Adding a value from a text box without a Form Submit

Experts, in a related post, I received a solution of listing out the 2 teams for different games.
There is a "Choose!" button next to each team which:
-  Allows the user to Choose one of the 2 teams
-  Inserts that Choice into the database with the

<input type="submit" value="Choose!" onClick="_submit('<?=$gameid?>','<?=$fav?>')";>

Since each line has it's own submit button, the Form itself does not have one.
This has been working fine, but...

Recently, I realized that I needed to add ONE text field to allow the users to type in the total number of points (INT) as a tiebreaker...

Something like this:
echo "<CENTER>For Tiebreaker, Enter total points in Game #10 above: <input name='Tiebreaker' type='text' size='5' maxlength='5'></CENTER>";      

Since the form itself doesn't have a submit button, I would like to
-  Have the user enter their number in the box
-  Click a SUBMIT NUMBER button right next to the text box
-  Have the number insert into the database
INSERT INTO TIEBREAKERS SET
userid = '$MemberID'
tiebreaker = //Number from the Text Box

-  And have the text box show the chosen number after it's entered into the database (in case the user wants to change it)

Thanks in advance,

-Dan
<script>
function _submit(teamid,selection) {
document.form.teamid.value=teamid;
document.form.selection.value=selection;
}

function validateForm(frm) {
	alert(frm.teamid.value + "\n\n" + frm.selection.value);
	return false;
}
</script>


if($_POST) {
 
$finalPID = $_POST["teamid"];
$finalselection = $_POST["selection"];

//add to database
//refresh page

}

<input type="submit" value="Choose!" onClick="_submit('<?=$gameid?>','<?=$fav?>')";>

You can't. As far as I know, since a query has to run on server side, you must pass through the server, that is you must post a form. I have to ask: you have only one form with several submit input or you have several form each with its own submit input?

Anyway, I would suggest to change  the logic of your app: use only one form, replace choose buttons with radios and place in the bottom yout text box for tiebreaker. Finally a beautiful submit button wich pass both choosen team and tiebreak value to insert them in db. Could you consider to use this design pattern?

Looks like AJAX was definitely the way to go here...
