php - Cookie 在 PHP 中不起作用，但在 Javascript 中起作用

Question

我需要查看产品购物车，并且需要通过 PHP 进行首次加载，并通过 jQuery post 进行其余查询(通过删除产品或类似内容进行更新)。

好吧，问题来了。

[我在同一个 php 文件“any.php”上通过 JSON 获取变量]

当我在 PHP 上执行第一个 isset($_COOKIE) (通过curl)并返回 NULL 时，第一个 PHP 加载不起作用，但是..如果我调用该方法 .post("any.php") 在 jQuery PHP 上，它返回包含产品的购物车。

为了添加产品，我使用 PHP 函数

setcookie($cookieName, $createcart, $cookieExpire);

Cookie 参数:

session_set_cookie_params(
    time()+3600,
    '/',
    '.test.com',
    0,
    0
);

setCookie(createcart为json值):

setcookie($cookieName, $createcart, $cookieExpire);

Common Pitfalls:

Cookies will not become visible until the next loading of a page that the cookie should be visible for. To test if a cookie was successfully set, check for the cookie on a next loading page before the cookie expires. Expire time is set via the expire parameter. A nice way to debug the existence of cookies is by simply calling print_r($_COOKIE);.
