Woocommerce Mini Cart Widget product price override

问题

is it possible to change product price in Woocommerce Mini Cart Widget? I've overrided price in cart using tips from WooCommerce: Add product to cart with price override? but it only works for cart page. Prices in widget are not changed.

回答1:

This is how I set price to 0 for free products:

function set_free_items_price( $price, $cart_item, $cart_item_key ) {

     $returned_item_price = $cart_item['data']->get_price();

     if (isset($cart_item['free_item']['value'])
         && $cart_item['free_item']['value'] == true) {
         $returned_item_price = 0;
     }

     return get_woocommerce_currency_symbol() . $returned_item_price;
}

I hooked inside class, so it hook looks like this:

add_filter( 'set_free_items_price', array(__CLASS__, 'woocommerce_cart_item_price_filter'), 10, 3 );

But if you are using it as procedural function, your hook should look like this:

add_filter( 'set_free_items_price', 'woocommerce_cart_item_price_filter', 10, 3 );

Keep in mind this is also affecting price row in regular cart. And, if you are not seeing changes in mini cart, try to update cart on regular cart page, and the go back and check again if mini-cart values has been changed.

Instead of using "woocommerce_before_calculate_totals" you can use "woocommerce_cart_item_price" filter, some thing like

add_filter('woocommerce_cart_item_price','modify_cart_product_price',10,3);

function modify_cart_product_price( $price, $cart_item, $cart_item_key){
    $price = wc_price($custom_price, 4); 
    return $price;
}
