Search an addresbook

Hi All

I am a newby in the php and postgres. I have a the following script that
suppose to search an addrssbook but the scripts does not return anything
even an error. I got this scripts from the internet but in the mysql
form so i changed it to postgres.

The field s for my table is customer_id, name. address, msisdn,
telephone and msisdn. I use want to use name or msisdn to search.
<?php
$dbname = "phonebook";
$host = "localhost";
$port = "5432";
$user = "postgres";

if (!IsSet($start) ) :
$start = 0;
endif;
?>

<?
#if ($searchstring)
if(isset($searchstring) && strcmp("Search",$searchstring) == 0)
{
$query = "SELECT * FROM clientdata WHERE $searchtype LIKE
'%$searchstrin
g%' ORDER BY name ASC";
$connection = pg_connect("host=$host port=$port dbname=$dbname
user=$use
r");
$pg_select_db("$dbname",$query);
$Customer_id = pg_escape_string($_POST['customer_id']);

$Name = pg_escape_string($_POST['name']);
$Msisdn = pg_escape_string($_POST['msisdn']);
$result = pg_query($query);
$resultsnumber = pg_numrows($result);

echo "<TABLE BORDER=0>";
echo "number of results: $resultsnumber";

$alternate = "2";
while ($myrow = pg_fetch_array($result))
{
$Name = $myrow["name"];
$customer_id = $myrow["id"];
$msisdn = $myrow["msisdn"];
if ($alternate == "1")
{
$color = "#ffffff";
$alternate = "2";
}
else
{
$color = "#efefef";
$alternate = "1";
}
echo "<TR bgcolor=$color><TD>$name, $msisdn</TD>";
echo "Could not find records";
}
}
?>
