Question

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方框时，按“添加到购物车”，我希望该项目显示在'handlebasket.php'上

我该怎么做？

Answer 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[]" />

并在handlebasket.php中，编写下面的代码来获取这些值并显示

foreach（$ _ POST ['复选框']为$复选框）{

echo $复选框。 '';

}
