我正在尝试此代码codex wordpress site

function custom_rewrite_basic() {
    add_rewrite_rule(\'^leaf/([0-9]+)/?\', \'index.php?page_id=$matches[1]\', \'top\');
}
add_action(\'init\', \'custom_rewrite_basic\');

必须如何通过。必须为上述代码配置htaccess文件才能使其有意义？如果我把基本的wordpress.htaccess 配置文件，然后我被重定向到同一页。

<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /
RewriteRule ^index\\.php$ - [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [L]
</IfModule>
