How to link two tables with a pivot table? - php

Question

Hey so a bit of an overview of the project i want to do. I want to show the user's teams.
When the user logged in and opened the viewteams page. He must show teams he joined/created. To do so i ve done the below processes...
my ViewTeamController
{
public function index()
{
$user=User::first();
$teams=Team::all();
$user->teams()->attach($teams);
return view('teams.viewteams',compact('teams'));
}
public function store()
{
}
}
my User model
public function teams(){
return $this->belongsToMany(Team::class,'team_user','teams_id','users_id');
}
my Team model
public function users(){
return $this->belongsToMany(User::class,'team_user','teams_id','users_id');
}
my migration of the pivot table
public function up()
{
Schema::create('team_user', function (Blueprint $table) {
$table->unsignedBigInteger('users_id');
$table->unsignedBigInteger('teams_id');
$table->index('users_id');
$table->index('teams_id');
$table->timestamps();
});
}
web.php routes
Route::get('/viewteams','ViewTeamController#index');
Route::post('/viewteams','ViewTeamController#store');
my viewteams.blade.php
#extends('layouts.app')
#section('content')
<div class="container">
<div class="row justify-content-center">
<div class="col-md-8">
<div class="card">
<div class="card-header"><h2 style="text-align:center;">Your Teams</h2></div>
<div class="card-body">
#foreach ($teams as $team)
#foreach($team->users as $user)
{{$user->org_name}}
#endforeach
#endforeach
</div>
</div>
</div>
</div>
</div>
#endsection
my other controller for Creating a team
<?php
namespace App\Http\Controllers;
use App\Team;
use Illuminate\Http\Request;
class CreateTeamController extends Controller
{
public function index(Request $request)
{
return view('teams.createteams');
}
public function store(Request $request)
{
$team=Team::create($request->all());
return redirect()->route('home');
}
}
all my routes
Route::get('/login', function () {
return view('auth/login');
});
Auth::routes();
Route::get('/viewteams','ViewTeamController#index');
Route::post('/viewteams','ViewTeamController#store');
Route::get('/createteams','CreateTeamController#index');
Route::post('/createteams','CreateTeamController#store') ;
Route::get('/home', 'HomeController#index')->name('home');

Answer 1

To achieve currents users teams, first you should get authenticated user id using Auth facade.
After that you can load joined teams for user, using 'with' method. It loads teams relationships.
ViewTeamController
public function index()
{
$user = User::with('teams')->find(Auth::id());
return view('teams.viewteams',compact('user'))
}
viewteams.blade.php
#section('content')
<div class="container">
<div class="row justify-content-center">
<div class="col-md-8">
<div class="card">
<div class="card-header"><h2 style="text-align:center;">Your Teams</h2></div>
<div class="card-body">
#foreach ($user->teams as $team)
{{ $team->name }}
#endforeach
</div>
</div>
</div>
</div>
</div>
#endsection

You will need to revisit and update the code which stores data to the users table and the teams user. The easiest way to store the data in a way which populates the pivot table is to use the sync() method as described at https://laravel.com/docs/master/eloquent-relationships#updating-many-to-many-relationships
I'm making some assumptions about names and relationships, buy you may have something like this:
$user = User::find(2);
$user->teams()->sync([4,5]);
In this case, you would put into the pivot table a record for user_id of 2 and team_id of 4, and a second record for a user_id of 2 and a team_id of 5.
If you want to share more code showing route definitions and controllers for how you are currently handling things, we can help with any more specific implementation questions.
