How to create a Pagination in Codeigniter

In this tutorial will learn how to create “Pagination in CodeIgniter”.  In this tutorial, we used the CodeIgniter pagination class by initializing pagination library.

I am assuming you have already basic experience of working with the CodeIgniter framework before. Also, I will be sharing only partial code snippet related to pagination functionality.

Initializing pagination library and model.

public function __construct()
{
    parent::__construct();
    $this->load->model('Product_Model',"product_model");
    $this->load->library('pagination');
}

Rotes in CodeIgniter.

$route['ProductList']	= 'product/allProductList';
$route['ProductList(:num)']	= 'product/allProductList';

Initialization pagination library in Controller function.

public function allProductList()
{
    $config = array();
    $config["base_url"] = base_url() . "ProductList/";  
    $total_row   = $this->product_model->getproductList_count();
    $config["total_rows"] = $total_row;
    $config["per_page"] = 16;
    $config["uri_segment"]  = 2;
    $choice = $config["total_rows"] / $config["per_page"];
    $config["num_links"] = round($choice);
    $config['cur_tag_open'] = '&nbsp;<li class="active"><a >';
    $config['cur_tag_close'] = '</a></li>';
    $config['num_tag_open'] = '&nbsp;';
    $config['num_tag_close'] = '&nbsp;';
    $config['next_link'] = 'Next';
    $config['prev_link'] = 'Previous';
    $this->pagination->initialize($config);
    if($this->uri->segment(2)){
        $page = ($this->uri->segment(2)) ;
    }
    else{
       $page = 0;
    } 

    $data["productlist"] = $this->product_model->getproductList($config["per_page"], $page);
    $str_links = $this->pagination->create_links();
    $data["linked"] = explode('&nbsp;',$str_links );
    $this->load->view('product',$data);
}

Controller call in Model.

function getproductList_count()
{
    $query = $this->db->select('*');
    $query = $this->db->from('tbl_products');
    $query = $this->db->get();
    return $query->num_rows();
}

function getproductList($limit, $start)
{
    $query = $this->db->select('*');
    $query = $this->db->from('tbl_products');
    $query = $this->db->limit($limit, $start);
    $query = $this->db->get();
    return $query->result();
}

Now, finally, controller call in view.

if(!empty($linked))
{
?>
     <ul class="pagination" style="">
	 <?php foreach ($linked as $link) {
            ?>
		<li><?=$link?></li>
	  <?php } ?>
     </ul>
<?php }
?>

Here are Css that help to beautify your pagination block.

CSS Pagination format code
