How to extend PagerRenderer and add additional methods
#1

Hello, I'm trying to extend pagination of codeigniter4, so I can be able to use it with ajax.
If I add directly my custom method to CodeIgniter\Pager\PagerRenderer, they works fine. But I want to use them through Libraries directory.
So I can be able to use like this
PHP Code:
<?php 
namespace App\Libraries\Pagination;
use 
CodeIgniter\Pager\PagerRenderer;

class 
Pagination extends PagerRenderer
{
 
   public function __construct()
   {
       // parent::__construct();
   }
    
    
// Get First Page Number 
    public function getFirstPageCounter(): int
    
{
        if ($this->segment === 0){
            $firstPage 1;
        }else{
            $firstPage $this->segment;
        }
    
        
return (int) $firstPage;
    }
    
    
// get Last page Number
    public function getLastPageCounter()
    {
        if ($this->segment === 0){
            $last $this->pageCount;
        }else{
            $last $this->segment;
        }
        return (int)$last;
    }
    
    
// Get previous Page number
    public function getPreviousPageCounter()
    {
        if (! $this->hasPrevious()){
            return null;
        }
    
        
if ($this->segment === 0){
            $previous $this->first 1;
        }else{
            $previous $this->segment;
        }
    
        
return (int) $previous;
    }
    
    
// get Next Page Number
    public function getNextPageCounter()
    {
        if (! $this->hasNext()){
            return null;
        }
    
        
if ($this->segment === 0){
            $next $this->last 1;
        }else{
            $next $this->last 1;
        }
        return (int) $next;
    }
}

//nav templates links 

//html navigation template
PHP Code:
<?php if ($pager->hasNext()) : ?>
<li>
<a href="<?= $pager->getNext()?>" data-page="<?= $pager->getNextPageCounter() ?>">
</a>
</li>
<li>
<a href="<?= $pager->getLast()?>  data-page="<?= $pager->getPreviousPageCounter() ?>">
</a>
</li>
<?php endif ?>

Thanks in advance.

It seems there is no way to replace the PagerRenderer class.
It is hard coded:

You could do it like this:
1. Extend the Pager class to use your PagerRenderer.
2. Replace the Pager class. See https://codeigniter4.github.io/CodeIgnit...re-classes
