Multiple Homepages

This can be done using the WordPress hook template_redirect and the PHP function setcookie().

Place this code in your functions.php file or use the Code Snippets plugin. Replace secondary-homepage with the slug of the page you create for subsequent visits. You can also replace WEEK_IN_SECONDS with any of these:

• MINUTE_IN_SECONDS
• HOUR_IN_SECONDS
• DAY_IN_SECONDS
• MONTH_IN_SECONDS
• YEAR_IN_SECONDS

add_action('template_redirect', 'wpsf_multiple_homepages');
function wpsf_multiple_homepages()
{
  // Visitor arrives at front page
  if (is_front_page()) {

    // It's their first visit
    if (!isset($_COOKIE['wpsf-homepage'])) {

      // Remember that they've visited
      setcookie('wpsf-homepage', 'visited', time() + WEEK_IN_SECONDS, COOKIEPATH, COOKIE_DOMAIN, true);
      return;
    }

    // On subsequent visits...
    if (isset($_COOKIE['wpsf-homepage'])) {

      // Send visitor to another page
      wp_safe_redirect(home_url('secondary-homepage'));
      exit;
    }
  }
}

@rickymccallum87 Thank you for the assistance. However, for some reason, the code is not working. Upon entering the homepage, the browser doesnt seem to see the cookie (I checked through the console, but did not find a cookie with that name there). I am working on a local setup, if thats relevant somehow.
Another question: Assuming I get the code to work, how can I get the pages to alternate? So I enter the website for the first time, loading page A. COokie is created. On the second visit, it checks for the cookie and redirects me to Homepage B. Is it possible to delete the cookie with the redirect, thus ensuring that on a visitor’s third visit, they will be taken back to page A? Making the user effectively cycle through both homepages based on the one last visited. That is my intention all along; apologies that that was not clear in my original question.

The final parameter in the setcookie() function is true for secure HTTPS connections. Switching that to false temporarily will probably get it working for your local install.

Alternating homepages is a bit more complicated. I’ve set this up how you described: setting the cookie on the first visit and expiring it on the second.

add_action('template_redirect', 'wpsf_alternating_homepage');
function wpsf_alternating_homepage()
{
  // Visitor arrives at front page
  if (is_front_page()) {

    // It's their first visit (or an odd-numbered visit)
    if (!isset($_COOKIE['wpsf-homepage'])) {

      // Remember that they've visited
      setcookie('wpsf-homepage', 'visited', time() + WEEK_IN_SECONDS, SITECOOKIEPATH, COOKIE_DOMAIN, false);
      return;
    }

    // It's their second visit (or an even-numbered visit)
    if (isset($_COOKIE['wpsf-homepage'])) {

      // Forget visitor by expiring the cookie
      setcookie('wpsf-homepage', 'visited', 1, SITECOOKIEPATH, COOKIE_DOMAIN, false);

      // Send visitor to the other front page
      wp_safe_redirect(home_url('secondary-homepage'));
      exit;
    }
  }
}

@rickymccallum87 Many thanks for your time; struggled with this for almost a week now, so it is much appreciated. All is working fine and dandy now.
