PHP重定向Cookie问题

Question

Hi I want all my new / 1st users to my site to get redirected to a different page.

Its a wordpress page and in the index.php file I have this code right on top

<?php
if ($_COOKIE['iwashere'] != "yes") { 
setcookie("iwashere", "yes", time()+20000);  
header("Location: http://howtobuygoldoffshore.com/sitemap"); 
exit;
}
?>

Now the issue is when I clear all cache and cookies from my browser and access this page it only goes to howtobuygoldoffshore.com instead of going to howtobuygoldoffshore.com/sitemap.

But now if I access it with a www.howtobuygoldoffshore.com then it goes to the correct landing page.(the www. is making some different I suppose)

What could be the issue? Is the code correct which I am writing and inserting in the index.php file or is there some issue with the re direction?

Answer 1

Your cookie isn't for all the subdomains on your site.

setcookie ( string $name [, string $value [, int $expire = 0 [, string $path [, string $domain [, bool $secure = false [, bool $httponly = false ]]]]]] )

See the parameter $domain. Try to save your cookie as $domain = howtobuygoldoffshore.com instead:

setcookie("iwashere", "yes", time()+20000, '/', 'howtobuygoldoffshore.com');

This will make your cookie work on both http://howtobuygoldoffshore.com and http://www.howtobuygoldoffshore.com .
