Question

任何人都可以帮我吗？我想在我的数据库中编辑一条记录。一切正常。如果我点击按钮，它会保存记录。但它并没有将我重新引导回transparente.php！我刚得到一个白色网站...... 请帮助我！

<?php

define('INCLUDE_CHECK',true);

require 'connect.php';
require 'functions.php';

session_name('tzLogin');

session_set_cookie_params(7*24*60*60);

session_start();

if(isset($_GET['logoff']))
{
    $_SESSION = array();
    session_destroy();

    header("Location: demo.php");
    exit;
}

 function renderForm($id, $Name, $Wer, $Erhalten, $Digital, $Betrag, $Bezahlt, $Anmerkung, $error)
