我创建了一个dvd的数据库，脚本读取和运行良好

我很难知道下一步该怎么办

当用户按下dvd标题的复选框和“添加到购物车”按钮时，我希望脚本将用户重定向到handlebasket.php并添加选中的dvd

任何帮助都将不胜感激

2010年及以后
2000 - 2009
1990 - 1999    
我建议使用复选框的名称，这将创建一个数组：
print "<input type=\"checkbox\" name=\"addToCart[]\" value=\"" . $row['ID'] . "\"/>"

打印“”

通过这种方式，您可以像$\u POST[“addToCart”]
那样以数组的方式访问handlebasket.php
中标记的DVD的ID，以便您可以对其进行迭代
请注意，如果用户未选中任何复选框，则可能不会设置该参数，即$\u POST
没有键“addToCart”
