问题描述
我在laravel 5.4中具有此功能,但出现错误.
I have this function in laravel 5.4 but I get error.
$cart[$product->id] = $quantity;
var_dump($cart);
return redirect('catalogs')->withCookie(cookie()->forever('cart', $cart));
var_dump($ cart)包含以下内容:
var_dump($cart) contains this:
array(1) { [1]=> string(1) "1" }
错误警告:
Method Symfony\Component\HttpFoundation\Cookie::__toString() must not throw an exception, caught ErrorException: Array to string conversion
如果仅传递字符串值(而不是数组),则成功.是否有任何方法可以在Laravel中存储数组cookie?
If I passed just string value (not array), it success. If there any way to store array cookie in Laravel?
谢谢.
推荐答案
cookie中只能存储字符串.所以试试这个:
Only strings can be stored in a cookie. So try this:
$cart[$product->id] = $quantity;
var_dump($cart);
return redirect('catalogs')->withCookie(cookie()->forever('cart', serialize($cart)));
