Show POST information from ajax success

For a project I have, I need to write all the code on one page and finding it very challenging. I need ajax, js and PHP but am not allowed to reload the page. I currently have everything working after 6 hours but I want to show a message below my submit button with the information a person has entered into the form. I have looked at ajax success and was thinking is their a way to do it via that or even better just have a div place holder with the id of #message that will change to the information in my POST.

This is my current ajax and js

function myFunction() {
        var title = document.getElementById("title").value;
        var firstname = document.getElementById("firstname").value;
        var lastname = document.getElementById("lastname").value;
        var address = document.getElementById("address").value;
        var teleno = document.getElementById("teleno").value;
        var email = document.getElementById("email").value;
        var dataString = 'title1=' + title + '&firstname1=' + firstname + '&lastname1=' + lastname + '&address1=' + address + '&teleno1=' + teleno + '&email1=' + email;
        if (title == '' || firstname == '' || lastname == '' || address == '' || teleno == '' || email == '') {
            alert("Please Fill All Fields");
        } else {
            $.ajax({
                type: "POST",
                url: "index.php",
                data: dataString,
                cache: false,
                success: function(information) {
                    alert(html);
                }
            });
        }
        return false;

along with my php, I’m just using this code so I can make sure the data is actually going into my tables.

$title = mysqli_real_escape_string($conn, $_POST['title1']);
$firstname = mysqli_real_escape_string($conn, $_POST['firstname1']);
$lastname = mysqli_real_escape_string($conn, $_POST['lastname1']);
$address = mysqli_real_escape_string($conn, $_POST['address1']);
$teleno = mysqli_real_escape_string($conn, $_POST['teleno1']);
$email = mysqli_real_escape_string($conn, $_POST['email1']);

if (isset($_POST['title1'])) {
    $sql = "INSERT INTO form (title, firstname, lastname, address, teleno, email) VALUES ('$title','$firstname','$lastname','$address','$teleno','$email')";
    $count = mysqli_num_rows($result);

    if (mysqli_query($conn, $sql)) {
    } else {
        echo "Error: " . $sql .
            "<br>" . mysqli_error($conn);
    }
}

$sql2 = "Select * From form";

$result = mysqli_query($conn, $sql2);

$contacts = array();
while ($row = mysqli_fetch_array($result)) {
    $contacts[] = $row;
}
mysqli_close($conn);
foreach ($contacts as $contact) :

    echo $contact["id"] . " ";
    echo $contact["title"] . " ";
    echo $contact["firstname"] . " ";
    echo $contact["lastname"] . " ";
    echo $contact["address"] . " ";
    echo $contact["teleno"] . " ";
    echo $contact["email"] . " ";
    echo "<br>";

endforeach;
