Iam trying to pass the value stored in the variable fieldCSV to file data.csv...Ive used javascript and php to do this.. I have triggered an ajax request when a value is stored in to the variable fieldCSV, bt this is nt working as the file that gets downloaded prints the php error inside it instead of csv..

$.ajax({
    type: "POST",
    url: "/test/fileDownload.php",
    data: {
        name: fieldCSV},
});





<?php
$name = $_POST["name"];
header('Content-Type: text/csv; charset=utf-8');
header('Content-Disposition: attachment; filename=data.csv');
$output = fopen('php://output', 'w');
fputcsv($output, $name);
?>

What am I doing wrong?
