Assalamualaikum Sobat Semua,
Postingan kali ini akan membuat qrcode dengan mengunakkan framework Codeigniter dan library Ciqrcode
langsung saja ya sobat semua
Mungkin Cukup Itu dulu dan semoga bermanfaat. Download Full Source Code
Peralatan yang di butuhkan
- Download Framework Codeigniter versi 3 Download Disini
- Download Library Ciqrcode Download Disini
- Sudah Terinstall xampp Pengguna Windows
Implementasi Code
- extract folder framework codeigniter, kemudian rename menjadi qrcode, taruh di dalam folder xampp/htdocs
- Buat File Controller Qrcode di dalam folder controller
- Buat File Model qrcode_model didalam folder model
- Buat File Qrcode_view didalam folder view
- Buat Database misal mahasiswa
Catatan untuk folder controller, model dan view sudah di sediakan oleh framework codeigniter yang sudah sobat download
File Qrcode Controller, Copy Code dibawah
<?php
class Qrcode extends CI_Controller{
function __construct(){
parent::__construct();
$this->load->model('qrcode_model'); //pemanggilan model mahasiswa
}
function index(){
$data['data']=$this->qrcode_model->get_all_mahasiswa();
$this->load->view('qrcode_view',$data);
}
function simpan()
{
$nim = $this->input->post('nim');
$nama = $this->input->post('nama');
$prodi = $this->input->post('prodi');
$this->load->library('ciqrcode'); //pemanggilan library QR CODE
$config['cacheable'] = true; //boolean, the default is true
$config['cachedir'] = './assets/'; //string, the default is application/cache/
$config['errorlog'] = './assets/'; //string, the default is application/logs/
$config['imagedir'] = './assets/images/'; //direktori penyimpanan qr code
$config['quality'] = true; //boolean, the default is true
$config['size'] = '1024'; //interger, the default is 1024
$config['black'] = array(224,255,255); // array, default is array(255,255,255)
$config['white'] = array(70,130,180); // array, default is array(0,0,0)
$this->ciqrcode->initialize($config);
$image_name=$nim.'.png'; //buat name dari qr code sesuai dengan nim
$params['data'] = $nim; //data yang akan di jadikan QR CODE
$params['level'] = 'H'; //H=High
$params['size'] = 10;
$params['savename'] = FCPATH.$config['imagedir'].$image_name; //simpan image QR CODE ke folder assets/images/
$this->ciqrcode->generate($params); // fungsi untuk generate QR CODE
$this->qrcode_model->simpan_mahasiswa($nim,$nama,$prodi,$image_name); //simpan ke database
redirect('mahasiswa'); //redirect ke mahasiswa usai simpan data
}
}
File Qrcode_model, Copy Code dibawah
<?php
class Qrcode_model extends CI_Model{
function get_all_mahasiswa(){
$hasil=$this->db->get('mahasiswa');
return $hasil;
}
function simpan_mahasiswa($nim,$nama,$prodi,$image_name){
$data = array(
'nim' => $nim,
'nama' => $nama,
'prodi' => $prodi,
'qr_code' => $image_name
);
$this->db->insert('mahasiswa',$data);
}
}
File Qrcode_view, Copy Code dibawah

Buat Database db_qrku, buat tabel mahasiswa
Code Tabel mahasiswa
CREATE TABLE IF NOT EXISTS `mahasiswa` (
`nim` varchar(15) NOT NULL,
`nama` varchar(50) DEFAULT NULL,
`prodi` varchar(40) DEFAULT NULL,
`qr_code` varchar(50) DEFAULT NULL,
PRIMARY KEY (`nim`)
) ENGINE=InnoDB DEFAULT CHARSET=latin1;
INSERT INTO `mahasiswa` (`nim`, `nama`, `prodi`, `qr_code`) VALUES
('1210158', 'Sigit', 'Sistem Informasi', '1210158.png'),
('1210159', 'Joko', 'Manajemen Informatika', '1210159.png'),
('1210160', 'Andi', 'Sistem Komputer', '1210160.png');
Jika Sudah Buka Browser dan ketik url sesuai dengan nama folder sobat, contoh: localhost/qrcode
Kurang Lebih Hasilnya akan seperti ini
Mungkin Cukup Itu dulu dan semoga bermanfaat. Download Full Source Code
