Explanation

If you're looking to make your WooCommerce prices look cleaner by rounding them up to the nearest whole number, this code snippet does just that. Here's how it works:

Price Rounding: The code uses a function to check if the price is a number. If it is, it rounds it up to the nearest whole number using a method called ceil.
Where It Applies: This rounding is applied to regular prices, sale prices, cart item prices, and order item prices. So, whether a customer is browsing your store, checking their cart, or reviewing their order, they'll see rounded prices.
Integration with WooCommerce: The code hooks into WooCommerce's pricing system using filters. This means it automatically adjusts prices without needing manual updates for each product.

By using this code, you ensure that all displayed prices are neat and rounded, which can enhance the shopping experience by making prices easier to read and understand.

Code
<?php
// Function to round up WooCommerce prices to the nearest whole number
function wp_dudecom_round_woocommerce_prices( $price, $product ) {
    // Check if the price is a valid number
    if ( is_numeric( $price ) ) {
        // Round the price to the nearest whole number
        $price = ceil( $price );
    }
    return $price;
}

// Hook the function to WooCommerce price filters
add_filter( 'woocommerce_get_price', 'wp_dudecom_round_woocommerce_prices', 10, 2 );
add_filter( 'woocommerce_get_sale_price', 'wp_dudecom_round_woocommerce_prices', 10, 2 );
add_filter( 'woocommerce_get_regular_price', 'wp_dudecom_round_woocommerce_prices', 10, 2 );

// Function to round up WooCommerce cart item prices to the nearest whole number
function wp_dudecom_round_cart_item_prices( $price, $cart_item, $cart_item_key ) {
    // Check if the price is a valid number
    if ( is_numeric( $price ) ) {
        // Round the price to the nearest whole number
        $price = ceil( $price );
    }
    return $price;
}

// Hook the function to WooCommerce cart item price filter
add_filter( 'woocommerce_cart_item_price', 'wp_dudecom_round_cart_item_prices', 10, 3 );

// Function to round up WooCommerce order item prices to the nearest whole number
function wp_dudecom_round_order_item_prices( $price, $order_item ) {
    // Check if the price is a valid number
    if ( is_numeric( $price ) ) {
        // Round the price to the nearest whole number
        $price = ceil( $price );
    }
    return $price;
}

// Hook the function to WooCommerce order item price filter
add_filter( 'woocommerce_order_item_get_total', 'wp_dudecom_round_order_item_prices', 10, 2 );
?>
