【问题描述】：
我一直在尝试使用 php 验证来改进我们的联系表单，我可以让表单得到验证并在每个字段未正确填写时显示错误，当表单完成并正确验证时会显示成功消息，以及包含表单信息的电子邮件已发送给我。
我的问题是我无法让代码的 header('location'...) 部分工作。提交后，表单下方不仅会显示“表单已成功提交”，而是希望它转到“谢谢”页面。
这是我的代码：
这是我的表单页面：
<?php
include('validate.php');
?>
<!DOCTYPE html>
<html lang="en">
<head>
<title>TEST</title>
<style>
input, textarea {font-size: 1em;}
p.error {background: #ffd; color: red;}
p.error:before {content: "Error:";}
p.success {background: #ffd; color: green;}
p.success:before {content: "Success:";}
p.error, p.success {font-weight: bold;}
</style>
</head>
<body>
<h2>Please fill up the form below and submit.</h2>
<?=$error?>
<form action="html_form_to_validate.php" method="post">
<table>
<tr>
<td>Name: </td>
<td>
<input type="text" name="name" placeholder="Name *(Required)" value="<?=@$name?>"/> </td>

<tr>

<td><textarea name="comments"><?=@$comments?></textarea></td>
</tr>
</table>
<input type="submit" name="submit" value="Submit"/> <input type="reset" name="reset" value="Reset"/>
</form>
<?php
if (isset($_POST['submit']) && $error == '') { // if there is no error, then process further
echo "<p class='success'>Form has been submitted successfully.</p>"; // showing success message
$name=$_POST['name'];
$company=$_POST['company'];

";
$headers = "MIME-Version: 1.0\r\n";
$headers .= "Content-type: text/html; charset=iso-8859-1\r\n";
$headers .= "From: $from\r\n";
@mail($to, $subject, $message, $headers);
header('Location: http://www.example.com/contact/thank-you.php');
}
?>
</body>
</html>
还有我的 validate.php 文件：
<?php
$error = ""; // Initialize error as blank
if (isset($_POST['submit'])) { // check if the form is submitted
#### removing extra white spaces & escaping harmful characters ####
$name = trim($_POST['name']);
$company = trim($_POST['company']);
$hear = trim($_POST['hear']);
$email = $_POST['email'];
$phone = $_POST['phone'];
$comments = $_POST['comments'];
#### start validating input data ####
#####################################
# Validate Name #
// if name is not 3-20 characters long, throw error
if (strlen($name) < 3 OR strlen($name) > 20) {
$error .= '<p class="error">Name should be within 3-20 characters long.</p>';
}
# Validate Email #
// if email is invalid, throw error
if (!filter_var($email, FILTER_VALIDATE_EMAIL)) { // you can also use regex to do same
$error .= '<p class="error">Enter a valid email address.</p>';
}
# Validate Phone #
// if phone is invalid, throw error
if (!ctype_digit($phone) OR strlen($phone) < 9) {
$error .= '<p class="error">Enter a valid telephone number.</p>';
}
# Validate Comments #
if (strlen($comments)==0 OR strlen($comments)>240) {
$error .= '<p class="error">Please enter your message less than 240 characters.</p>';
}
#### end validating input data ####
#####################################
}
我是一个新手，并且已经使用其他地方的脚本来做我想做的事情 - 所以请友好，哈哈
谢谢
