Question

我的WordPress网站上有一个简单的表单，允许用户注册简报：

HTML

<form method="POST" action="newsletter.php">
<input type="text" class="form" name="Email" size="20" placeholder="Email address">
<input type="submit" class="button" value="Submit" name="Submit"></p>
</form>

提交电子邮件地址后，用户将被重定向到名为newsletter.php的新网站，并显示以下消息：您的电子邮件地址已成功提交

PHP

<?php
$recipient = "blabla@mail.com";
$subject = "Newsletter subscription";
$sender = $recipient;
$body .= "Add this email adress to the newsletter: \n";
$body .= " ".$_REQUEST['Email']." \n";
mail( $recipient, $subject, $body, "From: $sender" ) or die ("Mail could not be sent.");
echo "Your email address has been successfully submitted";
?>

我现在想知道的是：如何在WordPress网站上显示“成功消息”而不是newsletter.php？

完美的解决方案是在注册表单下方打开一个小div。

Answer 1

您可以将表单更改为：

<form method="POST">
    <input type="text" class="form" name="Email" size="20" placeholder="Email address">
    <input type="submit" class="button" value="Submit" name="Submit"></p>
</form>

（No action属性表示“提交到当前网址”。）

然后将PHP添加到表单所在的同一页面，并添加一个检查，以便它只在表单提交后运行：

<?php
    if(isset($_POST['Email'])) {
        $recipient = "blabla@mail.com";
        $subject = "Newsletter subscription";
        $sender = $recipient;
        $body .= "Add this email adress to the newsletter: \n";
        $body .= " ".$_REQUEST['Email']." \n";
        mail( $recipient, $subject, $body, "From: $sender" ) or die ("Mail could not be sent.");
        echo "<div>Your email address has been successfully submitted</div>";
    }
?>

您可能还希望将错误处理策略更改为输出<div class="error">或某些而不是死亡。

我有一段时间没有使用Wordpress，所以我不确定那里的具体细节，但如果这是一个准系统的PHP网站，你可以在第一页的源代码中将它们全部放在一起：

<form method="POST">
    <input type="text" class="form" name="Email" size="20" placeholder="Email address">
    <input type="submit" class="button" value="Submit" name="Submit"></p>
</form>

<?php
    if(isset($_POST['Email'])) {
        $recipient = "blabla@mail.com";
        $subject = "Newsletter subscription";
        $sender = $recipient;
        $body .= "Add this email adress to the newsletter: \n";
        $body .= " ".$_REQUEST['Email']." \n";
        mail( $recipient, $subject, $body, "From: $sender" ) or die ("Mail could not be sent.");
        echo "<div>Your email address has been successfully submitted</div>";
    }
?>

Answer 2

您可以将页面发布到自身并在那里处理订阅，而不是发布到Newsletter.php。或者Newsletter.php可能是无头的，并将您重定向回引用者，然后您可以在其中显示订阅消息。但这是相当陈旧的，任何Ajax后期解决方案肯定会更加性感。

Answer 3

If $sender = $recipient;

然后如何知道谁访问了该网站并订阅了该页面。相反，发件人邮件必须是订阅新闻通讯的人的电子邮件地址。
