使用多个不同的按钮在购物车中添加多个项目（添加到购物车）
[英]Adding Multiple Items in Cart (add to cart) using multiple different buttons
问题描述
我是初学者。 我正在开发一个电子商务网站。 我的问题是我似乎无法在购物车中添加多个项目。 如果我单击了某个项目，它将被添加到购物车，但是当我单击另一个项目时，它将仅替换我选择的第一个项目。 关于如何解决该问题的任何建议？ 谢谢

您正在使用原始会话变量： $_SESSION['prod_id'] ，它应该是一个数组。
像这样初始化它：
$_SESSION['prod_ids'] = [];
然后，在将产品添加/删除到购物车后，更新$_SESSION['prod_ids']
array_push($_SESSION['prod_ids'],/*product_id*/)

您应该考虑执行以下操作：
如果产品是当前产品，则将隐藏字段添加到包含产品ID的HTML中。
<p>Price: 9,199 Php<br>
<input class="btn btn-success" type="submit" name="action" value="add_to_cart">
<input type="hidden" name="product_id" value="1">
<span class="glyphicon glyphicon-shopping-cart"></span>
</p>
然后，您可以将PHP重构为此
<?php
if (session_status() == PHP_SESSION_NONE) {
session_start();
$_SESSION['cart'] = array();
}
$connection = mysql_connect("localhost", "root", "");
if(isset($_GET['add_to_cart'])){
array_push($_SESSION['cart'], $_GET['product_id'];
header("location: ../" . $_GET['product_id'] . ".php");
}
mysql_close($connection);
请注意，在创建会话对象时，如何将$_SESSION['cart']初始化为数组。 无需将产品ID分配给$_SESSION['cart'] ，您可以将其推入数组。
重构您在标头中设置的php文件的名称，或添加一个包含文件名称的其他隐藏字段。

如果您有1000个要添加到购物车的商品，则不能编写if if语句。更好地使用循环。我为要创建的代码创建了示例代码，并使用自己的逻辑创建了所需的代码。
