$errors = array('error' => $this->upload->display_errors());
$img="";
}

$content = $this->input->post('description');
$status = $this->input->post('status');
$this->db->where('product_id', $id);
$this->db->update('products',array('product_name'=>$title,'product_content'=>$content,'product_image'=>$img,'product_file'=>$pdf,'product_status'=>$status));
$this->db->where('product_id',$id);
$this->db->delete('products_filter');
$filters= $_POST['filter'];
foreach ($filters as $value)

Please check my code
this code to handle pdf or images file upload in different directory
<?php
if($_POST){
if($_FILES['productimage']['name'])
{
$custom_file_name = $_FILES['productimage']['name'];
$file_ext = end(explode('.', $custom_file_name));
if($file_ext=='pdf')
{
$upload_path_directory='./uploads/products/pdf/';
$file_field_name="productimage";
}
else{
$upload_path_directory='./uploads/products/images/';
$file_field_name="productpdf";
}
$config['upload_path'] = $upload_path_directory;
$config['allowed_types'] = 'png|jpg|gif|bmp|pdf';
$config['overwrite'] = TRUE;
$this->load->library('upload',$config);
if(!$this->upload->do_upload("$file_field_name"))
{
$errors = array('error' => $this->upload->display_errors());
$custom_file_name="";
}
else
{
$data =$this->upload->data();
$custom_file_name=$data['file_name'];
}
?>
First to make sure to upload library libraries and form validation if don't know where to set libaray will mention below*
$this->load->libaray("upload");
$this->load->libaray("form_validation");
to add this code in if condition
