Codeigniter - Pagination not working - php

Question

I'm having some problems with Codeigniter and the pagination. The problem is that I get all the results/posts on all pages.
I'm having some problems with Codeigniter and the pagination. The problem is that I get all the results/posts on all pages.
Here is my Controller Code:
public function __construct()
{
parent::__construct();
$this->load->model('SS_shilpi_model');
$this->load->library('form_validation');
$this->load->library('pagination');
}
public function category(){
$cid = $this->input->post('cid');
if(isset($_GET['cid']))
{
$cid = $_GET['cid'];
$this->SS_shilpi_model->catr3($cid);
$this->SS_shilpi_model->catr3_nr($cid);
}
$config = [
'base_url' => base_url('category/?cid='. $cid .' '),
'per_page' => 12,
'total_rows' => $this->SS_shilpi_model->catr3_nr($cid),
];
$config['full_tag_open'] = '<ul style="overflow: hidden;" class="pagination">';
$config['full_tag_close'] = '</ul>';
$config['num_tag_open'] = '<li class="page-item">';
$config['num_tag_close'] = '</li>';
$config['cur_tag_open'] = '<li class="page-item active"><a class="page-link" href="#">';
$config['cur_tag_close'] = '</a></li>';
$config['next_tag_open'] = '<li class="page-item">';
$config['next_tagl_close'] = '</a></li>';
$config['prev_tag_open'] = '<li class="page-item">';
$config['prev_tagl_close'] = '</li>';
$config['first_link'] = 'First <i class="fa fa-caret-left fa-2x push-left-5 pull-right green-text"></i>';
$config['first_tag_open'] = '<li class="page-item disabled">';
$config['first_tagl_close'] = '</li>';
$config['last_link'] = '<i class="fa fa-caret-right fa-2x push-left-5 pull-right green-text"></i> Last';
$config['last_tag_open'] = '<li class="page-item">';
$config['last_tagl_close'] = '</a></li>';
$config['attributes'] = array('class' => 'page-link');
$this->pagination->initialize($config); // model function
$data['catr3d'] = $this->SS_shilpi_model->catr3($cid, $config['per_page'], $this->uri->segment(3)); // list of Category Details
// end pagination
$this->load->view('shilpi/category',$data);
}
My Model Code :
public function catr3($cid){
$this->db->select('');
$this->db->order_by('id', 'DESC');
$this->db->where('category_id',$cid);
$query = $this->db->get('all_posts');
return $query->result();
}
public function catr3_nr($cid){
$this->db->select('');
$this->db->order_by('id', 'DESC');
$this->db->where('category_id',$cid);
$query = $this->db->get('all_posts');
return $query->num_rows();
}
My view code :
<div id="catdata" class="col-xs-12 no-pull push-up-5 push-down-5 briefs">
<?php
$count =1;
foreach($catr3d as $r)
{
if($count%4 == 1)
{
echo '<div class="col-xs-12 no-pull push-down-5">';
}
?>
<div class="col-sm-3 col-xs-12 no-pull-left pull-right-5">
<div class="brief whitish-bg pull-5">
<p class="red-text no-push">
<?php echo $r->short_title; ?>
</p>
<a href="<?php echo base_url(); ?>details/?pid=<?php echo $r->id; ?>">
<h5 class="blue-text font17 push-up-5">
<?php echo $r->title; ?>
</h5>
</a>
<p>
<a href="<?php echo base_url(); ?>details/?pid=<?php echo $r->id; ?>">
<img src="<?php echo base_url(); ?>upload/images/<?php echo $r->photo;?>" height="75" width="100" class="pull-left push-right-5 push-up-5"></img>
</a>
<?php
$string = $r->news;
$string = strip_tags($string);
if (strlen($string) > 500) {
$pos=strpos($string, ' ', 900);
$stringCut=substr($string,0,$pos );
echo $stringCut;
}
else {
echo $string;
}
?>
<i class="fa fa-caret-right fa-2x push-left-5 pull-right green-text"></i>
</p>
</div>
</div>
<?php
if ($count%4 == 0)
{
echo "</div>";
}
$count++;
?>
<div class="clear: both"></div>
<?php
}
if ($count%4 != 1) echo "</div>";
?>
<?= $this->pagination->create_links() ?>
</div>

Add This to Controller start and limit to your model function argument
$page = ($this->uri->segment(3)) ? $this->uri->segment(3) : 0;
$data['posts'] = $this->post->get_posts($config["per_page"], $page);
And following to model function get_posts
$this->db->limit($limit, $start);
