我需要一个非常简单但有效的 PHP 表单处理程序来处理这个表单:
<form id="contact" method="post" action="contact_handle.php">
<label for="name">Name:</label>
<input type="text" class="text_style" placeholder="John Doe" name="name" /><br />
<label for="email">Email:</label>
<input type="email" class="text_style" placeholder="email@example.com" name="email" /><br />
<label for="message">Subject:</label>
<textarea class="areawidth" rows="4" name="message" /></textarea><br />
<button id="contactbutton" type="submit">Submit</button>
</form>
这是我目前拥有的,但它不会发送电子邮件,也不会像我预期的那样重定向。而且我似乎无法弄清楚发生了什么。
<?php
$invalid = '';
$my_email = 'my@email.com';
// Validate input:
if(empty($_POST['name']) ||
empty($_POST['email']) ||
empty($_POST['message']))
{
$invalid.= "\n All fields are required";
}
$name = $_POST['name'];
$email = $_POST['email'];
$message = $_POST['message'];
// Validate email:
if (!preg_match(
"/^[_a-z0-9-]+(\.[_a-z0-9-]+)*@[a-z0-9-]+(\.[a-z0-9-]+)*(\.[a-z]{2,3})$/i",
$email))
{
$invalid .= "\n Invalid email address";
}
// Send email if no errors detected:
if( empty($invalid))
{
$to = $my_email;
$subject = "Contact form submission: $name";
$body = "You have received a new message. ".
" Here are the details:\n Name: $name \n ".
"Email: $email\n Message:\n $message";
$headers = "From: $email\n";
$headers .= "Reply-To: $email";
mail($to,$subject,$body,$headers);
//redirect to the thank you page:
header('Location: contact_thanks.php');
}
?>
提交后,它会将我带到显示空白且无法重定向的contact_handle.php。
