Upload File Codeigniter,can't detect variabel - php

Question

I'm trying to make upload image function on Codeigniter. but, when I trying to insert the image to the database. the variable can't be detected.
Here is my controller :
public function registrasi() {
//VALIDATION
$this->form_validation->set_rules('username', 'Username', 'required');
$this->form_validation->set_rules('email', 'Email', 'required|trim|valid_email|is_unique[tb_m_user.email]');
$this->form_validation->set_rules('password', 'Password', 'required|trim|min_length[3]|matches[konfirmasi_password]');
$this->form_validation->set_rules('konfirmasi_password', 'Retype Password', 'required|trim|matches[password]');
if($this->form_validation->run() == false) {
$this->session->set_flashdata('fail' , 'Registration Failed! Please Try Again');
$this->load->view('auth/registrasi');
}else{
//INSERT TO DATABASE
$username = $this->input->post('username');
$email = $this->input->post('email');
$password = password_hash($this->input->post('password'), PASSWORD_DEFAULT);
$pict = $_FILES['pict'];
//LIBRARY UPLOAD CONFIG
$config['upload_path'] = '/assets/dist/foto_validasi';
$config['allowed_types'] = 'jpg|png';
$config['file_name'] = date('ymd');
$this->load->library('upload', $config);
if(!$this->upload->do_upload('pict')){
echo "Upload Failed";
}else{
$pict = $this->upload->data('file_name');
}
$data = [
'user_name' => $username,
'email' => $email,
'password' => $password,
'role' => 'pengguna',
'img' => $pict,
'status_aktivasi' => 'tidak aktif',
'created_by' => 'SYSTEM',
];
$this->m_auth->registrasi($data, 'tb_m_user');
$this->session->set_flashdata('success' , 'Registration Successful! Please Login');
Redirect('Auth/login');
}
}
public function login() {
$this->form_validation->set_rules('email', 'Email', 'required');
$this->form_validation->set_rules('password', 'Password', 'required');
if ($this->form_validation->run() == false) {
$this->load->view('auth/login');
}else{
$this->postlogin();
}
}
Here is my form View :
<?= form_open_multipart('Auth/registrasi'); ?>
<div class="border-top mt-3">
<div class="ml-2">
<label class="mt-2">Upload Kartu Identitas</label>
</div>
<div class="input-group mb-3">
<input type="file" class="form-control" placeholder="Upload Foto Identitas" name="pict">
<div class="input-group-append">
<div class="input-group-text">
<span class="fas fa-file-image"></span>
</div>
</div>
</div>
<small class="text-danger"><?= form_error('foto') ?></small>
</div>
<?= form_close(); ?>
Here is the error : error
I even tried to change the variabel from:
$pict = $this->upload->data('file_name');
'img' => $pict,
to :
$pict2 = $this->upload->data('file_name');
'img' => $pict2,
but it gets another error :error2

If you want the upload feature to be required, you could modify the codes like this :
public function registrasi() {
//VALIDATION
$this->form_validation->set_rules('username', 'Username', 'required');
$this->form_validation->set_rules('email', 'Email', 'required|trim|valid_email|is_unique[tb_m_user.email]');
$this->form_validation->set_rules('password', 'Password', 'required|trim|min_length[3]|matches[konfirmasi_password]');
$this->form_validation->set_rules('konfirmasi_password', 'Retype Password', 'required|trim|matches[password]');
if($this->form_validation->run() == false) {
$this->session->set_flashdata('fail' , 'Registration Failed! Please Try Again');
$this->load->view('auth/registrasi');
}else{
//INSERT TO DATABASE
$username = $this->input->post('username');
$email = $this->input->post('email');
$password = password_hash($this->input->post('password'), PASSWORD_DEFAULT);
$pict = $_FILES['pict'];
//LIBRARY UPLOAD CONFIG
$config['upload_path'] = '/assets/dist/foto_validasi';
$config['allowed_types'] = 'jpg|png';
$config['file_name'] = date('ymd');
$this->load->library('upload', $config);
if(!$this->upload->do_upload('foto')){
echo "Upload Failed";
$this->session->set_flashdata('fail', $this->upload->display_errors() );
redirect( 'auth/registrasi' );
}else{
$pict = $this->upload->data('file_name');
$data = [
'user_name' => $username,
'email' => $email,
'password' => $password,
'role' => 'pengguna',
'img' => $pict,
'status_aktivasi' => 'tidak aktif',
'created_by' => 'SYSTEM',
];
$this->m_auth->registrasi($data, 'tb_m_user');
$this->session->set_flashdata('success' , 'Registration Successful! Please Login');
Redirect('Auth/login');
}
}
}
The $this->upload->display_errors() code will display the error message on the uploaded file that does not meet the requirements, so if the file is not uploaded then the registration data will not be saved.

Answer 2

Change the post field name as if(!$this->upload->do_upload('pict')){
if(!$this->upload->do_upload('pict')){ // You should change this

Answer 3

size attribute should be there in input field
<input type="file" size="1" class="form-control" placeholder="Upload Foto Identitas" name="pict">
