Classe_upload.php construct session empty -

I am using this class:

When I use the following code: < / P>

  $ repertoire_destination = strtolower ($ _ session ['login']); // DA clarification de la classes $ up = new telechargement ($ collection list, 'form1', 'file', 'conform_form'); // extension autorisà © es (sans les.) $ Extensions = array ("gif", "png", "jpg", "jpeg"); $ Up-> Set_exchange_accpatt ($ extension); $ Name_fichier = uniqid ($ _ session ['login']); // Renamage des Fitters (N mode incremental) C DA JAA Services Service $ Up-> Set_name_fichier ($ name_fichier, pathinfo ($ _ files ["file"] ["name"], pathinfo_expression)); $ Upflow & gt; Set_Renomme_fichier ($ name_fichier); $ Up- & gt; Set_radeim ('1920', '1200'); $ Up- & gt; Set_reidit ('160', '100', 'upload' 'stroller ($ _ session [' login ']).' / Thumbs'); // Tà © là© chargement $ up-> Upload ();   
 The saved file must be saved in the directory:  stroller ($ _ session ['login']);  which  $ _ session ['login']  
 but  
  
 But unfortunately, it sends an empty value.  
 When I use later:  
  $ up-> Set_reidit ('160', '100', 'upload' 'stroller ($ _ session [' login ']).' / Thumbs');   
  $ _ session ['login'])  has a  username .  
 Can anyone help me with it?   
 
 
  session_start ();  should be present / include all .php files while using sessions  
 plus this is your initial PHP tag  & lt ;? Below Php , should be at the very top (most of the time).  
  This is often overlooked.   
 More information about the sessions can be found on the PHP.net web site by following the link. >
