如何在PHP联系表单中放置段落？

Question

我在PHP中编写了一个联系表单，我希望在发送的消息中包含段落，这样用户就必须写入某些段落而不只是一个文本块。

我试图将message分成多个textareas，但我不知道如何调整PHP代码，以便这些textareas将以正确的顺序发送到一个message内。每个textareash可以提出一个段落。

这是我的PHP：

<?php 
    $name = $_POST['name'];
    $email = $_POST['email'];
    $message = $_POST['message'];
    $from = 'From: mywebsite.com'; 
    $to = '[email protected]'; 
    $subject = 'subject line';
    $body = "From: $name\n E-Mail: $email\n Message:\n $message";

    $headers .= "MIME-Version: 1.0\r\n";
    $headers .= "Content-type: text/html\r\n";
    $headers .= 'From: '. $email. "\r\n" .
    $headers .= "Reply-To: ". $email. "\r\n";
    $headers .= "X-Mailer: PHP/" . phpversion();

    $status = mail($to, $subject, $message, $headers);

    if ($status) { 
        echo '<p style="color: white">Your Message was sent!</p>';
    } else { 
        echo '<p style="color: white">Something went wrong. Please try again.</p>'; 
    }
?>

这是我的HTML：

<div class="contact-form">
    <form id="contact-form" method="post" action="contact-form-handler.php">
        <input name="name" type="text" class="form-control" placeholder="Your Name" required>
        <br>
        <input name="email" type="email" class="form-control" placeholder="Your Email">
        <br>
        <textarea name="message" class="form-control" placeholder="Message" rows="30" required></textarea><br>
        <input type="submit" class="form-control" value="SEND MESSAGE">
    </form>
</div>

Answer 1

https://www.php.net/manual/en/function.nl2br.php

当您使用nl2br时，您可以将“\ n”从textarea更改为“ “。您可以发送内容类型：文本/普通邮件，而不必将换行符转换为 标签。

我没有在你的代码中看到多个textareas所以我猜nl2br是你正在寻找的功能。

Answer 2

我补充说：

$message = nl2br($message); // Inserts HTML line breaks <br />

这应该插入HTML换行符。

$name = $_POST['name'];
$email = $_POST['email'];
$message = $_POST['message'];
$from = 'From: mywebsite.com';
$to = '[email protected]';
$subject = 'subject line';
$body = "From: $name\n E-Mail: $email\n Message:\n $message";

$headers .= "MIME-Version: 1.0\r\n";
$headers .= "Content-type: text/html\r\n";
$headers .= 'From: ' . $email . "\r\n" .
$headers .= 'Reply-To: ' . $email . "\r\n";
$headers .= 'X-Mailer: PHP/' . phpversion();

$message = nl2br($message); // <-- added to Inserts HTML line breaks.

$status = mail($to, $subject, nl2br($message), $headers);

if ($status) {
    echo '<p style="color: white">Your Message was sent!</p>';
} else {
    echo '<p style="color: white">Something went wrong. Please try again.</p>';
}
