PHP、フォーム提出後に確認メールを送信する方法

Question

こんにちは、ありがとうございました！

フォーム送信後にカスタムのconfiramtionメールをユーザーに送信したいと思います。

これは私のPHPファイルでどのように設定するのか分かりません。私は非常に初心者です - ごめんなさい質問を申し訳ありません： -/ ありがとう!!

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

    // CHANGE THE TWO LINES BELOW 
    $email_to = "christian@diamond-precision-studio.com"; 

    $email_subject = "website html form submissions"; 


    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['first_name']) || 

     !isset($_POST['email']) || 
     !isset($_POST['budget']) || 
     !isset($_POST['message'])) { 
     died('We are sorry, but there appears to be a problem with the form you submitted.');  
    } 

    $first_name = $_POST['first_name']; // required 

    $email_from = $_POST['email']; // required 
    $budget = $_POST['budget']; // not required 
    $message = $_POST['message']; // required 

    $error_message = ""; 
    $email_exp = '/^[A-Za-z0-9._%-]+@[A-Za-z0-9.-]+\.[A-Za-z]{2,4}$/'; 
    if(!preg_match($email_exp,$email_from)) { 
    $error_message .= 'The Email Address you entered does not appear to be valid.<br />'; 
    } 
    $string_exp = "/^[A-Za-z .'-]+$/"; 
    if(!preg_match($string_exp,$first_name)) { 
    $error_message .= 'The First Name you entered does not appear to be valid.<br />'; 
    } 

    if(strlen($message) < 2) { 
    $error_message .= 'The Comments you entered do not appear to be valid.<br />'; 
    } 
    if(strlen($error_message) > 0) { 
    died($error_message); 
    } 
    $email_message = "Form details below.\n\n"; 

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

    $email_message .= "First Name: ".clean_string($first_name)."\n"; 

    $email_message .= "Email: ".clean_string($email_from)."\n"; 
    $email_message .= "Budget: ".clean_string($budget)."\n"; 
    $email_message .= "Message: ".clean_string($message)."\n"; 


// create email headers 
header("Location: https://www.diamond-precision-studio.com/new-website/thank-you.html"); 

$headers = 'From: '.$email_from."\r\n". 
'Reply-To: '.$email_from."\r\n" . 
'X-Mailer: PHP/' . phpversion(); 
@mail($email_to, $email_subject, $email_message, $headers); 


?> 

<!-- place your own success html below --> 



<?php 
} 
die(); 
?>

このライン：あなたがメール機能を呼び出す前に

header("Location: https://www.diamond-precision-studio.com/new-website/thank-you.html"); 

は別のページにスクリプトをリダイレクトします。つまり、メールは決して実行されません。だから、それを取り除く。
