How to modify the description of products in magento 2?

Question

I have a simple plugin in magento 2 that modifies the name of the products, but I can not find the function that modifies the description

public function afterGetName(\Magento\Catalog\Model\Product $subject, $result)
{
   return '|' . $result . ' - Test';
}

So modified the names of the products, I also have the function to modify the prices but what is the function to modify the description?

Answer 1

You can use plugin for all setter getters from product model. So to change description you can use

public function afterGetDescription(\Magento\Catalog\Model\Product $subject, $result)
{
   return '|' . $result . ' - Test';
}

Answer 2

Try to modify the getData($key) function. They usually call getDescription() or getData("description") to get the description.

Basically, in the system it always calls getData("description") function so you can modify that function to change the result.
