从PHP和HTML联系表单获取空电子邮件

Question

我是网页设计和开发的学生，试图制作一个网站。我已经使用php和html为网站创建了联系表单。我是 php 的新手，所以我对它一无所知。我从网站上复制了一个代码，通过它我收到一封电子邮件，但空的[没有我在网站联系表格上输入的信息]。这是我的HTML代码[文件名：联系人.html]：-

 <div class="login-w3l">    
            <div class="top-img-agileits-w3layouts">
                <h2 class="sub-head-w3-agileits">Contact Us</h2>
                <p>Fillout the form below !</p>
                <div class="login-form">    
                <form action="handler.php" method="post" enctype="multipart/form-data">
                    <input type="text" name="Name" placeholder="First Name" required="" />
                    <input type="text" name="Name" placeholder="Last Name" required="" />
                    <input type="email" name="Email" placeholder="Email" required="" />
                    <input type="text" name="Subject" placeholder="Subject" required="" />
                    <textarea name="Message" placeholder="Message" required=""></textarea>
                    <input type="submit" value="Send">
                </form> 
            </div>
            </div>          

                </div> 
-----End of HTML-----

这是我的PHP代码[文件名：处理程序.php]：-

<?php
$first_name = $_POST ['first name'];
$last_name = $_POST ['last name'];
$visitor_email = $_POST ['email'];
$message = $_POST ['message'];
$email_from = '[e-mail]';
$email_subject = "WMS Contact form";
$email_body = "User First Name :  $first_name n".
                                        "User Last Name :  $last_name n".
                                                "User Email :  $visitor_email n ".
                                                        "User Message : $message n";
 $to = "[e-mail]";   
 $headers = "From: $email_from rn";
 $headers .= "Reply To: $visitor_email rn";

 mail($to, $email_subject, $email_body, $headers);
 header("Location: contact.html");
?>

首先，您需要适当地设置表单元素的格式。 添加唯一的name和id属性与表单提交相关。 因此，我更新了您的名称和id元素以匹配您的php脚本正在寻找的内容。

<div class="login-w3l">
    <div class="top-img-agileits-w3layouts">
        <h2 class="sub-head-w3-agileits">Contact Us</h2>
        <p>Fillout the form below !</p>
        <div class="login-form">
            <form action="handler.php" method="post" enctype="multipart/form-data">
                <input type="text" name="first_name" id="first_name" placeholder="First Name" required=""/>
                <input type="text" name="last_name" id="last_name" placeholder="Last Name" required=""/>
                <input type="email" name="email" id="email" placeholder="Email" required=""/>
                <input type="text" name="subject" id="subject" placeholder="Subject" required=""/>
                <textarea name="message" id="message" placeholder="Message" required=""></textarea>
                <input type="submit" value="Send">
            </form>
        </div>
    </div>
</div> 

之后，顶部的变量现在应该用您之前填写的表单元素填充。

这是您编辑的PHP实际工作：

<?php
$first_name = $_POST['first_name'];
$last_name = $_POST['last_name'];
$visitor_email = $_POST['email'];
$message = $_POST['message'];
$subject = $_POST['subject'];
....
?>

Answer 2

确保 name 和 id 属性全部小写且没有空格。

也不要在$_POST和[]之间添加空格。

尝试使用：

<div class="login-w3l">
    <div class="top-img-agileits-w3layouts">
        <h2 class="sub-head-w3-agileits">Contact Us</h2>
        <p>Fillout the form below !</p>
        <div class="login-form">
            <form action="handler.php" method="post" enctype="multipart/form-data">
                <input type="text" name="first_name" id="first_name" placeholder="First Name" required=""/>
                <input type="text" name="last_name" id="last_name" placeholder="Last Name" required=""/>
                <input type="email" name="email" id="email" placeholder="Email" required=""/>
                <input type="text" name="subject" id="subject" placeholder="Subject" required=""/>
                <textarea name="message" id="message" placeholder="Message" required=""></textarea>
                <input type="submit" value="Send">
            </form>
        </div>
    </div>
</div>

.PHP：

<?php
$first_name = $_POST['first name'];
$last_name = $_POST['last name'];
$visitor_email = $_POST['email'];
$message = $_POST['message'];
$email_from = '[e-mail]';
$email_subject = "WMS Contact form";
$email_body = "User First Name :  $first_name n".
              "User Last Name :  $last_name n".
              "User Email :  $visitor_email n ".
              "User Message : $message n";
 $to = "[e-mail]";   
 $headers = "From: $email_from rn";
 $headers .= "Reply To: $visitor_email rn";

 mail($to, $email_subject, $email_body, $headers);
 header("Location: contact.html");
?>
