[CodeIgniter] Upload dan Resize Gambar Secara Otomatis
Saya sering mondar-mandir membaca pertanyaan-pertanyaan member di group CodeIgniter Indonesia dan tak jarang ada yang bertanya atau mempertanyakan bagaimana cara mengupload gambar dan meresize gamber tersebut secara otomatis. Nah, maka dari itu kali ini saya akan memberikan sedikit bahkan secuil contoh penggunaannya.
Buat project baru dengan codeigniter, kemudian buka controller welcome.php, kemudian isi seperti berikut.
Berikut penampakannya.
Buat project baru dengan codeigniter, kemudian buka controller welcome.php, kemudian isi seperti berikut.
<?php if ( ! defined('BASEPATH')) exit('No direct script access allowed');
class Welcome extends CI_Controller {
public function __construct()
{
parent::__construct();
$this->load->helper(array('form', 'url', 'html'));
$this->load->library(array('upload','image_lib'));
}
public function index()
{
$data = array();
$data['error'] = '';
$data['output'] = '';
if(isset($_FILES['userfile']))
{
$this->upload->initialize(array(
'upload_path' => './assets/',
'allowed_types' => 'png|jpg|gif',
'max_size' => '5000',
'max_width' => '3000',
'max_height' => '3000'
));
if($this->upload->do_upload())
{
$data_upload = $this->upload->data();
$this->image_lib->initialize(array(
'image_library' => 'gd2',
'source_image' => './assets/'. $data_upload['file_name'],
'maintain_ratio' => false,
'create_thumb' => true,
'quality' => '20%',
'width' => 240,
'height' => 172
));
if($this->image_lib->resize())
{
$output = '<h4>Thumb - hasil Resize</h4>';
$output .= img('./assets/'.$data_upload['raw_name'].'_thumb'.$data_upload['file_ext']);
$output .= '<h4 style="margin-top: 30px">Gambar Original</h4>';
$output .= img('./assets/'.$data_upload['file_name']);
$data['output'] = $output;
}
else
{
$data['error'] = $this->image_lib->display_errors();
}
}
else
{
$data['error'] = $this->upload->display_errors();
}
}
$this->load->view('welcome_message', $data);
}
}
/* End of file welcome.php */
/* Location: ./application/controllers/welcome.php */
Kemudian buka folder views/welcome_message.php dan isi seperti berikut.<!DOCTYPE html>
