I'm doing a website where companies have persons which have scores per event. And the events are ordered by city.

So by example someone can do 4 events, so they get a score for each event.

I'm using a pivot table to save the scores. ( here's a screenshot )

enter image description here

Now i'm loading all persons for a certain event with the following query.

$data['companies'] = Event::find($id)->city->companies;

And i'm showing them using the following structure in my blade file

@foreach($companies as $company)
   {{ $company->name }}
        @foreach($company->persons as $person)
           {{ $person->firstname }}
           {{ $person->eventscore }}

The person->eventscore is the link to the pivot table. And it's working but it's giving me the scores of that person for ALL the events.

I only want to see the score for the event that we are watching now ( you can see the id in the url bar, and i marked the id with a red arrow, Now how can i? In my view ask to only show to score for the specific event?

enter image description here

Thank you!

    There need to a little change in your query.. See the below example.

    class Person extends Eloquent {
        public function events()
            return $this->belongsToMany('Event', 'person_event', 'event_id', 'person_id')->withPivot('id','score');
    class Event extends Eloquent {
        public function persons()
            return $this->belongsToMany('Person', 'person_event', 'person_id', 'event_id')->withPivot('id','score');

    Now to loading all persons for a certain event, query is ..

    $event_id = 1;
    $persons = Person::with('events')->whereHas('events', function($q) use ($event_id){$q->where('event_id',$event_id);})->get();

    In view...

    @foreach($persons->events as $event)
        {{ $event->pivot->score}}
