AUTHOR_EMAIL FILTER自定义评论作者的EMAIL

吾爱互联

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：
</div><p>apply_filters ( &lsquo;author_email&rsquo;, string $author_email, int $comment_ID )</p>
<p><br />
在wp-<a href="/tags.php/include/" target="_blank">include</a>s/comment-template.php的comment_author_email函数中用到了author_email的filter。</p>
<p>function comment_author_email( $comment_ID = 0 ) {<br />
&nbsp;&nbsp;&nbsp; $author_email = get_comment_author_email( $comment_ID );<br />
&nbsp;<br />
&nbsp;&nbsp;&nbsp; /**<br />
&nbsp;&nbsp;&nbsp;&nbsp; * Filter the comment author's email for display.<br />
&nbsp;&nbsp;&nbsp;&nbsp; *<br />
&nbsp;&nbsp;&nbsp;&nbsp; * @since 1.2.0<br />
&nbsp;&nbsp;&nbsp;&nbsp; * @since 4.1.0 The `$comment_ID` parameter was added.<br />
&nbsp;&nbsp;&nbsp;&nbsp; *<br />
&nbsp;&nbsp;&nbsp;&nbsp; * @param string $author_email The comment author's email address.<br />
&nbsp;&nbsp;&nbsp;&nbsp; * @param int&nbsp;&nbsp;&nbsp; $comment_ID&nbsp;&nbsp; The comment ID.<br />
&nbsp;&nbsp;&nbsp;&nbsp; */<br />
&nbsp;&nbsp;&nbsp; echo apply_filters( 'author_email', $author_email, $comment_ID );<br />
}
