You have 2 problem here. please have a look on comments in code.
if ($query->num_rows() > 0) {
foreach ($query->result() as $row) {
//1) $data[0]->email keep repeating same email.
// inner $query variable should be different.
$innerQuery = $this->db->select('firstname,lastname')->where('email',$row->email)->get("users");
//2) you need to store query result on array.
// $data['name_info'] stores only single record.
$data[]=$innerQuery ->result_array();
}
return $data;
}
return false;
You should avoid query in loop if you can achieve it by join
EDIT: Lets try this with join
public function fetch_result_articles($limit, $start) {
$this->db->limit($limit, $start);
$query = $this->db
->join('users u','u.email = a.email','left')
->where('a.status','1')->order_by('a.id', 'DESC')->get("articles a");
if ($query->num_rows() > 0) {
foreach ($query->result() as $row) {
$data[] = $row;
}
return $data;
}
return false;
}
I have not tested the code. but it is better way than loop.
