get_comment_author_email_link() WP 2.7.0

Return the html email link to the author of the current comment.

Care should be taken to protect the email address and assure that email harvesters do not capture your commenter's email address. Most assume that their email address will not appear in raw form on the site. Doing so will enable anyone, including those that people don't want to get the email address and use it for their own means good and bad.

  • Since 4.6.0 Added the $comment parameter.
