Image Cropping in Codeigniter - php

Question

I want to crop my image upload and change my profile photo, but I don't know why it's not working even the picture was upload, profile picture not change, you must logout and picture was be change. this is my controller.
private $pk = 'nim';
private $table = 'mahasiswa';
public function update()
{
$nim = $this->session->userdata('nim');
if($_POST) {
$file = $this->upload();
if ($this->m_data->update($this->pk, $nim, $this->table, $this->field_data($file['data']))) {
redirect('Mahasiswa/Profil');
}
} else {
redirect('Mahasiswa/Formubah');
}
}
private function field_data($file = '')
{
$data['username'] = $this->input->post('username');
$data['password'] = $this->input->post('password');
if ($file != '') {
$data['foto'] = $file['file_name'];
}
return $data;
}
public function upload()
{
$config['upload_path'] = './assets/image/';
$config['allowed_types'] = 'gif|jpg|png';
$config['max_size'] = 0;
$config['remove_spaces'] = TRUE;
$this->load->library('upload', $config);
if ( ! $this->upload->do_upload('foto')){
return[
'data' => $this->upload->display_errors(),
];
} else {
$data = $this->upload->data();
$resize['image_library'] = 'gd2';
$resize['x_axis'] = 50;
$resize['y_axis'] = 50;
$resize['width'] = $img['config']['foto']['width'];
$this->image_lib->initialize($resize);
$this->image_lib->crop();
return [
'data' => $this->upload->data(),
];
}
}
i hope controller was enough. i forgot to tell, i use this show my picture. <?php echo base_url('assets/image/').$this->session->userdata('foto');?>

You are not properly implementing the library. Y forgot the library load and have not given its path.
$image_data = $this->upload->data();
$config['image_library'] = 'imagemagick';
$config['library_path'] = 'C:ImageMagick-7.0.1-3-portable-Q16-x86';//your library
$config['source_image'] = $image_data['full_path']; //get original image
$config['x_axis'] = 50;
$config['y_axis'] = 50;
$this->load->library('image_lib', $config);
if (!$this->image_lib->crop()) {
$this->handle_error($this->image_lib->display_errors());
}
