Entering Current Date In A Field Via Form Button?

I am trying to figure out to have the current date populate in table field by using a button on a form and not having much luck.

I have a table with 2 date fields, a 'created' field and a 'received' field. I already have the date set to auto populate for the 'created' field but I don't want the 'received' field to populate until the employee has gone into the database to receive the work.

I know I could have the employee just enter the date, but i want to avoid any typos or people simply forgetting to do it.

Ideally I would love the button to enter the current date into the 'received' field and save the entry, but I fine it needs to be 2 seperate buttons.
