Send email according to input select value - php

Question

I need to make changes to an existing form by adding a dropdown menu where I will have two inputs and their values. The purpose is to send the form to recipient_one if Address 1 is selected or to recipient_two when Address 2 is selected. Address 1 needs to be the default value when nothing is selected.
Here is just the added HTML:
<form method="post" action="./index.php" enctype="multipart/form-data">
<fieldset class="elist">
<legend>Select shop:</legend>
<select name="shop">
<option name="address-chosen" value="Tammsaare" >Tammsaare</option>
<option name="address-chosen" value="Ülemiste" >Ülemiste</option>
</select>
</fieldset>
</form>
and the PHP:
$action = isset($_POST['action']) ? $_POST['action'] : null;
$page = null;
$pages = array('info', 'en');
if( isset($_GET['page']) && in_array($_GET['page'], $pages) ) {
$page = $_GET['page'];
}
if( !in_array($page, $pages) ) {
$page = '';
}
$mail_sent = false;
if( $action == 'add' ) {
//Test if it is a shared client
if (!empty($_SERVER['HTTP_CLIENT_IP'])){
$ip = $_SERVER['HTTP_CLIENT_IP'];
//Is it a proxy address
}elseif (!empty($_SERVER['HTTP_X_FORWARDED_FOR'])){
$ip = $_SERVER['HTTP_X_FORWARDED_FOR'];
}else{
$ip = $_SERVER['REMOTE_ADDR'];
}
$message = '';
$message .= 'Name: '.safe($_POST['name'])."\r\n";
$message .= 'E-mail: '.safe($_POST['email'])."\r\n";
$message .= 'Phone: '.safe($_POST['telephone'])."\r\n";
$message .= 'Mark: '.safe($_POST['mark'])."\r\n";
$message .= 'Model: '.safe($_POST['model'])."\r\n";
$message .= 'Shop: '.safe($_POST['address-chosen'])."\r\n";
$message .= "Wants newsletter: ".$soovib_uudiskirja = isset($_POST['newsletter']) ? "Yes" : "No";
$message .= "\r\n";
$message .= "\r\n";
$message .= "\r\n";
$message .= 'Aeg: '.date('d.m.Y H:i')."\r\n";
$message .= 'IP: '.$ip."\r\n";
$mail_data = array(
'to_email' => 'email#mail.com',
'from_email' => 'email#mail.com',
'from_name' => 'Stock Cars',
'subject' => 'Reservation',
'message' => $message,
);
mail_send($mail_data);
$mail_sent = true;
}
function safe( $name ) {
return( str_ireplace(array( "%0a", "%0d", "Content-Type:", "bcc:","to:","cc:" ), "", $name ) );
}
function mail_send($arr)
{
if (!isset($arr['to_email'], $arr['from_email'], $arr['subject'], $arr['message'])) {
throw new HelperException('mail(); not all parameters provided.');
}
$to = empty($arr['to_name']) ? $arr['to_email'] : '"' . mb_encode_mimeheader($arr['to_name']) . '" <' . $arr['to_email'] . '>';
$from = empty($arr['from_name']) ? $arr['from_email'] : '"' . mb_encode_mimeheader($arr['from_name']) . '" <' . $arr['from_email'] . '>';
$headers = array
(
'MIME-Version: 1.0',
'Content-Type: text/plain; charset="UTF-8";',
'Content-Transfer-Encoding: 7bit',
'Date: ' . date('r', $_SERVER['REQUEST_TIME']),
'Message-ID: <' . $_SERVER['REQUEST_TIME'] . md5($_SERVER['REQUEST_TIME']) . '#' . $_SERVER['SERVER_NAME'] . '>',
'From: ' . $from,
'Reply-To: ' . $from,
'Return-Path: ' . $from,
'X-Mailer: PHP v' . phpversion(),
'X-Originating-IP: ' . $_SERVER['SERVER_ADDR'],
);
mail($to, '=?UTF-8?B?' . base64_encode($arr['subject']) . '?=', $arr['message'], implode("\n", $headers));}
if (isset($_GET['page'])) {}
So the question is how do I reconstruct the array?

Answer 1

Set the email variable based on the form value:
//default is email 1
$email='email#mail.com';
if(isset($_POST['shop']) && $_POST['shop']=='Ülemiste') {$email='email2#mail2.com';}
$mail_data = array(
'to_email' => $email,
'from_email' => $email,
'from_name' => 'Stock cars',
'subject' => 'Reservation',
'message' => $message,
);
edited as per your edit - not sure how the umlaut will effect things though
