$config = array(
'upload_path' => 'uploadPath',
'allowed_types' => 'jpg,jpeg',
'max_size' => 1500
);
$this->load->library('upload', $config);
if(isset($_FILES['field_name']) && $_FILES[field_name]['name'] != NULL)
if($this->upload->do_upload('field_name'))
{
$upload_data = $this->upload->data();
$data_to_insert = array(
'attachment_link' => 'uploadPath/'.$upload_data['file_name'],
'attachment_size' => $upload_data['file_size']
// u can add parameters as for ur table to save
);
$this->home_banner_model->insert_home_banner($data);
}
else
{
echo $this->upload->display_errors();
}
