将变量传递给视图CodeIgniter时失败

Question

I trying to pass $variable from CodeIgniter controller to a view but it's fail.

My controller code is:

class Index_controller extends CI_Controller {
    public function index(){
        $formURL = base_url().index_page().'authorization_controller/authorization';
        $attributes = array('class' => 'authorization','id' => 'authorization');
        $this->load->view('header');
        $this->load->view('leftFrame', $formURL, $attributes);
        $this->load->view('rightFrame');
        $this->load->view('index');
        $this->load->view('footer');
    }
}

My view code is:

<?php echo form_open($formURL, $attributes); ?>
</form>

Error message:

A PHP Error was encountered
Severity: Notice
Message: Undefined variable: formURL

and

A PHP Error was encountered
Severity: Notice
Message: Undefined variable: attributes

You need to pass the data in an array or an object. You can then access this data by referencing a variable of the same name as the array key in the view. You can achieve this like this:

public function index()
{
    $formURL = base_url().index_page().'authorization_controller/authorization';
    $attributes = array('class' => 'authorization','id' => 'authorization');

    // Data to pass to the view
    $view_data['formURL'] = $formURL;
    $view_data['attributes'] = $attributes;

    $this->load->view('header');
    $this->load->view('leftFrame', $view_data);
    $this->load->view('rightFrame');
    $this->load->view('index');
    $this->load->view('footer');
}
