购物车在电商场景中基本是必须的一个模块

安装

composer require yzh52521/webman-shop-cart

用法

选择 Storage

您可以更改数据存储在 config/plugin/yzh52521/shop-cart/app.php 配置文件.

session

'storage' => \yzh52521\ShopCart\storage\SessionStorage::class,

datadate 

'storage' => \yzh52521\ShopCart\storage\DatabaseStorage::class,  //tp-orm
or
'storage' => \yzh52521\ShopCart\storage\LaravelDatabaseStorage::class, // laravel

如果更改数据存储如果使用数据库存储，则需要创建数据表：

CREATE TABLE `shopping_cart`
(
    `key`         varchar(255) CHARACTER SET utf8 NOT NULL,
    `__raw_id`    varchar(255) CHARACTER SET utf8 NOT NULL,
    `guard`       varchar(255) CHARACTER SET utf8          DEFAULT NULL,
    `user_id`     int                                      DEFAULT NULL,
    `id`          int                             NOT NULL,
    `name`        varchar(255) CHARACTER SET utf8 NOT NULL,
    `qty`         int                             NOT NULL,
    `price`       decimal(8, 2)                   NOT NULL,
    `total`       decimal(8, 2)                   NOT NULL,
    `__model`     varchar(255) CHARACTER SET utf8          DEFAULT NULL,
    `type`        varchar(255) CHARACTER SET utf8          DEFAULT NULL,
    `status`      varchar(255) CHARACTER SET utf8          DEFAULT NULL,
    `attributes`  text CHARACTER SET utf8,
    `create_time` timestamp                       NOT NULL DEFAULT CURRENT_TIMESTAMP,
    `update_time` timestamp NULL DEFAULT NULL,
    PRIMARY KEY (`key`, `__raw_id`)
