I have a basic function running with the after_setup_theme hook. I need the function to access the current blog post’s id but it’s always false using get_the_ID. How can I access the current post’s id in this function? Code included in the description

Hi

I have a function that needs to store the current blog’s id in the cookie.

The function I have is this inside **functions.php**:

function set_post_id_in_cookie() {
if (!is_single(‘post’)) return

$post_id = (string) get_the_ID();

return setcookie(‘post_id’, $post_id, time()+86400*30*12, ‘/’);
}

add_action( ‘after_setup_theme’, ‘set_post_id_in_cookie’ );

I have 2 issues:

1. `is_single(‘post’)` always returns false on single posts/blogs. Why?
2. `get_the_ID()` returns `false`. Why?

Any help is appreciated. Thanks
