Ok, we’re in a niche of a niche this time – manual orders (orders created by the WooCommerce administrator). If you’re familiar with that, the admin would click on “Add order“, fill out the billing & shipping information, and then move to the order items section, where they can add products to the order.
As soon as they click on “Add items” > “Add products“, a table displays with a product search and quantity input. That’s exactly where we’re working today: what if you have 10,000 products in your store, but only create manual invoices with the same 2-3 products? In this case scenario, it makes no sense to search for the whole 10,000 product list and wait for WooCommerce to return a result (slowly) – it’s much more efficient to reduce that list to a specific category or a list of IDs so that the search operations can be faster.
Here’s how it’s done. Enjoy!Continue reading WooCommerce: Alter Product Search @ Manual Admin Orders
