Laravel在会话中存储数组 [英] Laravel Store Array in Session

问题描述

我在会话中存储数组时遇到了麻烦.我在做购物车，但似乎不起作用.

I have been having trouble storing an array in session. I am making a shopping cart and it doesn't seem to work.

public function __construct(){

  $product = array(1,2,3,4);
  Session::push('cart', $product);

}

，然后在这样的视图中检索它.

and then retrieve it in the view like this.

{{Session::get('cart')}}

但是我一直收到这样的错误.

However I keep getting an error like this.

htmlentities() expects parameter 1 to be string, array given

关于如何创建存储一系列商品的购物车的任何线索和建议.

Any clues and advice on how to create a shopping cart that stores an array of items.

推荐答案

如果您需要使用session中的数组作为字符串，则需要使用Collection，如下所示:

If you need to use the array from session as a string, you need to use Collection like this:

$product = collect([1,2,3,4]);
Session::push('cart', $product);

当您在html中使用{{Session::get('cart');}}时，这将使其起作用.请注意Session::push，因为它将始终在会话中附加新产品.您应该使用Session::put来确保产品将始终处于更新状态.

This will make it work when you will be using {{Session::get('cart');}} in your htmls. Be aware of Session::push because it will append always the new products in sessions. You should be using Session::put to be sure the products will be always updating.
