by Leave a Comment

There is a lot special functions that helps simplified our code like this

  1. find($id) takes an id and returns a single model. If no matching model exist, it returns null.
  2. findOrFail($id) takes an id and returns a single model. If no matching model exist, it throws an error.
  3. first() returns the first record found in the database. If no matching model exist, it returns null.
  4. firstOrFail() returns the first record found in the database. If no matching model exist, it throws an error.
  5. get() returns a collection of models matching the query.
  6. lists($column) returns a collection of just the values in the given column.
  7. toArray() converts the model/collection into a simple PHP array.

Laravel 5.3 Authentication

by Leave a Comment

Antara perkara penting dalam membangunkan applikasi adalah sistem pengurusan akses maklumat atau pun authentication & authorization.

Laravel telah memudahkan kerja kita dengan menyediakan scaffolding authentication nya tersendiri.

Anda hanya perlu install sahaja.

Tetapi untuk install sistem authentication ini ia perlu dilaksanakan pada fresh setup SAHAJA.

Execute code berikut untuk install Auth

php artisan make:auth

untuk migrate database

php artisan migrate

Dah siap!

Sekarang anda boleh ke http://domainanda/register/.

Jika anda buka file route web.php. Anda akan lihat ada panggilan method Auth::routes(). Apakah kegunaan Auth:routes() ini sebenarnya? Apa fungsi terkandung dalamnya? Apa route yang telah diistiharkan?

Ia sebenarnya adalah helper yang telah disediakan oleh Laravel.

Routes berkenaan boleh didapati disini

/vendor/laravel/framework/src/Illuminate/Routing/Router.php

Ia kelihatan sebegini

public function auth()
{
// Authentication Routes...
$this->get('login', 'Auth\LoginController@showLoginForm')->name('login');
$this->post('login', 'Auth\LoginController@login');
$this->post('logout', 'Auth\LoginController@logout')->name('logout');

// Registration Routes...
$this->get('register', 'Auth\RegisterController@showRegistrationForm');
$this->post('register', 'Auth\RegisterController@register');

// Password Reset Routes...
$this->get('password/reset', 'Auth\ForgotPasswordController@showLinkRequestForm');
$this->post('password/email', 'Auth\ForgotPasswordController@sendResetLinkEmail');
$this->get('password/reset/{token}', 'Auth\ResetPasswordController@showResetForm');
$this->post('password/reset', 'Auth\ResetPasswordController@reset');
}

Laravel 5.3 Bootstraps Installation

by Leave a Comment

Sebenarnya tiada beza nak install Bootstrap dalam Laravel dengan dalam applikasi web html yang biasa kita buat. Begitu juga Laravel versi lain.

Apa yang penting kedudukan file berkenaan hendaklah betul.

Laravel menggunakan sistem template blade yang memudahkan kita untuk menguruskan coding templating applikasi.

Dalam sistem template blade biasanya kita akan create master layout. Master layout ni umpama blueprint layout kita la. Dimana kedudukan header, footer, sidebar, menu etc.

So biasanya kita akan ubah layout seperti berikut:

<!-- Optional theme -->
<link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/css/bootstrap-theme.min.css" integrity="sha384-rHyoN1iRsVXV4nD0JutlnGaslCJuC7uwjduW9SVrLvRYooPp2bWYgmgJQIXwl/Sp" crossorigin="anonymous">

<script src="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/js/bootstrap.min.js" integrity="sha384-Tc5IQib027qvyjSMfHjOMaLkfuWVxZxUPnCJA7l2mCWNIpG9mGCD8wGNIcPD7Txa" crossorigin="anonymous"></script>

Contoh diatas menggunakan cdn Bootstrap dan jQuery.

Apa yang penting:

jQuery hendaklah dinyatakan terlebih dahulu berbanding bootstrap js. Mesti ikut susunan!

Contoh code penuh seperti berikut:

<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="utf-8">
<meta http-equiv="X-UA-Compatible" content="IE=edge">
<meta name="viewport" content="width=device-width, initial-scale=1">

<meta name="csrf-token" content="{{ csrf_token() }}">
