Answer 1

Try this

In Controller

public function get_profile_check($user)
{
    echo"i in get profile check";
    $d = $this->login_m->getting_profile_check($user);

    $data=array('check_res'=>$d,'first_time'=>"no");

    foreach($d as $field)
    { 
        echo"i in for each in get";
        $image=$field->image_c;

        $view=$field->overview_c;
        $certi=$field->certi_c;
        $edu=$field->edu_c;
        $hopp=$field->hopp_c;
        $lang=$field->lang_c;
        echo"session".$image."   " .$edu;

    }
}

In Model

public function getting_profile_check($u)
{
    $this->db->select("*");
    $this->db->where('login_name', $u);
    $query = $this->db->get('profile_check');
    $result = $query->result_array();
    return $result;
}

Answer 2

do something like this in model:

public function getting_profile_check($u)
{

   $this->db->select('*')
            ->from('profile_check')
            ->where('login_name', $u);


   $query = $this->db->get();
   if($query->num_rows > 0){
       return $query->result_array();
    }

}

in controller:

public function get_profile_check($user)
{
   echo"i in get profile check";

   $d=$this->login_m->getting_profile_check($user);


    foreach ($d as $row ) {

        echo $row['name_of_table_column'];
    }


}
