我的PHP联系人从给我发送电子邮件，但其中一部分留空

Question

我正在使用主题，这是它附带的php。 我正在测试电子邮件，我注意到的一件事是，无论我做什么，都有几个部分不断弹出空白。 这是我第一次使用php，我不确定是否应该删除主题php并创建自己的主题。 具体来说，数字，地址，城市，州，日期，邮政编码是空白的文本。 我收到了电子邮件，但这些部分一直空白。 我的代码不正确吗？

Answer 1

看来变量没有从$ _POST获得任何值

因此，在以下行// Sanitize input添加以下行

$number = filter_var($_POST["number"], FILTER_SANITIZE_STRING);
$adress = filter_var($_POST["Adress"], FILTER_SANITIZE_STRING);
$City = filter_var($_POST["City"], FILTER_SANITIZE_STRING);
$State = filter_var($_POST["State"], FILTER_SANITIZE_STRING);
$Date = filter_var($_POST["date"], FILTER_SANITIZE_STRING);
$Zcode = filter_var($_POST["ZCode"], FILTER_SANITIZE_STRING);

您是否尝试过联系主题支持人员？ 他们可能会获得您（我们）需要的信息，包括应该如何工作，所需的环境（即PHP5.6与PHP7.1，启用/禁用了哪些模块），并且很高兴知道您也在使用什么环境。
