Why isn`t this code working?

[djfox]

First the background story:

I`ve had this strip of coding working for several months, never touched it. The server host has changed something where all of my codes went into a seizure and no longer work so I`ve had to rebuild my site to get everything to work.

 

The code that needs looking over:

<?php
session_start();

include("dbcon.php");
include("func.php");
require_once "auth.php";
require_once "design.php";

if (!isLoggedIn()) {
Redirect("index.php");
}

if ($lev > 0) {
$log = $_SESSION['sess_name'];
$id = $_POST['id'];
$p = $_POST['p'];
$pr = $_POST['pr'];
$s = $_POST['s'];
$it = $_POST['it'];
$n = $_POST['n'];

$res3 = mysql_query("Select id,login,echo_count FROM userdata WHERE id='$s'")or die( mysql_error() );
$sel = mysql_fetch_row($res3);
mysql_free_result($res3);

if ($_SESSION['echos'] >= $p) {

$res = mysql_query("SELECT id,seller,item,sellprice,price,sellerid FROM coll_sell WHERE id=$id");
$chap = mysql_fetch_row($res);
mysql_free_result($res);

$_SESSION['echos'] = $echos = $echos - $chap[3];

   mysql_query("UPDATE userdata SET echo_count='$echos' WHERE id='$logged' ") or die(mysql_error());
   
mysql_query("INSERT INTO sales (seller,buyer,item,echos) VALUES ( '$sel[1]', '$log', '$n', '$p' )");

mysql_query("INSERT INTO coll_inven (user,item,price) VALUES ( '$log', '$it', '$pr' )");
mysql_query("DELETE FROM coll_sell WHERE id=$id");

$entry_date = strftime("%B\ %e\,\ %Y %H:%M:%S", time());
   mysql_query("INSERT INTO trace_history3 (user,date,action,amount) VALUES ( '$log', '$entry_date', 'Bought $n', '$p' )")or die ( mysql_error());
   
header("Location: trancershop.php?g=$sel[0]");
}
else {
header("Location: trancershop.php?g=$s&alert=noechos");
}
}
else {
header("Location: today.php");
}
?>

 

What the code is supposed to do:

In short, it is a virtual transaction.

The item is removed from the sales table, item is added to buyer`s inventory, the amount of echos (currency) the seller marks the item for should be removed from buyer`s echos amount and put the amount in sales for the buyer to pick up.

 

What the code is currently doing:

It will remove the item from the sales table, it is entering the item into the buyer`s inventory, the amount is entered into sales for seller to pick up, however the amount is not being correctly removed from the buyer`s echos.

 

What I have done:

I`ve echo`ed out all the information and the information being transferred through the form for the transaction is correct and all of the info is being picked up by the code. I`ve re-written the line of codes involving the removal of the ehcos amount from the buyer`s amount and have two different results: 1) the buyer`s echos remain the same 2) the buyer`s echos change to the negative amount of what $p is instead of just simple subtraction

 

References:

The following line of code

   $_SESSION['echos'] = $echos = $echos + 10;
   mysql_query("UPDATE userdata SET echo_count='$echos' WHERE id='$logged' ") or die(mysql_error());

is used in another file where echos are being added to the user`s echos amount and this works perfectly fine. I post this because some people have issues with how I write the code for math calculations of the echos and claim it doesn`t work, however I have files where it does work, and this had worked for months.

 

Additional info:

$logged is defined in design.php which I am not posting because that is not the problem.

 

I think that`s all the info needed.

I have found that including header.php made it work:

<title><? echo $Title ?></title>
<style type="text/css">
<!--
input { font-family: Verdana, Arial, Helvetica, sans-serif; font-size: 13px; color: #B6ABCE; text-decoration: none; background-color: #000000; border-top-width: 0px; border-right-width: 0px; border-bottom-width: 0px; border-left-width: 0px}
}
-->
</style>

else {

	echo "<table border=0 width=100% bgcolor='000000'><tr><td background='$boxbanner'><b>Read-Only Mode</b>";
	echo "<tr><td background='$boxback'>";
	echo "Secret Trance is in read-only mode for maintenance. Check back in a few minutes.";
	echo "</table>";
}
}
?>

 

Though I don`t understand why not having header.php was preventing the code from operating.
