引导表单验证成功消息未出现

Question

我正在使用引导表单验证问题是表单提交后没有成功消息我在提交时有一个 PHP 邮件函数脚本我在一个新页面中收到 php 消息 echo 'thank you' 即使我写了@ 987654321@ 我在本地 WAMP 服务器上工作。我的问题是如何在同一页面 HTML 成功消息 div 中获得成功消息。谁能指出我正确的方向？

Answer 1

您可能必须使用header("Location: contact_form.php"); 重定向回contact_form
即;

if( mail( $mail_to, $subject, $msg, $headers )) {
        header("Location: contact_form.php?send=success");
} else {
        die("Error!");
}

注意查询字符串参数send=success

现在，在您的contact_form.php 中，在<form class="well form-horizontal" action=" " method="post" id="contact_form"> 之前添加以下条件。

    <?php
    $send_status = $_GET['send'];
    if(isset($send_status)){
    ?>
       <style>
          #success_message {
            display: block;
          }
      </style>
    <?
    }
    ?>

试试这个并告诉我们。
