我试图让我的php邮件程序正常工作，同时当有人不填写信息时显示错误。我有一定程度的工作，但现在不会显示错误。
//侧面问题//
我遇到的问题是用户按下“发送”，而不是将表单停留在同一位置，而是页面跳回到顶部。有谁知道我如何允许它保留在表格上
PHP
include("includes/config.php");
if(isset($_POST['submit']))
{
//echo "submit was pressed";
if(strlen($_POST['firstname']) > 1)
{
$firstname = $_POST['firstname'];
//echo $firstname;
}
else
{
$errors['firstname'] = "<span class=\"error\">Please enter a firstname</span>";
}
if(strlen($_POST['email']) > 1)
{
$email = $_POST['email'];
//echo $email;
if(filter_var($email, FILTER_VALIDATE_EMAIL))
{
$email = $email;
}
else
{
$errors['email'] = "<span class=\"error\">Please enter a VALID email address</span>";
}
}
else
{
$errors['email'] = "<span class=\"error\">Please enter an email address</span>";
}
if(strlen($_POST['comments']) > 1)
{
$comments = $_POST['comments'];
//echo $comments;
}
else
{
$errors['comments'] = "<span class=\"error\">Please enter a comment</span>";
}
if($errors < 1)
{
include("includes/class.phpmailer.php");
$mail = new PHPMailer;
$to = "erin@gmail.com";
$from = $email;
$from_name = $firstname;
$subject = "You've got mail from " . $firstname;
$body = "Their comments <br/><br/>" . $comments;
$mail->From = $from;
$mail->FromName = $from_name;
$mail->addAddress($to, 'Erin');
$mail->addReplyTo($from, $from_name);
$mail->isHTML(true);
$mail->Subject = $subject;
$mail->Body = $body;
if(!$mail->send()) {
echo 'Message could not be sent.';
echo 'Mailer Error: ' . $mail->ErrorInfo;
} else {
//echo 'Message has been sent';
$success = "<p class=\"success\">Your message has been sent successfully.</p>";
unset($firstname);
unset($email);
unset($comments);
}
}
}
?>
HTML表单
<div id="form-div">
<?= $success; ?>
<form action="<?php echo $_SERVER["PHP_SELF"]; ?>" method="post">
<p class="name">
<?= $errors['firstname']; ?><br>
<input name="firstname" type="text" class="validate[required,custom[onlyLetter],length[0,100]] feedback-input" placeholder="Name" id="name" value="<?= $firstname; ?>" />
</p>
<p class="email">
<?= $errors['email']; ?><br>
<input name="email" type="text" class="validate[required,custom[email]] feedback-input" id="email" placeholder="Email" value="<?= $email; ?>"/>
</p>
<p class="text">
<?= $errors['comments']; ?><br>
<textarea name="text" class="validate[required,length[6,300]] feedback-input" id="comment" placeholder="Comment"><?= $comments; ?></textarea>
</p>
<div class="submit">
<input type="submit" value="SEND" id="button-blue"/>
<div class="ease"></div>
</div>
</form>
</div>

最佳答案
您的页面将产生很多错误，因为在加载页面时，您引用的是 undefined variable -例如，在首次加载页面时未定义$errors['firstname']，但是您仍然要求其显示。这些错误应该正常显示-如果不是，您可能已经关闭了错误报告功能，这在开发时不是一个好主意，因此您应该检查Web服务器日志以查看其他错误。
因为它正在重新加载页面，所以它“跳回顶部”。如果您通过ajax请求提交表单，则不会发生。
