Laravel get data from 2 tables where not null - php

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($role->user->name))
#endif
#endforeach
You can then check to see if the role->user is NOT NULL OR the name of the role is not empty.WHERE name is the name of the role, i.e. "Admin", "Moderator"
Alternatively, try:
#foreach($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
