Image resize does not work!

[eluser]behnampmdg3[/eluser]
Hello;

I use this script below to upload and re size images. Upload works fine but I can't see the re-sized image. In other words it doesn't re size!
I don't get any error messages from echo $this->image_lib->display_errors(); either. It says re sized so it has been successfully re sized. What am I doing wrong?

Thanks

Code:

<?php if ( ! defined('BASEPATH')) exit('No direct script access allowed');

class Gallery extends CI_Controller
{

public function index()
  {
   $data['title'] = "Gallary Page";
   $data['upload_data']="";
   $this->load->vars($data);
   if($this->input->post('submit'))
    {
     $this->do_upload();
    }
   $this->load_photos();
   $this->view_things();
  }

function do_upload()
  {
   $config['upload_path'] = 'uploads/';
   $this->load->model('add_photo_model');
   $data['new_photo'] = $this->add_photo_model->new_photo_name();
   $config['file_name']  = $data['new_photo'];

   if (!$this->upload->do_upload())
    {
     $data['upload_data'] = $this->upload->display_errors();
     $this->load->vars($data);
    }
   else
    {
     $photo['details']= array('upload_data' => $this->upload->data());
     $this->add_photo_model->add($data['new_photo']);
    
     $data['upload_data'] = "The photo has been uploaded successfully";
     $this->load->vars($data);
     $this->resize($data['new_photo']);
    }
  }

   echo $config['source_image'] = $photo;
   $config['create_thumb'] = TRUE;

   $config['width'] = 75;
   $config['height'] = 50;
    
   $this->load->library('image_lib', $config);

Try this in the upload part:

Code:

if (!$this->upload->do_upload())
  {
   $data['upload_data'] = $this->upload->display_errors();
   $this->load->vars($data);
  }
  else
  {
   //$photo['details']= array('upload_data' => $this->upload->data());
   $upload_data = $this->upload->data();
  
   $this->add_photo_model->add($data['new_photo']);

   $data['upload_data'] = "The photo has been uploaded successfully";
   $this->load->vars($data);
   //$this->resize($data['new_photo']);
   $this->resize($upload_data['full_path']);
  }

I'm not sure but maybe you better delete the "echo" parts in your
resize section (especially when setting the config values)
