這種簡單的聯系方式無法正常運行

Question

我創建了一個簡單的提交表單，用戶在其中輸入他們的電子郵件地址並單擊提交，然后將他們的電子郵件地址通過電子郵件發送給我，以便在郵件列表中使用。

由於某種原因，它總是給我同樣的錯誤，並且實際上不會發送電子郵件：

抱歉，這似乎不是有效的電子郵件地址。

這是我的代碼：

<?php define('access', true); ?>
<?php
    // Configuration
    $emailTo = 'myemail@mydomain.com'; // The e-mail address
    $mySite = 'test Mailing List'; // The name of the website
    $subject = 'test | New Mailing Lister!';
    $msg = '';

    // If the form is submitted
    if(isset($_POST['submit'])) {
        // Check that the email entered is valid and not empty
        if(trim($_POST['email']) == '') {
            $hasError = true;
            $msg = '<p class="error">Sorry but that doesn\'t seem to be a valid e-mail address.</p>';
        } else if (!eregi("^[A-Z0-9._%-]+@[A-Z0-9._%-]+\.[A-Z]{2,4}$", trim($_POST['email']))) {
            $hasError = true;
            $msg = '<p class="error">Sorry but that doesn\'t seem to be a valid e-mail address.</p>';
        } else {
            $email = trim($_POST['email']);
        }

        // Are we error free? If so send away
        if(!isset($hasError)) {
            $body = "Someone has signed up for the test mailing list, the e-mail address they used is:\n\n<strong>$email</strong>";
            $headers = 'From: ' . $mySite . ' <' . $emailTo . '>' . "\r\n" . 'Reply-To: ' . $email;
            $msg = '<p class="thanks">Thanks for subscribing to test\'s services mailing list. We\'ll keep you posted on service updates!</p>';

            mail($emailTo, $subject, $body, $headers);
            $emailSent = true;
        }
    }
?>
<?php include('includes/html_header.php'); ?>
    <?php include('includes/header.php'); ?>

    <div id="container">
        <?php if(!isset($_GET['id'])) { ?>
        <div id="container_column-1">

Answer 1

如果您要打開錯誤補給

<?php
error_reporting(E_ALL);
ini_set('display_errors','on');

那么您將收到錯誤消息：

Notice: Undefined index: email in %script% on line %line%

那就是因為您沒有在表單中提交任何電子郵件。 相反，您稱它為mailinglist

因此，請將字段名稱更改為email或將您的代碼更改為要求一個mailinglist字段。

Answer 2

很容易看到。 您的錯誤在這里：

<input type="text" size="35" name="mailinglist" id="mailinglist" title="Enter your e-mail address" />

應該是這樣的：

<input type="text" size="35" name="email" id="mailinglist" title="Enter your e-mail address" />

Answer 3

將trim($_POST['email'])更改為trim($_POST['mailinglist']) 。
