要创建基本插件，请在中添加目录wp-content/plugin, 然后用required header, 就这样。

现在，下面是如何使用该操作：

add_action( \'wpmu_new_blog\', \'user16975_customize_blog\', 10, 6);
function user16975_customize_blog($blog_id, $user_id, $domain, $path, $site_id, $meta ){
    // do not forget to select the correct blog (we are in mutisite admin)
    switch_to_blog($blog_id);

    // You can retrieve the register information in $_POST var, depending on your registration form

    // change the blog name
    update_option(\'blogname\', \'M&F Lastname\');

    // change the blog address
    $newurl = esc_url( \'http://\' . $domain . \'m&f-lastname\' );
    update_option( \'siteurl\', $newurl );
    update_option( \'home\', $newurl );

    // rename the default article
    wp_update_post(array(
        \'ID\' => 1,
        \'post_title\' => \'Long live the newlyweds!\',
        \'post_name\' => \'long-live-the-newlyweds\'
    ));

    restore_current_blog();
}
