Change url after loading a view in codeigniter [duplicate]

Possible Duplicate:
Change url in php after reloading a page

I might be repeating my question but i am providing the exact scenario this time with my actual code Kindly be patient with me ... My Home page URL is

http://localhost/mediabox/home/box/12

on my home page I have two links for languages when I click on any of the link the page reloads with the content in that specific language.

The link is inside a view (template/index) and looks like this

<a href="<?php echo base_url(); ?>home/box/?bid=<?php echo $template_data['box_id']?>&ln=<?php echo $lang['language_id']?>"></a>

So i am sending bid and ln as qurystring with the link

Now when I click on the link the content of the page changes according to the language selected but the url also changes to

http://localhost/mediabox/home/box/?bid=12&ln=2

What i want is that the content of the page changes but not the url or can I make the url looks like this after loading the page

http://localhost/mediabox/home/box/12/language_name

The method in my controller that loads the home page and change the content when a language link is clicked is as follows

    public function box() {
        $url = $this->pageURL();
        $id_from_url = explode('/', $url);

        if (isset($_GET['bid'])) {
            $id = $this->input->get('bid');
        }
        else{
            $id = $id_from_url[6];
        }
        $query = $this->db->get_where('mc_boxes', array('idmc_boxes' => $id));
        $row = $query->row();
            if (isset($_GET['bid'])) {
                $box_id = $this->input->get('bid');
            } 
            else {
                $box_id = $row->idmc_boxes;
            }
            $customer_id = $row->customers_idcustomers;
            if (isset($_GET['ln'])) {
                $language_id = $this->input->get('ln');
            }
            else {
                $language_id = $row->languages_idlanguages;
            }
            $template_id = $this->Home_model->getTemplateID($box_id);
            $data['template_data'] = $this->Home_model->getTemplateData($template_id);
            $data['variables_data'] = $this->Home_model->getVariables($customer_id, $language_id);
            $data['titles_data'] = $this->Home_model->getTitles($box_id,$language_id);
            $data['categories'] = $this->Home_model->getCategories($customer_id, $language_id);
            $data['languages'] = $this->Home_model->getLanguages($box_id);
            $this->load->view('template/index', $data);

    }

Any ideas please ?

Thanks in advance

Hi Faryal - wouldn't it be better to edit your old question? :) — halfer

Why pass by GET? You could pass values straight into the controller by doing <a href="<?php echo base_url(); ?>home/box/<?php echo $template_data['box_id']?>/<?php echo $lang['language_id']?>"></a> Then reading this into your controller like; public function box($box_id, $ln) {...} — Rooneyl

@ Rooneyl but when I load my home page for first time I dont have that ln variable Do i need to change my routes as well ? — Faryal Khan

@FaryalKhan, just give it a default value in the contoller. E.g. public function box($box_id, $ln=1) {...} — Rooneyl

You can define multiple arguments for controller functions. But multiple arguments must have default value.

public function box($id, $language = 'en') {
    echo "id: " . $id . " - lang: " . $language;
}

when your link http://localhost/mediabox/home/box/12/language_name

this will return,

id: 12 - lang: language_name

You have a few options as to how to extract data from the URI. Here are just two.

Every segment after box/ in the URI will be passed as an argument to the box method as levye suggested.
Use the URL class to get the information you need.

You should be OK with method 1. Once you get into remapping and rewriting URLs then method 2 will sometimes be your salvation.

I suggest reading this page from the CI manual to help you better understand how to pass data to your controllers.

This might help you understand the magic.

Put die(var_dump($this->uri->segment_array())); as the first line in your controller and then access http://localhost/mediabox/home/box/this_is_argument_1/this_is_2/4/500/six/ from your browser. $this->uri->segment(3); will hold the string this_is_argument_1, $this->uri->segment(5) == 4; etc. Keep in mind that segment 1 is the name of the controller and 2 is the name of the method being called.

Also note that the URL Class is initialized automatically by codeigniter so there is no need to load it manually (nor do you need to explode() or anything like that).
