Think I have two PHP projects on the server. Can the form be submitted to another project?

I have two PHP projects on my server, one is a company website based on the TP framework, and the other is also a PHP website, but it is a purchased ready-made video live broadcast website.

I pointed the main domain name to the company website, www.xxx.com, and then built a secondary domain name on Alibaba Cloud, pointing to the live video website, zb.xxx.com.

Now, the requirement is that after registering and logging in on any website, you can log in on another website. What I want to ask experts is, can I submit the registration form of any website, not only to the current In the project database, can it be submitted to the database of another project? How to write form?

I can’t find it on Baidu, so I can only come here to ask an expert for advice, thank you

Form cannot be done, you can manually send the request to another project on the corresponding processing page. BTW, if you don't mind the trouble, you can use oauth. This kind of multi-site user synchronization oauth is a better solution.

After submitting to this project, you can remotely link the database to write the data to another project. There is no need to submit the form twice

I have been in this situation before. But my two projects share the same database.
Or you can set the scope of the session.
www.xxx.com and zb.xxx.com Take a look at their scopes. They should all be xxx.com
Then add the following code to your main entry file (before the session is opened)
ini_set('session.cookie_path', '/');
ini_set('session.cookie_domain', '.xxx .com');
This is how I solved it.

session sharing mechanism

Cross-domain is impossible!

Use ajax, and then use CORS for cross-domain, submit the form to the current project, and use ajax to request another project.

Inquire about single sign-on solutions.

The temporary solution is that when you put project A into the database, you also forget to put a copy of project B into the database. The recommended solution is to use a single sign-on system (SSO) and verify the login from SSO every time you log in

Shared user database should be possible
