I want to write referral URL to cookie and use it at some point to echo that referral URL on my website. What is the best way to achieve this?

Thank you

You can do this as we do in PHP. You can set cookie following way.

setcookie( 'cookie-name', 'cookie-value', 'cookie-expiration-time', 'cookie-path', 'cookie-domain', false );

For referral url, I made following code that you can use to set a cookie with name my-referral-cookie and time() + 3600 (1 hour from current time) is expiration time for cookie.

setcookie( 'my-referral-cookie', $_SERVER['HTTP_REFERER'], time() + 3600, COOKIEPATH, COOKIE_DOMAIN, false );

You can get the value of cookie like this.

echo $_COOKIE['my-referral-cookie'];

That's it.
