Question

I am developing Joomla 3.4 application.

But when this code run in topic controller then nothing display (NULL)

How to call model into another controller?

What problem I am facing. Any one have a idea.

Answer 1

$model  = $this->getModel('Checkout');
$data   = $model->getPriceBetween($pid);

Then you need to put query in getPriceBetween function in checkout model.
