CMS swarakalibata - thumbnail/Image Resize dengan Codeignitter

Assalamualaikum,.. tambahkan pada config upload file/image menjadi seperti ini :
$config['image_library'] = 'gd2';
$config['source_image'] = 'asset/foto_berita/'.$hasil['file_name']; // thumbnail disimpan pada folder yang sama
$config['create_thumb'] = TRUE;
$config['maintain_ratio'] = TRUE;
$config['height']       = 622;
$this->load->library('image_lib', $config);
$this->image_lib->crop();
 
echo $hasil['raw_name']; // Simpan hasil crop/thumbnail ke database...

Assalamualaikum,.. 
Terima kasih master

Assalamualaikum,.. 
 
Saya coba terapkan pada CMS web portal kampus https://members.phpmu.com/files/detail/web-portal-kampus-responsove-dengan-framework-codeigniter-3x kok gak bisa ya.

Assalamualaikum,.. 
berikut perubahannya, mohon koreksinya
 
function list_berita_tambah(){
        $config['upload_path'] = 'asset/foto_berita/';
        $config['allowed_types'] = 'gif|jpg|png|JPG|JPEG';
        $config['max_size'] = '3000'; // kb
 
 
		$config['image_library'] = 'gd2';
$config['source_image'] = 'asset/foto_berita/'.$hasil['file_name']; // thumbnail disimpan pada folder yang sama
$config['create_thumb'] = TRUE;
$config['maintain_ratio'] = TRUE;
$config['height']       = 622;
$this->load->library('image_lib', $config);
$this->image_lib->crop();
 
 
 
        $this->load->library('upload', $config);
        $this->upload->do_upload('k');
        $hasil=$this->upload->data();

Assalamualaikum,.. coba cek di dalam folder asset/foto_berita gan,
harusnya ada 2 file saat upload foto berita.

Assalamualaikum,.. 
Sudah saya cek, dan hanya file asli yang terupload

Assalamualaikum,.. coba perbaiki jadi gini :
function list_berita_tambah(){
$config['upload_path'] = 'asset/foto_berita/';
$config['allowed_types'] = 'gif|jpg|png|JPG|JPEG';
$config['max_size'] = '3000'; // kb
$this->load->library('upload', $config);
$this->upload->do_upload('k');
$hasil=$this->upload->data();
 
$config['image_library'] = 'gd2';
$config['source_image'] = 'asset/foto_berita/'.$hasil['file_name']; // thumbnail disimpan pada folder yang sama
$config['create_thumb'] = TRUE;
$config['maintain_ratio'] = TRUE;
$config['height']       = 622;
$this->load->library('image_lib', $config);
$this->image_lib->crop();
 
$thumb_foto = $hasil['raw_name'].'_thumb'.$hasil['file_ext'];

Assalamualaikum,.. 
Ok..terima kasih min. Berhasil

Assalamualaikum,.. 
Sekarang yang menjadi masalah adalah hasil resize ternyata memotong gambar sebagian tidak hanya merubah ukuran. tetapi cropping sebagian gambar. Mohon solusinya

Assalamualaikum,.. 
crop tinggal diganti aja mas jadi resize
$this->image_lib->crop(); jadi $this->image_lib->resize();
