How call function in a view File - nkhan - 05-31-2016

Hey , Guys.

I have a function in Controller as follows:

Path: controllers/category.php

Code:
public function get_category_name($parent_id=NULL)
    {
       if($parent_id==0){
           return 'Parent';
       }
       else{
           $child= $this->category_m->get($parent_id);
          
           return $child->title;
       }
        
    }

Now i want access that function product display page

Path : view/products/index.php

Code:
$CI=&get_instance();

echo $CI->get_category_name($product->cat_id);
                                         

 i have tried but the above code does not work , I am using Codeigniter 3.0.6.


Please Me .

You need to pass the variables with the desired content to the view instead of the other way around. You can have a look at the docs: http://www.codeigniter.com/user_guide/tutorial/static_pages.html

You cam also create a CI helper file and add your code there then it is global to the whole app.

Additionally, if a function is only going to be used internally by your application, you don't want it to be a public method on a controller. Any public method in a controller is callable from the URL/browser unless you prefix the function name with an underscore.
