kali ini ane mo share ,gimana cara upload gambar , merubah ukuran dan menandakan gambar, pertama yang harus dilakukan adalah
1. download dulu Codeigniter trebaru, (ane pake versi 2.0.3)
kite g usah buat lagi yang namanye library buat upload karena di Codeigniter sudah di sediakan di system->libraries.
ada 2 file yang di butuhkan 1.image_lib.php dan upload.php. nah kite
copy file Image_lib.php ke application->libraries dan kite rename
menjadi MY_Image_lib.php dan kite edit pada bari ke 27 :
baca lebih lanjut dah..
class CI_Image_lib
jadi ,
class MY_Image_lib extends CI_Image_lib
setelah itu kite bua file di application->controller dengan file upload.php dengan code dibawah ini
buat file di controller dengan nama upload.php dengan code :
<?php
class Upload extends CI_Controller {
function __construct() {
parent::__construct();
$this->load->helper(array('form', 'url'));
}
function index() {
$this->load->view('upload_form', array('error' => ' ' ));
}
function cobaupload(){
// buat folder userfile sejajar dengan folder application dan system
$config['upload_path'] = './userfile/'; //pastikan permissionnya udah diset ke 777
$config['allowed_types'] = 'gif|jpg|png|jpeg'; //tipe file yang diperbolehkan
$config['max_width'] = 1028; //ukuran maksimal yang diperbolehkan
$config['max_height'] = 780; //ukuran maksimal yang diperbolehkan
$this->load->library('upload', $config);
if($this->upload->do_upload('myfile')){//jika file berhasil diupload
$tp=$this->upload->data();
$res = $tp['full_path'];
$ori = $tp['file_name'];
$rw = $tp['raw_name'];
$fr = $tp['file_ext'];
$kcl = $tp['raw_name'].'_thumb'.$tp['file_ext'];
$tnd = $tp['raw_name'].'_water'.$tp['file_ext'];
$mr = $tp['file_path'].$ori;
$tn = $tp['file_path'].$tnd;
$ubah = $this->ubah_ukuran_gambar($res);
$mark = $this->watermarking($mr);
chmod($res,0777);
chmod($tn,0777);
$data = array('upload_data' => $this->upload->data(),'ori'=>$ori,'tnd'=>$tnd,'kcl'=>$kcl);
$this->load->view('upload_success', $data);
}
else {//jika gagal
$error = array('error' => $this->upload->display_errors());
$this->load->view('upload_form', $error);
}
}
// function buat bikin tanda di gambar
function watermark($gb) {
$config['source_image'] = $gb;
$config['wm_text'] = 'D U T A L A'; // tanda yang akan tercetak di gambar
$config['wm_type'] = 'text';
$config['wm_font_path'] = './system/fonts/BOWSHADW.TTF'; //pastikan fontnya ada
$config['wm_font_size'] = 60;
$config['wm_font_color'] = '00000';
$config['wm_vrt_alignment'] = 'middle';
$config['wm_hor_alignment'] = 'center';
$config['wm_padding'] = 5;
$config['thumb_marker'] = '_water';
$config['wm_opacity'] = 5;
$config['wm_shadow_color'] = 333333;
$this->image_lib->initialize($config);
$this->image_lib->watermark();
}
function watermarking($gb) {
$config['source_image'] = $gb;
$config['wm_type'] = 'overlay';
$config['wm_overlay_path'] = './userfile/lara.png';
//ganti gambar sesuai yg bro pnya ini untuk watermarking
$config['wm_font_color'] = '00000';
$config['wm_vrt_alignment'] = 'middle';
$config['wm_hor_alignment'] = 'center';
$config['wm_padding'] = 5;
$config['wm_x_transp'] = 0;
$config['wm_y_transp'] = 5;
$config['thumb_marker'] = '_water';
$config['wm_opacity'] = 75;
$this->image_lib->initialize($config);
$this->image_lib->watermark();
}
// function merubah ukuran gambar
function ubah_ukuran_gambar($tp) {
$config ['image_library'] = 'gd2';
$config ['source_image'] = $tp;
$config ['create_thumb'] = TRUE;
$config ['maintain_ratio'] = TRUE;
// ukuran akan di ubah tidak kedua-duanya bisa jadi width atau height saja
$config ['width'] = 300;
$config ['height'] = 250;
$this->load->library('image_lib',$config);
$this->image_lib->resize();
}
}
setelah itu kita buat file upload_form.php di application->view dengan code dibawah ini :
<html>
<head>
<title>Upload Form</title>
</head>
<body>
<?php echo $error;?>
<?php
//jangan lupa menyertakan $this->load->helper('form'); di controller yang memanggil view ini
echo form_open_multipart('upload/cobaupload', '');?>
<div style="padding-left:35px;">
<h2>upload, resize & watermarking</h2>
<?php
echo form_upload('myfile').
form_submit('submit', 'Submit').'</p>';
?>
</form>
</div>
</body>
</html>
dan buat satu lagi dengan nama upload_success.php dengan code :
<html>
<head>
<title>Upload Form</title>
</head>
<body>
<div style="padding-left:5px;">
<h3>Your file was successfully uploaded!</h3>
<ul>
<?php foreach ($upload_data as $item => $value):?>
<li><?php echo $item;?>: <?php echo $value;?></li>
<?php endforeach; ?>
</ul>
<p><?php echo anchor('upload', 'Upload Another File!'); ?></p>
</div>
<h1>File Asli</h1>
<img src="<?=base_url();?>userfile/<?=$ori;?>"><br/><?php echo $ori;?></img></div>
<h1>File yang sudah di watermarking</h1>
<img src="<?=base_url();?>userfile/<?=$tnd;?>"><br/><?php echo $tnd;?></img>
<div style="margin:-730px 0 0 1100px;">
<h1>File yang sudah di resize</h1>
<img src="<?=base_urll();?>userfile/<?=$kcl;?>"><br/><?php echo $kcl;?></img>
</div>
</body>
</html>
