我借用了如何编写PHP电子邮件的代码。但是，而不是他们的：http://www.freecontactform.com/email_form.php我决定使用$PHP_SELF并在一个文件中完成所有操作。
然而，由于错误输出，它正在删除我的联系我们的东西，表格和页脚的东西。
所以我想，一定是个故障，我只是回应联系我们，表格和页脚中的内容，并将错误信息放在表格末尾和页脚之间。
然而，令我烦恼的是，它仍在消除它，并且表现得像我的新东西甚至不存在。为什么这样，我该怎么做才能解决它？我最好像他们一样使用两个单独的文件吗？ （我不喜欢他们的方法，因为一旦他们输入正确或即使他们输错了也没有后退按钮。）
更奇怪的是，如果我确实做到了并且不做错误消息，它确实会输出上面的所有内容，虽然在底部而不是在我原来的形式和形式的位置。
最后，当我查看我的电子邮件时（我知道上面还有其他内容，但在我的主电子邮件中，我使用了我的电子邮件地址，并且也将它放在了来自框中。但是，它没有显示在我的电子邮件中邮箱。

您的died（）函数的输出包含您在下面显示的相同联系表单，稍微重新构建您的代码。
摆脱death（）函数中的表单
function died($error) {
echo "Bla bla bla";
echo "We are very sorry, but there were error(s) found with the form you submitted. ";
echo "These errors appear below.<br /><br />";
echo $error."<br /><br />";
echo "Please go back and fix these errors.<br /><br />";
}
显示验证错误后显示“返回”按钮和表格（如果需要）
