我有一个联系表格，当您单击“完成订单”时，它会检查某些字段是否为空。它应该刷新页面并显示错误消息。
但是我使用页面重命名（一些简单的方法来重命名页面并在同一个php页面上有多个页面）
所以我把联系表格放在 order.php?action=order
这是代码：
<?php
if(isset($_GET['action']) && $_GET['action'] != '') {
$action = $_GET['action'];
} else {
}
?>
<?php
if(isset($action)) {
if($action == 'order') {
?>
<div class="container">
<form method="post" action="<?php echo $_SERVER['PHP_SELF']; ?>" id="contactform">
<fieldset>
<?php if(isset($hasError)) { //If errors are found ?>
<p class="alert-message error">Opps! Looks like you forgot to fill some specify field, please <b>go back</p> and fill the empty field.</p>
<?php } ?>
<?php if(isset($emailSent) && $emailSent == true) { //If email is sent ?>
<div class="alert-message success">
<p style="color: white;" ><strong>Your Order has been Successfully Sent!</strong></p>
<p style="color: white;" >Thank you for submitting your order, <strong><?php echo $pname;?></strong>! Please check your Private Messages folder at <strong><?php echo $forum;?></strong>, as we will get back to you soon. You will redirect back to homepage in less than 5 seconds.<meta HTTP-EQUIV="REFRESH" content="5; url=http://justxp.plutohost.net/jonydesigns/index.php"></p>

<?php
}
elseif($action == 'contact') {
?>
<!-- action=contact info here -->
<?php
}
}
?>
这将启动页面 ?action=order
<?php
if(isset($action)) {
if($action == 'order') {
?>
它显示表单并且一切正常。但是当您填写所有内容并单击完成订单时，它会重定向到 order.php 并且它不显示任何警报，如果订单已发送，它应该显示此警报：
<?php if(isset($emailSent) && $emailSent == true) { //If email is sent ?>
<div class="alert-message success">
<p style="color: white;" ><strong>Your Order has been Successfully Sent!</strong></p>
<p style="color: white;" >Thank you for submitting your order, <strong><?php echo $pname;?></strong>! Please check your Private Messages folder at <strong><?php echo $forum;?></strong>, as we will get back to you soon. You will redirect back to homepage in less than 5 seconds.<meta HTTP-EQUIV="REFRESH" content="5; url=http://justxp.plutohost.net/jonydesigns/index.php"></p>
</div>
<?php } ?>
如果某些内容为空，则应显示此错误：
<?php if(isset($hasError)) { //If errors are found ?>
<p class="alert-message error">Opps! Looks like you forgot to fill some specify field, please <b>go back</p> and fill the empty field.</p>
<?php } ?>
但它根本不显示错误，它所做的只是将您重定向到 order.php 页面，但如果成功，它只会发送电子邮件但不会显示任何警报。
我该如何解决它或导致它发生的原因？

抱歉，代码很大，我只是不知道如何更清楚地问这个问题。
