CodeIgniter: Friendly pagination with search system - View Page

[eluser]ronald_allan_rivera[/eluser]
Can someone help me create the VIEW page for the following library and controller.

I got this source code on http://www.vrusso.com.br/blog/2009/01/co...anguage=en


library/Pagination_search.php

Code:

    var $per_page             = 10; // Max number of items you want shown per page
    var $num_links            =  2; // Number of "digit" links to show before/after the currently viewed page
    var $cur_page             =  0; // The current page being viewed
    var $first_link           = '‹ First';
    var $next_link            = '>';
    var $prev_link            = '<';
    var $last_link            = 'Last ›';
    var $uri_segment        = 3;
    var $full_tag_open        = '';
