Question

我是一名前端开发人员，我是PHP的新手。我使用BootStrap3为我的网站构建联系表单，而表单实际上提交了邮件，我能够在我的Gmail收件箱中收到已发送的邮件，一些PHP标签显示为纯文本。模态形式。如何使错误消息显示为文本，而不是使用PHP标记污染表单？

Boottrap3表格：

<form class="form-horizontal" role="form" method="post" action="index.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" value="<?php echo htmlspecialchars($_POST['name']); ?>">
                <?php echo "<p class='text-danger'>$errName</p>";?><!-- shows all the time as code-->
                </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" value="<?php echo htmlspecialchars($_POST['email']); ?>">
            <?php echo "<p class='text-danger'>$errEmail</p>";?><!-- shows all the time as code-->
        </div>
    </div>
</form>

PHP代码（index.php）

<?php
if ($_POST["submit"]) {
    $name = $_POST['name'];
    $email = $_POST['email'];
    $message = $_POST['message'];
    $human = intval($_POST['human']);
    $from = 'Demo Contact Form';
    $to = 'demo@test.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';
    }

// 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>';
        }
    }
}
?>

Answer 1

在显示包含错误消息的段落之前添加至少if条件，例如：

<?php if ($errName) : ?>
<p class="text-danger"><?php echo $errName ?></p>
<?php endif; ?>

它应该在你的例子中做到。

btw：您的联系表单应作为PHP文件提供。如果它是一个HTML文件，它就不会工作，因为它不会被PHP解释。

Answer 2

试试这个

<?php echo "<p class='text-danger'>".$errName."</p>";?>

PHP标记在HTML代码中显示为纯文本
