Codeigniter 4 query builder join display only 1 time from first table

Question

I have done up a query builder using join. I would like to show table 2, 3, 4, 5, 6 and so on based on the user id on table 1. I tried to query the result, it is showing like this :

My Tables

Table users

user_id | username | email          
1       | userA    | [email protected]
2       | userB    | [email protected]
                                                         
Table add_game
game_id | user_id | ign    | acc_id
1       | 1       | ignA   | accA
2       | 1       | ignB   | accB
1       | 2       | ignB   | accB
3       | 2       | ignD   | accD 

I will be using foreach loop and I believe it will display out multiple times based on the records in the database. What should I do if I only want to display the information highlighted in the red box (which is from users table) just 1 time and all the records associated with user id in add_game table?

This is my current code :

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[0]);
        
            echo view('templates/header', $data, $user);
            echo view('account/login', $data, $user);
            echo view('templates/footer', $data, $user);
        
        
    }


    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;
    }

Model:

return $this->db->table('users')
                        ->groupStart()
                            ->where('username', $str)
                            ->orWhere('email', $str)
                        ->groupEnd()
                        ->join('add_game', 'add_game.user_id = users.user_id')
                        ->get()
                        ->getResultArray();

I have a few more tables but not yet created for now so I have only joined 1 table for the time being. What am I missing? Or do I have to loop twice? Is there a way that I just need to loop 1 time? Hope someone can help me out here. Thanks in advance guys!

Answer 1

the easiest way to achieve this (display 2 records from add_game table and 1 record from users table) you need to create a foreach loop in your view, and exclude duplicated data from users table to be shown.

controller:

$data['my_data']=$this->Your_model->your_method(); // your query example
$this->load->view('your_view',$data)

view:

<?php $my_id=0;foreach($my_data as $row):?>
   <?php if($my_id!=$row->user_id):?>
     <div><?=$row->username?></div>   <!--data from table user-->
     <div><?=$row->created_at?></div> <!--data from table add_game-->
   <?php else:?>
     <div><?=$row->created_at?></div> <!--only data from table add_game-->
   <?php endif;?>
<?php $my_id=$row->user_id;endforeach;?>
