Google Sheets - multiple columns with auto timestamp - google-apps-script

Question

I am creating a sheet that once a job is assigned to someone, the time is automatically input to the cell beside it.... and when complete, the time is automatically put into the cell beside that one.
I have included a picture of the idea I am going for. Any help would be appreciated. Thanks!

Answer 1

If you set the trigger, it should be enough for you to + adjust the condition there.
I don´t know, when you need fixed date?
function insert_timestamp() {
var s = SpreadsheetApp.getActiveSheet();
var r = s.getActiveCell();
var tz = Session.getScriptTimeZone();
if( r.getColumn() != 0 ) {
var row = r.getRow();
var time = new Date();
time = Utilities.formatDate(time, tz, "dd.MM.yyyy");//"dd.MM.yyyy hh:mm:ss");
SpreadsheetApp.getActiveSheet().getRange('C' + row.toString()).setValue(time);
}
}

There is an onEdit trigger for the SpreadsheetApp which you can use. Basically, every time you edit a cell, the onEdit function runs and passes and event. You can then check that event against some criteria and gof rom there. The documentation below does not seem up to date, but the code did work for me. Finally, you can then select how you want the date displayed using the format settings in the Spreadsheet.
function onEdit( event ) {
const currentRow = event.range.rowStart;
const currentCol = event.range.columnStart;
const value = event.value
// if it is in in Column F (6) or Column H (8)
// you could also check the value here against something
if( currentCol === 6 || currentCol === 8 ){
// put the current time in the column next to the current one
SpreadsheetApp.getRange( currentRow, currentCol + 1).setValue( new Date() )
}
}
See here for reference: onEdit

I have tried this code below to add time stamps just to 6 and 8. but it input a time stamp beside every cell i edit..
function onEdit() {
var s = SpreadsheetApp.getActiveSheet();
if( s.getName() == "Work Orders" ) { //checks that we're on Sheet1 or not
var r = s.getActiveCell();
if( r.getColumn() == 6, 8 ) { //checks that the cell being edited is in column A
var nextCell = r.offset(0, 1);
if( nextCell.getValue() === '' ) //checks if the adjacent cell is empty or not?
nextCell.setValue(new Date());
}
}
}
