Answer 1

for in above controller you are defining $data["avatar"] in if clause true part, but you are load the view in else part. how it will take....
thats way it given as undifened variable..
once check your controller.

Answer 2

in controller
class Upload_photo extends CI_Controller{
public $upload_model = "";
function __construct()
{
parent::__construct();
$this->load->helper(array('form', 'url'));
$this->load->model('upload_model');
}
public function index()
{
session_start();
if(isset($_FILES['file1']))
{
$u = $_SESSION['username'];
$config['upload_path'] = 'user/'.$u;
$config['allowed_types'] = 'gif|jpg|png';
$config['max_size'] = '30000';
$config['max_width'] = '1024';
$config['max_height'] = '768';
$this->load->library('upload',$config);
$filename = $_FILES['file1']['name'];
if(!$this->upload->do_upload('file1'))
{
echo "Error". $this->upload->display_errors();
return;
}
$config = array();
$config['image_library'] = 'gd2';
$config['source_image'] = 'user/'.$u.'/'.$filename ;
$config['new_image']= FCPATH . 'user/'.$u.'/Thumb/';
$config['create_thumb'] = TRUE;
$config['maintain_ratio'] = FALSE;
$config['width'] = 110;
$config['height'] = 110;
$this->load->library('image_lib',$config);
if(!$this->image_lib->resize())
{
echo $this->image_lib->display_errors();
}
else
{
$source = base_url().'user/'.$u.'/Thumb/'.$filename;
$data['avatar'] = $this->upload_model->update_photo($source);
$this->load->view('profile_view',$data);
}
}
}
}
try this in view
<div id="showimage" name='showimage'>
<?php
isset($avatar){
foreach ($avatar as $row)
{
echo $row;
}
}
?>
