I am doing a project where I want dropdown selection based autocomplete values in textbox.

My index.php coding:

XML

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<title></title>
<link rel="stylesheet" type="text/css" href="jquery.autocomplete.css" />
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.8.0/jquery.min.js"></script>
<script type="text/javascript" src="jquery.js"></script>
<script type="text/javascript" src="jquery.autocomplete.js"></script>
<script type="text/javascript" src="jquery-1.3.2.min.js"></script>
<script>
$(document).ready(function(){
 $("#tag").autocomplete("autocomplete.php", {
        selectFirst: true
    });
});
</script>
<script>
   $(document).ready(function() {
      $("#city").change(function(){
          var city = $("#city").val();
          $("#stage").load('autocomplete.php', {"city":city} );
      });
   });
</script>
</head>
<body>
<div>Select City</div>
<select id="city" name="city">
<option value="select">Select</option>
<option value="Chennai">Chennai</option>
<option value="Madurai">Madurai</option>
<option value="Salem">Salem</option>
<option value="Trichy">Trichy</option>
</select><br />
<input type="text" id="tag" class="tag" size="20" /><br />
<div id="stage">
</div>
</form>
</body>
</html>

In index page on selecting city the value is passed to autocomplete.php using jquery.

my autocomplete.php coding:

PHP

<?php
if($_REQUEST["city"])
{
   $city = $_REQUEST['city'];
}
?>
<?php
echo $city;
$q=$_GET['q'];
$my_data=mysql_real_escape_string($q);
$mysqli=mysql_connect('localhost', 'root', '');
if (!$mysqli)
{
   die('Could not connect: ' . mysql_error());
}
if(!mysql_select_db("details"))
{
  die('Could not connect database: ' . mysql_error());
}
    $sql="SELECT localty FROM localty where localty like '%$my_data%' and city='$city'";
    $result = mysql_query($sql);

    if($result)
    {
        while($row=mysql_fetch_array($result))
        {
            echo $row['localty']."\n";
        }
    }
?>

on changing the city value in autocomplete.php the value is displayed but entering firstletter in textbox for autocomplete the city is not displaying.

Any Suggestions Please.
