通过第三方链接将数据写入 Google 表格中的单元格

Question

How do I make a link that adds data to a Google Sheet?

I am working on a student calling system that allows the following: 1-Parents arrive at our school's entrance and show a QR Code 2-The QR Code is a link that specifies their child's name, year, etc. 3-That data is then sent to a Google Sheet that is being displayed in our assembly hall so the student knows their parent has arrived

It seems like this should work, but I'm missing something: Allowing for third party updates to Google Spreadsheets via email response?

I understand (and can do) how to write a Script and publish as a WebApp, and even to add parameters to that WebApp that are passed as variables, but how do I choose which Google Sheet document to add the data to?

Since this is still conceptual, I don't have any examples, but would greatly appreciate some guidance. I have a decent understanding of coding/scripts, but I'm no expert.

Answer 1

I have figured it out. I was trying to write the Google Sheet WebApp in a seperate document, but I have now added it to the same document. Here is what I did:

In a Google Sheet - Go to Extensions - Apps Scripts

Use the following code in Code.gs:

function doGet(request) {
  Logger.log(request);
  
  var sheet = SpreadsheetApp.getActive().getSheetByName('Sheet1');
  var data = sheet.getDataRange().getValues();
  
  var user = request.parameters.id;
  var year = request.parameters.year;
  for (var i=1; i<data.length; i++) {
    if (data[i][0] == user[0]){
      sheet.getRange(i+1, 3,1,1).setValue(year[0]);
    }
  }
  var result = "Congratulations! You just said '" + year[0] + "' to " + user + ".";

  var cell = sheet.getRange(1,1);
  cell.setValue(year);
  var cell = sheet.getRange(1,2);
  cell.setValue(user);

  return ContentService.createTextOutput(result);
}

Then Deploy - New Development - Choose WebApp

Copy the WebApp URL and add?id=John&year=9 to the end like this: https://script.google.com/macros/s/AKfymany numbercj/exec?id=John&year=9

Put that into a QR code generator and when that code is scanned, the name appears in the Google Sheet document.

When I looked at the original example, it appeared that two Google Sheet documents were being used, so I couldn't see the link between the two. In fact the scpript that becomes a WebApp is attached to the same Google Sheets document.

Thanks again for the responses.
