PHP won't submit list selection - php

Question

I have been using a mail form successfully until I changed the "state" field from a text field to a select/list. Now the php will not send the contents of the "state Field." Do I need to revise the PHP to accommodate the different type of field? Heres the PHP.
PHP:
<?php
if(isset($_POST['email'])) {
// EDIT THE 2 LINES BELOW AS REQUIRED
$email_to = "pecraig#moneymovers.com";
$email_subject = "OBM/Mailing List Form";
function died($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($_POST['last_name']) ||
!isset($_POST['email']) ||
!isset($_POST['telephone']) ||
!isset($_POST['company']) ||
!isset($_POST['street']) ||
!isset($_POST['city']) ||
!isset($_POST['state']) ||
!isset($_POST['zip'])) {
died('We are sorry, but there appears to be a problem with the form you submitted.');
}
$first_name = $_POST['first_name']; // required
$last_name = $_POST['last_name']; // required
$email_from = $_POST['email']; // required
$telephone = $_POST['telephone']; // required
$company = $_POST['company']; // required
$street = $_POST['street']; // required
$city = $_POST['city']; // required
$state = $_POST['state']; // required
$zip = $_POST['zip']; // required
$error_message = "";
$string_exp = "/^[A-Za-z0-9 .'-]+$/";
if(!preg_match($string_exp,$first_name)) {
$error_message .= 'The First Name you entered does not appear to be valid.<br />';
}
if(!preg_match($string_exp,$last_name)) {
$error_message .= 'The Last Name you entered does not appear to be valid.<br />';
}
$email_exp = '/^[A-Za-z0-9._%-]+#[A-Za-z0-9.-]+\.[A-Za-z]{2,4}$/';
if(!preg_match($email_exp,$email_from)) {
$error_message .= 'The Email Address you entered does not appear to be valid.<br />';
}
if(!preg_match($string_exp,$telephone)) {
$error_message .= 'The Telephone Number you entered does not appear to be valid.<br />';
}
if(strlen($error_message) > 0) {
died($error_message);
}
$email_message = "This is Response from OBM/Mailing List Page. If only the first four fields are filled it is a request for an OBM demo - please contact. If all fileds are filled please contact and enter in database.\n\n";
function clean_string($string) {
$bad = array("content-type","bcc:","to:","cc:","href");
return str_replace($bad,"",$string);
}
$email_message .= "First Name: ".clean_string($first_name)."\n";
$email_message .= "Last Name: ".clean_string($last_name)."\n";
$email_message .= "Email: ".clean_string($email_from)."\n";
$email_message .= "Telephone: ".clean_string($telephone)."\n";
$email_message .= "Company: ".clean_string($company)."\n";
$email_message .= "Street: ".clean_string($street)."\n";
$email_message .= "City: ".clean_string($city)."\n";
$email_message .= "State: ".clean_string($state)."\n";
$email_message .= "Zip: ".clean_string($zip)."\n";
// create email headers
$headers = 'From: '.$email_from."\r\n".
headers = 'Cc: info#moneymovers.com'."\r\n";
'Reply-To: '.$email_from."\r\n" .

Answer 1

EDIT:
Try changing the name of your <select> list from "State" to "state". Capitalization matters.
I retract my original answer below.
Apparently "If it is not defined, its default value is the text content of the element."
https://developer.mozilla.org/en-US/docs/Web/HTML/Element/option
ORIGINAL (obsolete):
You'll need to give your <select> list a name and the <option> some values:
<select name="state">
<option value="AL" selected>AL</option>
...
</select>
EDIT:
Also, when building email headers, you seem to be mixing concatenation with direct variable definitions.
Try:
$headers = 'From: '.$email_from."\r\n" .
'Cc: info#moneymovers.com'."\r\n" .
'Reply-To: '.$email_from."\r\n" .
'X-Mailer: PHP/' . phpversion();
OR
$headers = 'From: '.$email_from."\r\n";
$headers .= 'Cc: info#moneymovers.com'."\r\n";
$headers .= 'Reply-To: '.$email_from."\r\n";
$headers .= 'X-Mailer: PHP/' . phpversion();
