从…起this question:

您可以使用几个过滤器来完成此操作：

<?php

function wpse_112719_pre_post_link( $permalink, $post, $leavename ) {
    if ( strpos( $permalink, \'%author%\' ) !== false ) {
        $authordata = get_userdata( $post->post_author );
        $author_id = $authordata->ID;
        $permalink = str_replace( \'%author%\', $author_id, $permalink );
    }

    return $permalink;
}

add_filter( \'pre_post_link\', \'wpse_112719_pre_post_link\', 10, 3 );

function wpse_112730_add_rewrite_rules() {
  add_rewrite_rule(
      "([0-9]+)/(.*)",
      \'index.php?name=$matches[2]\',
      \'top\'
  );
}

add_action( \'init\', \'wpse_112730_add_rewrite_rules\' );

现在，转到设置→ Permalinks并将Permalinks设置为/%author%/%postname%/. 保存您的更改，您的链接应该会相应地工作。如果您有任何问题，请告诉我！
