Utf-8 Encoding for Subject in Contact Form Email

UTF-8 encoding for subject in contact form email

here is how i did it:

$head = "From: \"=?ISO-8859-15?Q?".imap_8bit("äöüßÄÖÜ sollte hier gehen")."?=\" <info@mydomain.de>\n";
$subject = "=?ISO-8859-15?Q?".imap_8bit("äöüßÄÖÜ sollte hier gehen")."?=";
mail($mail,$subject,$text,$head);

that is ofc just Latin-15 (German) encoding. utf-8 works the same way:
look here for a great explanation on how to use character encoding in mail headers:
http://ncona.com/2011/06/using-utf-8-characters-on-an-e-mail-subject/

for your code you have to change this in the sendmail class:

if (mail($this->to, '=?utf-8?B?'.base64_encode($this->subject).'?=', $this->body, $this->headers))

! this only works properly if your php file is utf-8 encoded !

still very annoying. then i switched to phpmailer. that does everything for you. way more easy. i would suggest you use that.

Special characters (utf-8) in PHP contact message

Since you're using UTF-8, consider using php multibyte functions link mb_*. For example:

echo strlen('è'); // output 2
echo mb_strlen('è', 'UTF-8'); // output 1

Other mb_* functions you might be interested in:

strrpos() to mb_strrpos()

substr() to mb_substr()

For full list of multibyte functions, look here.

If you don't want to pass 'UTF-8' in every mb_ function, call mb_internal_encoding('UTF-8') in the beginning of your script.

For the mail() function to work properly with UTF-8, pass the following in the header:

$header = "Content-Type: text/html; charset=UTF-8"

Charset UTF-8 not working on ?php contact form

You aren't setting the mail header there, you are setting the http header. This function header is sending a raw HTTP header, it isn't doing anything for the email you are sending

   header('Content-Type: text/html;charset=UTF-8');

You need to add the header "Content-Type: text/html; charset=UTF-8" (for HTML Email bodies) or "Content-Type: text/plain; charset=UTF-8" (for Plain Text Email bodies) to your mail function. Like this.

$headers = array("Content-Type: text/html; charset=UTF-8");
mail($to, $subject, $message, $headers)

Additionally, for email, each lines should be separated with a CRLF (\r\n) instead of merely using a linefeed (\n). A fully example end result might look more so like this:

<?php

    $crlf = "\r\n";

    //Get Data
    $name = strip_tags($_POST['name']);
    $email = strip_tags($_POST['email']);
    $service = strip_tags($_POST['service']);
    $phone = strip_tags($_POST['phone']);
    $phoneconfirm = strip_tags($_POST['phoneconfirm']);
    $priority = strip_tags($_POST['priority']);
    $subject = strip_tags($_POST['subject']);
    $message = strip_tags($_POST['message']);

    // Parse/Format/Verify Data
    $to      = "THETOEMAIL@GOES.HERE";
    $from    = 'THEFROMEMAIL@GOES.HERE';
    $subject = "Via Website";
    $message = "De: $name$crlf E-Mail: $email$crlf Serviço: $service$crlf
         Telefone/Celular: $phone$crlf Ligar/Retornar: $phoneconfirm$crlf 
         Prioridade: $priority$crlf Assunto: $subject$crlf Mensagem:$crlf 
         $message";

    // Setup EMAIL headers, particularly to support UTF-8
    // We set the EMAIL headers here, these will be sent out with your message
    // for the receiving email client to use.
    $headers = 'From: ' . $from  . $crlf .
               'Reply-To: ' . $from  . $crlf .
               'Content-Type: text/plain; charset=UTF-8' .  $crlf .
               'Para: WebSite'  .  $crlf .
               'X-Mailer: PHP/' . phpversion();

    // Then we pass the headers into our mail function
    mail($to, $subject, $message, $headers);
?>

• header function
