Answer 1

you are not using enctype='multipart/form-data'
try this
<?=form_open_multipart('Admin/add_news',['class'=>'form'],['aid'=>$this->session->userdata('adminId')])?>

Answer 2

You need to use form_open_multipart instead of form_open so that enctype can be added in form
Change
<?=form_open('Admin/add_news',['class'=>'form'],['aid'=>$this->session->userdata('adminId')])?>
to:
<?=form_open_multipart('Admin/add_news',['class'=>'form'],['aid'=>$this->session->userdata('adminId')])?>

Answer 3

You need to use multipart/form-data for file uploading.
So use form_open_multipart instead of form_open.
echo form_open_multipart('Admin/add_news');

Answer 4

function upload_add($name) { $this->load->helper('form'); $config['upload_path'] = 'upload/add_image/'; $config['allowed_types'] = 'gif|jpg|png'; $config['max_size'] = '30000'; $config['max_width'] = '102400'; $config['max_height'] = '76800'; $this->load->library('upload', $config); $this->upload->initialize($config); if (!$this->upload->do_upload($name)) { $data = array('msg' => $this->upload->display_errors()); } else { $data = array('msg' => "success"); $databasea['upload_data'] = $this->upload->data(); $this->load->library('image_lib'); return $databasea['upload_data']['file_name']; } return ''; }
