JobDetail.php // model

public function employer()
{
    return $this->belongsTo('Employer');
}

EmpCompany.php // model

public function employer()
{
    return $this->belongsTo('Employer');
} 

Employer.php // model

public function empcompanies()
{
    return $this->hasMany('EmpCompany');
}
   public function jobdetails()
{
    return $this->hasMany('JobDetail');
}

// Controller file

public function getApplyJobs($id)
{
    $jobs = JobDetail::where('id', '=', $id)->get();
    return View::make('home.apply')->with(compact('catjobs'));
}  

// view.blade.php file

@foreach($jobs as $job)
  @foreach($cat->empcompany() as $emp)
    <td {{ $emp->company_name }}</td>
  @endforeach
@endforeach
