how to get data from database throught model using codeigniter with for each loop -

http error occured while calling data model using function

model

    public function getproductcombo() {         $q = $this->db->get_where('products', array('type' => 'combo'));         if ($q->num_rows() > 0) {             foreach (($q->result()) $row) {                 $data[] = $row;             }             return $data;         }     } 

controller

function sets() {     $this->sma->checkpermissions();     $this->load->helper('security');      $this->data['error'] = (validation_errors() ? validation_errors() :                                                                            $this->session->flashdata('error'));      // problem in line     $this->data['showcombo'] = $this->load->sales_model->getcomboproduct();       $bc = array(array('link' => base_url(),                       'page' => lang('home')),                 array('link' => site_url('sales'),                       'page' => lang('products')),                 array('link' =>   '#', 'page' => "sets")           );     $meta = array('page_title' => "add sets", 'bc' => $bc);     $this->page_construct('sales/sets', $meta, $this->data);  } 

first of all, no need include curly braces $q->result

foreach ($q->result $row) {   $data[] = $row; } 

no need use validation_errors in php file.you can directly load form page.use validation_errors() in view page.

in controller, this

if ($this->form_validation->run() == false) {     $this->load->view('myform'); } 

then in formpage can echo

<?php echo validation_errors(); ?>
