RRP Prestashop 1.7

[RobertCR]

Hello!

 

I am trying to add a RRP(recommended retail price) field to my website for each product.

 

At the moment I have added this 

'pricerrp' =>                    array('type' => self::TYPE_FLOAT, 'shop' => true, 'validate' => 'isPrice', 'required' => true),

and this

   public $pricerrp = 0;

But I do not know how to add the field to the back office and then display it in the front-office in the .tpl file.

 

Any help?

thanks
