Here is how I do it.
Edit- Class Construct
class Team extends CI_Controller {
function __construct()
{
parent::__construct();
$this->load->library('form_validation');
$this->load->helper(array('form', 'url'));
$this->load->model('team_model');
}
public function do_upload()
{
$config['upload_path'] = './uploads/';
$config['allowed_types'] = 'gif|jpg|png';
$config['max_size'] = 100;
$config['max_width'] = 1024;
$config['max_height'] = 768;
$this->load->library('upload', $config);
if ( ! $this->upload->do_upload('userfile1'))
{
$data['errors'] = array('error' => $this->upload->display_errors());
$data['client_Id']=$this->team_model->getUserId($email);
$data['pic']=$this->team_model->getImage($data['client_Id']['id']);
// Here I load my Views
}
else
{
$upload_data = $this->upload->data();
$file_name=$upload_data['file_name'];
$email=$this->session->userdata['email'];
$data['client_Id']=$this->team_model->getUserId($email);
$data['pic']=$this->team_model->getImage($data['client_Id']['id']);
// If there is no image insert one other wise update
if($data['pic']['image']!=''){
$this->team_model->updateEmployeeImage($data['pic']['id'],$file_name);
$data['success']='Congratulations! Image Updated Successfully';
}else{
$this->team_model->InsertEmployeeImage($data['client_Id']['id'],$file_name);
$data = array('upload_data' => $this->upload->data());
$data['success']='Congratulations! Image Uploaded Successfully';
}
$file_name=$upload_data['file_name'];
$email=$this->session->userdata['email'];
$data['client_Id']=$this->team_model->getUserId($email);
$data['pic']=$this->team_model->getImage($data['client_Id']['id']);
// Here I load my Views
}
}
}
Edit- Model Functions
public function InsertEmployeeImage($id,$image){
$Image=array(
'id' => '',
'team_id' => $id,
'image' => $image
);
$this->db->insert('teams_image',$Image);
return ;
}
public function updateEmployeeImage($id,$img){
$this->deleteOldImage($id);
$pic=array(
'image' => $img
);
$this->db->WHERE('id',$id)->update('teams_image',$pic);
}
