所有字段都必须填充

根据，函数

filter\u var

返回false，或已过滤数据

尝试以下操作：

test.php

if((empty($_POST['name'])) || (empty($_POST['email'])) || (empty($_POST['message']))){
die("All fields must be filled !");
}

$name = $_POST['name'];
$email = $_POST['email'];

$to = 'qadenza@gmail.com';
$subject = 'stojada contact';
$message = 'FROM: '.$name." \nEmail: ".$email."\nMessage: \n".$message;

if (filter_var($email, FILTER_VALIDATE_EMAIL)) { 
mail($to, $subject, $message); 
echo "Thank you! Your email was sent.";
}else{
echo "The email you entered, is not valid.";

你当然已经做了一些基本的调试，比如

print\r（$\u POST）

来确认表单发送了它应该发送的所有内容？好吧，那么问题是…@SobinAugustine，你真的看不到这个问题吗？我们能得到Juhana问题的答案吗？表单是否发送数据？你有没有检查你是否真的收到了$_POST？@sskoko，看起来表单没有发送数据。我将

if（filter\u var…

更改为

if（！filter\u var…

），收到一封空邮件。谢谢，马特，这部分问题似乎解决了。我将更改为

if（！filter…

太棒了！很高兴我能提供帮助。请您深入了解您对代码所做的改进，而不是仅仅发布代码解决方案。

<?php
