WooCommerce: Alter Product Search @ Manual Admin Orders

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!

With the snippet below, I’ve reduced the possible search results to… 2 products only, by simply defining an array of product IDs.

add_filter( 'woocommerce_product_pre_search_products', 'bbloomer_only_search_these_products', 9999, 6 );

function bbloomer_only_search_these_products( $custom_query, $term, $type, $include_variations, $all_statuses, $limit ) {
	if ( ! isset( $_GET['exclude_type'] ) ) return $custom_query; 
	// we should be on the order admin page now	
	$product_ids = array( 21230, 21231 );
	return $product_ids;
}

Where to add custom code?

You should place PHP snippets at the bottom of your child theme functions.php file and CSS at the bottom of its style.css file. Make sure you know what you are doing when editing such files - if you need more guidance, please take a look at my guide "Should I Add Custom Code Via WP Editor, FTP or Code Snippets?" and my video tutorial "Where to Place WooCommerce Customization?"

Does this snippet (still) work?

Please let me know in the comments if everything went as expected. I would be happy to revise the snippet if you report otherwise (please provide screenshots). I have tested this code with Storefront theme, the WooCommerce version listed above and a WordPress-friendly hosting.
