wp_set_comment_cookies() │ WP 3.4.0

Sets the cookies (name, email, url) that are used to identify an unauthenticated user when commenting.

Hooks from the function

Returns

null. Nothing (null).

Usage

wp_set_comment_cookies( $comment, $user, $cookies_consent );
$comment(WP_Comment) (required)
Comment object.
$user(WP_User) (required)
Comment author's user object. The function will do nothing if the user exists — so that the cookies are saved only to unauthenticated commenters.
$cookies_consent(true/false)
Comment author's consent to store cookies.
Default: true

Examples

#1 Setup commenter cookies

By default, cookies are set up using following action in wp-comments-post.php file:

do_action( 'set_comment_cookies', $comment, $user );

But in this example we will set up them separately. For example, when the comment is posted (added) not through the wp-comments-post.php file:

$user    = wp_get_current_user();
$comment = get_comment( $id = 255 );

wp_set_comment_cookies( $comment, $user );

Changelog

Since 3.4.0 Introduced.
Since 4.9.6 The $cookies_consent parameter was added.
