From the comments, I can suggest following fixes to your code.

<?php

include("db.php"); 
$city = '';

if(isset($_POST['city']))
{
    $city = $_POST['city'];
    list($localitys, $citys) = explode(' - ', $city, 2); 
    $_SESSION['city'] = $citys;
}

if(isset($_GET['localitys']))
{
    $_SESSION['localitys'] = $localitys;
}

if(isset($_POST['events']))
{
    $_SESSION['event'] = $_POST['events']; 
}
$sql = "";
if(isset($_GET['locality']))
{  
    $sql .= "SELECT * FROM hall_search_data_1 WHERE 1 = 1 ";

    if(isset($_SESSION['city']) && !empty($_SESSION['city']))
        $sql .=  " AND city_name='".$_SESSION['city']."' ";

    if(isset($_SESSION['event']) && !empty($_SESSION['event']))
        $sql .=  " AND hall_evnt_type LIKE '%".$_SESSION['event']."%' ";

    if(isset($_GET['locality']) && !empty($_GET['locality']))
        $sql .=  " AND locality = '".$_GET['locality']."' ";

    mysql_query($sql) or die(mysql_error());
}
else
{
    $sql .= "SELECT * FROM hall_search_data_1 WHERE 1 = 1 ";

    if(isset($_SESSION['city']) && !empty($_SESSION['city']))
        $sql .=  " AND city_name='".$_SESSION['city']."' ";

    if(isset($_SESSION['event']) && !empty($_SESSION['event']))
        $sql .=  " AND hall_evnt_type LIKE '%".$_SESSION['event']."%' ";

    mysql_query($sql) or die(mysql_error());
}

?>

Also try printing $_POST and $_SESSION arrays so that you can come to know whether all parameters are passing/ passing correctly and all the sessions are setting up properly.
