【问题描述】：
我使用邮件功能制作了联系表格，一切正常。但是，我只是注意到，在发送电子邮件后，每次刷新页面时，即使字段为空，也会不断发送电子邮件。
我的代码如下所示：
<form role="form" method="POST">
<br style="clear:both">
<h3 style="margin-bottom: 25px; text-align: center;">Contact a Conveyancing Property Lawyer Now</h3>
<div class="form-group">
<input type="text" class="form-control" id="name" name="name" placeholder="Name" action="<?php echo htmlspecialchars($_SERVER["PHP_SELF"]);?> required>
</div>
<div class="form-group">
<input type="text" class="form-control" id="email" name="email" placeholder="Email" action="<?php echo htmlspecialchars($_SERVER["PHP_SELF"]);?> required>
</div>
<div class="form-group">
<input type="text" class="form-control" id="mobile" name="mobile" placeholder="Contact Number" action="<?php echo htmlspecialchars($_SERVER["PHP_SELF"]);?> required>
</div>
<div class="form-group">
<input type="text" class="form-control" id="subject" name="subject" placeholder="Subject" action="<?php echo htmlspecialchars($_SERVER["PHP_SELF"]);?> required>
</div>
<div class="form-group">
<select name="situation" id="situation">
<option>Select Current Situation</option>
<option class="placeholder" value="Unemployed">Unemployed</option>
<option class="placeholder" value="Employed">Employed</option>
</select>
</div>
<button type="submit" id="submit" name="submit" class="btn btn-primary">Submit</button>
<?php
if (isset($_POST["submit"])) {
$name = $_POST['name'];
$email = $_POST['email'];
$mobile = $_POST['mobile'];
$subject_line = $_POST['subject'];
$situation = $_POST['situation'];
$from = 'myemail@email.co.za';
$to = 'myemail@email.co.za';
$subject = 'SchoemanLaw lead ...';
$body ="From: $name <br/> E-Mail: $email <br/> Mobile: $mobile Subject: $subject_line <br/> Situation: $situation";
//$body ="From: $name\r\n E-Mail: $email\r\n Mobile:\r\n $mobile Subject: $subject_line\r\n Situation:\r\n $situation";
// set content-type when sending HTML email
$headers = "MIME-Version: 1.0" . "\r\n";
$headers .= "Content-type:text/html;charset=UTF-8" . "\r\n";
// More headers optional/headers
$headers .= "From:$from";
// Check if name has been entered
if (!$_POST['name']) {
$errName = 'Please enter your name';
}
// Check if email has been entered and is valid
if (!$_POST['email'] || !filter_var($_POST['email'], FILTER_VALIDATE_EMAIL)) {
$errEmail = 'Please enter a valid email address';
}
// Check if mobile has been entered
if (!$_POST['mobile']) {
$errMobile = 'Please enter your number';
}
// If there are no errors, send the email
if (!$errName && !$errEmail && !$errMobile) {
if (mail($to,$subject,$body,$headers)) {
$result='<div class="alert alert-success">Thank You ! We will be in touch soon</div>';
echo $result;
} else {
$result='<div class="alert alert-danger">Sorry there was an error sending your message. Please try again later.</div>';
echo $result;
}
}
}
?>
</form>
如何让网站在发送电子邮件后忘记输入字段中的所有详细信息？
我尝试关注这个问题here，但我似乎无法在我的网站上使用它
【问题讨论】：
-
将显示代码与处理代码分开；提交表单时，它会将数据发送到发送电子邮件的处理文件，完成后，它只会将
header()302 重定向到 “thank you” 页面或其他任何内容。由于处理文件只是进行重定向，因此浏览器中不会缓存任何内容，并且该页面无法重新加载。 -
理想情况下我不想重定向到另一个页面
-
您可以将表单和电子邮件处理放在一个文件中，但您需要 发送电子邮件的位与位不同显示“谢谢”消息 - 如果发送电子邮件的位输出 anything 到浏览器，浏览器可以缓存它并可以重新加载。
