我已经为我的客户建立了一个巨大的网络多站点，每月接收 1000 个新用户，并且已经有 5 个克隆网络站点，并且还在不断增加。它有一个静态主页，主题我的登录插件在定制的 Divi 子节点上运行主题。
在自定义的登录页面上，登录本身工作正常，下面有两个“注册”和“丢失密码”的“操作链接”。我有两个外部自定义页面可以链接到这两个链接。
因此，我编辑子主题的functions.php 文件，该文件中已经有一些工作过滤器，用于处理外部身份验证、视频（popcorn.js）、动态版权以及从管理栏中隐藏Wordpress 徽标。
我想将默认的注册/丢失密码“操作链接”更改为不同的 URL，更改其链接标题并修改错误页面，以便“丢失密码？”链接将指向与丢失密码“操作链接”相同的 URL。
以下是上述所需更改之前的 Functions.php 文件：
<?php
/*
PHP script content in functions.php of Child Theme in Wordpress Network
Multisite.
Functions to add new externally authenticated users as wordpress users
at subscriber level via email field using HTTP POST.
Usernames expected in the format: [email protected] /cdn-cgi/l/email-protection or [email protected] /cdn-cgi/l/email-protection
(also all variations of .com.au, .co.nz, etc.)
New Wordpress Network MultiSite Subfolders are assigned to their own groups of users.
On login their WordPress profile is automatically created in the MultiSite
Subfolder for that user; based on the DOMAIN portion of username/email.
Accordingly, Wordpress Network Subfolder names match the DOMAIN exactly.
eg: "http://wpsite.com/DOMAIN/Home" is the landing page for the user:
"[email protected] /cdn-cgi/l/email-protection" or "[email protected] /cdn-cgi/l/email-protection" and so on.
The Logic flow is below annotated and step by step along with the script:
1.Do the external check: The external login must be successful and the return
value must be validated with a "200" response from the external auth' server.
If response is anything else give an error.
2.Do another check to see if they exist in the WP DB, if not; create them
first (EVERY user in WordPress has a unique ID, so using this ID to identify a user in this script.)
If the ID is found, our user is automatically logged in
and lands on their home page.
If the user does NOT exist, the user should be created automatically on the
relevant subfolder site (see notes ablove)
