Create Login and Register Page in Custom Portal

[AlhussainiM]

Hello every body , 
I have a question about login and register page in the portal , 
My scenario is :  I am working on application to automate issue the certificates to citizens(birth .. etc)  I have two tables ,
1- called user (core table),
2- citizen (custom) table 
I suppose in the citizen table I have all citizens data in my country , but not all citizens are users in my application. 
So I want in my register page in the portal write National ID of his and then I go to check if the Citizen table contain this National ID or not. 
if yes I allow to he write additional information like email and phone then I will create new user by his data in the citizen table and additional data that he entered it then I will redirect to home page in the portal  . 
I didn't know How I will custom register page and login page( it refuse redirect to home page).
I read that I will need plugin called self registration. 
Please Can you help me?
Thank in advance.

Yes, this is doable, and you don’t need to customize login.do.

The usual approach is to use portal self-registration (or a custom portal registration page), not the login page itself.

What you want is:
User enters National ID → system checks the Citizen table → if found, allow email/phone → create a sys_user → redirect to portal home.

You can do this in two ways:

Best / closest to OOB
Enable self-registration for the portal and add a National ID field to the registration form. On submit, validate that National ID exists in your Citizen table. If it does, create the user using citizen data + entered fields. If not, show an error.

More custom
Create a custom portal “Register” page + widget. The widget checks the Citizen table via a Script Include, creates the user, then redirects to /sp?id=home.

If users are not redirecting after login/registration, that’s usually a portal entry page / redirect configuration issue, not a login issue.

At the end of the day:  don’t touch the login page; handle this in portal registration, then control the redirect to your home page.
