Well you should first use radio buttons instead of check boxes. Check boxes allow for multiple selections, and there is only one winner right (unless there is a tie game)?
HTML - Something like this:
<FORM METHOD=POST ACTION="process.php">
<INPUT TYPE="radio" NAME=" game_one" value=team_one>
<INPUT TYPE="radio" NAME=" game_one" value=team_two>
<INPUT TYPE="radio" NAME=" game_two" value=team_three>
<INPUT TYPE="radio" NAME=" game_two" value=team_four>
</FORM>
PHP - Something like this:
<?
$game1winner = $game_one;
$game2winner = $game_two;
//just incase of a tie
If(!($game1winner)
{
$game1winner = "tie game";
}
If(!($game2winner)
{
$game2winner = "tie game";
}
?>
Then you can upload your data to a datafile, database, or print the results on the next page.
<?
echo "Winner from game 1 is ".$game1winner;
echo "Winner from game 2 is ".$game2winner;
?>
