如何在Laravel 5.4中存储数组cookie? [英] How to store array cookie in laravel 5.4?

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)));
