need help with Google Maps API

[svgmx5]

Hey everyone

 

i'm working with google maps and i'm having a small problem...

 

the problem is that i have records on my database that i'm echoing using php and mysql and i want to display those items on the map as well. I have the lat and lon of them .

 

The problem is that i also want the users to search for the items and then those items will be displayed based on what the user searched for however i'm using some code from google maps API sample code gallery and i'm having problems parsin the values from the form to the seperate script that displays them results in XML format

 

This is the script i'm suing

 

http://code.google.com/apis/maps/articles/phpsqlajax_v3.html

 

And below i have the code

<?php
require("phpsqlajax_dbinfo.php");

// Start XML file, create parent node
$doc = domxml_new_doc("1.0");
$node = $doc->create_element("markers");
$parnode = $doc->append_child($node);

// Opens a connection to a MySQL server
$connection=mysql_connect (localhost, $username, $password);
if (!$connection) {
  die('Not connected : ' . mysql_error());
}

// Set the active MySQL database
$db_selected = mysql_select_db($database, $connection);
if (!$db_selected) {
  die ('Can\'t use db : ' . mysql_error());
}

// Select all the rows in the markers table
$query = "SELECT * FROM markers WHERE 1";
$result = mysql_query($query);
if (!$result) {
  die('Invalid query: ' . mysql_error());
}

header("Content-type: text/xml");

// Iterate through the rows, adding XML nodes for each
while ($row = @mysql_fetch_assoc($result)){
  // ADD TO XML DOCUMENT NODE
  $node = $doc->create_element("marker");
  $newnode = $parnode->append_child($node);

  $newnode->set_attribute("name", $row['name']);
  $newnode->set_attribute("address", $row['address']);
  $newnode->set_attribute("lat", $row['lat']);
  $newnode->set_attribute("lng", $row['lng']);
  $newnode->set_attribute("type", $row['type']);
}

$xmlfile = $doc->dump_mem();
echo $xmlfile;

?>

 

Obviously i'm  using my own rows and info.

 

So my question is how can i get the post variables from the form which are stored in one page to get them to echo in the page above with the script so it can search for the values

 

I've tried using $_SESSION[] but its not wokrking, nothing is being parsed, and yes i did add session_start() at the top of the page
