I am getting results from a database in a controller and storing them as objects in an array
$roleSentinel = Sentinel::findRoleByName($role);
$permisssionsName = array_keys($roleSentinel['permissions']);
$permissions = array();
foreach ($permisssionsName as $permiso) {
$permissions[] = DB::table('sec_permission')->where('name', '=',$permiso)->get();
}
return view('menu', ['role' => $role,'permisos' => $permisos]);
an object would be like
[{"permission_id":1,"name":"foo","object_id":1,"operation_id":1}]
So then in the view I am trying to get the values and printing them
<b>{{$role}}</b><br>
#foreach ($permisos as $permiso)
#foreach ($permiso->name as $name)
{{$name}}
#endforeach
#endforeach
however I am getting Undefined property: Illuminate\Support\Collection::$name
Each variable in the array is an array of objects. There's two ways you can go about it.
Add another foreach:
#foreach ($permisos as $permiso)
#foreach ($permiso as $perm)
#foreach ($perm->name as $name)
{{$name}}
#endforeach
#endforeach
#endforeach
Or get one full collection with all of the names:
$permissionsName = array_keys($roleSentinel['permissions']);
$permissions = DB::table('sec_permission')->whereIn('name',$permissionsName)->get();

I have a collection which I have extracted from the database using the findMany method in eloquent.
When I dd the collection it looks like the attached image. And then I am trying to (in my blade) loop through each item in the array such that I am able to print each of the values in the actual records.
$question = Question::whereIn('id', [23,25])->get();
Then in my blade I am trying to do:
#foreach ($question as $row => $innerArray)
#foreach ($innerArray as $innerRow => $value)
{{$value->question}} //I was expecting "What is your favourite food" here
#foreach ($value->option as $choice)
<li>{{$choice}}</li> //I was expecting the list of the options here
#endforeach
#endforeach
#endforeach
What am I doing wrong?
All multi-result sets returned by Eloquent are instances of the Illuminate\Database\Eloquent\Collection object, including results retrieved via the get method or accessed via a relationship. The Eloquent collection object extends the Laravel base collection, so it naturally inherits dozens of methods used to fluently work with the underlying array of Eloquent models.
All collections also serve as iterators, allowing you to loop over them as if they were simple PHP arrays:
$questions = Question::whereIn('id', [23, 25, ..])->get();
foreach ($questions as $question) {
echo $question->title; // What is your favourite food
echo $question->name; // food
foreach ($question->options as $option) {
echo $option; // Pizza
}
}
The correct syntax is this:
#foreach ($question as $q)
{{ $q->question }} //I was expecting "What is your favourite food" here
#foreach ($q->options as $choice)
<li>{{$choice}}</li> //I was expecting the list of the options here
#endforeach
#endforeach
Instead of creating a foreach loop I want to iterate over the results and
I am using the each() method:
$collection = Comment::all();
$comment = $collection->each(function ($comment){
dd($comment->comment);
});
when I dd() I get:
"Hatter; 'so I should think."
But when I pass to view:
return view('welcome')->with('comment',$comment);
I get
[{"id":1,"post_id":5,"comment":"Hatter; 'so I should think.","created_at":"2018-04-05 15:23:20","updated_at":"2018-04-05 15:23:20"},
{"id":2,"post_id":5,"comment":"Alice gently remarked;.","created_at":"2018-04-05 15:23:20","updated_at":"2018-04-05 15:23:20"},
and so on..
This is the view:
{{$comment}}
I want to iterate through the collection and put data into $comment and then show it in the view.
It is quite simple like this.
Iterate then -> following the property name
#foreach($comment as $row)
<li>{{ $row->id }}</li>
<li>{{ $row->post_id}}</li>
//AND SO ON
#endforeach
I've an error like Trying to get property of non-object, I use var_dump and realize that I've array not object but idk how to access
public function ptkp($id){
$halaman="tindaklayanan";
$keluhan = keluhan::findOrFail($id);
$tindak = DB::table('tindakans')
->join('keluhans','keluhans.id','=','tindakans.id_keluhan')
->select(DB::raw('tindakans.id, id_keluhan, perbaikan_sementara, revisi_dokumen, target_verifikasi, ttd_tanggung1,
ttd_tanggung2'))->get();
$analisa = DB::table('analisas')
->join('tindakans','tindakans.id','=','analisas.id_tindakan')
->join('keluhans','keluhans.id','=','tindakans.id_keluhan')
->select(DB::raw('id_tindakan, analisa, tindakan, pic, tanggal_pelaksanaan'))->get();
return view('Laporan.ptkp',compact('keluhan','tindak','analisa','halaman'));
//$pdf = \PDF::loadView('laporan.ptkp', compact('keluhan','tindak','analisa','halaman'));
//return $pdf->stream();
}
Look at $tindak when I use var_dump the result is array, in View I try to access using <?php echo $tindak->perbaikan_sementara ?> but error.
