Hashids module for codeigniter HMVC

Hashids is a small open-source library that generates short, unique, non-sequential ids from numbers. It converts numbers like 347 into strings like “yr8”, or array of numbers like [27, 986] into “3kTMd”. You can also decode those ids back.

modules

  |_Hashids
 	  |_config
 	      |_encrypt.php // $config['salt']='setEncryptionDecryptionString';
 	  |
      |_controller
          |_Hashids.php

third_party

|_hashids
    |_lib
    |_Vendore
    |_composer.json

Third party folder contain all dependancies which required for hashids

Hashids Controller :

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

require_once APPPATH."/third_party/hashids/vendor/autoload.php"; 

class Hashids extends Controller 
{

	private $hashids='';
	function __construct(){
	
	    parent::__construct();
   	    $this->config->load('hashids/encrypt', TRUE);
      	    $config_encrypt=$this->config->item('encrypt');
      	    $this->hashids = new Hashids\Hashids($config_encrypt['salt']);
	    
	}
 	public function encrypt($plainText)
 	{
	 	return $this->hashids->encode($plainText);
 	}
 	public function decrypt($cipherText,$single_flag=TRUE)
 	{
 		if($single_flag == TRUE)
 		{
 			$single_decrypt = $this->hashids->decode($cipherText);
 			return $single_decrypt[0];
 		}
 		else
 		{
 			return $this->hashids->decode($cipherText);;
 		}
 	}

}

Example :-

class Site extends Controller
{

	function __construct()
	{
		parent::Controller();
		$this->load->module('hashids'); // load module
	}
	
	function members_area()
	{
		modules::run('login/is_logged_in');
		$user_id=2;
		$data['id']=$user_id; // Normal Id 
		$encrypt_id = $this->hashids->encrypt($user_id); 
		// encrypt() function from hashid module will convert normal id into encrypted Id
		
		$data['encrypt_id']=$encrypt_id; // encrypted Id
		
		$decrypt_id = $this->hashids->decrypt($encrypt_id); 
		// decrypt() function will convert encrypted id back to normal id 
		
		$data['decrypt_id']=$decrypt_id; // Normal Id
		$this->load->view('logged_in_area',$data);
	}
}

Note :- Controller is name of Base controller
