创建了一个表单，它使用php检查错误，但在成功提交后，它不会重定向到我创建的响应页面（thanks.php）。它重定向到具有相同标题和页面格式的同一联系页面，但没有实际文本和bodytext div不显示。我只需要它重定向到我创建的响应页面。有什么帮助吗？
以下是代码：
<?php
$firstnameerror=$browsererror=$sexerror=$dateerror=$visiterror=$judgementerror=$emailerror=$emailconfirmerror="";
if (isset($_GET['submit'])){
$browser = htmlspecialchars($_GET['browser']);
$firstname = htmlspecialchars($_GET['firstname']);
$lastname = htmlspecialchars($_GET['lastname']);
$sex = htmlspecialchars($_GET['sex']);
$date = htmlspecialchars($_GET['date']);
$visit = htmlspecialchars($_GET['visit']);
$judgement = htmlspecialchars($_GET['judgement']);
$message = htmlspecialchars($_GET['message']);
$email = htmlspecialchars($_GET['email']);
$emailconfirm = htmlspecialchars($_GET['emailconfirm']);
echo "<p>form submitted</p>";
if (isset($browser) && isset($firstname) && isset($lastname) && isset($sex) && isset($date) && isset($visit)
&& isset($judgement) && isset($message) && isset($email) && isset($emailconfirm)){
echo "<p>all fields were submitted</p>";}
if (empty($firstname)){
$firstnameerror .= "<div class= 'error'>First name is missing</div>";}
if (empty($browser)){
$browsererror .= "<div class= 'error'>Tell us where you're from</div>";}
if (empty($sex)){
$sexerror .= "<div class= 'error'>Gender is missing</div>";}
if (empty($date)){
$dateerror .= "<div class= 'error'>Date is missing</div>";}
if (empty($visit)){
$visiterror .= "<div class= 'error'>Tell us what you visited</div>";}
if (empty($judgement)){
$judgementerror .= "<div class= 'error'>Tell us what you thought</div>";}
if (!empty($email) && empty($emailconfirm)){
$emailerror .= "<div class= 'error'>Please confirm your email</div>";}
if ($email != $emailconfirm){
$emailconfirmerror .= "<div class='error'>Make sure your emails match.</div>";}
if (empty($browsererror) && empty($firstnameerror) && empty($sexerror) && empty($dateerror) && empty($visiterror) && empty($judgementerror) && empty($emailerror)
&& empty($emailconfirmerror)){
header('Location: thanks.php');
exit();
}
}

在回显内容后，您无法重定向。删除此回显，它将重定向：
echo "<p>form submitted</p>";

empty仅在变量不存在或设置为false时触发。如果创建没有值的变量，empty将不会触发。
因此，请更改条件语句：
empty($browsererror)
致：
!$browsererror

你不能在任何输出之后使用header("location: somewhere.php");，无论是空格还是H或Hi，都无法使用它。
您必须在显示任何数据之前处理表单数据。此外，您应该使用JS验证，因为这样您就不必向服务器发出innecesarias请求并帮助服务器接收足够的数据并记住，不输出在致电header("location: somewhere.php");
