我已经尝试了很多东西，但我不能得到一个干净的HTML或PHP代码来防止用户提交一个表单与空字段(我不知道它是否可以做到)。我不认为我可以做一个javascript，因为HTML文件的主机自动剥离头部…到目前为止，PHP操作将带有表单结果的电子邮件发送到一个普通的@地址。下面是表单，然后是PHP动作(抱歉，我是PHP编码新手):

问题在哪里?你可以这样做:
$error = false;
foreach(...)
{
// set $error = true if empty (I'd also check for invalid values if I were you)
}
if($error)
{
echo 'error message';
// display form again using value="$_POST['fieldname']"
}
else
{
//...
mail(...);
echo 'thank you message';
}
我看到您正在创建一个$error标志，但看起来好像您正在对它做任何事情。您应该测试这个$error并显示一个不同的HTML结果(并且放弃通过电子邮件发送结果)，如果它存在的话。
