Question

如果我的数据库表中没有记录，我收到错误提供的无效参数foreach（）可以帮我解决这个错误。

控制器代码

$data['cc'] = $this->Profile_model->supplier_companydetails();
$this->load->view('suppliercompany', $data);

型号代码

public function supplier_companydetails() {

        $this->db->select('*');
        $this->db->from('supplier_otherdetails');
        $this->db->where('supplierid_fk', $this->session->id);
        $query = $this->db->get();
        //return $query->result();

           if ($query->num_rows() > 0) {
            foreach ($query->result() as $row) {
                //add all data to session
                $newdataaa = array(

                     'company_name' => $row->company_name,
                     'company_estd_date' => $row->company_estd_date,
                     'tin_number' => $row->tin_number,
                     'company_address' => $row->company_address,
                     'area' => $row->area,
                     'city' => $row->city,
                     'state' => $row->state,
                     'country' => $row->country,

                );
            }
            $this->session->set_userdata($newdataaa);
            return $query->result();
        }

    }

只需修改此行

即可

foreach ($query->result() as $row) {

致

foreach（（array）$ query-＆gt; result（）as $ row）{

为foreach（）提供的参数无效
