   function _buildDataObject() {
       // Initialize variables

Pagination like Google

Warning!

This is a core hack. Files you change as described on this page will be overwritten during updates of Joomla!. For more information, see Core hack.

  • edit the libraries/joomla/html/pagination.php
  • In the function __construct see the line $displayedPages = 10;
  • Replace the $this->set( 'pages.start',... with the following lines
  $_remainder = $this->get('pages.current') % $displayedPages;
  if($__remainder == 0){
     $this->set( 'pages.start', (floor( $this->get('pages.current') / $displayedPages)) * $displayedPages -4);  
  }elseif($__remainder == 1 and $this->get('pages.current') > $displayedPages){
     $this->set( 'pages.start', (floor( ($this->get('pages.current')-1) / $displayedPages)) * $displayedPages -4);  
  }else{
    $this->set( 'pages.start', (floor( $this->get('pages.current') / $displayedPages)) * $displayedPages + 1);
  }
  • In the function _buildDataObject find the line
 for ($i = $this->get('pages.start'); $i <= $stop; $i ++)
  • In this for loop, find the line
 if ($i != $this->get('pages.current') || $this->_viewall)
  • Add the elseif statement,
 if ($i != $this->get('pages.current') || $this->_viewall)
 {
   $data->pages[$i]->base = $offset;
   $data->pages[$i]->link = JRoute::_("&limitstart=".$offset);
 }elseif($i == $this->get('pages.current')){
   $data->pages[$i]->text = '<b>' . $i . '</b>';
 }
