php - 如何从会话 Laravel 中删除项目

问题描述

如何从 laravel 的会话中删除数据。我不想通过单击单个删除按钮来删除所有数据。我对每个数据都有删除按钮，所以想一一删除。我当前的代码如下：

public function deleteProduct(Request $request){
    $id = $request->productId;// this id i want to delete which i get from view
    $products = $request->session()->get('product');

    foreach ($products as $key => $value)
    {
        if ($value['id'] == $id)
        {
            unset($products [$key]);
        }
    }

    //then you can redirect or whatever you need
    return redirect()->back();
}

我也试过这个

foreach ($products as $product)
{
    if ($product->id == $id)
    {
        $products->forget($product);
    }
}

我在会话中的数据格式如下

[
{
id: 2,
name: "Marlene Reichert",
description: "Debitis asperiores sed sit assumenda unde quo natus. Consequatur est labore tenetur quae. Eius distinctio ea omnis aspernatur porro earum quae.",
category_id: 3,
price: 76,

created_at: "2019-07-16 10:12:27",
updated_at: "2019-07-16 10:12:27",
qty: 1
},
{
id: 6,
name: "Kaylin Emard",
description: "Et aperiam omnis nam iure id non fugiat. Excepturi voluptatem ipsam magnam. Esse asperiores ducimus enim et.",
category_id: 8,

created_at: "2019-07-16 10:12:27",
updated_at: "2019-07-16 10:12:27",
qty: 1
},
{
id: 5,
name: "Prof. Iliana Mohr",
description: "Autem sequi esse laudantium ut ut explicabo enim. Corporis cupiditate dolorum et ratione sequi architecto. Vitae enim ex hic nihil.",
category_id: 2,
price: 207,
image: "http://loremflickr.com/400/300?random=99",
created_at: "2019-07-16 10:12:27",
updated_at: "2019-07-16 10:12:27",
qty: 1
}
]

在我的网络选项卡中，单击删除按钮时出现以下错误

{message: "Invalid argument supplied for foreach()", exception: "ErrorException",…}
exception: "ErrorException"
file: "/Applications/XAMPP/xamppfiles/htdocs/fresh/app/Http/Controllers/ProductController.php"
line: 33
message: "Invalid argument supplied for foreach()"
trace: [{file: "/Applications/XAMPP/xamppfiles/htdocs/fresh/app/Http/Controllers/ProductController.php",…},…]
0: {file: "/Applications/XAMPP/xamppfiles/htdocs/fresh/app/Http/Controllers/ProductController.php",…}
1: {function: "deleteProduct", class: "App\Http\Controllers\ProductController", type: "->"}
2: {,…}

在 dd()

$id = $request->productId;
    $products = $request->session()->get('product');
    dd($products);

在我的网络标签中，我得到了这个

array:1 [
  0 => {#216
    +"id": 1
    +"name": "Keyshawn McDermott Sr."
    +"description": "Error aut quia id dolorem est aut doloribus nesciunt. Quod nihil tenetur ea id voluptas molestias id. Debitis amet dolor est fugiat sed autem."
    +"category_id": 1
    +"price": 59
    +"image": "http://loremflickr.com/400/300?random=36"
    +"created_at": "2019-07-16 10:12:27"
    +"updated_at": "2019-07-16 10:12:27"
    +"qty": 1
  }
]
