消息：尝试获取非对象 mvc 框架 Codeigniter 的属性

Question

I'm trying to echo/get the values in my table but I having a Message: Trying to get property of non-object

Like this one

  <tr class="project-overview-customer">
                <td class="bold"><?php echo _l('dev_oqood_status'); ?></td>
                <td><?php echo $developer->dev_oqood_status; ?></td>
            </tr>
            <tr class="project-overview-customer">
                <td class="bold"><?php echo _l('dev_contact'); ?></td>
                <td><?php echo $developer->dev_contact; ?></td>
            </tr>

on my Model i have this

public function get_developer($id = '', $where = array())
    {
       $this->db->where($where);
       if (is_numeric($id)) {
        $this->db->where('project_id', $id);
            $developer = $this->db->get('tbldevdetails')->row();
            print_r($developer); die();
        }

            return $this->db->get('tbldevdetails')->result_array();


    }

Then When I do print_r($project); die(); print_r($project); die();

stdClass Object ( [dev_id] => 20 [project_id] => 49 [dev_devloper] => [dev_purchase_date] => 2018-02-27 [dev_handover_date] => 2018-02-27 [dev_oqood_status] => Mengaw [dev_contact] => 0 [dev_email] => Mengaw [dev_landline] => Mengaw [dev_mobile] => Mengaw )

Why I have this error? Anyone can guide me?

Answer 1

$this->db->get('tbldevdetails')->row(); (which is what you are running print_r() on returns an object. Which you are correctly accessing with <?php echo $developer->dev_oqood_status; ?> . However...
You are not returning $this->db->get('tbldevdetails')->row(); you are returning $this->db->get('tbldevdetails')->result_array(); .. This is an Array which you would access like $developer[0]['dev_oqood_status']

So change your function get_developer to return $developer; instead.

Also know the difference between Result Rows And Result Arrays from the codeigniter framework

Answer 2

You are using ->result_array() to get the $developer , so $developer is not an object, but is instead an array. You should return an object instead by using ->result() .
