我是 PHP 的初学者。我被困在看起来很容易的事情上。我建立了一个网站，网站上有一个页面，人们可以通过表格向我发送电子邮件。问题是，我认为表单似乎无法创建 $POST_['name']。只需阅读代码，您就会明白我在说什么。
<form action="?" method="post">
<div id="right">
<label for="name"> <input type="text" class="kutu" name="name" ></label><br />
<label for="email"> <input type="email" class="kutu" name="email" ></label><br />
<label for="subject"> <input type="text" class="kutu" name="subject" ></label><br />
</div>
<div id="left">
<p>Name: </p>
<p>Your Email Adress: </p>
<p>Subject: </p>
</div>
<div id="bottom">
<p>Your Message:</p><br />
<label for="message"><textarea name="message" rows="3" cols="60"> </textarea></label>
</div>
<input type="submit" id="tus" value="submit">
</form>
这是PHP
if (isset($POST_['name'])) {
$email = $POST_['email'];
$subject = $POST_['subject'];
$message = "From: " . $POST_['name'] . ", " . $POST_['email'] . "\n Message: " . $POST_['message'];
try {
mail("myEmailAdress@gmail.com", $subject, $message, " ");
unset($POST_['name']);
header("Location: success.php");
}
catch (PDOException $e)
{
include 'index.html';
exit();
}
exit();
}
include 'contact2.php';
当我提交表单时，它再次将我带到 contact2.php，它告诉我 POST_['name'] 从来没有被创建过。
