Answer 1

在大多数情况下，对于操作WordPress生态系统上的数据，答案将是wp filter，没有wp action。

此外，WC\u车。cart_contents数组，将产品对象保持在其自身上$cart_contents['data']//WC_Product_对象，因此我们不需要再次获取产品。

add_filter( 'woocommerce_get_cart_contents', 'prefix_cart_items_order' );
function prefix_cart_items_order( $cart_contents ) {
  uasort($cart_contents, 
         fn($a, $b) => 
             $a['data']->get_price() < $b['data']->get_price() ? -1 : 1
  );
  return $cart_contents;
}

add_filter( 'woocommerce_get_cart_contents', 'prefix_cart_items_order' );
function prefix_cmp ($a, $b) { 
  return $a['data']->get_price() < $b['data']->get_price() ? -1 : 1;
}
function prefix_cart_items_order( $cart_contents ) {
  uasort($cart_contents, 'prefix_cmp');
  return $cart_contents;
}

要在Woocommerce购物车中以从低到高或从高到低的价格订购产品，请尝试在功能中添加以下内容。php文件（或插件）：

function 12345_cart_updated() {

    $products_in_cart = array();
    // Assign each product's price to its cart item key (to be used again later)
    foreach ( WC()->cart->cart_contents as $key => $item ) {
        $product = wc_get_product( $item['product_id'] );
        $products_in_cart[ $key ] = $product->get_price();
    }

    // SORTING - use one or the other two following lines:
    asort( $products_in_cart ); // sort low to high
    // arsort( $products_in_cart ); // sort high to low

    // Put sorted items back in cart
    $cart_contents = array();
    foreach ( $products_in_cart as $cart_key => $price ) {
       $cart_contents[ $cart_key ] = WC()->cart->cart_contents[ $cart_key ];
    }

    WC()->cart->cart_contents = $cart_contents;

}
add_action( 'woocommerce_cart_loaded_from_session', '12345_cart_updated' );

该函数类似于https://businessbloomer.com/woocommerce-sort-cart-items-alphabetically-az/中的一个函数，该函数与之前发布的函数几乎相同：https://gist.github.com/maxrice/6541634
