Question

对于我的学校，我必须制作一个脚本，我可以在其中添加，编辑和删除数据库中的记录！

现在我忙于删除部分，但它不会工作..我尝试使用带有用户ID号的复选框删除记录。

它一直说工作成功但从不删除任何东西...... - ， -

// // delete.php

<?php include "connect.php" ?>
<!DOCTYPE html>
<html>
<head>
    <title>Verweider gebruiker</title>
</head>
<body>
<?php
    $q="SELECT * FROM naw";
    $result = mysqli_query($server,$q) or die(mysqli_error($server));

    while ($r = mysqli_fetch_array($result)) {
?>
    <form action="delete_user.php" method="POST">
        <table>
            <tr>
            <td>
                <td>
                    <input type="checkbox" name="id[]" value="<?php echo $r[0] ?>" />
                </td>
                <td>
                    <?php echo $r[1] ?>
                </td>

// // delete_user.php

<?php

error_reporting(E_ALL);

    $chk = $_POST['id'];
    $chkcount = count($chk);

    if(!isset($chk))
    {
        ?>
        <script>
        alert('Je moet minimaal 1 bericht selecteren');
        window.location.href = 'delete.php';
        </script>
        <?php
    }
    else
    {
        for($i=0; $i<$chkcount; $i++)
        {

        $del = $chk[$i];
        $q="DELETE FROM naw WHERE id=".$del;
    }

        if($q)
        {
            ?>
// this alert i get everytime, but it didn't delete anything... i don't get it :(
        <script>
                alert('De gebruiker is verwijderd');
                window.location.href='gebruiker.php';
            </script>
            <?php

            ?>
            <script>
                alert('Er ging iets fout, probeer het opnieuw');
                window.location.href='delete.php';
            </script>
            <?php
