我有一个带有复选框的表格和一个允许用户被“批准”的按钮，数据库中的一个简单的 1 表示他们已被批准。我想先检查一下用户是否已经被批准，这样我就可以显示一条错误消息。然而，在这段代码中最终发生的是，由于某种原因，代码执行底层 sql，但按原样显示错误消息，或者!$check总是显示成功消息。我尝试了不同的变体，但我感觉问题出在我的 $check sql 逻辑上。我只是似乎看不到它。

if ($_POST['doApprove'] == 'Approve') {
    if (!empty($_POST['u'])) {
        foreach ($_POST['u'] as $uid) {
            $id = filter($uid);
            $username[] = get_user_name_from_id($id);
            $check = Nemesis::select("approved", "users", "id = '{$id}' AND approved <> '1'");  // issue?
            $set_approve = Nemesis::update("users", "approved = '1'", "id = '{$id}'");
            if ($check) { // issue?
                $fail[] = $username;
            } elseif (!$set_approve) {
                $fail[] = $username;
            } else {
                $pass[] = $username;
                $user_details = Nemesis::select("*", "users", "id = '{$id}'");
                $ud_row = $user_details->fetch_assoc();
                authMail('register', $ud_row['user_email'], $ud_row['pwd'], $ud_row['user_name'], NULL, 'admin');
            }
        }
    }
    $msg = new Messages();
    if (!empty($pass)) {
        $passed = implode(', ', $pass);
        $message = "Approved: {$passed}";
        $msg->add('s', $message);
    }
    if(!empty($fail)){
        $failure = implode(', ', $fail);
        $message = "Could not approve {$failure}";
        $msg->add('e', $message);
    }
    redirect('users.php');
}
