Inserting a barcode into the delivery slip

[TempleClause]

Hey there,

 

I'm pretty new with prestashop and need some advice on how I should do things. 

 

My goal: Insert a barcode into the delivery slip document which is created in php code. 

 

What would be the best and cleanest approach to do this? 

 

I figured out I could create a new Controller in the /classes/controller folder which extends AdminController. In there I could create a static function which does the job:

<?php

class MyController extends AdminController
{
    public static function myFunction($test){

	return "hello world";

    }
}

?>

From the delivery-slip.tpl file I could then call the function like this:

<p>
	Hello World!
	
	{MyControllerCore::myFunction()}
</p>

But I'm very unsure if this is the right way to do things. What would you guys recommend?

 

Thanks for pointing me in the right direction :-)
