Answer 1

Vérifiez vos accolades ici:

if(!$this->upload->do_upload()) echo $this->upload->display_errors(); else {

Il semble que vous mélangez des styles de syntaxe.

Answer 2

Essayez de retirer $fileName:

Au lieu de cela: $config['source_image'] = 'uploads/' . $fileName;

Utilisez ceci: $config['source_image'] = 'uploads/'

Answer 3

essayer cette

function _create_thumbnail($fileName) 
{ 
$this->load->library('image_lib'); 
     $config['image_library'] = 'gd2'; 
     $config['source_image'] = './uploads/' . $fileName;  
     $config['create_thumb'] = TRUE; 
     $config['maintain_ratio'] = TRUE; 
     $config['width'] = 210; 
     $config['height'] = 160; 
     $config['new_image'] = './uploads/'.$fileName; 

     $this->image_lib->initialize($config); 
     if(!$this->image_lib->resize()) echo 
$this->image_lib->display_errors(); 

}
