Here is the solution:
Extend the Codeigniter breakdown class by creating a new file: MY_Pagination.php and placing it in the application/library folder.
Change all variable and class prefix declarations from protected to public .
Define two public variables in MY_Pagination.php: $display_prev_link and $display_next_link and set it to FALSE .
In the create_links () function, add at the end of the if ($this->prev_link !== FALSE && $this->cur_page !== 1) elseif statement:
elseif ($this->display_prev_link && $this->cur_page === 1) $output .= $this->prev_tag_open.'<span>'.$this->prev_link.'</span>'.$this->next_tag_close;
and another elseif statement at the end of the if ($this->next_link !== FALSE && $this->cur_page < $num_pages) :
elseif ($this->display_next_link && $this->cur_page >= $num_pages) $output .= $this->next_tag_open.'<span>'.$this->next_link.'</span>'.$this->next_tag_close;
So,
By setting $config['display_prev_link'] and $config['display_prev_link'] to TRUE or FALSE , you can control the presentation of the Previous and Next links.
