PHP updating images

Not sure if you think we are wizards, but it might be helpful if you show us some of your code and tell us what packages you are using... Just so we can help you :)

@mthomas I know you guys are wizards, as this forum has helped me a lot in my small programming career.

Here is the code :

function addProductsData($data){
    if($data['id']!=''){
        $sql = "Select * from `product_details` where id = " . $data['id'];
        $tempData =  $this->CommonClass1->ResultWithArrayData($sql);
        // echo "<pre>"; var_dump($tempData);exit;
        if(isset($_FILES['image']['name']) && !empty($_FILES['image']['name']) && $_FILES['image']['name']!=''){    
            $countfiles = count($_FILES['image']['name']);
            $temp = '';
            for($i=0;$i<$countfiles;$i++){
                $uploadpic=date('Y_m_d_h_i_s').'_'.str_replace(' ', '',$_FILES['image']['name'][$i]);
                move_uploaded_file($_FILES['image']['tmp_name'][$i],'uploads/products/'.$uploadpic);
                $temp = $temp . $uploadpic . '#';
            }
            $tempImageName = $tempData[0]['image'] . $temp;
            $sql = "UPDATE `product_details` SET `heading`='".$data['heading']."',`message`='".$data['message']."',`description`='".$data['description']."',`additional`='".$data['additional']."',`image`='".$tempImageName."' WHERE id=".$data['id']."";
            $status =  $this->CommonClass1->NormalQuery($sql);
            return $status;
        }else{
             ;
        }
    }
    else{
        if(isset($_FILES['image']['name']) && !empty($_FILES['image']['name'])){    
            $countfiles = count($_FILES['image']['name']);
            $temp = '';
            for($i=0;$i<$countfiles;$i++){
                $uploadpic=date('Y_m_d_h_i_s').'_'.str_replace(' ', '',$_FILES['image']['name'][$i]);
                move_uploaded_file($_FILES['image']['tmp_name'][$i],'uploads/products/'.$uploadpic);
                $temp = $temp . $uploadpic . '#';
            }
            $data['image']=$temp;
        } 
        return $this->CommonClass1->NormalQuery("INSERT INTO `product_details`(`heading`,`message`,`image`,`description`,`additional`) VALUES ('".$data['heading']."','".$data['message']."','".$data['image']."','".$data['description']."','".$data['additional']."') ");
    }
}
