I do have an app in Laravel 5.5 using Laratrust last version to give roles and permissions.
Now, I want to let and Administrator lists only the users he has created and let the Superadministrator see ALL users.
Let's see some code:
UserController.php
public function index()
{
$id = Auth::user()->id;
if ($id = Laratrust::hasRole('superadministrator')) {
$users = User::orderBy('id', 'desc')->paginate(10);
}
$users = User::where('id', '=', $id)->orderBy('id', 'desc')->paginate(10);
return view('manage.users.index')->withUsers($users);
}
Manage navbar:
#if(Laratrust::hasRole('superadministrator|administrator'))
<li>Usuários</li>
<li>
<a class="has-submenu {{Nav::hasSegment(['roles', 'permissions'], 2)}}">Cargos & Permissões</a>
<ul class="submenu">
<li>Cargos</li>
<li>Permissões</li>
</ul>
</li>
#endif
Any ideas, please?
You are overwriting the $users variable in controller

I have a system that requires a homeowner to submit a form about their guest's details. When they submit a form, each will be assigned a unique 6-digit code. This code will be hashed with SHA-256. In the admin's view, there is a list of all submitted forms. I want to do a search function where when I enter the code, the system will look through the hashed code and check if it exists or not.
This is my GuestController:
public function index()
{
//returns admin's view
$guest = Guest::all();
return view('pages.guest.index', compact('guest'));
}
public function store(Request $request)
{
$guest = new Guest;
$guest->code = random_int(100000, 999999);
$guest->hash = hash('sha256', $guest['code']);
$guest->owner_id = Auth::user()->id;
$guest->owner = Auth::user()->name;
$guest->unit = Auth::user()->unit;
$guest->guestname = $request->input('guestname');
$guest->guestphone = $request->input('guestphone');
$guest->guestic = $request->input('guestic');
$guest->guestcar = $request->input('guestcar');
$guest->numberofguests = $request->input('numberofguests');
$guest->datevisit = $request->input('datevisit');
$guest->timevisit = $request->input('timevisit');
$guest->save();
return redirect('show-pass')->with('status', 'Guest Added Successfully');
}
public function search(Request $request)
{
//Get the search value from the request
$search = $request->input('search');
//Search in the code from the list
$guest = Guest::query()
->where('code', 'LIKE', "%{$search}%")
->get();
//Return the search view with the results compacted
return view('pages.guest.search', compact('guest'));
}
This is my search result blade:
<div class="card-body">
#if($guest->isNotEmpty())
#foreach ($guest as $item)
<div class="post-list">
<p>Owner : {{ $item->owner }}</p>
<p>Unit : {{ $item->unit }}</p>
<p>Guest Name : {{ $item->guestname }}</p>
<p>Guest Phone Number : {{ $item->guestphone }}</p>
<p>Guest IC Number : {{ $item->guestic }}</p>
<p>Guest Car Number : {{ $item->guestcar }}</p>
<p>Date : {{ $item->datevisit }}</p>
<p>Time : {{ $item->timevisit }}</p>
</div>
#endforeach
#else
<div>
<h4>No guests with the code was found</h4>
</div>
#endif
</div>
Is what I'm trying to do possible? If yes, how can I edit my search method to be able to do so? May I get some help?
I am trying to pass 2 variables to View Composers like this:
public function compose(View $view)
{
$catalog = Category::with('children')->where('parent_id', NULL)->get();
//
if(isset($catalog->img)){
// $cat = Category::
$contents = collect(Storage::disk('google')->listContents('sdfJSALSNldKdnslwk230jsd/', false));
$file = $contents
->where('type', '=', 'file')
->where('filename', '=', pathinfo($catalog->img, PATHINFO_FILENAME))
->where('extension', '=', pathinfo($catalog->img, PATHINFO_EXTENSION))
->first();
$catimg = isset($file['path'])?(Storage::disk('google')->exists($file['path'])?Storage::disk('google')->url($file['path']):NULL):NULL;
};
//
return $view->with(['catalog' => $catalog, 'catimg' => $catimg]);
}
But I am getting the error: Undefined variable $catimg.
Perhaps this is not the correct method for passing the second variable?
And also, at the top I check if the image exists in the database, but it seems to me that this is the wrong way, since only parent elements are returned there, how can I check if there is an image for each category? Probably need to run through foreach?
#foreach( $catalog as $item )
<li class='has-sub'><img class="catalogimg" src="#isset($item->img){{Storage::url($catimg)}}#else /img/categories/kitchen-utensils.png #endisset"><span class="cat-text">{{ $item->name }}</span>
<ul>
#foreach( $item->children as $subitem )
<li><span class="cat-text">{{ $subitem->name }}</span></li>
#endforeach
</ul>
</li>
#endforeach
You are passing the variables correctly!
The problem is that you defined $catimg only inside your if-structure.
You will have to think about the case when isset($catalog->img) is false.
In this case no image is present for the category and the if-structure won't be entered and therefore $catimg is not defined. So you will either have to check in your view file if $cat_img is set, return a default image or disallow this action. (Or only allow categories with images).
Everything works perfectly okay on localhost but when migrated to godaddy live server(cpanel) I keep getting this error (Undefined offset: 0) on my blade view
I have tested the application on my localhost using XAMPP running PHP 7.2.12 and it works very fine but now I moved it to godaddy cpanel running PHP 7.3 and it keeps giving me this error

At the Controller, this code is expected to retrieve all the messages from the database linking to the logged in user either send or received, store them using an array and display them at the blade template looping through each of the array.
Currently that is what it does on localhost but on live server I get this error message Undefined offset: 0 (View: /resources/views/conversations.blade.php)
You are overwriting the variable in your foreach loop, therefore on the second iteration, it's looping in the profile object instead of your original array.
Change your controller to:
'profiles' => $profiles,
And change your foreach to loop through $profiles instead:
#foreach ($profiles as $profile)
And replace your $profile[0] with $profile.
I have found the solution to this issue, I was using === instead of == where I have this code
if($userRole[0]->role_id === 2)
I now change this line of code to
if($userRole[0]->role_id == 2)
and now is working perfectly well.
Thank you for your response Chin Leung.
I want to create slug by using value of $item->name = $request->input('name'); before $item->save();
//use Illuminate\Support\Str;
private function saveItem(Request $request, $item){
$item->name = $request->input('name');
$item->slug = Str::title($item->name,"-");
$item->save();
}
When the $item->name = $request->input('name') value is Hello World,
Then after slug the output will be Hello-World
Please help.
You can generate a slug using the Str::slug() method:
private function saveItem(Request $request, $item){
$item->name = $request->input('name');
$item->slug = Str::slug($item->name);
$item->save();
}
I have table called 'players'. I want to pull every player from the database, or simply select players that have in column 'online' = 1. I want to display their name (column 'name') in 'players' table.
Here's what I've tried:
public function online()
{
$results = Player::with('online')->find(1)
return View::make('aac.test')->with('results', $results);
}
also tried:
public function online()
{
$results = DB::select('select * from players where level = 1');
return View::make('aac.test')->with('results', $results);
}
None of them works.
Try this:
public function online()
{
$results = Player::where('online', 1)->get('name');
return View::make('aac.test')->with('results', $results);
}
To display it using blade:
<ul>
#foreach($results as $result)
<li>
{{$result->name}}
</li>
#endforeach
</ul>
public function online()
{
$results = Player::where('level','=','1')->get();
return View::make('aac.test')->with('results', $results);
}
To display it using blade:
<ul>
#foreach($results as $result)
<li>
{{$result->name}}
</li>
#endforeach
</ul>
