我的PHP電子郵件腳本不工作？

Question

所以我做了一個發送電子郵件的腳本，它使用了post方法，因爲它使用另一種編寫信息的編程語言，並且php接收併發送它。現在這個工作一直持續到幾個嘗試後，它還沒有發送？沒有收到任何東西，我不記得改變它。

這裏是腳本：

<?php 
if(isset($_POST['username'])) { 

    function died($error) { 
     // your error code can go here 
     echo "We are very sorry, but there were error(s) found with the form you submitted. "; 
     echo "These errors appear below.<br /><br />"; 
     echo $error."<br /><br />"; 
     echo "Please go back and fix these errors.<br /><br />"; 
     die(); 
    } 

    // validation expected data exists 
    if(!isset($_POST['username']) || 
     !isset($_POST['emailto']) || 
     !isset($_POST['emailsubject']) || 
     !isset($_POST['emailmessage'])) { 
     died('We are sorry, but there appears to be a problem with the form you submitted.');  
    } 

    $username = $_POST['username']; // required 
    $emailto = $_POST['emailto']; // required 
    $emailsubject = $_POST['emailsubject']; // required 
    $emailmessage = $_POST['emailmessage']; // required 

    $error_message = ""; 
    $string_exp = "/^[A-Za-z .'-]+$/"; 
    if(!preg_match($string_exp,$username)) { 
    $error_message .= 'The Name you entered does not appear to be valid.<br />'; 
    } 
    if(strlen($comments) < 2) { 
    $error_message .= 'The Comments you entered do not appear to be valid.<br />'; 
    } 
    if(strlen($emailsubject) < 2) { 
    died($error_message); 
    } 
    if(strlen($emailmessage) < 2) { 
    died($error_message); 
    } 

    $email_message = "This information was sent by a computercraft user:\n\n"; 

    function clean_string($string) { 
     $bad = array("content-type","bcc:","to:","cc:","href"); 
     return str_replace($bad,"",$string); 
    } 


    $email_message .= "Username: ".clean_string($username)."\n"; 
    $email_message .= "Subject: " .clean_string($emailsubject)."\n"; 
    $email_message .= "Message: \n".clean_string($emailmessage)."\n"; 


// create email headers 
$headers = 'From: ' . $username . "\r\n". 
'Reply-To: '.$username."\r\n" . 
'X-Mailer: PHP/' . phpversion(); 
mail($emailto, $emailsubject, $email_message, $headers); 
?> 

{ 
    "True", 
} 

<?php 
} 
?> 

Array 

（ [型] => 8 [消息] =>未定義變量：評論 [文件] => /客戶/ C/5/1/dannysmc .com/httpd.www/ccdb/email.php [line] => 31 ）

// mail（$ emailto，$ emailsubject，$ email_message，$ headers）;
？>

{ 「真」， }

我在底部爲被接收它需要該類型表的程序添加一個真正的表。

如果你能幫助將是巨大的，感謝

變化的代碼的東西你最後一部分這樣的瞭解更多有關該錯誤

//創建電子郵件標題

$headers = 'From: your-email-address'."\r\n". 
'Reply-To: your-email-address'."\r\n" . 
'X-Mailer: PHP/' . phpversion(); 
if(mail($emailto, $emailsubject, $email_message, $headers)){ 
    echo 'TRUE'; 
}else{ 
    echo '<pre>'; 
    print_r(error_get_last()); //it will show you the error. Remove it on production 
} 
?>
