Question

经过大量的搜索和错误搜索后，我难倒了。重定向不允许我访问实际站点的代码有什么问题？我无法获得年龄输入来指引我到主站点或index.php。无论输入什么日期，如果答案错误，重定向到用户将去的地方 - 在这种情况下，youtube。

这是我在index.php本地工作的内容：

<?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}");

?>

该部分很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..很多变化）：

<?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基金会中使用它。这是几个脚本拼凑在一起，至少可以像它一样工作。如上所述，缺少最后一步 - 使用cookie进行正确的重定向，这样用户只能获得一次年龄验证，无论输入页面是什么，它都会出现。这是一个vaping网站，他们要求年龄验证。

我在本地使用WAMP作为开发依据。

Answer 1

尝试更改您的PHP代码：

if (!isset($_COOKIE['Visited'])) {

为：

if (!isset($_COOKIE['verified'])) {

或：

if($_SESSION['verified'] != "yes"){

Answer 2

K我发现了问题，似乎$ _COOKIE [“Visited”]无法使用，它必须像某个系统的标准，所以你必须将其更改为其他内容：visitherebefore。以下是我如何使用它：

<?php

@session_start();
$showform = false;

    //created my own date function
function age($dob){ 
    $date1 = new DateTime(date("Y-m-d", strtotime($dob)));
    $date2 = new DateTime(date("Y-m-d"));
    $interval = $date1->diff($date2);
    return $interval->y;
}

    //if a form is submitted do the following
if(array_key_exists("submit", $_POST)){
    $m = $_POST["month"];
    $d = $_POST["day"];
    $y = $_POST["year"];

    $age = age($y."-".$m."-".$d);
    //check age here
    if($age > 17){
                    //set cookie here and redirect here if you want
        setcookie('visitedherebefore', 'Cookies seems legit', time() + 3600);
        die("Old enough... nuff said...");
    }else{
                    //redirect here as well
        die("Too Young Sorry! you will now be redirected");
    }
}

    //check if user has been here before, redirect here as well if you want
if (isset($_COOKIE['visitedherebefore'])) {
  print "welcome back!";
  die();
}

＆GT;

<form action="index.php" method="post">
    <input type="text" tabindex="1" onkeypress="return isNumberKey(event)" onkeyup="jumpField(this,this.value)" id="month" name="month" maxlength="2" size="2" required="required" value="MM" onfocus="value=''" />
    <input type="text" tabindex="2" onkeypress="return isNumberKey(event)" onkeyup="jumpField(this,this.value)" id="day" name="day" maxlength="2" size="2" required="required" value="DD" onfocus="value=''"  />
    <input type="text" tabindex="3" onkeypress="return isNumberKey(event)" onkeyup="jumpField(this,this.value)" id="year" name="year" maxlength="4" size="4" required="required" value="YYYY" onfocus="value=''" />

    <input type="submit" value="Enter Superior Vaping" id="submit" name="submit" />
</form>

Answer 3

令我惊讶的是，我做了以下工作。我不认为我在编码方面更好，只是更勤奋，不愿意放弃。这是我的决心：记住，我正在做一个Joomla！平台，因此index.php是站点中每个页面的基础页面。因此，要开始验证，无论访问者使用哪个页面进入，初始代码都必须进入模板/？template-name？/index.php

<?php   
    if(!isset($_COOKIE['legal'])) {         
    header("Location: verifyage.php");   
    }

    if($_COOKIE['legal'] == "no")
                    {
                    header("Location: http://www.google.com/");  
                    }

＆GT;

然后，在verifyage.php中，我使用了以下内容：

<?php
    /*if the cookie already exists from a previous remember me button click then skip this page*/                   
    error_reporting(E_ALL ^ E_NOTICE); //I don't know if that's right, but it works to keep the 1 error off the page - not by fixing, but hiding the error of legal not defined

    if($_COOKIE['legal'] == "yes")
                    {
                    header("Location: index.php");   
                    }                       

    if (isset($_POST['checkage'])) 
    {
    $day = '';
    $month = '';
    $year = '';
    $minage = '18';


    if(isset($_POST['day']))
            {
            $day = $_POST['day'];
            }

    if(isset($_POST['month']))
            {
            $month = $_POST['month'];
            }

    if(isset($_POST['year']))
            {
            $year = $_POST['year'];
            }



    $birthstamp = mktime(0, 0, 0, $month, $day, $year);
    $diff = time() - $birthstamp;
    $age_years = floor($diff / 31556926);

    if($age_years >= $minage) 
            {
            if($rembox=="yes")
                    {
                    setcookie('legal', 'yes', time() + 31556926);
                    }
                    else{
                    setcookie('legal', 'yes', 0);

                    }
                    $url = 'index.php';
            } 
    else 
            {
            setcookie('legal', 'no', 0);
            $url = 'http://www.google.com/';
            }

    header('Location: '.$url.'');
    }

＆GT;

在同一页面中，我添加了以下HTML，它提供了灯箱效果，并为输入创建了字段：

<html>
<head>
<title>Age Verification</title>
<script language=Javascript>
  <!--
  function isNumberKey(evt)

     var charCode = (evt.which) ? evt.which : event.keyCode

        return false;

     return true;

当我在这里发布代码时，我可以看到'可能'会有一些不必要的代码或行。但我可以说它工作得很好，我已经将代码实现到了实时网站。如果有人认为有一些“不要那样”或“我不会......”，请随意加入，因为我并不是自称是专家。一个月前，我只对我所寻求的东西发表决心。我很确定可以删除Onload。我感谢Relentless提供的所有帮助。我希望发布这个对他人有价值。如果您有疑问或想告诉我，我做了一些不可原谅的事情，我愿意提供所有信息。感谢。
