如何在wordpress中设置cookie？

Question

I want to set cookie in wprdpress but its not working.This is my code

add_action('init', 'set_new_cookie');
    function set_new_cookie() {
        setcookie('cart_item','some value', time() + (86400 * 30), "/");
    }

but this is not working. Actually init hook is not working.I am trying to do ajax request here(page visitors are not logged in).

Answer 1

setcookie('cart_item',$carts,time() + (86400*30),'/');

Its working fine for me. / at the last is to set cookie for whole site. Remove / to set cookie for particulat directory only.
