magento2 – Magento 2: how to perform operations after updating the price of the product from the backend

You must develop your question to get an appropriate answer. As – What kind of operation do you want to perform and when do you need to perform after updating the product price from the backend?

Such an example – If you want to update the product price of the article added to the cart, you must use the Object Manager:

$cart = $objectManager->get('MagentoCheckoutModelCart');
$priceHelper = $objectManager > create('MagentoFrameworkPricingHelperData');
$items = $cart->getQuote()->getAllItems();

Invalid document error di.xml for the product form modifier

I'm trying to customize the product creation form with the aid of the modifier class

it's my di.xml



    
        
            
                
                    AddOnSystemProductApprovalUiDataProviderProductFormModifierCustomField
                    20
                
            
        
    

and that's my modifier class

getAuth();
        $loginUser=$auth->getUser();
        $loginUserRole=$loginUser->getRole();
        $this->role = $loginUserRole;
        $this->arrayManager = $arrayManager;
        $this->locator = $locator;
        $this->helper = $helper;
    }

    public function modifyData(array $data)
    {
        return $data;
    }

    public function modifyMeta(array $meta)
    {
        $disabled = true;
        $role = $this->role;
        $roleList = $this->helper->getGeneralConfig('listrole');

        if(in_array($role('role_id'), $roleList)){
            $disabled = false;
        }

         $switcherConfig = (
            'disabled' => $disabled,
        );

        $path = $this->arrayManager->findPath('addonsys_product_approval', $meta, null, 'children');
        $meta = $this->arrayManager->merge($path . static::META_CONFIG_PATH, $meta, $switcherConfig);

        return $meta;
    }
}

the problem is when I try to do bin / magento he throws a mistake

Abstract algebra – Vakil's Exercise 1.3.K (b): natural ring structure of a tensor product

This problem is based on the foundations of Vakil's algebraic geometry (Exercise 1.3.K. (b)):

Problem: Yes $ varphi: A to B $ and $ psi: B to C $ are two morphisms of the rings, show that $ B otimes_A C $ has a natural structure of a ring.

In his notes, Vakil even gives us the multiplication: $$ (b_1 otimes c_1) (b_2 otimes c_2): = (b_1 b_2) otimes (c_1 c_2). $$

Now, I do not understand why we need cards in the first place. I know it $ B $ and $ C $ can get a $ A $-module structure via $ varphi $ resp. $ psi $, so the notion $ B otimes_A C $ logic. However, why can not we just take arbitrary rings $ B $ and $ C $. While I was trying to go through all the axioms of the ring with the above multiplication, it seems to me that every axiom is always correct.

Could you let me know what I'm missing here? Thank you!

Determine the product for which the Enable RMA option is set to NO.

I set one of my products "Enable RMA" to "No". I do not remember which one. How can I find it?
I thought about exporting the product and then finding the column for the Enable RMA attribute. But it seems that "Enable RMA" is exported. I do not see it anywhere in the Magento User Guide.

schema.org – Rich schema and extract for a website having only one review (non-user) of each product?

It seems that the most relevant structured data type of analysis is the critical examination. Indeed, it is not a combined score of evaluations submitted by many users who would use the user evaluation scheme. It also meets Google's criteria for a review:

  • Authoritative human author [s] must create, organize, or compile content for critics.
  • Include only critical reviews directly produced by your site, not third-party reviews or critical reviews.
  • Do not add structured data to reviews of products or services for adults.

However, Google will probably not use the structured data from the Game Reviews website. Google says it will only show rich snippets of criticism for:

  • Local businesses
  • Movies
  • Books

As long as Google does not display the number of stars of game reviews, the implementation of structured data on your site does not present any benefit. If you had to implement it, you should expect Google to start showing the star rating for game reviews in the future.
