Question

我正在尝试创建一个简单的联系表单。当它成功时，一个div显示在表单上方的成功消息，如果有错误，另一个div显示错误尝试agin。我有下面的代码，我写了我想要代码的地方，我不知道要放什么代码。

感谢您的回复。我尝试了你的建议但它没有用，但这里是我的页面和表格的完整代码。我不介意使用一些ajax或JavaScript，但我对这些语言不太满意。

你现在使用任何javascript来处理表单还是直接的php？您想使用任何类型的javascript（ajax）来处理表单，还是想要传统的表单提交？

如果这是你的所有代码，看起来你只是在使用php。

你会想要这样的东西：

<?php
$output = '';
if ( $_POST['submit'] )
{
    $errors = array();

    if($_POST['name'] == "") {
        $errors[] = true;
    }

    if($_POST['email'] == "") {
        $errors[] = true;
    }

    if(!filter_var($_POST['email'], FILTER_VALIDATE_EMAIL)){
        $errors[] = true;
    }

    if($_POST['subject'] == "") {
        $errors[] = true;
    }

    if($_POST['comment'] == "") {
        $errors[] = true;
    }

    if ($_REQUEST['captcha_entered']!=$_SESSION['rand_code']) { 
        $errors[] = true;
    }

    if(count($errors) == 0) {
        $sendto = "luke@allthingsscene.co";//Your email goes here
        $name = filter_var($_POST['name'], FILTER_SANITIZE_STRING);
        $email = filter_var($_POST['email'], FILTER_SANITIZE_STRING);
        $subject = $_POST['subject'];//You can change your subject here
        $comment = filter_var($_POST['comment'], FILTER_SANITIZE_STRING);

        $message = "<strong>$name</strong> has sent you a message by using the contact form:

       <p><strong>Name:</strong> <em>$name</em></p>

       <p><strong>Email:</strong> <em>$email</em></p>

       <p><strong>The subject:</strong> <em>$subject</em></p>

       <p><strong>Message:</strong> <em>$comment</em></p>";

       $headers = "From: $name <$email> \r\n";
       $headers .= "X-Mailer:PHP/\r\n";
       $headers .= "MIME-Version:1.0\r\n";
       $headers .= "Content-type:text/html; charset=iso-8859-1\r\n";

       if(mail($sendto, $subject, $message, $headers)) {
           $success = true;
       } else {
           $success = false;
       }
    } else {
        $success = false;
    }

    if ($success === true )
    {
        $output .= '<div id="success"><p>Your Success Message Here!</p></div>';
    }
    else
    {
        $output .= '<div id="fail"><p>Your Fail Message Here!</p>';
        $output .= '<ul>';
        for ($i = 0; $i < $errors.length; i++ )
        {
            $output .= '<li>'.$errors[i].'</li>';
        }
        $output .= '</ul>'; 
        $output .= '</div>';
    }

    echo $output;
}
else
{
 ?>

 <div class="container">
     <!-- all of your html "stuff" goes here -->
 </div>

<?php
}

根据联系表单状态隐藏/显示不同的div
