My requirement is to add couple of custom fields in the add/edit a site forms without touching the WordPress core. I tried to copy the site-new.php from /wp-admin/network and paste it into my custom plugin but it fails due to many dependencies. I dont think so it is good exercise to copy and paste the whole network folder inside the plugin.
I also tried to callout this hook but instead of override, it just show me the fields underneath of the form. I guess I need to add hook when users submit the form. but couldn\'t find the hook that I need to callout to save additional fields data in DB.
add_action(\'network_site_new_form\', array($this, \'add_extra_new_site_fields\'));
Added this function
function add_extra_new_site_fields()
{
?>
<form method="post" action="<?php echo network_admin_url( \'site-new.php?action=add-site\' ); ?>" novalidate="novalidate">
<?php wp_nonce_field( \'add-blog\', \'_wpnonce_add-blog\' ); ?>
<table class="form-table" role="presentation">

将标记添加到“添加新网站”表单中可以如下所示将HTML标记添加到该表单中：
add_action(
\'network_site_new_form\',
function() {
?>
<p>Hello World</p>
<?php
}
);
向编辑网站表单添加标记
No. This cannot be done via PHP.
对于站点编辑信息屏幕，不存在执行此操作的挂钩。
However, 您可以通过network_edit_site_nav_links 过滤器，允许您创建自定义网络管理页面，该页面将站点ID作为URL参数传递。但是，您需要通过重新创建选项卡network_edit_site_nav 并保存和展示自己。
创建站点时，如何保存额外的输入
有点
没有专用的钩子来保存这些字段。添加HTML的钩子不是现有字段所在表的一部分，它们不会对齐。如果没有用户使用所选的管理员电子邮件，则在创建用户之前和之后都有一个钩子，但它发生在创建站点之前。您可以使用wp_insert_site 钩子在网站创建后在网站上执行工作，但是您应该检查您的字段是否存在，它甚至可能不是web请求，也可能不是网络管理员：
do_action( \'wp_insert_site\', $new_site );
也要小心，当这种情况发生时，WP将处于安装模式，通常可用的东西可能不可用。这些事情是什么还不清楚。
我的建议是不要这样做。自定义网络管理区域的最佳方法是完全删除它们，然后通过管理菜单API使用全新的网络管理页面重新实现它们。
network admin API不是用于扩展的，network admin的构建也不是为了按照您想要的方式进行扩展。通常开发起来微不足道的东西应该被视为顶级超硬产品。
此外，即使您可以存储这些值，也没有用于查看它们的UI，并且无法扩展现有UI。你必须从头开始构建它。
