Question

i am sending 5 different data across to a php file through POST method. the data is all integers. i want to add up all these integer values to produce a sum.

    $.post(
        "user_submit.php", 
        {score: $('#ques'+qn).find('input[name=vote]:checked').val() }, 
        function(data){
            $("#ques"+qn).hide();
            ++qn;
            $("#ques"+qn).show();
        });
    });

in the php file:

$score = $_POST['score'];
$total = $total + $score;
echo $total;

it is not adding up the values. what am i doing wrong?

Answer 1

If you were to print_r($_POST['score']), you would see that it’s actually an array, not a single value. Try something like $total += array_sum($_POST['score']); instead.
