Question

当我提交表单时，我不断收到如下错误消息。我不确定它是什么。我在WAMP（windows）上运行该站点，并在Dreamweaver CS6中编写它。请注意我对PHP很新。谢谢！

以下是代码：

注意：第29行的S：\ wamp \ www \ latech \ contact.php中的未定义索引：消息

Answer 1

您的姓名属性为msg，您在PHP中将其称为message。

<label for="msg">Your Message</label>
<textarea id="msg" name="msg" spellcheck="true" ></textarea>

$msg    = $_POST['message']; // no need to trim message

也在这里......

$message .= "Name: $name\r\n";
            $message .= "Email: $email\r\n\r\n";
            $message .= "Message:\r\n$msg";

第一次出现应该是$message =，因为没有任何东西可以在没有被初始化时连接。

Answer 2

您正在使用

<textarea id="msg" name="msg" spellcheck="true" ></textarea>

而是使用

<textarea id="msg" name="message" spellcheck="true" ></textarea>

PHP未定义的索引错误与窗体
