Question

Hello I got the this result

A PHP Error was encountered

Severity: Error

Message: Cannot use object of type CI_DB_mysqli_result as array

Filename: controllers/Threads.php

Line Number: 48

Backtrace:

This is my codes in Controller

// category
public function threadsview($slug) {
    // get threads category
    $data['item'] = $this->threads_model->getThreadsCategory($slug);

    $data['title'] = $data['item']['catname'];
    $data['desc'] = '';

    $this->load->view('themes/default/header', $data);
    $this->load->view('threads/threadsview', $data);
    $this->load->view('themes/default/footer');
}

And the codes in my Model

 //get threads categories by slug
    public function getThreadsCategory($slug) {
        $this->db->order_by('id','asc');
        $this->db->where('slug',$slug);
        $query = $this->db->get('threads_cat');
        return $query;
    }

The error is from this code

$data['title'] = $data['item']['catname'];

I hope someone can help me regarding on this..

Thank you for your response I`ve made it and its working now

public function threadsview($slug) {
        // get threads category
        $data['item'] = $this->threads_model->getThreadsCategory($slug);
        if($data['item']->num_rows()<=0){
            $data['title'] = 'Opps!, 404 page not found';
            $this->load->view('themes/default/header', $data);
            $this->load->view('errors/html/error_404');
            $this->load->view('themes/default/footer');
        }else
        foreach ($data['item']->result() as $res) {


        $data['title'] = $res->catname;
        $data['desc'] = $res->description;

        $this->load->view('themes/default/header', $data);
        $this->load->view('threads/threadsview', $data);
        $this->load->view('themes/default/footer');
        }
    }
