    $regno = $this->input->post('reg_no');
    $contact_per = $this->input->post('contact_person');
    $contact_no = $this->input->post('contact_no');
    $address = $this->input->post('address');
    $aboutCharity = $this->input->post('about_charity');
    $createdOn = date('Y-m-d H:i:s');
    if($_FILES['logo']['size'] != 0 )
    {

        $files = $_FILES;
        $config = array();
        $config['upload_path']   =   "charity_gallery/";
        $config['allowed_types'] =   "png|jpg|gif"; 
        $config['max_size']      =   "5000";
        $this->load->library('upload',$config);
        $this->upload->initialize($config);


        $this->upload->do_upload('logo');
        $imgdata = $this->upload->data();
        $image_config=array();          
        $image_config["image_library"] = "gd2";
        $image_config['overwrite'] = TRUE;
        $image_config["source_image"] = $imgdata["full_path"];
        $image_config['create_thumb'] = FALSE;
        $image_config['maintain_ratio'] = TRUE;
        $image_config['new_image'] = $imgdata["file_path"].$imgdata["file_name"];
        $image_config['quality'] = "95%";
        $image_config['width'] = 170;
        $image_config['height'] = 170;
        $this->load->library('image_lib',$image_config);
        $this->image_lib->initialize($image_config);    
        $this->image_lib->resize();
        $logo = 'charity_gallery/'.$imgdata["file_name"];




        $query = $this->db->query("INSERT INTO `charities` (charity_name, reg_no, contact_person, contact_number, address, about, logo, created_on) VALUES ('$cha_name', '$regno', '$contact_per', '$contact_no', '$address', '$aboutCharity', '$logo', '$createdOn')");
        //$cid = $this->db->insert_id();
        $aff = $this->db->affected_rows();
        return $aff;
    }else{
        $query = $this->db->query("INSERT INTO `charities` (charity_name, reg_no, contact_person, contact_number, address, about, created_on) VALUES ('$cha_name', '$regno', '$contact_per', '$contact_no', '$address', '$aboutCharity', '$createdOn')");
        //$cid = $this->db->insert_id();
        $aff = $this->db->affected_rows();
        return $aff;
    }


}

Answer 2

Try with changing the name attribute of input file to userfile. There is a note in the documentation

Note: By default the upload routine expects the file to come from a form field called userfile

Also try debug using (this will print upload errors, if any):

if ( ! $this->upload->do_upload())
{
    echo $this->upload->display_errors();
    exit();
}
