我使用Woocommerce插件在wordpress中开发了购物车。我需要按产品价格在购物车中显示产品，请帮我这样做

谢谢

Answer 1

mmmm，就在Woo管理页面上！

Woocommerce - ＆gt;调整 - ＆gt;目录 - ＆gt;默认产品订购

Answer 2

要在Woocommerce购物车中订购价格从低到高或从高到低的产品，请尝试将以下内容添加到您的functions.php文件（或插件）中：

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' );

此功能与https://businessbloomer.com/woocommerce-sort-cart-items-alphabetically-az/相似，该功能与之前发布的功能https://gist.github.com/maxrice/6541634

几乎相同

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

另外，WC_car.cart_contents数组，在$cart_contents['data']; //WC_Product_Object上保存了它自己的product对象，所以我们不需要再次获取product。

按价格排序的简单过滤器：

PHP 7.4+

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;
}

PHP < 7

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;
}
