Codeigniter blog application bug: form is loaded without validation errors

You need to combine edit and update. If you look at my example below I'm saving it inside run() and loading the form inside "else".

PHP Code:

public function update( $group_id )
{
    $this->VALID_UUIDv4($group_id);
    
    $this->data['group'] = $this->group_model->get($group_id);
    if( empty($this->data['group']) ) { show_404(); }
    if( $this->data['group']->company_id !== $this->auth_company_id ) { show_404(); }
    
    $this->load->helper('form');
    $this->load->library('form_validation');
    $this->config->load('form_validation');
    $validation_rules = $this->_get_rules_update();
    
    $this->form_validation->set_rules( $validation_rules );
    if( $this->form_validation->run() === TRUE )
    {
        if ( $this->group_model->update( $this->data['group'] ) === TRUE )
        {
            redirect('admin/groups');
        }
    }
    else
    {
        $this->load->view('admin/groups/update',$this->data);
    }
}
