Allow customer to purchase only one item - WooCommerce
In one of my recent WooCommerce project, I want to allow user to purchase only one item ( any one, but only one product ) from my shop!
To achive this functionalitty, we want to add a small code snippet in our theme’s / child theme’s functions.php
file.
add_filter( 'woocommerce_add_cart_item_data', 'woo_allow_one_item_only' );
function woo_allow_one_item_only( $cart_item_data ) {
global $woocommerce;
$woocommerce->cart->empty_cart();
// Do nothing with the data and return
return $cart_item_data;
}
The above code snippet is a filter function that will work on woocommerce_add_cart_item_data
filter hook. When we add a new product in to cart, our function become triggered and it will empty current cart items.
