php - 修改后的 PHP 表单不起作用

我已经从 here 下载了这个“订阅我们的新闻通讯”脚本.

该脚本包含一个表单和一个带有 6 个字段的 mySQL 数据库:id、email、name、date_subscribe、date_unsubscribe 和 status。

表格非常简单:输入您的电子邮件，输入您的姓名并订阅。

我需要对此表单/数据库进行修改，以添加一个我称之为“促销”的额外字段。我已经编辑了 mySQL 数据库，并在 status 之后添加了 promotion 作为 varchar(250)。

我已修改 PHP 脚本以包含此新字段，但当我提交表单时，新 promotion 字段上的内容不会添加到数据库中。

我多次检查了代码和表单，没有发现问题。

这是修改后的表单HTML(我的修改已标记):

我错过了什么？

最佳答案

你的 php 中有这样的东西吗？

if ($subscribe){
$fields = array(
    array('name' => 'email', 'valid' => array('require', 'email')),
    array('name' => 'name', 'valid' => array('require')),
    array('name' => 'promotion', 'valid' => array()),
);
}
