Question

我正在尝试使用php在我的html文件中包含一个带验证的联系表单。我想答案是在同一页面而不重定向到另一个。我在<!DOCTYPE html>之前添加了php代码段，但在我的页面顶部显示错误消息

同样在联系表单中我得到了标签<?php echo htmlspecialchars($_POST['name']); ?>

等。我是php的新手，所以我需要你的帮助

以下是代码：

    <?php
    if (isset($_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>';
          }

Answer 1

如果您查看“查看来源”，您可能会看到＆lt; ？php-tags，意思是PHP没有被执行。

检查文件的扩展名（必须是X.php，其中x是您想要的名称），并确保您的网络服务器支持PHP。

如果您在本地开发。确保安装了PHP。

查看http://www.php.net下载并安装适用于您操作系统的PHP。如果您使用的是Windows，我建议您安装WAMP。你可以找到它here
