Question

好的，我再试一次，这次我删除了多个php打开/关闭标签。所以下面是一大堆php代码。如果我填写表格并发送，重定向工作，我收到电子邮件 - 这一切都很好。最后一个问题是验证 - 我可以提交空字段并重定向到thankyou页面 - 它不会警告用户填写字段......

那么为什么现在验证不起作用？谢谢你的帮助。

Answer 1

header()必须在任何输出之前出现，因此在底部使用它将无效。现在你没有真正的电子邮件'功能'。您可以将该底部代码包装到sendEmail函数中。然后将调用放在if ($_SERVER["REQUEST_METHOD"] == "POST") {末尾的函数中。您必须将所有变量传递给函数。或者你可以通过$ _POST并在一个函数中进行变量清理。

Answer 2

将电子邮件部分移到html之上，之前它自动重定向。在发送电子邮件和重定向之前，您需要添加一个检查以查看是否有帖子请求。在设置$ myemail之后，有一个开放式括号。将其更改为：

if ($_SERVER["REQUEST_METHOD"] == "POST") {

PHP形式的函数顺序
