i have been trying this script from morninig and i didn know why it doesnt work?
i have it working in smarty but when i try to take the same code and put it in one php file it never works

the database works,as i enter the add link or image in to the city tables as id's
for example Paris has (1|2|3|4)
and this is the id's of the banner added in another table
this is the code
PHP Code:
<?php
    require('lib/load_configuration.php');
    
    //$smarty->assign('test','saurabh');
    $city=1;
    if(isset($_GET['cty']))
    {
        $city=$_GET['cty'];
    }
    

    
    $cities=array();
    $query="select * from vz_cities_tbl  where VCI_ID='".$city."'";
    echo $query;
    $result=mysql_query($query);
    if(mysql_num_rows($result)>0)
    {
        $city=mysql_fetch_array($result);
        
        $topBanners=explode('|',$city['VCI_Top_Banner']);
        

        $cnt=0;
        
        foreach($topBanners as $topBanner)
        {
            $query="select VB_File,VB_Link,VB_Type from vz_banner_tbl where VB_ID='".$topBanner."'";
            $result=mysql_query($query);
            $row=mysql_fetch_array($result);
            $city['VB_File'][]=$row['VB_File'];
            $city['VB_Link'][]=$row['VB_Link'];
            $city['VB_Type'][]=$row['VB_Type'];            
        
            if($row['VB_Type']=='1')
            {    
                $tempImg='<img src="admin/uploaded_files/banner/'.$row['VB_File'].'" border="0" />';
                $jsTopBanners.=$tempImg;
                
            }
        
            elseif($row['VB_Type']=='2')
            {
                $jsTopBanners.="slides[".$cnt."]='".$row['VB_File']."';";
            }
            $cnt++;                        
        }
    print_r($jsTopBanners);    
            
    }
?>
