Tutorial ini merupakan kelanjutan dari tutorial Tutorial Oauth Google Dengan CodeIgniter4. kali ini kita akanmemnfaatkan view parser yang disediakan oleh framework sehingga meminimalkan terjadi serangan xss.

Menyiapkan Library

Untuk menangani tampilan, kita akan membuat sebuah library yang akan menyatukan bagian-bagian dari html untuk memudahkan penataan dan penyeragaman tampilan

  • Buat file baru di folder app/Libraries
  • Beri nama Layout.php
  • Ketikkan script berikut
<?php 
namespace App\Libraries;

use \CodeIgniter\View\Parser;

class Layout{

    public $title;

    public $data = [];

    public $view = 'home';

    
    function __construct(){
        $this->data['menus'] = null;
        $this->data['contents'] = null;
        $this->data['action'] = null;
        $this->data['fields'] = null;
    }

    public function show(){
        $parser = \Config\Services::parser(); 
        $this->data['web_title'] = sprintf('%s | Tito-OAuth',$this->title);
        $this->data['author'] = 'Harjito';
        $this->data['email'] = '[email protected]';
        $this->data['affiliation'] = 'e-project-tech.com';
        $this->data['favicon'] = 'favicon.ico';

        echo $parser->setData($this->data)->render('Partials/header');
		echo $parser->setData($this->data)->render('Partials/menu');
		echo $parser->setData($this->data)->render('Templates/'.$this->view);
		return view('Partials/footer');
    }
}

Menyiapkan View

Untuk pengaturan view, kita akan membuat dua buah folder di app/Views yaitu folder Partials dan Templates. Partials digunakan untuk memisahkan bagian header, menu dan footer. Sedangkan Templates digunakan untuk main.

  • Buat folder Partials di app/Views
  • Buat folder Templates di app/Views

Membuat HTML untuk Header

  • Buat file baru di app/Views/Partials
  • Beri nama header.php
  • Salin kode berikut
<!DOCTYPE html>
<html>
    <head>
        <meta charset="UTF-8">
        <title>{web_title}</title>
        <meta name="viewport" content="width=device-width, initial-scale=1">
        <meta name="theme-color" content="theme">
        <meta content='id' name='language'/>
        <meta content='id' name='geo.country'/>
        <meta content='Indonesia' name='geo.placename'/>
        <meta name="author" content="{author}, {email}">
        <link rel="shortcut icon" href="/e-project.ico" type="image/x-icon">

        <meta name="apple-mobile-web-app-title" content="e-Project">
        <meta name="msapplication-TileImage" content="{favicon}">
        <meta name="msapplication-TileColor" content="#2F3BA2">
        <link rel="shortcut icon" type="image/png" href="{favicon}"/>

                min-width: 90%;
            }

memodifikasi Controller

Memodifikasi Controller Home

  • Buka file app/Controllers/Home.php
  • Ganti isi method index dengan script berikut
$layout = new \App\Libraries\Layout(); 
		
$auth = Session()->auth;
		
if($auth){
			
    $layout->data['menus'] = [
        [
            'icon' => 'sign-out-alt',

return $layout->show();

Memodifikasi Controller Redirect
