Redirect to homepage from splash page magento - php

Question

I am trying to redirect to my homepage from a splash (age verification) page, and it just keeps popping up the same age verification page.
I have the ageVerify.php script in the root folder and I have the other script at the top of my template file page. I just need to find the correct file structure format to redirect too after someone hits "yes i'm 18"
The code below doesn't work when added to the top of my column1.phtml file - it just keeps going back and recalling the verify.php script. Any ideas would be very helpful!
<?php
function verified()
{
$redirect_url='http://www.johnsoncreeksmokejuice.com.vhost.zerolag.com/verify.php';
$expires=-1;
session_start();
$validated=false;
if (!empty($_COOKIE["verified"])) {
$validated=true;
}
if (!$validated && isset($_SESSION['verified'])) {
$validated=true;
}
if (is_numeric($expires) && $expires==-1 && !isset($_SESSION['verified'])) {
$validated=false;
}
if ($validated) {
return;
}
else {
$redirect_url=$redirect_url."?return=index.php&x=".$expires;
Header('Location: '.$redirect_url);
exit(0);
}
}
verified();
?>

Answer 1

If $_SESSION is not set always will evaluate this
if (is_numeric($expires) && $expires==-1 && !isset($_SESSION['verified'])) {
$validated=false;
}
Just fix it and should work.
Assuming that everything else is fine, I would replace
if (!empty($_COOKIE["verified"])) {
$validated=true;
}
if (!$validated && isset($_SESSION['verified'])) {
$validated=true;
}
if (is_numeric($expires) && $expires==-1 && !isset($_SESSION['verified'])) {
$validated=false;
}
By:
if ( (isset($_COOKIE["verified"] && !empty($_COOKIE["verified"])) OR isset($_SESSION['verified']) ) {
$validated=true;
}
So, if user has a non-empty "verified" cookie or a "verified" session set, it assumes he is validated.

Chose to use a javascript alternative. Worked out much easier for me:
function writeCookie(key,value,days) {
if (days) {
var date = new Date();
date.setTime(date.getTime()+(days*24*60*60*1000));
var expires = "; expires="+date.toGMTString();
}
else var expires = "";
document.cookie = key+"="+value+expires+"; path=/";
}
function readCookie(key) {
var nameEQ = key + "=";
var ca = document.cookie.split(';');
for(var i=0;i < ca.length;i++) {
var c = ca[i];
while (c.charAt(0)==' ') c = c.substring(1,c.length);
if (c.indexOf(nameEQ) == 0) return c.substring(nameEQ.length,c.length);
}
return null;
}
