我创建了一个简单的html / php表单,我的网站上的访问者可以写下他们的姓名,电子邮件和消息,然后将消息发送到我的电子邮箱。问题是,当他们提交电子邮件时,我的网站会执行完全刷新(看起来像),因此只需重新加载到我的网站顶部。我希望用户在提交后保持相同的滚动位置,以便他们可以立即查看提交是否成功。因此,要么是阻止刷新的解决方案,要么是自动向下滚动到表单的其他解决方案。
你能告诉我这是否可以使用php?或者我是否必须使用一些jquery / ajax解决方案?
以下是我正在使用的代码。我是一个完整的新手,所以请保持温和。
<form action="" method="post" id="form">
<div class="contact-info-group">
<label for="name"><span>Your name</span>
<input type="text" id="name" name="name" autocomplete="off" value="<?php echo $name; ?>"></label>
<label for="email"><span>Your email</span>
<input type="email" id="email" name="email" autocomplete="off"></label>
</div>
<label for="message"><span>Your message</span>
<textarea id="message" name="message"></textarea></label>
<input id="button1" type="submit" class="button next" name="contact_submit" value="Send message">
<?php
// Check for header injections
function has_header_injection($str) {
return preg_match("/[\r\n]/", $str);
}
if (isset ($_POST['contact_submit'])) {
$name = trim($_POST['name']);
$email = trim($_POST['email']);
$msg = $_POST['message'];
// Check to see if $name or $email have header injections
if (has_header_injection($name) || has_header_injection($email)) {
die();
}
if (!$name || !$email || !$msg) {
echo '<div class="contact-warning"><h2>! Error - Please note that all of the above fields are required !</h2></div>';
exit;
}
// Add the recipient email to a variable
$to = "email@email.com";
// Create a subject
$subject = "Message via website.com - $name";
// Construct the message
$message = "Name: $name\r\n";
$message .= "Email: $email\r\n";
$message .= "Message: \r\n\r\n$msg";
// Clean up the message
$message = wordwrap($message, 72);
// Set the mail headers into a variable
$headers = "MIME-Version 1.0\r\n";
$headers .= "Content-type: text/plain; charset=iso-8859-1\r\n";
$headers .= "From: $name <$email> \r\n";
$headers .= "X-Priority: 1\r\n";
$headers .= "X-MSMail-Priority: High\r\n\r\n";
// Send the email
mail($to, $subject, $message, $headers);
echo '<div class="contact-warning"><h2>Thank you for your message. We will get back to you shortly.</h2></div>';
}
?>
