I would like to create a simple google site with a list of names, however I would like to keep the email addresses hidden from the users. I would like to create a basic list with names like Joe S and then an "email Joe S: link right next to his name. By clicking the link the user could email Joe S. My perfect scenario, would be to allow the user to multi select since some users may want to send a message to 2 of the 5 people in the list. The list will never be more than 40 people. I guess let's start with the basics, how can I accomplish the email task?

Hi Mr Bond,

I'll try to get some time later to write a full how-to, but I think an easy approach would be:

1. Create a Google Spreadsheet
2. Create a form with checkboxes as per http://climbtothestars.org/archives/2009/09/06/google-forms-multiple-choice-list-checkbox/
3. Create an OnSubmit script to email the "ticked" people: http://code.google.com/googleapps/appsscript/articles/sending_emails.html
4. Embed the form in the site

You could also do everything using Apps Script UI, or create a custom gadget and embed that...

Like I said, hoping to get a bit of time in the next day or two, but hope the above helps.

I created a spreadsheet with 2 rows, email in column A and message in column B. I am able to work through this example as long as the data stays only in columns A and B.


However, I am not able to figure out how to "relate" the check boxes in the form to the names in the spreadsheet. How to I take input from the form into my script? How do I tell the script to take the check boxes as input, then match on the text of the name, and execute?

Hi SQLAgent,

This is kinda messy code, but if you create a sheet with the form, then add a sheet called 'Names' that has Name and Email columns (in that order), then you can create a script as per below, triggered on form submit. Assumes your list of names to email ends up in the B column. You can have Subject etc in the other cells, just reference them with getRange to set the subject, body. Make sure the trigger is using myFunction, too.


function myFunction() {
  var sheet = SpreadsheetApp.getActiveSheet();
  sheet.sort(1, false);
  var people = sheet.getRange('B2').getValue().split(', ');
  for (i in people)
  {
    var addr = findName(people[i]);
    MailApp.sendEmail(addr, 'Hi', addr);
  }
  
}


function findName(v) {
  var sh = SpreadsheetApp.getActiveSpreadsheet().getSheetByName('Names');
  var r = sh.getDataRange().getValues();
  for(i in  r)
  {
     if(r[i][0] == v)
       return r[i][1];
    
  }
  return '';
  
}

This is awesome!!!! The only challenge I am having now is getting the [Enter eMail Message] data into the body of the email. I notived this line:
MailApp.sendEmail(addr, 'Hi', addr);
Is putting the email address in the body.

The only tricky part is that the email address is on the second sheet named [Names], however the message body is on the first sheet named [Sheet1]. I am getting the impression that sheet [names] is just like a lookup table in a database. How can I assign the [Sheet1].[ColumnC] to a varable and put that variable in the body of the email messsage?

I have attache screenshots.... This is the form, I have added txt to the jpgGoogle-Spreadsheet-w-2-tabs.jpg

After the line
sheet.sort(1, false);

insert

var bd = sheet.getRange('C2').getValue()

and then instead of

MailApp.sendEmail(addr, 'Hi', addr);

put

MailApp.sendEmail(addr, 'Hi', bd);


By the way, you could similarly repalce 'Hi' with a subject by adding it to your form - then just have a look at which columns represent which variable. For instance, if Subject is after Contents, it'll probably end up being D. And the line is always 2 because we're sorting the data by time (descending) before picking up the values. Hope that makes sense.

Oops - missed a ';' on the var bd = ... line.
