Need city/state snippet for contact form - php

Question

My PHP contact form is working correctly and outputs all info including senders IP address in the subsequent e-mail. I'm having trouble coding the PHP form to also receive the sender's city and state in the email that the form generates.
I've tried several code snippets, but the most I get is the city and state output on the web page above the form. I need it in the email instead. Looking for a free service.
PHP form
<?php
include 'contact_config.php';
session_start();
error_reporting (E_ALL ^ E_NOTICE);
$post = (!empty($_POST)) ? true : false;
if($post)
{
include 'functions.php';
$name = stripslashes($_POST['name']);
$email = trim($_POST['email']);
$level = stripslashes($_POST['level']);
$age = stripslashes($_POST['age']);
$drums = stripslashes($_POST['drums']);
$referral = stripslashes($_POST['referral']);
$city = json_decode(file_get_contents("http://ipinfo.io/{$ip}"));
$subject = " Website Inquiry";
$message = "
Name: ".$_POST['name']
."
E-mail Address: ".$_POST['email']
."
Level: ".$_POST['level']
."
Age: ".$_POST['age']
."
Drums: ".$_POST['drums']
."
Referral: ".$_POST['referral']
."
Message: ".$_POST['content']
."
City: ".$_POST['city']
."
IP Address: ". $_SERVER['REMOTE_ADDR'];
$error = '';
// Check name
if(!$name)
{
$error .= 'Please enter your name.<br />';
}
// Check email
if(!$email)
{
$error .= 'Please enter an e-mail address.<br />';
}
if($email && !ValidateEmail($email))
{
$error .= 'Please enter a valid e-mail address.<br />';
}
if(isset($_SESSION['captcha_keystring']) && strtolower($_SESSION['captcha_keystring']) != strtolower($_POST['captcha']))
{
$error .= "Incorrect captcha numbers.<br />";
}
if(!$error)
{
$mail = mail(WEBMASTER_EMAIL, $subject, $message,
"From: ".$name." <".$email.">\r\n"
."Reply-To: ".$email."\r\n"
."X-Mailer: PHP/" . phpversion());
if($mail)
{
echo 'OK';
}
}
else
{
echo '<div class="notification_error">'.$error.'</div>';
}
}
?>

Look at this part of your code:
$message = "
Name: ".$_POST['name']
."
E-mail Address: ".$_POST['email']
."
Level: ".$_POST['level']
."
Age: ".$_POST['age']
."
Drums: ".$_POST['drums']
."
Referral: ".$_POST['referral']
."
Message: ".$_POST['content']
."
City: ".$_POST['city']
."
IP Address: ". $_SERVER['REMOTE_ADDR'];
You are concatting Variables to a new Variable. Just add $_POST['state'] or how you called these fields, to this large Variable. Because you already added $_POST['city'].
So if it is not showing in the email, the Fields you are sending, are named differently.
