Why we writing loading view last code variable codeigniter

Question

Why do I pass a variable name when calling a view file?

For example: $this->load->view("{$viewData->viewFolder}/{$viewData->subViewFolder}/index", $viewData);

Why we writing $viewData at a last code line?

Answer 1

no need to load variable:

$data['view'] = 'folername/view_file_namae';
$this->load->view('you can call common file for header/footer here', $data);

Answer 2

To pass a variable name to view file,

$this->data['anyname'] = $variable;
$this->load->view('viewfilename',$this->data);

and In your view file name, access your passed data as echo $anyname;. You can pass a variable or an array as you want.

If you want to append a variable name to a view file, you can use redirect() function.

e.g.

redirect('home/category/'.$variable, 'refresh');
redirect('home/category/subcategory/'.$variable, 'refresh');
