WordPress Redirect based on the prescence of a cookie

0 Views

I have a tricky situation….
I’d like to check for a cookie. If it doesn’t exist then then redirect to an internal wordpress page, and set a cookie. And then carry on browsing the site. But i get stuck in a loop if the url doesn’t exist. This is what i have so far…any help would be great. 

function cookiebasedredirect() {

    // WHEN YOU HAVE FOUND YOUR COOKIE
    if ( !isset($_COOKIE["sevisitor"])) {

        setcookie('sevisitor', 1, time()+1209600, "/", "http://localhost/child/", false);       

        // GRABS THE CURRENT PAGE NAME - THIS IS ALSO KNOWS AS THE PAGE/POST SLUG
        $pagename = get_query_var('pagename');

        // PAGE CHECK SO THAT YOU ARE NOT IN AN INFINITE LOOP
        // IN THIS SAMPLE MEDIA-GALLERIES IS THE PAGE YOU WANT TO BE 
        //  REDIRECTED TO IF A COOKIE IS NOT SET, BUT ONCE YOU GET THERE
        // MAKE SURE WORDPRESS DOESN'T EXECUTE THE REDIRECT
        if( $pagename != "about-myself") {          
            wp_redirect( get_site_url().'/about-myself' ); exit;

        } else {


        }


    } else {

    }}
add_action("template_redirect", "cookiebasedredirect");

  1. why not use the init action hook:

    function has_my_cookie()
{
    if (!is_admin()){
        //Check to see if our cookie is set if not redirect to your desired page and set the cookie
        if ( !isset($_COOKIE["sevisitor"])) {
            //setcookie
            setcookie('sevisitor', 1, time()+1209600, "/", "http://localhost/child/", false);
             //Redirect 
            wp_redirect( get_site_url().'/about-myself' ); exit;
        }
    }
}
add_action('init', 'has_my_cookie');

  2. My final solution…

    function cookie_redirect() {

    // THE PAGE SLUG, YOU WANT TO BE REDIRECTED TO, WHEN THERE IS NO COOKIE
    $pageslug = "about-myself";

    // THE COOKIE NAME
    $cookie_name = "thecookiemonster";

    // CHECK IF YOUR COOKIE IS SET
    if (!isset($_COOKIE[$cookie_name])) {

       // SINCE THERE IS NO COOKIE, THEN SET IT
       setcookie( $cookie_name, 1, time()+1209600, SITECOOKIEPATH, COOKIE_DOMAIN, false, true);

        // GRABS THE CURRENT PAGE NAME - THIS IS ALSO KNOWN AS THE PAGE/POST SLUG
        $pagename = get_query_var('pagename');

        // MAKE SURE YOU ARE NOT AT THE PAGE YOU WANT TO BE DIRECTED TO, PREVENTS LOOP
        if( $pagename != $pageslug) {
            // REDIRECT US
            wp_redirect( get_site_url() . '/' . $pageslug ); exit;
        } else {

        }

    } else {


    }
}
add_action( 'init', 'cookie_redirect');
