经过大量搜索和反复试验后，我被难住了。 重定向不允许我访问实际站点的代码有什么问题？我无法获取年龄输入以将我定向到主站点或 index.php。无论输入什么日期，如果答案错误，用户都会重定向到用户要去的地方 - 在这种情况下，youtube。
这是我在本地工作的 index.php 中的内容:
<?php
@session_start();
$url = 'http://localhost/J2.5/index.php';
if (!isset($_COOKIE['Visited'])) {
$_COOKIE['Visited'] = 1;
$url = 'http://localhost/J2.5/ageverificationone.php';
}
header("Location: {$url}");
?>
这部分非常适合弹出年龄验证脚本所在的实际页面 - ageverificationone.php(可以是任何名称..尝试了很多变体):
<?php
session_start();
if($_SERVER['REQUEST_METHOD']=='POST')
{
if(isset($_POST['YES']))
{
$redirect=isset($_GET['return'])?urldecode($_GET['return']):'./';
$expire=isset($_GET['x']) && is_numeric($_GET['x'])?intval($_GET['x']):-1;
if($expire==-1)
{
$_SESSION['verified']="yes";
header("location: ".$redirect);
exit(0);
}
if($expire==0)
{
setcookie("verified", "yes",mktime(0,0,0,01,01,date("Y")+30));
$_SESSION['verified']="yes";
header("location: ".$redirect);
exit(0);
}
setcookie("verified", "yes",(time()+$expire));
$_SESSION['verified']="yes";
header("location: http://www.superiorvaping.com/");
exit(0);
}else{
header("location: http://www.youtube.com/watch?v=gppbrYIcR80");
exit(0);
}
}
?>

我在 Joomla 基础中使用它。这是几个脚本组合在一起至少可以正常工作。 如前所述，缺少最后一步 - 使用 cookie 获得正确的重定向，以便用户仅获得一次年龄验证，并且无论输入页面如何，它都会出现。 这是针对电子烟网站的，他们要求进行年龄验证。
我正在使用 WAMP 作为开发基础在本地执行此操作。
谢谢 托马斯
最佳答案
尝试更改您的 php 代码:
if (!isset($_COOKIE['Visited'])) {
到:
if (!isset($_COOKIE['verified'])) {
或:
if($_SESSION['verified'] != "yes"){
