Magento 2 plugin change price of products that have a custom attribute with












0














I'm trying to change the prices of products with a plugin. And it works, basically. The problem is this: i only need to change the price of products that have a specific attribute, not the price of all products. With a plugin, it's easy to add a fixed value to the price of a product, but i can't figure out how to check if the product has that custom attribute. this is the code I'm using: 



namespace FrostmageWBTPDCPlugin;



class Product

{





    public function afterGetPrice(MagentoCatalogModelProduct $subject, $result)

    {



        $objectManager = MagentoFrameworkAppObjectManager::getInstance();

        $wbtvalue = $objectManager->get('MagentoFrameworkAppConfigScopeConfigInterface')->getValue('wbtpdc/modifier/variable');





        return $result * $wbtvalue;

    }

}


Now... It works for the value I added, but I need to add a check, sort of like this: 



if ($subject->getData('has_wbt'))

{

    return $result + ($wbtvalue * $subject->getData(weight));

}


Thing is that $subject is not the right variable to use (I wrote that just to exemplify what I need to do). If I try to use objectManager to create a $current_product variable, it always returns an exception for calling getData on null. If I use $subject, it always returns 0. So this is the problem: How can I change the price only of products that have 'has_wbt' attribute so that it shows on the frontend?
I mean, is there a way to have this plugin only act on products that have a specific attribute?

          Now Go to the Store->Product Attribute->Edit Your Attribute->Storefront Properties->Used in Product Listing->Yes



          Then save your attribute.

          An IMO inspired problem

          Image
          14 4 This problem from IMO 1988 is said to be one of the most elegant ones in functional equations. Problem : The function $f$ is defined on the set of all positive integers as follows: begin{align} f(1) = 1, f(3) &= 3, f(2n) = f(n), \ f(4n+1) &= 2f(2n+1) - f(n), \ f(4n+3) &= 3 f(2n+1) - 2f(n) end{align} Find the number of $n$ with $f(n) = n, 1 leq n leq 1988$. The main idea towards the solution is realizing that these conditions stand for the fact that $f(n)$ just reverses the digits in the binary representation of the number $n$. So, essentially the solution is finding the number of binary pallindromes $leq 1988_{10}$. My question is the following : How to reformulate the problem so that $f(n)$ reverses the digits of $n$ in its ternary representation. Or even better, can we reformulate it for a

          Has there ever been an instance of an active nuclear power plant within or near a war zone?

          Image
          36 3 The question Has there ever been a military combat going on around an active (running or in outage but not decommissioned) commercial nuclear power plant? Or dangerously near it? If yes, how did the plant and its personnel fare in such situation? Why I ask Let's assume for the scope of this question modern commercial nuclear power plants (CANDU, PWR, BWR of generation II plus all of gen III and newer) are usually reasonably safe to operate given that the engineering has been done right and there is a whole cohort of very well trained personnel on-site at all times, well rested and with considerable resources on their hands. Things hard to get with an armed conflict like the recent Syrian war raging around. I can't seem to find any reference or a comprehensive article about this, hence this question.
