php – 不通过电子邮件发送

<h4>Email Al</h4>
<table>
<form name="contactForm" id="contact" action="send_form_email.php" method="post">
    <tr>
    <td>
    <label>Name:</label>
    <input type="text" name="name">
    </td>
    <td>
    <label>Email Address:</label>
    <input type="email" name="email">
    </td>
    </tr>
    <tr>
    <td colspan="2">
    <label>Website (if Available):</label>
    <input type="text" name="website">
    </td>
    </tr>
    <tr>
    <td colspan="2">
    <label>Your Message:</label></br>
    <textarea for="" name="information" width="100%" rows="10" form="contactForm"></textarea>
    </td>
    </tr>
    <tr>
    <td colspan="2">
    <input type="submit" value="Send Message">
    </td>
    </tr>
</form>

这是index.php文件中的表单,下面是send-email.php电子邮件

<?php
  $name = $_POST['name'];
  $email = $_POST['email'];
  $website = $_POST['website'];
  $message = $_POST['information'];

    $email_from = 'myemail@gmail.com';

    $email_subject = $name . " has sent you a message!";

    $email_body = "You have received a new message from " . $name . " via your website!n".
                            "Name:n $namen".
                            "Email:n $emailn".
                            "Website:n $websiten".
                            "Message:n $messagen".



  $to = "clientemail@gmail.com";

  $headers = "From: $email_from rn";

  $headers .= "Reply-To: $visitor_email rn";

  mail($to,$email_subject,$email_body,$headers);


function IsInjected($str)
{
    $injections = array('(n+)','(r+)','(t+)','(%0A+)','(%0D+)','(%08+)','(%09+)'
           );

    $inject = join('|',$injections);
    $inject = "/$inject/i";

    if(preg_match($inject,$str))
    {
      return true;
    }
    else
    {
      return false;
    }
}

if(IsInjected($visitor_email))
{
    echo "Bad email value!";
    exit;
}
?>
<?php
header("Location: /formsubmitted.php"); /* Redirect browser */
exit();
?>

如果有人有任何线索,为什么这是故障,我也很想知道！这是我自己创建的第一个消息/电子邮件php函数之一,因为我通常为wordpress开发,所以我通常只为我的客户端安装一个插件.
