I have problem with seting and reading cookie on wordpress site.
Here is what I'm doing:
1.Sending over js id to php
ajax.js
jQuery.post("/wp-content/themes/mytheme/ajax.php", {post_id: post_id}, function(data){
});
ajax.php
setcookie('myids', $_COOKIE['myids'].$_POST['post_id'], time()+3600*24*100, '/');
2.When I read that cookie ( echo $_COOKIE['myids']; )in /wp-content/themes/mytheme/index.php
I get value which I set and that is ok but when i try to read that cookie in /wp-content/themes/mytheme/ajax.php I am not getting cookie.
What I am doing wrong?
