my model in App\Models, I've added the company_id and year to be for the primary key

class CompanyMasterCuti extends Model
{
    use HasFactory;

    protected $table = 'company_master_cuti';
    protected $fillable = [
        'company_id', 'year', 'cuti', 'created', 'created_by', 'modified', 'modified_by', 
    ];
    protected $guarded = [];
    protected $keyType = 'string';
    public $timestamps = false;
    protected $primaryKey = ['company_id', 'year'];
    public $incrementing = false;

    public function company() {
        return $this->belongsTo('App\Models\Company', 'company_id', 'id');
    }
}

my code in controller

 public function show($company_id, $year) {

        $master_cuti = CompanyMasterCuti::where('company_id', $request->company_id)->where('year', $request->year)->first();

        return view('master-cuti.show', compact('master_cuti'));

    }

my code in index.blade.php to direct to route show

@forelse($master_cuti as $m_cuti)

  <a href="{{ route('master-cuti.show', [$m_cuti->company_id, $m_cuti->year] ) }}">
          <i class="badge-circle badge-circle-light-secondary bx bxs-show font-medium-1 text-success"></i>
  </a>
@endforelse

my code in show.blade.php

 <div class="card-content">
                                <div class="card-body">
                                    <ul class="list-group p-2" style="padding-top: 5px !important">
                                        
                                        <li class="list-group-item d-flex justify-content-between align-items-center">
                                            <span class="mr-3">Tahun</span>
                                            <span>{{ $master_cuti->year }}</span>
                                        </li>
                                        <li class="list-group-item d-flex justify-content-between align-items-center">
                                            <span class="mr-3">Cuti</span>
                                            <span>{{ $master_cuti->cuti}}</span>
                                        </li>

                                    </ul>
                                </div>
                            </div>

route

    Route::resource('master-cuti', CompanyMasterCutiController::class);

I want to display data based on company_id and year which is the primary key of the table company_master_cuti . My code is not correct because I tried to return data from the controller the data is null, what's wrong with my code? is there any solution for my problem?

Laravel does not support composite primary keys, check here. If you want to have a composite primary key you need to do all the work manually.

I would suggest having id as the primary key, and define company_id, year pair as unique key.

You can still ignore id as the primary key and use company_id, year pair as primary key, but as I mentioned that would be manual work. Check out routing and controller changes.

Route::get('master-cuti/{company_id}/{year}/show', CompanyMasterCutiController::class)->name('master-cuti.show');

 public function show($company_id, $year) {

        $master_cuti = CompanyMasterCuti::where('company_id', $company_id)->where('year', $year)->first();

        return view('master-cuti.show', compact('master_cuti'));

    }
