CodeIgniter Snippet

Config.php

Membuat redirect kode secara Default agar bisa menampilkan berdasarkan projek aplikasi web anda yang dibuat. Semisal anda menaruh aplikasi projek pada htdocs/namafolder/namafolder anda tidak perlu merubah base_url nya menjadi localhost/namafolder/namafolder

Dan jika URL hosting anda menggunakan https:// anda juga dapat me redirect langsung dengan cara seperti pada kode berikut:

$root=(isset($_SERVER['HTTPS']) ? "https://" : "http://").$_SERVER['HTTP_HOST'];
$root.= str_replace(basename($_SERVER['SCRIPT_NAME']), '', $_SERVER['SCRIPT_NAME']);
$config['base_url']=$root;

htaccess

<IfModule mod_rewrite.c>
RewriteEngine On
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ index.php/$1 [L]
RewriteCond %{HTTPS} off
RewriteRule .* https://%{HTTP_HOST}%{REQUEST_URI} [L,R=301]
Header set X-XSS-Protection "1; mode=block" 
</IfModule>

Template views

Themes.php

<?php
defined('BASEPATH') OR exit('No direct script access allowed');

class Themes {
	protected $_ci;
	function __construct(){
		$this->_ci=&get_instance();
	}
	function display($set, $data=null){
		$data['_content']=$this->_ci->load->view($set,$data,true);
		$this->_ci->load->view('themes.php',$data);
	}
}

/* End of file Themes.php */
/* Location: ./application/libraries/Themes.php */

Anda bisa menggunakan Library diatas untuk memudahkan load views tanpa harus membuat header, content, footer yang diulang-ulang untuk meloadnya dan anda cukup deklarasi pada Controller seperti berikut :

Home Controller

<?php
defined('BASEPATH') OR exit('No direct script access allowed');

class Home extends CI_Controller {
	
	public function __construct()
	{
		parent::__construct();
	}
	public function index()
	{
		$this->data['title']='Home';
		$this->themes->display('content/home',$this->data);
	}

}

themes.php (views)

Views - Data

Menampilkan cukup dengan seperti
<?php echo strtoupper(terbilang($jumlah)); ?>

menu_helper.php

<?php if(!defined('BASEPATH')) exit('No direct script access allowed');
if(!function_exists('active_menu')) {
  function activate_menu($controller) {

    $CI = get_instance();
    // Getting router class to active.
    $class = $CI->router->fetch_class();
    return ($class == $controller) ? 'active' : '';
  }
}

<ul>
  <li class="<?php echo active_menu('home');?>"> 
    <?php echo anchor('home','Home');?></li>
  <li class="<?php echo active_menu('about');?>"> 
    <?php echo anchor('about','About');?></li>