Since you are in Laravel, I assume you use a blade templating engine, so you can try this in the view to access property of object :
{{ $tindak->perbaikan_sementara }}
Or if it's an array of objects :
#foreach ($tindak as $example)
{{ $example->perbaikan_sementara }}
#endforeach
if you really have an array it's in your Laporan.ptkp (better use laporan.blade.php instead)
#foreach ($tindak as $item)
{{ $item['perbaikan_sementara'] }}
#endforeach

When I use the following foreach I show the information
#foreach ($subastas as $subasta)
{{$subasta}}
#endforeach
Now I try to use the following code
#foreach ($subastas as $subasta)
#foreach ($subasta->subastas as $sub)
{{$sub}}
#endforeach
#endforeach
And I recieve this error
Trying to get property of non-object (View: C:\xampp3\htdocs\laravel\resources\views\prodcercanos.blade.php)
Any solution for this problem ?
The question is , how I can render the json in laravel ?
The controller to recieve the JSON
public function productoscercanos ($lat,$long){
$subastas = Subasta::all();
$categorias = Categoria::all();
$provincias = Provincia::all();
$cercanos = User::with(array('municipio', 'subastas'))->get();
$coordA = Geotools::coordinate([$lat,$long]);
$output = [];
foreach ($cercanos as $p) {
if(count($p->subastas)>0){
$coordB = Geotools::coordinate([$p->municipio->latitud,$p->municipio->longitud]);
$distance = Geotools::distance()->setFrom($coordA)->setTo($coordB);
$dis = $distance->in('km')->haversine();
$output[$dis] = $p."<p>$dis</p>";
}
}
ksort($output);
return view('prodcercanos')->with('categorias',$categorias)->with('provincias',$provincias)->with('subastas',$output);
}
$json = (your json file);
$subasta = json_decode($json);
then you should be able to use the json as a object now.
Try array syntax in the second foreach loop.
#foreach ($subasta['subastas'] as $sub)
{{$sub}}
#endforeach
Your code is outputting exactly what is defined. First look at how the controller is building the array.
$output[$dis] = $p."<p>$dis</p>";
$p is a User model from the variable $cercanos, appending it to $dis results in it being converted into JSON and added to your output array which your view iterates and outputs.
It looks like you are trying to add the distance to the user and pass it on.
Instead use an Accessor & Mutator to add an extra attribute to your model then pass on the $cercanos list to the view, from there you can render using a for each and grab the value.
#foreach($cercanos as $c)
{{ $c->username }} {{ $c->dis }}
#endforeach
Update
Once you have added your accessor and mutator you will be able to sort using Collections built in method.
$cercanos->sortBy('dis');
I'm trying to get the total comments the user have..
Controller:
public function index()
{
$setting = Setting::findOrFail(1);
$comments = Comment::where('published', '=', '1')->get();
$users = User::all();
return view('page.index', compact('setting', 'comments', 'users'));
}
View:
#foreach($comments as $comment)
{{ count($users->where('user_id', '=', $comment->user_id)) }}
#endforeach
The problem is that it only returns 0 and i have 2 comments there.. even using the user id to instead of "$comment->user_id" it doesnt work. still display 0.
$users is a collection, not a query. Treat it as such:
#foreach ($comments as $comment)
{{ $users->where('user_id', $comment->user_id)->count() }}
#endforeach
The collection's where method does not take an operator.
From the wording in your question it seems you actually want it the other way around:
$comments = Comment::wherePublished(1)->get()->groupBy('user_id');
Then in your view:
#foreach ($users as $user)
{{ $comments->has($user->id) ? count($comments[$user->id]) : 0 }}
#endforeach
I'm late to answer your question and Joseph already showed you the problem but you may also do it differently. You can group comments using Collection::groupBy, for example:
$comments = Comment::all()->groupBy('user_id');
Then in your view you may try this:
#foreach($comments as $user => $userComments)
// count($userComments)
// Or
#foreach($userComments as $comment)
// {{ $comment->title }}
#endforeach
#endforeach
In the first loop (#foreach($comments as $user => $userComments)), the $user is the user_id and it's value would be all comments (an array) by this user but in group.
