javascript - 发送空白电子邮件的 PHP 脚本无法获取发布数据

Question

index.php 顶部的 PHP 代码。每当我点击提交时，它都会显示已发送的消息，但它会向我的电子邮件地址生成一封空白电子邮件，它不会从帖子中捕获数据。

<?php   
    $emailSubject = 'Customer Has a Question!';
    $webMaster = 'admin@princosoft.com';
    $name = $_POST['iname'];
    $email = $_POST['iemail'];
    $phone=$_POST['iphone'];
    $question = $_POST['imessage'];
    echo $name;
    $body = <<<EOD
    <br><hr><br>
    Name: $name <br>
    Email: $email <br>
    Questions: $question <br>
    EOD;
    $headers = "From: $email\r\n";
    $headers .= "Content-type: text/html\r\n";
    $success = mail($webMaster, $emailSubject, $body, $headers);
    $theResults = <<<EOD
    EOD;
    echo "$theResults";
?>

这就是html+php的全部代码

Answer 1

好吧，看看吧，这里有很多错误。

• 首先，我不是 EOD 的忠实粉丝。所以，我将其更改为只引用。
• 您的文字需要缩进，严重的是，否则您无法阅读。

让我先给你 php，然后是 html。

<?php 
    print_r($_POST);  

    if (isset($_POST['isubmit'])){ // checking if the submit button variable is there from clicking on the button
        // mail variables

        $emailSubject = 'Customer Has a Question!';
        $webMaster = 'admin@princosoft.com';
        $name = $_POST['iname'];
        $email = $_POST['iemail'];
        $phone=$_POST['iphone'];  // please note this variable is not used anymore in the code. You either forgot it in your email, or you dont want anything with this
        $question = $_POST['imessage'];

        echo $name;

        //set up mail body
        $body = "<br><hr><br>";
        $body .= "Name:". $name . "<br>";
        $body .= "Email:". $email ."<br>";
        $body .= "Questions:". $question ."<br>";

        $headers = "From: $email\r\n";
        $headers .= "Content-type: text/html\r\n";
        $headers .= "MIME-Version: 1.0" . "\r\n";

        if (mail($webMaster, $emailSubject, $body, $headers)){
            echo "your mail has been send succesfully";
        }
    } else {
        // this is a test message. Just erase the whole else statement when this all works (for test purposes if the code is read)
        echo "variables aren't set yet"
    }
?>

如您所见，我对您的代码做了一些改动。我确保它检查是否设置了变量。这样，您就可以触发包含所有变量的邮件。现在它会在您每次刷新页面时运行邮件功能。你不会想那样做的。如果它已发送邮件，我也对邮件功能进行了检查，并向其添加了一个额外的 header 。

您应该尝试做的是净化您的输入。现在它不会在数据库中结束，所以这不是什么大问题，但是，如果您确实想将它发送到您自己的数据库以供引用怎么办？添加一个名为 mysqli_real_escape_string() 的函数很简单(如果您的站点上运行着数据库函数，假设您使用 mysqli。如果愿意，请检查一下。

        </div>
    </div>
</form>

我也看了你的html。这里的关键是缩进。有一些可疑的 php 位置，我没有得到。名字的 echo 。如果它们是跳棋，那很好，在最终产品中删除它们，如果它们在那里替换名称，您需要添加它们不同。我在评论中说明了它是如何解决的。 (不确定它是否需要，所以我将解决方案排除在答案之外，您需要的代码已经在这个答案中，您只需将一些部分放在一起)

我还需要补充一点(作为交互设计师)，要求电话号码并不明智，尤其是在涉及转换时(客户留言的频率)。您希望人们与您联系。在网络上留下您的电话号码是“私有(private)”的事情，如果人们要求提供电话号码，它总是会给人带来怀疑。人们不知道他们的电话号码会怎样，所以他们放弃了。说明信息已被谨慎使用。

我的提示:不要将电话字段设为必填字段。只是电子邮件、姓名和消息。
