It’s not uncommon to be asked to implement minimum checkout requirements to WooCommerce Cart. The common requirements are:
- Minimum Dollar Amount Per Order
- Minimum Number of Products Per Order or Per Products
Luckily, there is a great tutorial for implementing these by Yojance Rabelo.
But the other day, I got a request to implement minimum dollar amount PER PRODUCT…not too common, but not never-heard-of either.
So I decided to tweak Yojance’s Minimum Dollar Per Order code to set minimum order amount for a product instead of for the entire order:
Here is the code. You want to add this in functions.php
/*
* Minimum Order Dollar Amount for a specific product
* In this example, the product's subtotal must be $100 or more
*/
add_action( 'woocommerce_check_cart_items', 'product_set_min_total' );
function product_set_min_total() {
// Only run in the Cart or Checkout pages
if( is_cart() || is_checkout() ) {
global $woocommerce;
// Set minimum product total
$minimum_cart_total = 100;
// Total we are going to be using for the Math
// This is before taxes and shipping charges
$total = 0;
//foreach products in the cart ()
foreach ( WC()->cart->get_cart() as $cart_item_key => $cart_item ) {
$_product = apply_filters( 'woocommerce_cart_item_product', $cart_item['data'], $cart_item, $cart_item_key );
//this example's product id = 3288
$product_id = apply_filters( 'woocommerce_cart_item_product_id', $cart_item['product_id'], $cart_item, $cart_item_key );
if (strcmp($cart_item['product_id'], "3288") == 0 ) {
$subtotal = $_product->get_price() * (float)$cart_item['quantity'];
$total = $total + $subtotal;
}
}
// Will display a message along the lines of
// A Minimum of 100 USD is required before checking out. (Cont. below)
if( $total <= $minimum_cart_total ) {
// Display our error message
wc_add_notice(
sprintf(
'<strong>A Minimum subtotal of $%s %s is required for Sample Product before checking out.</strong>'.'<br />Current cart\'s total: $%s %s',
$minimum_cart_total,
get_option( 'woocommerce_currency'),
$total,
get_option( 'woocommerce_currency')
),
'error'
);
}
}
