Answer 1

document.getElementByName not a javascript function, try document.getElementById() instead

You can do this

Javascript:

function myFunction() {
var boiler = document.getElementById("boiler").value;
var niamh = document.getElementById("niamh").value;
// Returns successful data submission message when the entered information is stored in database.

// i dont practice using url string in ajax data as it can be compromised with a quote (') string, instead i am using json

// AJAX code to submit form.
    $.ajax({
    type: "POST",
    url: "updateDB.php",
    data: {
       boiler: boiler,
       niamh: niamh
    },
    cache: false,
    }).done(function() {
        alert('success');
    }); // i do this because some jquery versions will deprecate the use of success callback
}

And you are getting to a post so change the $_GET in you php file to $_POST
