CI Pagination Back to Posts Link - php

Question

I'm learning CI and latest I've been tasked to do is pagination. So I followed this tutorial as it seemed relatively nicely made and explained. Link
The pagination works and its great. Now I wanted to make a read more under each post, making each post open separately with its full description. That also works, but when I click a link to go back to the pagination index, the list starts from the beginning, no matter which post I clicked. I'm not sure how to add the page I want the return link to take me back so I'll just post this here and hopefully it won't be too hard for someone to tell me.
If someone is confused what I'm after, just look at the last view readmore_paginate. In it, the last link should contain a number back
to the page, but idk how to put or what to put there.
Controller
public function paginate()
{
$config = array();
$config['base_url'] = base_url()."welcome/paginate";
$config['total_rows'] = $this->blog_model->countPosts();
$config['per_page'] = 2;
$config['uri_segment'] = 3;
$this->pagination->initialize($config);
$page = ($this->uri->segment(3)) ? $this->uri->segment(3) : 0; //TERNARY OPERATOR (? = TRUE) (: = FALSE)
$data['results'] = $this->blog_model->fetchPosts($config['per_page'], $page);
$data['links'] = $this->pagination->create_links();
$this->load->view('header');
$this->load->view("p_content", $data);
$this->load->view('footer');
}
public function readMore_Paginate()
{
$id = $this->input->get('postid');
$data['post'] = $this->blog_model->getSpecificPost($id);
$this->load->view('header');
$this->load->view('readmore_paginate', $data);

$this->uri->segment(3) :
0;
$data['results'] = $this->blog_model->fetchPosts($config['per_page'], $page);
