在javascript表单上恢复数据

Question

最近，我对我的javascript代码进行了更改，只是一个简单的联系表单，也使用了colorbox插件。它启动并运行了5天。在前两天，我收到了来自表单的电子邮件，之后我对代码进行了更改，导致没有收到用户的表单数据。从那时起，我没有收到任何电子邮件。有没有办法仍然检索和恢复从表单发送的数据？

if (isset($_POST['register-form'])) {

    $_POST = array_map('htmlentities', $_POST);

    if ($_POST['type'] == '1') {
        $status = "Professional";
    }

    if ($_POST['type'] == '2') {
        $status = "Student";
    }

    /** Make the mail **/
    $headers = "from: noreply@sample.com\r\n";
    $headers .= 'MIME-Version: 1.0' . "\r\n";
    $headers .= 'Content-type: text/html; charset=iso-8859-1' . "\r\n";

    $subject = "Registration";
    $mail = "<table border='0' width='100%' cellpadding='5' cellspacing='1'>
                <tr>
                    <td witdth='15%'><strong>First Name</strong></td>
                    <td>{$_POST['first-name']}</td>
                </tr>
                <tr>
                    <td><strong>Last Name</strong></td>
                    <td>{$_POST['last-name']}</td>
                </tr>
                <tr>
                    <td><strong>Contact Number</strong></td>
                    <td>{$_POST['contact-number']}</td>
                </tr>
                <tr>
                    <td><strong>E-mail</strong></td>
                    <td>{$_POST['email']}</td>
                </tr>
                <tr>
                    <td><strong>Level</strong></td>
                    <td>{$status}</td>
                </tr>
                <tr>    
                    <td><strong>Company/School</strong></td>
                    <td>{$_POST['company-name']}</td>
                </tr>
            </table>";

    mail('sample91@gmail.com', $subject, $mail, $headers);

}
