Pagination gets complicated when finding specific groups of records when there is a large number of records are available.
By adding a search filter with pagination makes it easier for the user to easily find records e.g. filter list by country, department, name, etc.
It is easier to add pagination using pagination library in CodeIgniter.
In this tutorial, I am using the SESSION to store search value and filter the pagination list.
In CodeIgniter Model are the PHP classes where all database related manipulation is done e.g. fetching records, insert, update, and delete records.
Within this, all data processing logic is done.
All model files are managed in application/models directory and they are load and access by the controller.
If there is the registration form on the website then you need to make sure that the username or email must be unique.
The user will login with the selected username next time when it comes to the website.
You can either check it after submitting the form or while entering it.
In the demonstration, I am creating a simple registration form in CodeIgniter where check the entered username with Angular and insert the record if the username is available.
Data selection is required either to display information on the screen or use it for some data manipulation.
If you want to get records from the MySQL database using AngularJS in CodeIgniter then you need to create a method in the controller for handling the requests and return a response.
