wp wc php remove product from cart if amount is 0
You can use the following code to remove a product from the cart if the amount is 0 in WordPress/WooCommerce:
add_action( 'woocommerce_before_calculate_totals', 'remove_product_from_cart_if_amount_zero' );
function remove_product_from_cart_if_amount_zero( $cart ) {
foreach ( $cart->get_cart() as $cart_item_key => $cart_item ) {
if ( $cart_item['quantity'] == 0 ) {
$cart->remove_cart_item( $cart_item_key );
}
}
}
Explanation:
1. We use the woocommerce_before_calculate_totals
action hook to call the remove_product_from_cart_if_amount_zero
function before calculating the cart totals.
2. Inside the remove_product_from_cart_if_amount_zero
function, we iterate through each item in the cart using a foreach loop.
3. We then check if the quantity of the cart item is 0, and if so, we use the remove_cart_item
method to remove the item from the cart.
Remember to test this code thoroughly before implementing it on a live site.
