WooCommerce: Set Min Purchase Amount for Specific Product

We already studied how to set min/max WooCommerce add to cart quantity programmatically. That was an easy one. This time, I want to expand on the topic, and define a “minimum order amount on a per-product basis”.

Which, translated in plain English, would be something along the lines of “set the minimum purchase amount for product XYZ to $50”. And once we do that, I expect that the add to cart quantity does non start from 1 – instead it defaults to “$50 divided by product price”. If product price is $10, I would want to set the minimum add to cart quantity to “5” on the single product and cart pages.

Makes sense? Great – here’s how it’s done.

In this example, if I want to force $50 as minimum purchase amount, the product add to cart quantity will start from 5 and not 1.

PHP Snippet: Set Min Add to Cart Quantity for Specific Product Based on Min Amount Purchase @ WooCommerce Single Product & Cart Pages

In the example below, I’m setting a minimum purchase amount for product ID = 123 of $50. This function will need to act on the single product page and cart page. If product ID = 123 price is $9, the $min amount will be: ceil(50/9) = 6

add_filter( 'woocommerce_cart_item_quantity', 'bloomer_woocommerce_quantity_min_50_eur_cart', 9999, 3 );
  
function bloomer_woocommerce_quantity_min_50_eur_cart( $product_quantity, $cart_item_key, $cart_item ) {  
	
	$_product = apply_filters( 'woocommerce_cart_item_product', $cart_item['data'], $cart_item, $cart_item_key );
	
	$min = 0;

	if ( 123 === $product->get_id() ) {
		$min = ceil( 50 / $_product->get_price() );
	}
	
	$product_quantity = woocommerce_quantity_input( array(
		'input_name'   => "cart[{$cart_item_key}][qty]",
		'input_value'  => $cart_item['quantity'],
		'max_value'    => $_product->get_max_purchase_quantity(),
		'min_value'    => $min,
		'product_name' => $_product->get_name(),
	), $_product, false );
	
	return $product_quantity;

Where to add this snippet?

You can place PHP snippets at the bottom of your child theme functions.php file (before "?>" if you have it). CSS, on the other hand, goes in your child theme 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 free video tutorial "Where to Place WooCommerce Customization?"

Does this snippet (still) work?

Please let me know in the comments if everything worked 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 on PHP 7+.

  1. Hi Rodolfo.
    Thank you for your snippet.
    But unfortunately, this snippet is not working on cart page.
    can you please revise the code and update?
    Thanks

    1. Hi there, works for me. Can you try with a default theme and no other plugins than Woo?

  2. So I guess that you prefer this method over the min-max plugin that is out there, especially if you only need it for a couple of products?
    I have the plugin installed and I’m using it. Would my installation work better if I get rid of the plugin and use this snippet instead?

    1. Yes, I guess that’s my idea re: quick and easy snippets vs complex plugins ๐Ÿ™‚
