pagination submit get value codeigniter - php

Question

I using GET method for searching records. now when i have applied pagination i can't understand how to submit data to next pagination page link.
I have tried this answer. but it is just stacking page number in link segments.
example:
From
localhost/phc/search/results/0?s=ai&product_cat=all&post_type=product
To
localhost/phc/search/results/?s=ai&product_cat=all&post_type=product/12/24
so i didn't used that code.
And now my code is:
public function results() {
//pagination
$offset = $this->uri->segment(3);
$limit = 12;
//$offset = 0;
$data['limit'] = $limit;
$config['base_url'] = base_url() . 'search/results/';
$config['first_url'] = base_url() .'search/results/0';
$data['total'] = $this->All_data_model->countSearchProducts($_GET);
$config['total_rows'] = $data['total'];
$config['per_page'] = $limit;
$config['uri_segment'] = 3;
$config['next_link'] = 'Next';
$config['prev_link'] = 'Previous';
$this->pagination->initialize($config);
$data['pagination'] = $this->pagination->create_links();
$data['offset'] = $offset;
$data['total_rows'] = $config['total_rows'];
$data['page'] = 'search';
$data['navbar'] = $this->All_data_model->navbarContent();
$data['products'] = $this->All_data_model->searchResults($_GET , $offset , $limit);
$this->template->write_view('content', 'products/search', $data);
$this->template->render();
}
Tell what the best way to submit data in this case if not GET and how can i access this data.

Answer 1

Put offset in your url
localhost/phc/search/results?s=ai&product_cat=all&post_type=product&offset=123
and set these configs.
$config['page_query_string'] = TRUE;
$config['query_string_segment'] = 'offset';
$config['reuse_query_string'] = TRUE;
I changed your code but it's not tested at all.
public function results() {
//pagination
$offset = $this->input->get('offset') ? $this->input->get('offset') : 0;
$limit = 12;
$data['limit'] = $limit;
$config['base_url'] = base_url() . 'search/results/';
$data['total'] = $this->All_data_model->countSearchProducts($_GET);
$config['total_rows'] = $data['total'];
$config['per_page'] = $limit;
// set these mostly...
$config['page_query_string'] = TRUE;
$config['query_string_segment'] = 'offset';
$config['reuse_query_string'] = TRUE;
$config['next_link'] = 'Next';
$config['prev_link'] = 'Previous';
$this->pagination->initialize($config);
$data['pagination'] = $this->pagination->create_links();
$data['offset'] = $offset;
$data['total_rows'] = $config['total_rows'];
$data['page'] = 'search';
$data['navbar'] = $this->All_data_model->navbarContent();
$data['products'] = $this->All_data_model->searchResults($_GET , $offset , $limit);
$this->template->write_view('content', 'products/search', $data);
$this->template->render();
}
