WooCommerce - Disable ALL sale prices with code

functions.php

<?php 

/**
 * After adding this code to theme functions.php, ensure you clear transients via WC > System Status > Tools
 */
add_filter( 'woocommerce_get_sale_price', '__return_empty_string' );
add_filter( 'woocommerce_variation_prices_sale_price', '__return_empty_string' );

add_filter( 'woocommerce_variation_prices_price', 'custom_get_price', 10, 2 );
add_filter( 'woocommerce_get_price', 'custom_get_price', 10, 2 );

function custom_get_price( $price, $product ) {
	if ( $product->is_type( 'variable' ) ) {
		 $prices = $product->get_variation_prices();
		 return min( $prices['regular_price'] );
	} else {
		return $product->get_regular_price();
	}
}

Hi,
Do you know a way to hide the sale price on the single product page only?

Hi, the code does not work in the cart, how can I disable it in the whole store?
