsheet();
//DEFINE MAIN SHEET
var mainSheet = ss.getSheetByName("DATASHEET");
//LAST ROW ON MAIN SHEET
var lastRow = mainSheet.getLastRow();
var foundRecord = false;
for (var j = 5; j <= lastRow; j++)
{
// FIND CLOCK IN RECORD
if(Session.getActiveUser().getEmail() == mainSheet.getRange(j, 1).getValue() && mainSheet.getRange(j,3).getValue() == '')
{
SpreadsheetApp.getUi().alert("🙏 Thank You! 🙏"," " ,SpreadsheetApp.getUi().ButtonSet.OK);
// UPDATE CLOCK IN RECORD
mainSheet.getRange(j,3).setValue(new Date()).setNumberFormat("MM/dd/yyyy hh:mm:ss A/P").setHorizontalAlignment("left").setFontSize(12);
var totalTime = (mainSheet.getRange(j,3).getValue() - mainSheet.getRange(j,2).getValue()) /(60*100*1000);
mainSheet.getRange(j,4).setValue(totalTime.toFixed(2)).setNumberFormat("#0.00").setHorizontalAlignment("left").setFontSize(12);
foundRecord = true;
}
}
//CLEARCONTENTS
{
var sheet = ss.getSheetByName("MAIN");
sheet.getRange('B1:B2').clearContent();
}
// IF NO CLOCK IN RECORD
if(foundRecord == false)
{
SpreadsheetApp.getUi().alert("⚠️ No Record ⚠️","You Might Have Forget to Sign Out?" ,SpreadsheetApp.getUi(). ButtonSet.OK);
}
}

Another option is to use promt dialog to ask user to input their name when clockIn() or clockOut() was called. Then change the inputted name to capital letters.
Your Code:
function clockIn()
{
//DEFINE ALL ACTIVE SHEETS
var ss = SpreadsheetApp.getActiveSpreadsheet();
//DEFINE MAIN SHEET
var mainSheet = ss.getSheetByName("DATASHEET");
//LAST ROW ON MAIN SHEET
var lastRow = mainSheet.getLastRow();
var ui = SpreadsheetApp.getUi();
var response = ui.prompt('Enter your name:',ui.ButtonSet.OK_CANCEL);
var studentName;
// Process the user's response.
if (response.getSelectedButton() == ui.Button.OK) {
Logger.log('The user\'s name is %s.', response.getResponseText());
studentName = studentName.toUpperCase();
studentName = response.getResponseText();
} else {
Logger.log('Request was cancelled.');
return;
}
for (var j = 5; j <= lastRow; j++)
{
// CHECK CLOCK IN
if(studentName == mainSheet.getRange(j, 1).getValue() && mainSheet.getRange(j,3).getValue() == '')
{
Browser.msgBox("⚠️ You are Already Signed Out","Please Click the Returning to Classroom Button and then Try Again!",Browser.Buttons.OK);
return;
}
}
//_________________________________________________________________________________________________________________________________________________//
// ADD CLOCK IN RECORD
mainSheet.getRange(lastRow+1,1).setValue(studentName).setFontSize(12);
mainSheet.getRange(lastRow+1,2).setValue(new Date()).setNumberFormat("MM/dd/yyyy hh:mm:ss A/P").setHorizontalAlignment("left").setFontSize(12);
//CLEARCONTENTS
{
var sheet = ss.getSheetByName("MAIN");
sheet.getRange('B1:B2').clearContent();
}
if (studentName == studentName && mainSheet.getRange(j,3).getValue() == '')
{
SpreadsheetApp.getUi().alert("⏰ Please Hurry Back! ⏰","Your Teacher is Waiting",SpreadsheetApp.getUi().ButtonSet.OK);
}
}
//_________________________________________________________________________________________________________________________________________________//

var ss = SpreadsheetApp.getActiveSpreadsheet();
//DEFINE MAIN SHEET
var mainSheet = ss.getSheetByName("DATASHEET");

var lastRow = mainSheet.getLastRow();
var foundRecord = false;
var ui = SpreadsheetApp.getUi();
var response = ui.prompt('Enter your name:',ui.ButtonSet.OK_CANCEL);
var studentName;
// Process the user's response.
if (response.getSelectedButton() == ui.Button.OK) {
