Codeigniter 4 Undefined index: user_id - query-builder

Question

I am trying to show display a "join" result and only want to show the user_id, username, email only once for users table even if there are many records on the other table, so I tried to make a query builder like below:
Table users | Table add_game
|
user_id | username | email | game_id | user_id | ign | acc_id
1 | userA | userA#email.com | 1 | 1 | ignA | accA
2 | userB | userB#gmail.com | 2 | 1 | ignB | accB
| 1 | 2 | ignB | accB
| 3 | 2 | ignD | accD
Model :
<?php namespace App\Models;
use CodeIgniter\Database\ConnectionInterface;
class LoginModel{
protected $db;
public function __construct(ConnectionInterface &$db){
$this->db =& $db;
}
public function login(string $str)
{
return $this->db->table('users')
->groupStart()
->where('username', $str)
->orWhere('email', $str)
->groupEnd()
->join('add_game', 'add_game.user_id = users.user_id')
//->distinct('users.user_id')
//->select(("GROUP_CONCAT(game_id, ign, acc_id) AS userdata"))
->get()
->getResultArray();
}
}
Controller :
public function login()
{
$data = [];
helper(['form']);
$validation = \Config\Services::validation();
$db = db_connect();
$model = new LoginModel($db);
$user = $model->login($this->request->getVar('userlogin'));
$this->setUserSession($user);
echo view('templates/header', $data);
echo view('account/login', $data);
echo view('templates/footer', $data);
}
private function setUserSession($user){
$data = [
'user_id' => $user['user_id'],
'username' => $user['username'],
'email' => $user['email'],
'firstname' => $user['firstname'],
'lastname' => $user['lastname'],
'dob' => $user['dob'],
'country' => $user['country'],
'country_code' => $user['c_code'],
'contact' => $user['contact'],
'game_id' => $user['game_id'],
'ign' => $user['ign'],
'acc_id' => $user['acc_id'],
'isLoggedIn' => true
];
session()->set($data);
return true;
}
But right now I am getting
Undefined index: user_id
error message. Previously there was no issue or error when I was using without query builder for my login :
public function login(string $str, string $fields, array $data)
{
return $this->where('username', $data['userlogin'])->orWhere('email', $data['userlogin'])
->first();
}
How to resolve this error?

Answer 1

As by your comment (image) your array looks like:
Array
(
[0]=>Array
(
[user_id]=>1,
[user_name]=>'test',
//etc.
)
)
You get the
Undefined index: user_id
error message, because of addressing wrongly the array while using 'user_id' => $user['user_id']
the correct way is to add the index you want to retrieve like:
$this->setUserSession($user[0]); // where 0 can be changed to the index you pretend
now the array is flattened and 'user_id' => $user['user_id'] doesn't throw an error anymore.
