codeigniter uploading image from form - codeigniter

Question

I have a field of my form (which is uploading personal picture). So the user selects image from pc and submit the form. I am later on handling all posted data via:
$this->input->post()
My method for insertion into database is:
public function add_user()
{
$data = array(
'membership'=>$this->input->post('membership_type'),
'fullname'=>$this->input->post('fullname'),
'username'=>$this->input->post('username'),
'password'=>md5($this->input->post('password')),
'email'=>$this->input->post('email'),
'city'=>$this->input->post('city'));
'profilepic'=>$this->input->post('profilepic'));
$this->db->insert('members',$data);
}
Now what I want to insert in the profilepic field is the path to the image on the server. I know am doing it wrong above because this way am inserting the picture posted to profilepic. I need some correction please. Is there a function that can perform upload and return the path? but again how can I associate the upload of picture with upload of user data?
Regards,
EDIT: Tried the code provided below and got this:
A PHP Error was encountered
Severity: Notice
Message: Use of undefined constant full_path - assumed 'full_path'

Please try this one:
public function add_user()
{
$config['upload_path'] = '/file_path/';
$config['allowed_types'] = 'gif|jpg|png|jpeg';
$this->load->library('upload', $config);
$this->upload->do_upload('profilepic');
$data_upload_files = $this->upload->data();
$image = $data_upload_files[full_path];
$data = array(
'membership'=>$this->input->post('membership_type'),
'fullname'=>$this->input->post('fullname'),
'username'=>$this->input->post('username'),
'password'=>md5($this->input->post('password')),
'email'=>$this->input->post('email'),
'city'=>$this->input->post('city'));
'profilepic'=>$image;
$this->db->insert('members',$data);
}

You can also try using 2 CI functions and check for the POST of the textual data as well as the image validation:
class SomeForm extends CI_Controller{
function add_user() //this function is your form
{
$this->load->view('templates/header');
$this->load->view('new_form_entry', array('error' => ' ' ));
$this->load->view('templates/footer');
}
function add_user_status() //this function is your form processing
{
$config['upload_path'] = './assets/images';
$config['allowed_types'] = 'gif|jpg|png';
//$config['max_size'] = '2000';
//$config['max_width'] = '340';
//$config['max_height'] = '190';
$this->load->library('upload', $config);
if ( ! $this->upload->do_upload())
{
//check for errors with the upload
$error = array('error' => $this->upload->display_errors());
$this->load->view('templates/header');
$this->load->view('new_form_entry', $error);
$this->load->view('templates/footer');
}
else
{
//upload the new image
$upload_data = $this->upload->data();
$image_name = $upload_data['file_name'];
if($_POST){
$data = array(
'author'=>$_POST['author'],
'name'=>$_POST['name'],
'image_thumb'=>'../assets/images/'.$image_name,
'video'=>$_POST['video'],
'title'=>$_POST['title'],
'body'=>$_POST['body'],
'created' => date('Y-m-d H:i:s')
);
//insert the new post
$this->your_database_model_name->insert_entry($data);
}
redirect(base_url().'SomeForm/index');
}
}
}
