Question

我想给购物车对象一个新的ID，我有以下代码：

SELECT DISTINCT --Does this need to be here?
       h.id,
       h.status,
       a.billing_state,
       d.queue_desc,
       r.role_desc,
       DATEDIFF(DAY, recd_dt, GETDATE() + 1) AS AGE,
       h.drag_dt
FROM dbo.tbl_1 h
     JOIN dbo.prov p ON h.id = p.id
     JOIN dbo.address a ON p.id = a.id
     LEFT JOIN dbo.queue_msg m ON h.id = m.msg_id
     LEFT JOIN dbo.queue_def d ON m.queue_id = d.queue_id
     LEFT JOIN dbo.roles r ON m.role_id = r.role_id
     JOIN dbo.me_msg w ON h.ck = w.ck
WHERE h.ck = '123'
  AND a.type = 'PRI'
  AND w.seq_no = '00000'
  AND (((h.drag_dt BETWEEN '9999-01-01 00:00:00.000' AND '9999-12-31 00:00:00.000'
      OR h.drag_dt BETWEEN '3334-01-01 00:00:00.000' AND '3334-12-31 00:00:00.000')
    AND h.status = '04')
    OR (NOT (h.drag_dt BETWEEN '9999-01-01 00:00:00.000' AND '9999-12-31 00:00:00.000'
          OR h.drag_dt BETWEEN '3334-01-01 00:00:00.000' AND '3334-12-31 00:00:00.000')
    AND h.status IN ('01', '02', '03')))
ORDER BY h.drag_dt DESC;

未“替换”购物车，我尝试了几件事：使用$ GLOBALS全局关键字，但是没有什么能真正替换或更改购物车对象。最好的方法是什么？

尝试：

if ($payment->order_result->return->failures->failure == 'field.ordernumber.exists') {
    $context = Context::getContext();
    $cart_products = $context->cart->getProducts();
    $this->context->cart->delete();    
    $newCart = new Cart();

    if (!$context->cart->id) {
        $guest = new Guest();
        $context->cart->mobile_theme = $guest->mobile_theme;

        $context->cart->add();
        if ($context->cart->id)
            $context->cookie->id_cart = (int)$context->cart->id;
    }

    foreach ($cart_products as $product) {
        Db::getInstance()->insert('cart_product', array(
                    'id_product' =>             (int)$product->id,
                    'id_product_attribute' =>   (int)0,
                    'id_cart' =>                (int)$newCart->id,
                    'quantity' =>               (int)$product->quantity,
                    'date_add' =>               date('Y-m-d H:i:s')
                ));
    }    
}

受@ethercreation答案的启发，我更改了以下内容以解决我的问题：

import numpy as np
import cv2
from matplotlib import pyplot as plt

img1 = cv2.imread('template.jpg',0)          # queryImage
img2 = cv2.imread('input.jpg',0) # trainImage

sift=cv2.xfeatures2d.SIFT_create()

kp1, des1 = sift.detectAndCompute(img1,None)
kp2, des2 = sift.detectAndCompute(img2,None)

# BFMatcher with default params
bf = cv2.BFMatcher()
matches = bf.knnMatch(des1,des2, k=2)

# Apply ratio test
good = []
for m,n in matches:
    if m.distance < 0.75*n.distance:
        good.append([m])

# cv2.drawMatchesKnn expects list of lists as matches.
img3 = cv2.drawMatchesKnn(img1,kp1,img2,kp2,good,None,flags=2)

$dup = $this->context->cart->duplicate();
$this->context->cart->delete();
$this->context->cart = new Cart($dup['cart']->id);

必不可少的部分是$dup = $this->context->cart->duplicate(); $this->context->cart->delete(); $this->context->cookie->id_cart = $dup['cart']->id;无法更改。需要复制购物车，然后更改cookie中的当前购物车。因此，应将Cookie $this->context->cart更改为新创建的购物车的$this->context->cookie->id_cart！

将购物车复制到另一个购物车中以更改id_cart
