How to Pass Multi Array(or Model) To View In Laravel

by Leave a Comment

Kadangkala kita perlu panggil beberapa model dalam satu page

First kena panggil model sebelum class controller seperti berikut

use App\Parcel;
use App\Distributor;
use App\Courier;

class ParcelsController extends Controller
{

...

Kemudian panggil seperti berikut dalam class controller. Disini kita pass lebih daripada satu variable (array).

public function create()
{
//
	$distributors = Distributor::all();
	$couriers = Courier::all();
        return view('parcels.create',compact('couriers','distributors'));
}

Contoh pada view seperti berikut

<div class="form-group">
<label for="couriers" class="col-lg-2 control-label">Couriers</label>

<div class="col-lg-10">
<select class="form-control" id="courier" name="courier">
@foreach($couriers as $courier)
<option value="{{$courier->id}}">
{{ $courier->nama }}
</option>
@endforeach
</select>
</div>
</div>

 

 

Laravel Validation Form Request On Create And Update

by Leave a Comment

Bila kita request untuk submit form, kita boleh tetapkan rules bagi validate field yang telah diisi.

Kebiasannya begini

public function rules()
{
return [
//
'nama' => 'required|min:3',
];
}

Kita juga boleh buat begini

switch($this->method())
{
case 'GET':
case 'DELETE':
{
return [];
}
case 'POST':
{
return [
//
'nama' => 'required|min:3',
'kod' => 'required|min:3',
];
}
case 'PUT':
case 'PATCH':
{
return [
//
'nama' => 'required|min:3',
'kod' => 'required|min:3',
];
}
default:break;
}

 

Laravel Migration Rename Table

by Leave a Comment

Biasa ler buat silap. Mana ada orang tak buat silap? 😛

Setiap kali buat perubahan pada table run command berikut

php artisan make:migration rename_nama_table_silap

Edit file migration dalam database/migrations/

use Illuminate\Support\Facades\Schema;
use Illuminate\Database\Schema\Blueprint;
use Illuminate\Database\Migrations\Migration;

class RenameCourierTable extends Migration
{
/**
* Run the migrations.
*
* @return void
*/
public function up()
{
//
Schema::rename('courier', 'couriers');
}

/**
* Reverse the migrations.
*
* @return void
*/
public function down()
{
//
Schema::rename('couriers', 'courier');
}
}

 

 

Submit Form Data

by Leave a Comment

Dalam Laravel kita guna GET method untuk paparkan form

Route:get ('/courer/create',CouriersController@create');

Tetapi kita gunakan POST untuk submit data. Ia tidak disimpan dalam cache dan parameter tidak disimpan dalam History, lebih secure.

Tambah pada routes.php (web.php utk versi Laravel versi 5.3 keatas)

Route:post('/courier','CouriersController@store');

Untuk memastikan data yang disimpan dalam table, kita akan lakukan validation kepada store action dengan menggnakan CourierFormRequest.

Tambah pada CouriersController.php sebelum class CouriersController

use App\Http\Requests\CourierFormRequest;
class CouriersController extends Controller
{

Tambah pada CouriersControler.php method store

public function store(CourierFormRequest $request)
{
return $request->all();
}

What is TokenMismatchException?
For security purposes, Laravel now requires a token to be sent when using the POST method. If you
don’t send any token, it will throw an error.

Tambah code berikut pada form, dibawah tag <form> utk security

<input type="hidden" name="_token" value="{!! csrf_token() !!}">

Tambah code berikut untuk paparan error jika ada field yang tidak diisi.

@foreach ($errors->all() as $error)
<p class="alert alert-danger">{{ $error }}</p>
@endforeach

Tambah code berikut untuk paparan success jika berjaya.

@if (session('status'))
<div class="alert alert-success">
{{ session('status') }}
</div>
@endif

Ringkasan:

  1. Edit Route
    • Gunakan method GET untuk paparan form (route.php)
    • Gunakan method POST untuk dapatkan data (route.php)
  2. Create Form Request
    • Gunakan FormRequest untuk validate data form (CourierFormRequest.php)
  3. Edit Controller
    • Tambah sebelum class use App\Http\Requests\TicketFormRequest;
    • Tambah method store()
  4. Edit view
    1. Tambah method post <form method=”post”>
    2. Tambah CSRF Token bawah tag <form> <input type=”hidden” name=”_token” value=”{!! csrf_token() !!}”>
    3. Tambah foreach semak error bawah tag <form> @foreach ($errors->all() as $error) <p class=”alert alert-danger”>{{ $error }}</p>
      @endforeach 
    4. Tambah foreach success jika berjaya bawah form tag @if (session(‘status’))
      <div class=”alert alert-success”>
      {{ session(‘status’) }}
      </div>
      @endif
