I have a database with 3 tables. A separate model is connected to each table, and there is a controller that accepts values from all models. On the site page, I will have 3 tables that will be populated from a mysql table.
When I connected 2 models, everything worked fine. But after connecting 3, I get an error
undefined variable: sec_3.
If you delete one of the variables, then everything will work fine. It seems to me that the problem is either with the controller or with the file blade.php but I do not know how to fix it so that everything works properly. How to fix it?
My code:
Controller:
class PreschoolInstitution3Controller extends Controller {
public function index(){
$context=['bbs' =>PreschoolInstitution3::latest()->get()];
$context_2=['s' =>PreschoolInstitution::latest()->get()];
$context_3=['sec_3' => TrainingPrograms::latest()->get()];
return view('our_employees', $context, $context_2, $context_3);
}
}
web.php:
Route::get('/OurEmployees',[PreschoolInstitution3Controller::class,'index'] )->name('OurEmployees');
blade.php:
#foreach ($s as $section_2) <tr> <td>{{$section_2->number}}<td> <td>{{$section_2->fullname }}<td> <td>{{$section_2->post }}<td> <td>{{$section_2->telephone }}</td> <td>{{$section_2->email }}</td>
#endforeach #foreach ($bbs as $section )
{{$section->number}} {{$section->full_name}} {{$section->post}} {{$section->education}} {{$section->category}} {{$section->teaching_experience}} {{$section->professional_development}}
#endforeach #foreach ($sec_3 as $section_3)
{{ $section_3->number }}
{{ $section_3->level }}
{{ $section_3->directions }}
{{ $section_3->type_of_educational_program }}
{{ $section_3->period_of_assimilation }}
{{ $section_3->number_of_students }}
#endforeach
You should pass an array of data to view:
class PreschoolInstitution3Controller extends Controller {
public function index(){
$context = [
'bbs' => PreschoolInstitution3::latest()->get(),
's' => PreschoolInstitution::latest()->get(),
'sec_3' => TrainingPrograms::latest()->get()
];
return view('our_employees', $context);
}
}
https://laravel.com/docs/9.x/views#passing-data-to-views
Another one is that add a second parameter of an array with name to view( ) .
class PreschoolInstitution3Controller extends Controller {
public function index(){
$bbs = PreschoolInstitution3::latest()->get();
$s = PreschoolInstitution::latest()->get();
$sec_3 = TrainingPrograms::latest()->get();
return view('our_employees', [
'bbs' => $bbs,
's' => $s,
'sec_3' => $sec_3
]);
}
}

This code is working fine
public function render(){
$this->products = ProductModel::get();
return view('livewire.product');
}
But when I am trying to paginate using laravel livewire, it gives me an error
public function render(){
return view('livewire.product', [
'products' => ProductModel::paginate(10)
]);
}
Blade File
#foreach ($products as $product)
{{ $product->name }}
{{ $product->price }}
#endforeach
#if(!empty($products))
{{ $products->links() }}
#endif
import this in Component
use Livewire\WithPagination;
class Product extends Component
{
use WithPagination;
....
}
and add in view
#if(!empty($products))
{{ $products->links() }}
#endif
Ohh I got it.Actually I have already use $products variable as a global variable
and when I change $products to other name it works.
Thanks alot...
I want to make a PHP method using laravel. I want to do the comparison of criteria and criteria. Here is the controller code :
public function create()
{
$kriteria1 = Model\Kriteria::pluck('nama_kriteria', 'id');
$kriteria2 = Model\Kriteria::pluck('nama_kriteria', 'id');
return view('kriteria_kriterias.create')->with('kriteria1', $kriteria1)->with('kriteria2', $kriteria2)->with('data', $data);
}
and this is the blade code :
It will make the form appear as total of criteria#
The problem is, I can't save it all to database. How do I get it to do this?
Updated method in the controller to the following:
public function create()
{
$kriteria1 = Model\Kriteria::pluck('nama_kriteria', 'id');
$kriteria2 = Model\Kriteria::pluck('nama_kriteria', 'id');
$data = [
'kriteria1' => $kriteria1,
'kriteria2' => $kriteria2
];
return view('kriteria_kriterias.create')->with($data);
}
How to output in the blade file:
{{ $kriteria1 }}
{{ $kriteria2 }}
Or you update the controller to pass the complete results:
public function create($id1, $id2)
{
$kriteria1 = Model\Kriteria::find($id1);
$kriteria2 = Model\Kriteria::find($id2);
$data = [
'kriteria1' => $kriteria1,
'kriteria2' => $kriteria2
];
return view('kriteria_kriterias.create')->with($data);
}
And the in the blade you can accss the data in various ways, one way is a foreach loop using blade in the blade template:
#foreach($kriteria1 as $k1)
{{ $k1 }}
#endforeach
#foreach($kriteria2 as $k2)
{{ $k2 }}
#endforeach'
To accept multiple values dynamicaly in the controller you can try something like this:
public function create($ids)
{
$results = collect([]);
foreach($ids as $id) {
$kriteria = Model\Kriteria::findOrFail($id);
if($kriteria) {
$results->put('kriteria' . $id, $kriteria);
}
}
return view('kriteria_kriterias.create')->with($results);
}
Then use the same looping method mentioned above to display them in the blade or a for loop that gets the count and displays accordingly.
