If you want customers to purchase only one quantity of each product, you can remove the quantity field from the WooCommerce Cart page.
Steps
- Open your theme’s
functions.phpfile. - Add the code below.
- Save the file.
- Refresh your Cart page.
Done — the quantity input will be hidden from the cart.
function hide_cart_quantity_field( $product_quantity, $cart_item_key, $cart_item ) {
return '<span class="cart-quantity">1</span>';
}
add_filter(
'woocommerce_cart_item_quantity',
'hide_cart_quantity_field',
10,
3
);
