             $builder = $db->table('fullname');
             $builder->insert($data);
         }
     }

protected $table = 'fullname'; //table name
protected $allowedFields= ['name','surname','email','password']; //column name of table
}
?>

Controller - User.php

<?php namespace App\Controllers;
use App\Models\UserModel;
use CodeIgniter\Controller;

class User extends BaseController
{
     public function index()
     {
         return view('home');
     }

         $data = [ 'name' =>$this->request->getVar('name'),
             'email' =>$this->request->getVar('email'),
             'password' =>$this->request->getVar('password') ];
