wordpress4.1新增了一个钩子:author_email,可以利用这个filter显示自定义评论作者的email,形式如下:
apply_filters ( ‘author_email’, string $author_email, int $comment_ID )
在wp-includes/comment-template.php的comment_author_email函数中用到了author_email的filter.
- function comment_author_email( $comment_ID = 0 ) {
- $author_email = get_comment_author_email( $comment_ID );
- /**
- * Filter the comment author's email for display.
- *
- * @since 1.2.0
- * @since 4.1.0 The `$comment_ID` parameter was added.
- * //Vevb.com
- * @param string $author_email The comment author's email address.
- * @param int $comment_ID The comment ID.
- */
- echo apply_filters( 'author_email', $author_email, $comment_ID );
- }
