技术标签:
【中文标题】购物车，加入购物车按钮功能【英文标题】：shopping cart, add to cart button function 【发布时间】：2014-04-03 14:38:43 【问题描述】：脚本从数据库中读取产品并将项目放入表中。还包括每个项目旁边的复选框并添加到购物车按钮。
当用户选中一个或多个框并按下“添加到购物车”时，我希望该项目显示在“handlebasket.php”上
我该怎么做？

【问题讨论】：
【参考方案1】：将复选框值发送到 handlebasket.php
<input type="checkbox" class='form' value="1" name="checkbox[]" />
<input type="checkbox" class='form' value="2" name="checkbox[]" />
在handlebasket.php 中，编写下面的代码来获取这些值并显示
foreach($_POST['checkbox'] as $checkbox)
回显 $checkbox 。 '';
【讨论】：
喜欢这个打印 "while ($row = mysql_fetch_array($retval, MYSQL_ASSOC))//what u need is create couple of these for each decade etc then sorround in if state ?><tr><td><input type=\"checkbox\" name=<?=$row['ID']?> /></td><td><?=$row['DVD_Title']?></td> <td><?=$row['Price']?></td><td><?=$row['Year']?></td></tr><br/> <?
