Form Validation -> Codeigniter

PHP
1

Hello,

I am unsure why the below code is not outputting my validation errors (the login page works fine)

if ( ! defined('BASEPATH')) exit('No direct script access allowed');

class Addsale extends CI_Controller { 

    function __construct(){ 
    parent::__construct(); 
    } 
    function index() { 
    if(!$this->session->userdata('logged_in')) { 
        redirect('admin/home'); 
    } 
    // Main Page Data 
    $data['cms_pages'] = $this->navigation_model->getCMSPages(); 
    $data['title'] = 'Add Sale'; 
    $data['content'] = $this->load->view('admin/addsale',NULL,TRUE); 
     
    $this->load->view('admintemplate', $data); 

    //Set Validation 
    $this->form_validation->set_rules('name', 'Name', 'trim|required'); 
    $this->form_validation->set_rules('location', 'Location', 'trim|required'); 
    $this->form_validation->set_rules('bedrooms', 'Bedrooms', 'trim|is_natural|required'); 
    $this->form_validation->set_rules('bathrooms', 'Bathrooms', 'trim|is_natural|required'); 
    $this->form_validation->set_rules('condition', 'Condition', 'trim|required'); 
    $this->form_validation->set_rules('description', 'Description', 'trim|required'); 
    $this->form_validation->set_rules('price', 'Price', 'trim|required'); 

    if($this->form_validation->run() === TRUE) { 
    
    //Set File Settings 
    $config['upload_path'] = './includes/uploads/'; 
    $config['allowed_types'] = 'jpg|png'; 
    $config['max_size'] = '100'; 
    $config['max_width'] = '1024'; 
    $config['max_height'] = '768'; 

    $this->load->library('upload', $config); 
    
    $this->upload->do_upload();
	$file_info = $this->upload->data();
     
    $data = array(   
        'name' => $this->input->post('name', TRUE), 
        'location' => $this->input->post('location', TRUE), 
        'bedrooms' => $this->input->post('bedrooms', TRUE), 
        'bathrooms' => $this->input->post('bathrooms', TRUE), 
        'condition' => $this->input->post('condition', TRUE), 
        'description' => $this->input->post('description', TRUE), 
        'price' => $this->input->post('price', TRUE), 
        'image' => $file_info['full_path'] 
        ); 
    $this->sales_model->addSale($data); 
    } 
 } 

}
