CodeIgniter: ne pas pagination point d'interrogation?

Question

Le code ci-dessous génère à l'aide des chaînes de pagination requête. Cependant, il n'y a pas de premier plan ?. Donc, je reçois quelque chose comme ceci: http://localhost/index.php/search/&limit=10. Toutes les idées pourquoi?

this->load->library('pagination');

$config                   = array();
$config['base_url']       = 'http://localhost/index.php/search/';
$config['total_rows']     = 200;
$config['per_page']       = 10;
$config['num_links']      = 4;

$config['full_tag_open']  = '<ol>';
$config['full_tag_close'] = '</ol>';

$config['first_link']      = 'First';
$config['first_tag_open']  = '<li>';
$config['first_tag_close'] = '</li>';

$config['last_link']      = 'Last';
$config['last_tag_open']  = '<li>';
$config['last_tag_close'] = '</li>';

$config['next_link']      = 'Next';
$config['next_tag_open']  = '<li>';
$config['next_tag_close'] = '</li>';

$config['prev_link']      = 'Previous';
$config['prev_tag_open']  = '<li>';
$config['prev_tag_close'] = '</li>';

$config['cur_tag_open']  = '<li class="active">';
$config['cur_tag_close'] = '</li>';

$config['num_tag_open']  = '<li>';
$config['num_tag_close'] = '</li>';

$this->pagination->initialize($config);
echo ($this->pagination->create_links());

EDIT 2:

Les documents semblent indiquer que ce que je ne devrais travailler: http://codeigniter.com/ User_Guide / bibliothèques / pagination.html

$config['page_query_string'] = TRUE;

Par défaut, la bibliothèque de pagination suppose que vous utilisez segments URI, et construit vos liens quelque chose comme

http://example.com/index.php/test/page/20

Si vous avez défini $config['enable_query_strings'] à vos liens TRUE sera automatiquement ré-écrit à l'aide de chaînes de requête. Cette option peut également être réglée explictly. Utilisation de set de $config['page_query_string'] à TRUE, le lien deviendra la pagination.

http://example.com/index.php?c=test&m=page&per_page=20

Je l'ai moi-même courir dans. Lors de l'utilisation des chaînes de requête, CodeIgniter doit supposer que vous avez d'autres paramètres de chaîne de requête (MAIS, CI suppose que vous utilisez les paramètres de chaîne de requête pour mapper votre contrôleur et méthode ...). Je aime utiliser la chaîne de requête pour des trucs comme les résultats de filtrage et autres, tout en utilisant les options de routage de base dans l'URI (comme vous).

J'ai dû vivre avec le & personnellement, mais je suppose que vous pouvez étendre la bibliothèque Pagination comme si (longue fonction, désolé):

class MY_Pagination extends CI_Pagination {
function create_links()
{
    // If our item count or per-page total is zero there is no need to continue.
    if ($this->total_rows == 0 OR $this->per_page == 0)
    {
        return '';
    }

    // Calculate the total number of pages
    $num_pages = ceil($this->total_rows / $this->per_page);

    // Is there only one page? Hm... nothing more to do here then.
    if ($num_pages == 1)
    {
        return '';
    }

    // Determine the current page number.
    $CI =& get_instance();

    if ($CI->config->item('enable_query_strings') === TRUE OR $this->page_query_string === TRUE)
    {
        if ($CI->input->get($this->query_string_segment) != 0)
        {
            $this->cur_page = $CI->input->get($this->query_string_segment);

            // Prep the current page - no funny business!
            $this->cur_page = (int) $this->cur_page;
        }
    }
    else
    {
        if ($CI->uri->segment($this->uri_segment) != 0)
        {
            $this->cur_page = $CI->uri->segment($this->uri_segment);

            // Prep the current page - no funny business!
            $this->cur_page = (int) $this->cur_page;
        }
    }

    $this->num_links = (int)$this->num_links;

    if ($this->num_links < 1)
    {
        show_error('Your number of links must be a positive number.');
    }

    if ( ! is_numeric($this->cur_page))
    {
        $this->cur_page = 0;
    }

    // Is the page number beyond the result range?
    // If so we show the last page
    if ($this->cur_page > $this->total_rows)
    {
        $this->cur_page = ($num_pages - 1) * $this->per_page;
    }

    $uri_page_number = $this->cur_page;
    $this->cur_page = floor(($this->cur_page/$this->per_page) + 1);

    // Calculate the start and end numbers. These determine
    // which number to start and end the digit links with
    $start = (($this->cur_page - $this->num_links) > 0) ? $this->cur_page - ($this->num_links - 1) : 1;
    $end   = (($this->cur_page + $this->num_links) < $num_pages) ? $this->cur_page + $this->num_links : $num_pages;

    // Is pagination being used over GET or POST?  If get, add a per_page query
    // string. If post, add a trailing slash to the base URL if needed
    if ($CI->config->item('enable_query_strings') === TRUE OR $this->page_query_string === TRUE)
    {
        $this->base_url = str_replace('?&amp;', '?', rtrim($this->base_url).'&amp;'.$this->query_string_segment.'=');

    else
