Javascript Alert Box (Stay on same page)?

Question

I'm creating a download page in PHP, which will display an alert box in Javascript IF the download file does not exist (when the user clicks a button for the corresponding product).

The PROBLEM is, once the user hits OK on the alert box, it navigates away from the current page (that lists the downloads). I want it to STAY on the same page with the SAME content to be displayed.

Full code:

<?php
$product = $_GET["p"];
$ChangeFileName = "";

if ($product == 'Product1')
{
    $realFileName = "OriginalFileName.exe";
    $ChangeFileName = "NewFileNameHere.exe";
}
elseif ($product == 'Product2')
{
    $realFileName = "OriginalFileName.exe";
    $ChangeFileName = "NewFileNameHere.exe";
}
else
{
    echo '<script type="text/javascript">
    alert("Sorry, there is no download available for this product! Please contact support.");
    </script>';
    exit;
}

$file = "downloads/".$realFileName;
$fp = fopen($file, 'rb');

header("Content-Type: application/octet-stream");
header("Content-Disposition: attachment; filename=$ChangeFileName");
header("Content-Length: " . filesize($file));
fpassthru($fp);
?>
exit;

I've tried 'return false;' as well, but it still navigates away from the page. — James, May 31 '15 at 05:54

You can open download page a new window and ;

echo '<script type="text/javascript">
alert("Sorry, there is no download available for this product! Please contact support.");
window.close();
</script>';
exit;

if the download file does not exist alert and close download page after back first page.

Or Ajax download: download file using an ajax request
