Question

I use the following code in my controller. But the data[‘msg’] is not being passed to the view file.

Code:

class Operator{


public function view ($page)
{
    if ( ! file_exists('application/views/pages/'.$page.'.php'))
    {
        // Whoops, we don't have a page for that!
        show_404();
    }

    $data['title'] = $this->getTitle($page); 
    $this->load->view('templates/header', $data);
    $this->load->view('pages/'.$page, $data);
    $this->load->view('templates/footer', $data);

}
public function create_company()
{
        // some code
    $data['msg1']='my mesg';
    redirect('operator/view/operator_success','refresh');
}
};

When operator_success(view page) is loaded it show error message: variable ‘$msg1’ not defined.

After Redirect you cannot use the variable or array. Instead setting the variable keep in session or CodeIgniter Flash Data.

class Operator
{

    public function view($page)
    {
        if (!file_exists('application/views/pages/' . $page . '.php')) {
            // Whoops, we don't have a page for that!
            show_404();
        }

        $data['title'] = $this->getTitle($page);
        $this->load->view('templates/header', $data);
        $this->load->view('pages/' . $page, $data);
        $this->load->view('templates/footer', $data);
    }

    public function create_company()
    {
        // some code
        $data['msg1'] = 'my mesg';

        // DO THIS 
        $this->session->set_flashdata('msg1', 'my mesg');
        // OR 
        $this->session->set_userdata('msg1', 'my mesg');
        redirect('operator/view/operator_success', 'refresh');
    }

}

After redirect you can simply call the flashdata.

echo $this->session->flashdata('msg1');
// OR
echo $this->session->userdata('msg1');

You must initialize the session before use, either autoload the session library or load manually.

[ 1 ] Autoload the session library (config/autoload.php)

$autoload['libraries'] = array('session');

[ 2 ] Manually load the library

$this->load->library('session');

see more about session and flash data here. Hope this helps you. Thanks!!
