Cant get included file to connect to database - php

Question

I must be missing something simple but I don't see it. The following code works great.
<?php
$res = mysql_connect("localhost", "newuser", "");
mysql_select_db("supplydb");
function filter($data)
{
$data = trim(htmlentities(strip_tags($data)));
if (get_magic_quotes_gpc())
$data = stripslashes($data);
$data = mysql_real_escape_string($data);
return $data;
}
error_reporting(0);
require("../codebase/grid_connector.php");
$mask5 = filter($_GET["var1"]);
//Get Category ID
$cat = mysql_query("SELECT category FROM submissions WHERE submissions.submission_id='$mask5'");
$rows = mysql_fetch_array($cat, MYSQL_ASSOC);
$array = filter($rows['category']);
//Get Manufactuer ID
$man = mysql_query("SELECT manufacturer_id FROM submissions WHERE submissions.submission_id='$mask5'");
$arows = mysql_fetch_array($man, MYSQL_ASSOC);
$array1 = filter($arows['manufacturer_id']);
function formatting($row)
{
$data = $row->get_value("fda_approved");
if ($data == 1)
$row->set_value("fda_approved", Yes);
else
$row->set_value("fda_approved", No);
}
$gridConn = new GridConnector($res, "MySQL");
function myUpdate($action)
{
$data6 = $action->get_id();
$cat_id = mysql_query("SELECT category FROM submissions WHERE submissions.submission_id ='{$data6}'") or die("Error in query: $query. " . mysql_error());
$rows56 = mysql_fetch_array($cat_id, MYSQL_ASSOC);
$array = filter($rows56['category']);
$status = $action->get_value("approval_status");
$gridConn = new GridConnector($res, "MySQL");
mysql_query("UPDATE submissions SET approval_status='{$status}' WHERE submissions.submission_id='{$data6}'") or die("Error in query: $query. " . mysql_error());
$action->success;
}
$gridConn->event->attach("beforeUpdate", "myUpdate");
$gridConn->event->attach("beforeRender", "formatting");
$gridConn->render_sql("SELECT * FROM submissions JOIN products ON products.product_id = submissions.product_id and submissions.category='$array' and submissions.manufacturer_id='$array1' and submissions.approval_status='0'", "submission_id", "item_number,description,list_price,sugg_price,quantity_per_unit,fda_approved,gpo_contract_number, approval_status");
?>
This code does not
<?php
require("../site_globals/dbc_simple.php");
//$res = mysql_connect("localhost", "newuser", "");
//mysql_select_db("supplydb");
error_reporting(0);
require("../codebase/grid_connector.php");
$mask5 = filter($_GET["var1"]);
//Get Category ID
$cat = mysql_query("SELECT category FROM submissions WHERE submissions.submission_id='$mask5'");
$rows = mysql_fetch_array($cat, MYSQL_ASSOC);
$array = filter($rows['category']);
//Get Manufactuer ID
$man = mysql_query("SELECT manufacturer_id FROM submissions WHERE submissions.submission_id='$mask5'");
$arows = mysql_fetch_array($man, MYSQL_ASSOC);
$array1 = filter($arows['manufacturer_id']);
function formatting($row)
{
$data = $row->get_value("fda_approved");
if ($data == 1)
$row->set_value("fda_approved", Yes);
else
$row->set_value("fda_approved", No);
}
$gridConn = new GridConnector($res, "MySQL");
function myUpdate($action)
{
$data6 = $action->get_id();
$cat_id = mysql_query("SELECT category FROM submissions WHERE submissions.submission_id ='{$data6}'") or die("Error in query: $query. " . mysql_error());
$rows56 = mysql_fetch_array($cat_id, MYSQL_ASSOC);
$array = filter($rows56['category']);
$status = $action->get_value("approval_status");
$gridConn = new GridConnector($res, "MySQL");
mysql_query("UPDATE submissions SET approval_status='{$status}' WHERE submissions.submission_id='{$data6}'") or die("Error in query: $query. " . mysql_error());
$action->success;
}
$gridConn->event->attach("beforeUpdate", "myUpdate");
$gridConn->event->attach("beforeRender", "formatting");
$gridConn->render_sql("SELECT * FROM submissions JOIN products ON products.product_id = submissions.product_id and submissions.category='$array' and submissions.manufacturer_id='$array1' and submissions.approval_status='0'", "submission_id", "item_number,description,list_price,sugg_price,quantity_per_unit,fda_approved,gpo_contract_number, approval_status");
?>
The only difference is the include file at the top and all the include file is is:
<?php
$res = mysql_connect("localhost", "newuser", "");
mysql_select_db("supplydb");
?>
Im fairly new to php but this seems simple and I'm not sure what is getting lost in translation. This works fine on other pages by the way so it must have something to do with the $gridConn = new GridConnector($res, "MySQL"); but I dont know enough to see what. I'm using the DHTMLX javascript library. Could it have something to do with that? Ive tried everything here. Ideas?

Answer 1

Im getting: XML Parsing Error: XML or text declaration not at start of entity Location
Problem is not in the database connection itself, it works correctly and generates data, but result xml corrupted, because some output was started before connector's code.
Check ../site_globals/dbc_simple.php - probably it have some whitespaces|newlines after closing "?>" tag - delete them and it will fix the problem.
Such whitespaces|newlines will not cause harm for HTML pages, but for XML data any extra char at start of document can cause a problem.
