Question

I’m using CodeIgniter Framework in order to build a web application as follows.

My default controller is something like this,

class Start extends CI_Controller {
    public function index() 
    {  
        $view_data = array(
            'foo' => 'bar',
            'top_bar_view' => 'top_bar_view',
            'top_bar_params' => array(
                'param1' => 'val1',
                'param2' => 'val2',
                'param3' => 'val3', 
                'param4' => 'val4',
                'param5' =>  'val5'
            )
        );
        $this->load->view('main_view', $view_data);
    }
} 

which loads the main_view, that is kind of master page, where I load the view file that I’m passing with $view_data.

Then, on this top_bar_view I would like to call a controller in order to build a menu depending on some data. For now, I accomplish this using an AJAX call inside this partial view.

script type="text/javascript">
    $(function() {
        $.post('index.php/menu/givemenu', {}, function(data) { 
             $('#topMenuBar').append(data); });
        });

<img alt="alt_data" src="assets/img/<?php echo $image_name; ?>" />
<div>
    <img alt="<?php echo $descricao_editora; ?>" src="assets/img/<?php echo $image_name; ?>" />
</div>
<div class="divSpacer20pxRight"></div>
<div class="divTituloProduto">
    <?php echo $titulo_produto; ?>
</div>
<div class="clear"></div>
<div id="topMenuBar" class="divTopMenuBar"></div>
<div class="clear"></div> 

Is this correct and respects the MVC Framework?

Answer 1

I personally don’t like that kind of solution but “Is it correct” is relative but I would create a MY_Controller that will be extended from all my other controllers and add the givemenu method so I can call it from all controllers. On your controllers index method, you call it and add its return to your array and pass it to the view.
