用户在我们的网站上输入唯一代码即可下载特定文件（链接到该代码）。一切正常，但是，我希望在提交后重新设置表格。
这是代码。
if($_POST['submit']) {
include_once('php/connect.php');
if(!isset($_POST['akkoord'])){
?>
<script>alert ('U moet zich akkoord verklaren met de licentieovereenkomt om te scores en partijen te kunnen downloaden en te mogen gebruiken!');</script>
<?php
}else{
$uniekecode = mysqli_real_escape_string($dbc, $_POST['code']);
$q = "SELECT * FROM downloadleerkracht where code = '$uniekecode'";
$run = mysqli_query ($dbc, $q);
$row = mysqli_fetch_assoc($run);
$num = mysqli_num_rows($run);
$filename=$row['file'];
if($num == 1){
?>
<script>
$('#downloadform')[0].reset();
</script>
<?php
header('Content-type: application/octet-stream');
header('Content-Disposition: attachment; filename="'.$filename.'"');
readfile ("bestanden/$filename");
$update = "UPDATE downloadleerkracht SET gedownload='1', akkoord='1', date=NOW() WHERE code='$uniekecode'";
$runupdate = mysqli_query($dbc, $update);
exit();
}else{
?>
<script>alert ('Dit is geen geldige code!');</script>
<?php
}
}}
?>
强制进行下载，但是尽管
，但用户输入的代码仍保留在输入字段中<script>
$('#downloadform')[0].reset();
</script>
