我们如何将 FORM 数据从包含文件传递到另一个页面？

编程问答 2022-04-22

问题描述

我在索引文件中包含了footer.PHP，并且页脚包含用于订阅者注册的FORM。 当我点击提交来自 https://mywebsite.com/index.php 的新订阅者电子邮件时，该值没有从 index.PHP 页面传递，当我使用 url https://mywebsite.com/footer.php

时，同样的代码完全适用

footer.PHP

<form id="newsletterForm" action="newsletter-subscribe.PHP" method="POST">
    <div class="input-group input-group-rounded">
    <input name="mailid" type="email" placeholder="Email Address">
    <span>
    <input type="submit">
    </span>
    </div>
</form>

newsletter-subscribe.PHP

    <?PHP 
         if ($_SERVER["REQUEST_METHOD"] == "POST") {
         $email = $_POST["mailid"];
         $recipient = "info@myemail.com";
         $email_content = "
        
        <html>
        <body>
        <h2>Hello You had a new Subscriber!</h2>
            
        <h3>Email Id : ".$email." </h3>
        </body>
        </html>
        ";
        $email_headers = "MIME-Version: 1.0" . "\r\n";
        $email_headers .= "Content-type:text/html;charset=UTF-8" . "\r\n";

        $email_headers .= 'From: info@myemail.com' . "\r\n";

        if (mail($recipient,$subject,$email_content,$email_headers)) {
            $msg= "Thanks You! For Subscribing our service.";
            echo "<script type='text/JavaScript'>;window.location.href='../index.PHP';</script>";
        } else {
            $error= "Faild To Send Your Order. Please Try Again.";  
            echo "<script type='text/JavaScript'>alert ('$error');window.location.href='index.PHP';</script>";
        }

    } else {        
        $error1= "There was a problem with your submission,please try again.";
        echo "<script type='text/JavaScript'>alert ('$error1');window.location.href='index.PHP';</script>";
    }

?>
