WooCommerce cookies和会话 - 获取当前产品的购物车 [英] WooCommerce cookies and sessions - Get the current products in cart
问题描述
我尝试学习WooCommerce的cookies,用于执行添加到购物车中的产品操作的任何功能。我在控制台中写道 document.cookie
我得到这些数据:
I try to learn the cookies of WooCommerce, for do any function operating by products the added to cart. I wrote in console document.cookie
And I get this data:
woocommerce_items_in_cart=1;
woocommerce_cart_hash=500d17f6c010b62b25c3f52893be945d;
我知道cookie woocommerce_cart_hash
包含购物车中的产品,但我不明白如何获得产品的名称。这是什么 500d17f6c010b62b25c3f52893be945d
I understand that the cookie "woocommerce_cart_hash
" contains the products in cart, but I don't understand how to get the name of the product. What is it 500d17f6c010b62b25c3f52893be945d
任何帮助都将不胜感激。
Any help would be appreciated.
推荐答案
正如您将在下面看到的, woocommerce_cart_hash
不包含购物车中的产品,因为与 WooCommerce会话数据库表相关的第三个更复杂的coockie 。
As you will see below, woocommerce_cart_hash
doesn't contains the products in cart, because there is a third more complex coockie related to WooCommerce sessions DB table.
数据不会存储在Cookie中,而是存储在DB WooCommerce会话中的相应参考中(详见下文) ...
The data is not stored in the cookie herself but in a corresponding reference located in DB WooCommerce session (see below for details)...
您还需要注意,WordPress会启用一些本地数据存储。
You have also to note that WordPress enable some local data storage.
以下数据来自一个真实的案例,非登录用户将2个产品添加到购物车。
1)当非登录用户向购物车添加内容时,Woocommerce设置3个coockies:
1) Woocommerce set 3 coockies when a non logged user add something to cart:
woocommerce_cart_hash
=>44ffcb32800e5b20cfbb080753d48408
(安全/完整性哈希)
woocommerce_items_in_cart
=>1
(设为1
什么东西在购物车中)

(与wp_woocommerce_sessions
完全相关的DB表创建的会话与此cookie同时进行)
woocommerce_cart_hash
=>44ffcb32800e5b20cfbb080753d48408
(security/integrity hash)woocommerce_items_in_cart

(completely related towp_woocommerce_sessions
DB table created session at the same time than this cookie)
2)在数据库表中 wp_woocommerce_sessions
会话同时生成:
2) And in DB table wp_woocommerce_sessions
a session is generated at the same time:

我无法解释所有核心流程(为此你将需要查看php核心文件)。
但是如果你想看 wp_woocommerce_session_ ...
cookie值,你会看到你可以用%7C%7C
substring,所以我们得到这个cookie值的4个子串:
I can't explain all core processes (for that you will need to look in php core files).
But if you look to wp_woocommerce_session_…
cookie value you will see that you can cut it with %7C%7C
substring, so we get here 4 substrings for this cookie value:
ac5f880c99503169574ad996f35f85c5
(数据库中的相同参考session_key
和表wp_woocommerce_sessions
)的session_value
。
1469492696
(表 <$ c>的数据库session_expiry
$ c> wp_woocommerce_sessions )。
1469489096
(同上) 。

(same thing above).17e565032403642121f5ad12cfa72c41
(??? - I don't really know what is this for…)
如果用户回来并删除他的一项购物车:
If the user come back and delete one item in his cart:
-
woocommerce_cart_hash
cookie 价值变动 -
woocommerce_items_in_cart
Cookie 值不会随着商品保留在购物车中而发生变化。 -
wp_woocommerce_session_3413758cad2ada414127ffee7347e40f
Cookie 值不会发生变化。 - 数据库
wp_woocommerce_sessions
表,会话ID <$ c6 已被新生成的会话ID 删除/替换购物车更改(仅限一种产品)。
woocommerce_cart_hash
cookie value changeswoocommerce_items_in_cart
cookie value don't changes as an item remains in cart.wp_woocommerce_session_3413758cad2ada414127ffee7347e40f
cookie value don't changes.- DB
wp_woocommerce_sessions
TABLE, the session ID6
has been deleted/replaced by a new generated session ID is that reflects the cart changes (only one product).
因此,此时您可以看到Cookie和会话数据库表
wp_woocommerce_sessions
之间的关系,其中包含与未登录用户相关的所有购物车数据
(在session_value
序列化多维数组或对象中)
So at this point you can see the relation between cookies and session DB table
wp_woocommerce_sessions
that contains all cart data related to non logged users
(in asession_value
serialized multidimensional array or object).
使用 类WC_Cart 您将能够获得此数据。
您还应该能够在PHP代码中使用 WC() - > cart
语法...
使用 Class WC_Session_Handler ,您将能够自己操纵会话。
With Class WC_Session_Handler you will be able to manipulate sessions herself.
要完成,请 类WC_Ajax 用于购物车更改。
And to finish, Class WC_Ajax is used for cart changes.
