Call function in cart-detailed-product-line

[13thjoker]

So i wrote the next function in CartConroller.php

    public function TestFunction()
    {
        $page = "hi"
        return $page;
    }

And then tried to use the function using

{Cart::TestFunction()}

Can somebody point out what i need to do to make it work

Thanks already

If you want to call function by this way - you need to create static function

class ClassName {
	// need instance of class
	public function TestFunction()
    {
        $page = "hi"
        return $page;
    }
	// call staticaly by class name
	public static function TestFunctionStatic()
    {
        $page = "hi"
        return $page;
    }
}

this example help you to understand

// create object instance
$testObj = new ClassName();
// call public method
$testObj->TestFunction(); // will return "hi"


// call static method
$testObj = ClassName::TestFunctionStatic();
// $testObj now contains "hi"

Update: it gives me this now

UndefinedMethodException in smarty_internal_templatebase.php(171) : eval()'d code line 882: Attempted to call an undefined method named "TestFunctionStatic" of class "CartControllerCore".
