how to keep the variable passed to the view in codeigniter 4

You don't need to pass the model to the view.
This is bad practice.

PHP Code:

cateMenu =1
$getcateMenu =$mhome->function('1') 


can you  good method to get id folow cate in view page ? i know 'view_ceil' in codeigniter 4 , but id dont like this function

I don't know the logic of your application.
For example, you can create a service that will prepare data for display.
This is a simple example to show the concept.

PHP Code:

class MyService
{
    public function doSomething()
    {
        $data = ['...'];
        \Config\Services::renderer()->setData($data);
        
        return $this;
    }

    public function doSomething2()
    {
        $data = ['...'];
        \Config\Services::renderer()->setData($data);
        
        return $this;
    }
}

class MyController extends Controller
{
    public function index()
    {
        $ms = new MyService();
        $ms->doSomething()->doSomething2();
        
        return view('template');
    }
}
