问题描述
我需要更新Cookie。我在一个php文件通过ajax调用。这是代码：
I need to update a cookie. I do that in a php file called via ajax. This is is the code:
setcookie('items['.$_POST['id'].']');
Cookie不会更新，实际上如果我写 print_r（$ _ COOKIE ['items']）在setcookie函数后，我看到 $ _ COOKIE ['items'] 是在调用setcookie功能。
The cookie does not update, in fact if I write print_r($_COOKIE['items']) after the setcookie function I see that $_COOKIE['items'] is the same that was before the call to setcookie function. How can I do?
推荐答案
您不能在同一个实例/页面中设置和访问cookie。
You cannot set and access a cookie in the same instance/page. You have to do a redirect or refresh after setting it.
此外，您应该这样做：
setcookie("id","items['.{$_POST['id']}.']");
