Contoh Script PHP CRUD di Laravel 5.5

Last Updated on By 1 Comment

Untuk pembejalaran pembuat aplikasi CRUD (Create, Read, Update, Delete) di Laravel 5.5 kita akan membuat contoh database karyawan. Kita tidak akan mengunakan HTML/Form helper di Laravel.

Kebutuhan

– LAMP/LEMP yang sudah berjalan
– composer
– text editor (Sublime Text)
– koneksi internet

Buat Database

Saya menggunakan MySQL/MariaDB, login ke MySQL

mysql -u root -p

buat database baru dengan nama crudlaravel55

create database crudlaravel55;

Install Laravel

Install laravel dengan composer

composer create-project --prefer-dist laravel/laravel crudlaravel5

Edit file .env
Untuk koneksi ke database, ubah file .env

DB_DATABASE=homestead
DB_USERNAME=homestead
DB_PASSWORD=secret

contoh

DB_DATABASE=crudlaravel55
DB_USERNAME=crudlaravel55
DB_PASSWORD=crudlaravel55123

Membuat Tabel Database

Kita akan membuat satu tabel dengan nama karyawan

php artisan make:migration tabel_karyawan
## outputnya
Created Migration: 2017_11_10_033011_tabel_karyawan

Edit file di migration yang baru dibuat, letaknya ada di folder database/migrations/, di contoh nama filenya database/migrations/2017_11_10_033011_tabel_karyawan.php

Ubah menjadi

    public function up()
    {
        Schema::create('karyawan', function (Blueprint $table) {
            $table->increments('id');
            $table->string('nama_lengkap');
            $table->string('NIK');
            $table->string('Jabatan');
            $table->timestamps();
        });
    }
    public function down()
    {
        Schema::dropIfExists('karyawan');
    }

Buka file app/Providers/AppServiceProvider.php ubah function boot() menjadi

    public function boot()
    {
        \Schema::defaultStringLength(191);
    }

Sekarang jalankan php artisan migrate agar tabel tersebut dibuat di database

php artisan migrate

Routes

Buka file routes/web.php tambahkan

Route::resource('karyawan', 'KaryawanController');

Coding CRUD

Disini baru kita mulai proses kodingnya.

1. Model

Buat model untuk tabel karyawan yang tadi dibuat

php artisan make:model Karyawan

file model yang baru dibuat ada di app/Karyawan.php, ubah menjadi

class Karyawan extends Model
{
    protected $table = 'karyawan';
    protected $fillable = ['nama_lengkap', 'NIK', 'jabatan'];
}

2. Controller

Buat controller untuk Karyawan

php artisan make:controller KaryawanController

File controller tersebut berada di app/Http/Controllers/KaryawanController.php, isi lengkap file KaryawanController.php

<?php
 
namespace App\Http\Controllers;
 
use Illuminate\Http\Request;
use App\Karyawan;
 
class KaryawanController extends Controller
{
    public function index() {
        $karyawan = Karyawan::all();
        return view('karyawan.index', compact('karyawan'));
    }
 
    public function create() {
        return view('karyawan.create');
    }
 
    public function edit($id) {
        $karyawan = Karyawan::findOrFail($id);
        return view('karyawan.edit', compact('karyawan'));
    }
 
    public function store(Request $request) {
        Karyawan::create($request->all());
        \Session::flash('notifikasi', 'Karyawan berhasil ditambah.');
        return redirect('karyawan');
    }
 
    public function update(Request $request, $id) {
        $karyawan = Karyawan::findOrFail($id);
        $karyawan->update($request->all());
        \Session::flash('notifikasi', 'Karyawan berhasil diubah.');
        return redirect('karyawan');
    }
 
    public function destroy($id) {
        Karyawan::destroy($id);
        \Session::flash('notifikasi', 'Karyawan berhasil dihapus.');
        return redirect('karyawan');
    }
}

3. View

Buat file resources/views/template.blade.php yang akan digunakan sebagai master template untuk web. Isi file template.blade.php

<!doctype html>
<html lang="en">
<head>
    <title>CRUD Laravel 5.5 - jaranguda.com</title>

</head>
<body>
 
    <main role="main">
 
        <div class="container">
 
            <div class="row">
                <div class="col-md-12">
 
                @if (session('notifikasi'))
                    <div class="alert alert-success">
                        {{ session('notifikasi') }}
                    </div>
                @endif
 
                @yield('content')
 
                </div>
            </div>
        </div>
 
    </main>
 
    <script src="https://code.jquery.com/jquery-3.2.1.slim.min.js" integrity="sha384-KJ3o2DKtIkvYIK3UENzmM7KCkRr/rE9/Qpg6aAZGJwFDMVNA/GpGFF93hXpG5KkN" crossorigin="anonymous"></script>
    <script src="https://cdnjs.cloudflare.com/ajax/libs/popper.js/1.12.3/umd/popper.min.js" integrity="sha384-vFJXuSJphROIrBnz7yo7oB41mKfc8JzQZiCq4NCceLEaO4IHwicKwpJf9c9IpFgh" crossorigin="anonymous"></script>

</body>
</html>

Untuk menampilkan data dari controller karyawan, kita akan membuat satu folder karyawan dan beberapa file. Buat folder karyawan di resources/views/.

