Laravel从2个表中获取数据，其中不为null

Question

I'm trying to get some data from two different tables,

So it does look like this now:

But I don't want the empty fields (Globale-Moderator, Moderator and Proef-Moderator) to be shown. How can I do this whit this code;

Controller:

public function ForumTeam()
    {
        $roles = Role::where('id', '>', '4')->orderBy('id', 'DESC')->get();
        return View::make('team')->with('roles', $roles);
    }

View:

<div class="panel-group col-sm-offset-1 col-sm-10">
  @foreach($roles as $role)
    <div class="panel panel-default">
      <div class="panel-heading">
        <h3 class="panel-title">{{ $role->name }}</h3>
      </div>
      <div class="panel-body">
        <ul class="list-group">

          @foreach($role->user as $user)
            <li class="list-group-item">
              <img src="{{ Config::get('app.url') }}/public/img/avatar.jpg" style="float:left;margin-right:15px;padding-bottom:5px;" class="img-circle" alt="{{ $user->username }}" width="75" height="75">
              <h4 style="color:{{ $role->colour }};"><strong>{{ $user->username }}</strong></h4>
              <p>{{ $user->usertitle }}</p>
            </li>
          @endforeach

        </ul>
      </div>
    </div>
  @endforeach
</div>

So I want to hide the not filled in fields, how should I do dis propperly?

My other option is to show some text inside of the 'empty' field. Like 'There is nobody with this rank'.

Thanks!

Answer 1

You can/should be able to use:

@foreach($roles as $role)

   @if($role->user != null || !empty($role->user->name))

   @endif

@endforeach

You can then check to see if the role->user is NOT NULL OR the name of the role is not empty.WHERE name is the name of the role, ie "Admin", "Moderator"

Alternatively, try:

  @foreach($roles as $role)

    @if(count($role->user) >= 1)
       // Do stuff
    @endif

  @endforeach

Since you are getting User which has a one-to-many relationship, therefore there will be more than one user.

Answer 2

You could add an if statement after the first @foreach , to check if the role has users,

@foreach($roles as $role)
    @if(isset($role->user))
    ...
    @endif
@endforeach
