Question

我创建了一个简单的提交表单，用户输入他们的电子邮件地址并点击提交，他们的电子邮件地址通过电子邮件发送给我，以便在邮件列表中使用。

出于某种原因，它一直给我同样的错误，实际上不会发送电子邮件：

很抱歉，但这似乎不是有效的电子邮件地址。

这是我的代码：

<?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">
            <h1>test</h1>
            <p>Li Europan lingues es membres del sam familie. Lor separat existentie es un myth. Por scientie, musica, sport etc, litot Europa usa li sam vocabular.

        <?php
            } else {

Answer 1

如果你打开错误报告

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

然后你会得到错误信息：

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

并且那是因为您的表单中没有任何电子邮件。相反，你称之为mailinglist

因此，请将字段名称更改为电子邮件或更改代码以请求mailinglist字段。

Answer 2

很容易看到。你的错误在这里：

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

它应该是这样的：

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

Answer 3

将trim($_POST['email'])更改为trim($_POST['mailinglist'])。

这种简单的联系表格将无法正常运作
