Mostrare il prezzo consigliato (MSRP) in WooCommerce con WP-Lister for Amazon

Con il plugin WP-Lister for Amazon puoi impostare un prezzo consigliato (MSRP) per i prodotti. Questo però non compare come prezzo barrato quando inserisci un prezzo normale o scontato.

Aggiungi il codice qui sotto nel file functions.php e il prezzo normale mostrerà sempre il prezzo consigliato (MSRP), se impostato.

/**
Change on sale to true if MSRP is set, otherwise price only shows regular
**/
add_filter( 'woocommerce_product_is_on_sale', 'we_msrp_on_sale', 10, 1);
function we_msrp_on_sale($onsale) {
    global $product;
    if(!$product) {
        return $onsale;
    }
    $rrp = get_post_meta( $product->get_id(), '_msrp_price', true );
    if($rrp) {
        $price = $product->get_regular_price();
        $onsale = true;
    }
    $variable_rrp = get_post_meta( $product->get_id(), 'variable_msrp', true );
    if($variable_rrp) {
        $price = $variable_rrp;
        $onsale = true;
    }
    return $onsale;
}
/**
Sale price will be regular price if msrp is set
**/

    }
