Woocomerce Minimum Required Items

That looks like that may work, thank you, Mike Jolley!

Before I test it out do you know if I add multiple items to the dependency? For example, product A can only be added onto the cart if a minimum of products from X, Y, Z are in the cart?

So I have to have 10 X’s or 5 X’s and 5 Y’s in the cart before I can add product A.

I tried using the plug in and it would be great if it was just one product. I’ll have to use a woocommerce filter that requires a buyer to have X amount of category B if item C is in the cart.

I’ll have to do more research on it. Does anyone know how to write a filter or hook to do that?

I’ve tried using this code:

//
/**
 * Renders notices and prevents checkout if the cart
 * does not contain a minimum number of products in a category
 */
function sww_check_category_for_minimum() {
	// set the minimum quantity in the category to purchase
	$min_quantity = 1;
	// set the id of the category for which we're requiring a minimum quantity
	$category_id = 90;
	// get the product category
	$product_cat = get_term( $category_id, 'product_cat' );
	$category_name = '<a href="' . get_term_link( $category_id, 'product_cat' ) . '">' . $product_cat->name . '</a>';
	// get the quantity category in the cart
	$category_quantity = sww_get_category_quantity_in_cart( $category_id );
	if ( $category_quantity < $min_quantity ) {
		// render a notice to explain the minimum
		wc_add_notice( sprintf( '<strong>A minimum quantity of the choosen Brewer has not been met. <br /> (Kuerig 140 Reqiures A Minimum of 4 Boxes to Order)<br />(Kuerig 150 Reqiures A Minimum of 8 Boxes to Order)<br />(Kuerig K3000SE Reqiures A Minimum of 12 Boxes to Order)<br />(Kuerig Bolt Carafe Reqiures A Minimum of 10 Boxes to Order)</strong><br />'), 'error' );
	}
}
add_action( 'woocommerce_check_cart_items', 'sww_check_category_for_minimum' );
/**
 * Returns the quantity of products from a given category in the WC cart
 *
 * @param int $category_id the ID of the product category
 * @return in $category_quantity the quantity of products in the cart belonging to this category
 */
function sww_get_category_quantity_in_cart( $category_id ) {
	// get the quantities of cart items to check against
	$quantities = WC()->cart->get_cart_item_quantities();

	// start a counter for the quantity of items from this category
	$category_quantity = 0;
	// loop through cart items to check the product categories
	foreach ( $quantities as $product_id => $quantity ) {
		$product_categories = get_the_terms( $product_id, 'product_cat' );

		// check the categories for our desired one
		foreach ( $product_categories as $category ) {
			// if we find it, add the line item quantity to the category total
			if ( $category_id === $category->term_id ) {
				$category_quantity += $quantity;
			}
		}
	}
	return $category_quantity;
}

The code displays on the cart page and prevents you from checking out even if you have the right product categories. I do not know how to check to see if the right product ID is in the cart for the function to run and display the error.