maybe you forgot to add the opening tag ;)
{!! Form::open(array('url' => 'foo/bar')) !!}
//put your code in here (line 1-34)
{!! Form::close() !!}
I've been working on a webapp recently in laravel and i wanted to have a eddit function within tthe application. but im getting this error Missing required parameters for [Route: producten.update] [URI: producten/{producten}], and i dont know what i've done wrong.
This is the Routes im using:
Route::resource('producten', 'ProductenController', ['only' => ['index', 'store', 'update', 'delete', 'edit', 'destroy', 'create']]);
This is the controller function im using for showing the edit page and updating.
The Edit function
public function edit(Request $request, Product $product)
{
// $product = Product::FindorFail($id);
// Product is a table with all products, with sellprice and buy price
// fabriek = table that has a foreign key attached to the product table
return view('producten.edit', [
'model' => $product,
'fabrieks' => Fabriek::lists('Id')
]);
}
The Update Function:
public function update(Request $request, Product $product)
{
$product->update($request->all());
return redirect(Route('producten.index'));
}
and this is the view i use for it.
{{Form::model($model, ['method' => 'PATCH', 'action' => 'ProductenController#update', $model ]) }}
{{ Form::label('naam:')}}
{{ Form::text('naam') }} <br>
{{ Form::label('inkoopPrijs:')}}
{{ Form::text('inkoopPrijs') }} <br>
{{ Form::label('verkoopPrijs:') }}
{{ Form::text('verkoopPrijs') }} <br>
{{Form::label('Fabrieken', 'Fabrieken Id:') }}
{{ Form::select('Fabrieken_Id', $fabrieks)}} <br>
{{ Form::submit('edit')}}
{{ Form::close() }}
if there is anything else that i need to add to the question just let me know and i'll add it
Missing thing is the id you are not getting id there in your edit function
your edit function should as i am assuming that you are just showing the form from this method where user can edit
public function edit($id)
{
$product = Product::FindorFail($id);
//Product is a table with all products, with sellprice and buy price
//fabriek = table that has a foreign key attached to the product table
return view('producten.edit', [
'model' => $product,
'fabrieks' => Fabriek::lists('Id')
]);
}
your update method should seem like this
public function update(Request $request, $id)
{
$product->update($request->all());
return redirect(Route('producten.index'));
}
your routes should like this no need for only
Route::resource('/producten', 'productionController');
edit route will be as
<a href="{{ route('production.edit', $model->id) }}">
Try this hope it will help
My controller is
public function index()
{
$users = User::paginate(15);
return view('dash.users.index')->with(array('users' => $users));
}
in view i pass: {{ $item->roles }} and return all column as array, if i put {{ $item->roles->get('name') }}the table is blank, why?
I want to show user->roles->name foreach user
If it's an array, you should only simply use this:
{{ $item->roles['name'] }}
solved with nested foreach! #foreach($item->roles as $item) {{ $item['name'] }} #endforeach
inside my #foreach user
Thank you Mojtaba for the help!
My Controller :
public function show($id){
$user_id_1_connections = Connection::whereUser_id_1AndConnection_status($id, 1)->get();
$user_id_2_connections = Connection::whereUser_id_2AndConnection_status($id, 1)->get();
return view('connection.showConnection',['user_id_1_connections' => $user_id_1_connections, 'user_id_2_connections' => $user_id_2_connections]);
}
My Model :
protected $table = 'connections';
protected $fillable = ['user_id_1','user_id_2','connection_status'];
public function user()
{
return $this->belongsTo('App\User');
}
My Blade :
#foreach($user_id_1_connections as $user_id_1_connection)
{{ $user_id_1_connection->user->name }}
{{ $comment->user->name }}
#endforeach
#foreach($user_id_2_connections as $user_id_2_connection)
{{ $user_id_2_connection->user->name }}
#endforeach
I have made foreign key to user_id_1 and user_id_2 to users table.
$table->integer('user_id_1')->unsigned();
$table->foreign('user_id_1')->references('id')->on('users')->onDelete('cascade');
$table->integer('user_id_2')->unsigned();
$table->foreign('user_id_2')->references('id')->on('users')->onDelete('cascade');
But when I'm running this code. It's showing the error :
Trying to get property of non-object.
The problem here is probably that you don't have user assigned to each connection so instead of:
{{ $user_id_1_connection->user->name }}
you should write rather something like this:
{{ $user_id_1_connection->user ? $user_id_1_connection->user->name : 'unknown' }}
same in all other places when you use $x->y->z syntax. To display z you should make sure $x->y is not null
