PHP form sendeail.php not identifying new form items - php

Question

I am trying to add new items to a legacy sendeail.php form. However, when I add the new items to the php listing and the mail delivery, they aren't displaying at all in the email that is sent. At least the emails are going through... I know that I need to refine the radio and check box items, but NONE of the new items are showing. New items are all items after $attn in the code list immediately below. Any and all help is appreciated, thank you very much!
My PHP code is:
<?php
$ip = $_POST['ip'];
$httpref = $_POST['httpref'];
$httpagent = $_POST['httpagent'];
$visitor = $_POST['visitor'];
$visitormail = $_POST['visitormail'];
$notes = $_POST['notes'];
$attn = $_POST['attn'];
$phone = $_POST['phone'];
$interest = $_POST['interest'];
$budget = $_POST['budget'];
$budget = $_POST['day'];
$timeslot = $_POST['timeslot'];
if (eregi('http:', $notes)) {
die ("Do NOT try that! ! ");
}
if(!$visitormail == "" && (!strstr($visitormail,"#") || !strstr($visitormail,".")))
{
echo "<h2>Use Back - Enter valid e-mail</h2>\n";
$badinput = "<h2>Please complete all the fields.</h2>\n";
echo $badinput;
die ("Use the Back button on your browser...");
}
if(empty($visitor) || empty($visitormail) || empty($notes ) || empty($attn ) || empty($phone )) {
echo "<h2>Please click Back and fill in all fields.</h2>\n";
die ("Use the Back button on your browser... ");
}
$todayis = date("l, F j, Y, g:i a") ;
$attn = $attn ;
$subject = $attn;
$notes = stripcslashes($notes);
$message = " $todayis [EST] \n
Web Site Request About: $attn \n
From: $visitor ($visitormail)\n
Phone: $phone \n
Message: $notes \n
Interested In: $interest \n
Heating Budget: $budget \n
Time Availability: Days - $day \n
Time Availability: Morning or Afternoon - $timeslot \n
Additional Info : IP = $ip \n
Browser Info: $httpagent \n
Referral : $httpref \n
";
$from = "From: $visitormail\r\n";
mail("XXXXX", $subject, $message, $from);
?>
And my HTML code is:
<?php
$ipi = getenv("REMOTE_ADDR");
$httprefi = getenv ("HTTP_REFERER");
$httpagenti = getenv ("HTTP_USER_AGENT");
?>
<input type="hidden" name="ip" value="<?php echo $ipi ?>" />
<input type="hidden" name="httpref" value="<?php echo $httprefi ?>" />
<input type="hidden" name="httpagent" value="<?php echo $httpagenti ?>" />

Answer 1

First of all: always validate input (POST). You've got some basic validation already but read up on the security implications regarding POST data.
Array keys in php are case sensitive. $_POST['phone'] is not the same as $_POST['Phone'].
Your select tags are broken, take a look at the colouring in your posted html.
You have declared $budget twice, overwriting the intended data:
$budget = $_POST['budget'];
$budget = $_POST['day'];
checkboxes should be arrays when posted, change the name attribute to thename[] instead of just thename. Of course your php script must handle the resulting array after this change.
