Body
<p>Theory:</p> <p>Users can attend many events and many events can be attended by many users. Therefore, I have two many-to-many relationships within my models, linking to a pivot table (event_user). On attending each event, I want to be able to access the pivot table data (event_user) to see if they're already attending.</p> <p>event_user: --id --event_id --user_id</p> <p>For example, my seed data is:</p> <p>user 1 attending both event 2 and 3. I want to be able to show this within a view.</p> <p>The closest I have got is (logically):</p> <pre><code>public function index() { $id = Auth::user()->id; $attending = myApp\Event::find($id)->event; var_dump($attending); **But this var_dump returns NULL, but $id returns the correct ID.** $events = myApp\Event::all(); $this->layout->content = View::make('events.index')->with('events', $events); } </code></pre> <p><strong>My aim is to disable the 'attend' button, on any event where they are already attending, only leaving the attend-able events available!</strong></p> <p><em>Any help would be hugely appreciated. Thank you in advance.</em></p> <p>Any additional code which you may find necessary:</p> <p><strong>Events Model:</strong></p> <pre><code><?php namespace myApp; use Eloquent; class Event extends Eloquent { public function consultant() { return $this->belongsToMany('myApp\Consultant'); } public function location() { return $this->belongsToMany('myApp\Location'); } public function user() { return $this->belongsToMany('myApp\User'); } } </code></pre> <p><strong>User Model:</strong></p> <pre><code><?php namespace myApp; use Eloquent; use Illuminate\Auth\UserInterface; use Illuminate\Auth\Reminders\RemindableInterface; class User extends Eloquent implements UserInterface, RemindableInterface { public function event() { return $this->belongsToMany('Event'); } public function practice() { return $this->belongToMany('Practice'); } </code></pre> <p><strong>index.blade.php (showing the event list)</strong></p> <pre><code><div class="panel panel-success">  <div class="panel-heading"><strong>Events</strong></div>   <table class="table"> <thead> <tr> <th>Title</th> <th>Date</th> <th>Presenter</th> <th>Location</th> <th></th> </tr> </thead> <tbody> @foreach($events as $event) <tr> <td>{{ $event->title }}</td> <td>{{ date("j F Y", strtotime($event->date)) }}</td> <td>{{ $event->consultant()->first()->title }} {{ $event->consultant()->first()->surname }}</td> <td>{{ $event->location()->first()->address_1 }}</td> <td><button type="button" class="btn btn-info">Attend</button></td> </tr> @endforeach </tbody> </table> </div> </table> </code></pre>

Guidance

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
