private function fileUpload($name, $config = []){
$config['upload_path'] = './uploads/';
$config['encrypt_name'] = TRUE;
$config['file_ext_tolower'] = TRUE;
$config['allowed_types'] = 'jpg|jpeg|png';
$this->upload->initialize($config);
if ( ! $this->upload->do_upload($name))
{
$error = array('error' => true, 'message' => $this->upload->display_errors());
return $error;
}
else
{
return array('error' => false, 'upload_data' => $this->upload->data());
}
}
Create this private function in the controller just call this function when you have to upload the file with the name of the file field if you want some other config just pass config array to as a next parameter
$data = $this->fileUpload('site_logo_dark')
if($data['error']){
echo data['message']; // error message while uplaoding an file if have any
}else{
echo $data['upload_data']['file_name']; // return you a name of the file which you just upload it you can save it to the database
}
