Set minimum qty for checkout - across multiple catagories

[neilkerry]

Hi All,

I am looking for a solution for the following - Need to specify a min product requirement to allow checkout to proceed based on multiple products from multiple categories.

Example:

Category ID:4, ID:5 and ID:6 – min qty allowed to checkout is ANY 15 products from any of these categories. Products can be mixed and matched from categories but must meet the minimum to proceed.

Category ID:9 and ID:3 – min qty allowed to checkout is ANY 7 products from any of these categories. Products can be mixed and matched from categories but must meet the minimum to proceed.

Better if the category selected can include subcategories.

This is NOT PER CATEGORY - PER PRODUCT, is combination requirement across, multiple products from multiple categories.

Can anyone help?

you need to customize and create a module as following : 

• create a module
• add an observer like below 
  

      <event name="sales_quote_item_qty_set_after">
          <observer name="inventory" instance="Magento\CatalogInventory\Observer\QuantityValidatorObserver"/>
      </event>

• here you can get the item and check qty as per your requirement
