Question

问题是联系表单会将我重定向到另一个带有成功消息的页面，而不是显示在代码所指示的同一页面上。

以下是HTML部分：

    <form class="form-horizontal" role="form" method="post" action="contact.php">
    <div class="form-group">
        <label for="name" class="col-sm-2 control-label">Name</label>
        <div class="col-sm-10">
            <input type="text" class="form-control" id="name" name="name" placeholder="First & Last Name" value="">
        </div>
    </div>
    <div class="form-group">
        <label for="email" class="col-sm-2 control-label">Email</label>
        <div class="col-sm-10">
            <input type="email" class="form-control" id="email" name="email" placeholder="example@domain.com" value="">
        </div>
    </div>
    <div class="form-group">
        <label for="message" class="col-sm-2 control-label">Message</label>
        <div class="col-sm-10">
            <textarea class="form-control" rows="4" name="message"></textarea>
        </div>
    </div>
    <div class="form-group">
        <label for="human" class="col-sm-2 control-label">2 + 3 = ?</label>
        <div class="col-sm-10">
            <input type="text" class="form-control" id="human" name="human" placeholder="Your Answer">
        </div>
    </div>
    <div class="form-group">
        <div class="col-sm-10 col-sm-offset-2">
            <input id="submit" name="submit" type="submit" value="Send" class="btn btn-primary">
        </div>
    </div>
    <div class="form-group">
        <div class="col-sm-10 col-sm-offset-2">
            <! Will be used to display an alert to the user>
        </div>
    </div>
</form>

这是php：

    <?php
    if ($_POST["submit"]) {
        $name = $_POST['name'];
        $email = $_POST['email'];
        $message = $_POST['message'];
        $human = intval($_POST['human']);
        $from = 'Demo Contact Form'; 
        $to = 'example@domain.com'; 
        $subject = 'Message from Contact Demo ';

        $body ="From: $name\n E-Mail: $email\n Message:\n $message";

        // 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 message has been entered
        if (!$_POST['message']) {
            $errMessage = 'Please enter your message';
        }
        //Check if simple anti-bot test is correct
        if ($human !== 5) {
            $errHuman = 'Your anti-spam is incorrect';
        }

// If there are no errors, send the email
if (!$errName && !$errEmail && !$errMessage && !$errHuman) {
    if (mail ($to, $subject, $body, $from)) {
        $result='<div class="alert alert-success">Thank You! I will be in touch</div>';
    } else {
        $result='<div class="alert alert-danger">Sorry there was an error sending your message. Please try again later.</div>';
    }
}
    }
?>

我已经尝试过其他用户在此处发布的修补程序，但没有一个能够正常运行。

谢谢！

检查变量是否使用isset（）

定义

  if (!isset($errName) && !isset($errEmail) && !isset($errMessage) && !isset($errHuman)) {
        // do stuff
    }

Bootstrap联系表格 - 不会在同一页面上显示成功消息
