undefined variable stopping if else statement from working - laravel

Question

In my app, users can create personal 'groups'. Each user has a user profile and I show the groups that they've created on their profile like this {{ ucwords(trans($groupCreated->group_title)) }} which works great.
I want their group title to be inside a green box, and to show a grey box if no groups have been created by the user.
Here's the full code for the green box:
#foreach($user->groupsCreated as $groupCreated)<div class="alert alert-success" role="alert"> {{ ucwords(trans($groupCreated->group_title)) }}</div>#endforeach
Here's what I want to show if no groups created:
<!-- <small id="emailHelp" class="form-text text-muted pb-3">Deleted groups are not shown</small>
<div class="alert alert-secondary" role="alert">
This user has no active groups</div> -->
Here's my if else statement to make this happen:
#if ($groupCreated())
<small id="emailHelp" class="form-text text-muted pb-3">Deleted groups are not shown</small>
#foreach($user->groupsCreated as $groupCreated)
<div class="alert alert-success" role="alert">
{{ ucwords(trans($groupCreated->group_title)) }}
</div>
#endforeach
#else
<!-- Show if no groups created -->
<!-- <small id="emailHelp" class="form-text text-muted pb-3">Deleted groups are not shown</small>
<div class="alert alert-secondary" role="alert">
This user has no active groups</div> -->
#endif
The error I get is Undefined variable: groupCreated
Here is my GroupController.php
<?php
namespace App\Http\Controllers;
use App\Group;
use Illuminate\Http\Request;
// All Groups pages require login except 'show'
class GroupsController extends Controller
{
public function __construct()
{

}

}

public function join(Request $request)
{
$request->validate([
'group_id' => 'required',

$user_id = auth()->id();
$group = Group::find($request->get('group_id'));
if (!$group->isLoggedInUserJoined())
$group->joinedUsers()->attach($user_id);
$redirect = $request->get('redirect', 'groups/joined');
return redirect($redirect)->with('success', 'You joined the group!!');
}
/**

*/
public function unjoin(Request $request)
{
$request->validate([
'group_id' => 'required',
]);
$group = Group::find($request->get('group_id'));
if ($group->isLoggedInUserJoined())
$group->joinedUsers()->detach(auth()->id());
$redirect = $request->get('redirect', 'groups/joined');
return redirect($redirect)->with('success', 'You\'ve left the group.');
}
/**

public function joined()
{
//#todo change query to show groups joined

$groups = auth()->user()->groupsJoined()->get();
return view('groups/joined', compact('groups'));
}
/**

}
/**

public function store(Request $request)
{
$request->validate([
'group_title' => 'required',
'group_description' => 'required',
'group_date' => 'required',
'group_time' => 'required',
]);
$group = new Group([
'group_title' => $request->get('group_title'),
'group_description' => $request->get('group_description'),
'group_date' => $request->get('group_date'),
'group_time' => $request->get('group_time'),
]);
$group->save();
return redirect('/groups')->with('success', 'Group saved!!');
}
/**

*
* #param int $id
* #return \Illuminate\Http\Response
*/
public function show($id)
{
// $group = Group::find($id);
$group = Group::with('createdByUser')->where('id', $id)->first();
return view('groups.show', compact('group'));
}
/**

*
* #param int $id
* #return \Illuminate\Http\Response
*/
public function edit($id)
{
$group = Group::find($id);
return view('groups.edit', compact('group'));
}
/**
* Update the specified resource in storage.
*
* #param \Illuminate\Http\Request $request
* #param int $id
* #return \Illuminate\Http\Response
*/
public function update(Request $request, $id)
{
$request->validate([
'group_title' => 'required',
'group_description' => 'required',
'group_date' => 'required',
'group_time' => 'required',
]);
$group = Group::find($id);
$group->group_title = $request->get('group_title');
$group->group_description = $request->get('group_description');
$group->group_date = $request->get('group_date');
$group->group_time = $request->get('group_time');
$group->save();
return redirect('/groups')->with('success', 'Group updated!');
}
/**
* Remove the specified resource from storage.
*
* #param int $id
* #return \Illuminate\Http\Response
*/
public function destroy($id)
{
$group = Group::find($id);
$group->delete();
return redirect('/groups')->with('success', 'Group deleted!');
}
}
and the Group Model
<?php
namespace App;
use Illuminate\Database\Eloquent\Model;
class Group extends Model
{
protected $fillable = [
'group_title',
'group_description',
'group_date',
'group_time',
'created_by_user_id'
];
public static function boot()
{
parent::boot();
static::creating(function ($group) {
$group->created_by_user_id = auth()->id();
});
}
/**
* Get the user that created the group.
*/
public function createdByUser()
{
return $this->belongsTo(User::class, 'created_by_user_id');
}
/**
* Get the users that joined the group.
*/
public function joinedUsers()
{
return $this->belongsToMany(User::class, 'group_joined_user', 'group_id', 'user_id')
->withTimestamps();
}
/**
* Checks whether the currently logged in user is joined to the group.
*/
public function isLoggedInUserJoined()
{
return $this->joinedUsers()->where('users.id', auth()->id())->exists();
}
}
So, I added the following to Model
/**
* Fetch the groups created by user
*/
public function groupCreated()
{
return $this->groupCreated()->where('groups.show', auth()->id());
}
But the error is:
Undefined variable: groupCreated
Any help?

Answer 1

The problem is probably #if ($groupCreated()). What is this line supposed to do?
If you just want to check if the user has any groups you can use #if ($user->groupsCreated->count() > 0).
