将值从视图传递到控制器而不使用表单/字段

Question

How to pass value from view to controller without using form/fields? I mean send value from view to controller via link.

View:

<?php foreach ($languages as $lang) { ?>
     <li>
       <a href="<?php echo base_url(); ?>home/box/<?php echo $template_data['box_id']?>/<?php echo $lang['language_name']?>"></a>
     </li>
 <?php } ?> 

Controller:

public function passby($page) {    
    $uri = 'admin/'.$page;
    $this->load->view('header');
    $this->load->view('admin/navigation');
    $this->load->view('admin/sidebar');
    $this->load->view($uri);
    $this->load->view('footer');
}

I don't know about your specific framework, but in general PHP if you want to pass variables via a link you use parameters on the querystring like this:

http://www.example.com/myPage.php?var1=x&var2=y

Then in myPage.php you can access them like this:

$var1 = $_GET["var1"];
$var2 = $_GET["var2"];

You use $_GET because the variables were passed on the querystring (i.e. a GET request), as opposed to $_POST which you'd use if the variables were submitted via a form.