Index dan Delete

isi file index.blade.php (resources/views/karyawan/index.blade.php)

@extends('template')
 
@section('content')

Laravel Database Join Tabel Error Unknown column

Last Updated on By Leave a Comment

Ketika melakukan pencarian di datatables muncul error seperti dibawah ini

DataTables warning: table id=datatables – Exception Message:

SQLSTATE[42S22]: Column not found: 1054 Unknown column ‘db_jaranguda.client_name’ in ‘where clause’ (SQL: select count(*) as aggregate from (select ‘1’ as `row_count` from `db_jaranguda` left join `lab` on `lab_id` = `lab`.`id`

Solusi

Error tersebut muncul karena anda tidak menyertakan nama tabel di nama kolom yang diambil dari relasi antar tabel, padah contoh diatas hanya client_name harusnya clients.client_name.

Laravel Relationship method must return an object

Last Updated on By Leave a Comment

Error lengkapnya

LogicException in Model.php line 2702: Relationship method must return an object of type Illuminate\Database\Eloquent\Relations\Relation

Relationship method must return an object of type Illuminate

Solusi

Ubah save menjadi save(), contoh

$po = Po::find($request->po_id);
$po->status = 'Dikirim';
$po->save;

menjadi

$po = Po::find($request->po_id);
$po->status = 'Dikirim';
$po->save();

Membuat Pagination di Laravel 5

Last Updated on By 5 Comments

Pertama kita akan membuat database dummy (contoh), buat database baru dengan nama Tutorial, import data di bawah ini, bisa lewat phpMyAdmin atau Adminer

CREATE TABLE IF NOT EXISTS `dborang` (
  `id` mediumint(8) unsigned NOT NULL,
  `Name` varchar(255) DEFAULT NULL,
  `Country` varchar(100) DEFAULT NULL
) ENGINE=InnoDB AUTO_INCREMENT=101 DEFAULT CHARSET=latin1;
 
--
-- Dumping data for table `dborang`
--
 
INSERT INTO `dborang` (`id`, `Name`, `Country`) VALUES
(1, 'Aubrey', 'Cambodia'),
(2, 'Gloria', 'Saint Pierre and Miquelon'),
(3, 'Amery', 'Turkmenistan'),
(4, 'Robert', 'Zimbabwe'),
(5, 'Ifeoma', 'Namibia'),
(6, 'Hoyt', 'Chile'),
(7, 'Yeo', 'Brunei'),
(8, 'Erich', 'Marshall Islands'),
(9, 'Amber', 'Finland'),
(10, 'Ifeoma', 'Curaçao'),
(11, 'Sybill', 'Antigua and Barbuda'),
(12, 'Alice', 'Saint Lucia'),
(13, 'Edan', 'Bermuda'),
(14, 'Keely', 'Nicaragua'),
(15, 'Lee', 'Antigua and Barbuda'),
(16, 'Brenda', 'Tanzania'),
(17, 'Nell', 'Romania'),
(18, 'Meghan', 'Serbia'),
(19, 'Lisandra', 'Japan'),
(20, 'Aimee', 'Korea, South'),
(21, 'Cassidy', 'Egypt'),
(22, 'Reagan', 'Mayotte'),
(23, 'Medge', 'Mauritius'),
(24, 'Leo', 'Guam'),
(25, 'Aidan', 'Rwanda'),
(26, 'Eugenia', 'El Salvador'),
(27, 'Grace', 'Burkina Faso'),

(34, 'Shaeleigh', 'Oman'),
(35, 'Patrick', 'Tuvalu'),
(36, 'Avram', 'Macedonia'),
(37, 'Uma', 'Georgia'),
(38, 'Valentine', 'El Salvador'),
(39, 'Susan', 'Cape Verde'),
(40, 'Hanna', 'Malawi');
 
ALTER TABLE `dborang`
  ADD PRIMARY KEY (`id`);

Edit file app/Http/routes.php tambahkan di baris paling bawah

Route::get('orang', '[email protected]');

Buat Model (app), contoh kita beri nama Orang.php

<?php namespace App;
 
use Illuminate\Database\Eloquent\Model;
 
class Orang extends Model {
 
	protected $table = 'dborang';
	protected $primaryKeys = 'id';
 
}

Buat Controller (app/Http/Controllers), contoh kita beri nama OrangController.php

	public function index()
	{
		$orang = \App\Orang::paginate(10);
		return view('orang', compact('orang'));
	}

Buat View (resources/views), contoh kita beri nama Orang.blade.php

<!DOCTYPE html>
<html lang="">
	<head>
		<meta charset="utf-8">
		<meta http-equiv="X-UA-Compatible" content="IE=edge">
		<meta name="viewport" content="width=device-width, initial-scale=1">
		<title>Membuat Pagination di Laravel 5</title>
		<link href="//netdna.bootstrapcdn.com/bootstrap/3.2.0/css/bootstrap.min.css" rel="stylesheet">
	</head>
 
	<body>
 
<div class="container">
	<h4>Table Data</h4>
	<table class="table table-hover table-bordered">
	<thead>
		<tr>
			<th>#</th>
			<th>Name</th>
			<th>Country</th>
		</tr>
	</thead>
	<tbody>
	<?php $no = $orang->firstItem() - 1 ; ?>
	@foreach ($orang as $data)
	<?php $no++ ;?>
		<tr>
			<td>{{ $no }}</td>
			<td>{{ $data->Name}}</td>
			<td>{{ $data->Country}}</td>
		</tr>
	@endforeach
	</tbody>
</table>
<?php echo str_replace('/?', '?', $orang->render()); ?>
</div>
 
	</body>
 
</html>

Setelah semua selesai akses URL http://[IP.SERVER]/[Folder Laravel]/public/orang contoh di tempat saya http://localhost/laravel/public/orang
