我正在尝试让我的网站上的联系表正常运行。我分别得到关于$name
, $email
, $thesubject
,$message
变量的未定义索引。
谁能告诉我我需要做什么才能正确发送电子邮件?
HTML/表格:
<div class="alert success success-message">
<div class="close">×</div>
<p>Your message has been sent!</p>
</div>
<form class="clearfix" method="post" action="contact.php">
<div class="field">
<label>Name <span>*</span></label>
<input type="text" name="name" class="text" value="" />
</div>
<div class="field">
<label>Email <span>*</span></label>
<input type="email" name="email" class="text" value="" />
</div>
<div class="field field-last">
<label>Subject <span>*</span></label>
<input type="text" name="thesubject" class="text" value="" />
</div>
<textarea name="message" class="text"></textarea>
<button id="send" class="btn">Submit</button>
<div class="loading"></div>
</form>
</div>
PHP:
<?php
//Retrieve form data.
//GET - user submitted data using AJAX
//POST - in case user does not support javascript, we'll use POST instead
$name = ($_GET['name']) ? $_GET['name'] : $_POST['name'];

$thesubject = ($_GET['thesubject']) ?$_GET['thesubject'] : $_POST['thesubject'];
$message = ($_GET['message']) ?$_GET['message'] : $_POST['message'];
//flag to indicate which method it uses. If POST set it to 1
if ($_POST) $post=1;
//Simple server side validation for POST data, of course, you should validate the email
if (!$name) $errors[count($errors)] = 'Please enter your name.';
if (!$email) $errors[count($errors)] = 'Please enter your email.';
if (!$thesubject) $errors[count($errors)] = 'Please enter your subject.';
if (!$message) $errors[count($errors)] = 'Please enter your message.';
//if the errors array is empty, send the mail
if (!$errors) {
