Need help with the new form validation

[eluser]Unknown[/eluser]
Hi need help with populated form when getting data from database using the new form validation in CI 1.7.1 ...

This is the code in the controller ...

Code:

$query = $this->product->_get_product_detail_by_id($id);
        if ($query->num_rows() >=1 )
        {    
            $row = $query->row();
        
            $data['quick_link'] = '<div class="full_area" style="line-height:33px;" align="left">
            <span style="color:grey;"><b>Quick Links :</b></span><span style="color:#8ab00f;"><b> <a href="'.base_url().'index.php/administrator/product/add">Add Product</a></b></span></div>';
                    
            $this->load->library('form_validation');
            
            $this->form_validation->set_rules('category', 'Product Category', 'trim|required|xss_clean');
            $this->form_validation->set_rules('name', 'Product Name', 'trim|required|xss_clean');
            $this->form_validation->set_rules('description', 'Product Description', 'trim|required|xss_clean');
            
            $config['upload_path'] = './tmp/';
            $config['allowed_types'] = 'gif|jpg|png';
            $config['max_width']  = '1024';
            $config['max_height']  = '768';
            
            $this->load->library('upload', $config);
                    
            if ($this->form_validation->run() == FALSE || !$this->upload->do_upload())
            {
                
                $data['error'] = $this->upload->display_errors();
                
                //How to Pass the data from database to the form view
                
                $this->load->view('backend/product_detail', $data);
            }
            else
            {
                
                $category = $this->input->post('category', TRUE);
                $name = $this->input->post('name', TRUE);
                $description = $this->input->post('description', TRUE);
                
                $upload = $this->upload->data();
                $ext = $upload['image_type'];
                $thumbs = './public/images/product/'.$upload['raw_name'].'.jpg';
                
                $this->cropImage('250', '250', $upload['full_path'], $ext, $thumbs);
                unlink($upload['full_path']);
                
                $file_path = 'public/images/product/'.$upload['raw_name'].'.jpg';
    
                // insert input data into database            
                $data_input = array (
                    'product_category' => $category,
                    'product_name' => $name,
                    'product_description' => $description,
                    'product_avatar' => $file_path
                );
                
                $this->product->_update_product_detail($id, $data_input);
                
                $this->load->view('backend/success', $data);
            }    
        }else{
            redirect('','location');
        }
