WooCommerce ajax更新弄乱了价值观

Question

我目前正在与WooCommerce建立一个网上商店,我已经制作了这个购物车,您可以随时访问任何页面,您可以更新购物车内的产品数量.每当我这样做时,问题就会发生.例如,当我试图得到WC()->cart->total它返回0.

但是当我进入结账页面时,它显示了所有正确的购物车数据,所以这让我觉得我错过了一些action我必须在调整购物车中的东西后运行.我一直在寻找set_quantity()功能,它会自动刷新总数$this->calculate_totals();(手动尝试).

Ajax功能:

public function set_quantity($direction = false, $product_id) {
    $response = array();
    $justOne = false;

    if($_GET['data']['direction'] && $_GET['data']['product_id']) {
        $direction = $_GET['data']['direction'];
        $product_id = $_GET['data']['product_id'];
        $justOne = true;
    }

    foreach (WC()->cart->get_cart() as $cart_item_key => $values) {
        $_product = $values['data'];
        if ($product_id == $_product->id) {

            if($justOne && $direction == 'minus') {
                WC()->cart->set_quantity($cart_item_key, $values['quantity'] - 1, true);
                $response['success']['quantity'] = $values['quantity'] - 1;
            } else if($justOne && $direction == 'plus') {
                WC()->cart->set_quantity($cart_item_key, $values['quantity'] + 1, true);
                $response['success']['quantity'] = $values['quantity'] + 1;
            } else {
                WC()->cart->set_quantity($cart_item_key, $values['quantity'] + $direction, true);
            }

            $response['success']['line_total'] = '€ '.number_format((float)$response['success']['quantity'] * $_product->price, 2, '.', '');
            $response['success']['cart_count'] = WC()->cart->get_cart_contents_count();
            $response['success']['total'] = number_format((float)WC()->cart->total, 2, '.', '');
            die(json_encode($response));
        }
    }
    return false;
}

使用这个修改过的ajax函数。我已经测试过这个。它会起作用的。
