因此,我设置了我的购物车,以使用GET功能接收有关添加的每个项目的特定信息。但是,在读取数据库的实现中,如果添加另一个项目,这些值将会变得相同。 如果我添加椅子1,然后再次椅子1,它增加了椅子1的总数,说有2椅子1的。但是,如果我再添加椅子2,则会有一个新的条目,但具有所有椅子的价值。PHP购物车阵列
阵列输出
Array ([0] => Array ([item_id] => 2 [quantity] => 1) [1] => Array ([item_id] => 4 [quantity] => 7))

数据库:
<?php
include_once('config/database.php');

$conn = $database->getConnection();
$chair = new Chair($conn);
$chair->id = $_GET['detailsid'];
$stmt = $chair->readDetails();
while($row = $stmt->fetch(PDO::FETCH_ASSOC)){
?>
添加到购物车:
<div class="addtocart">
<!--<div class="button">

显示处理将项目添加到'$ _SESSION ['cart_arrray']' – Fabricator
的代码请显示$ _SESSION [“cart_array”]的代码 - 它可能会在下面创建一个新项目而不是合并数量,因为数组键是diff – rubberchicken
好的没问题 –
