Io uso jQuery Carica immagine come questo http://blueimp.github.com/jQuery-File-Upload/jQuery immagine Caricare - CodeIgniter

Qualsiasi aiuto?
Check: https://github.com/blueimp/jQuery-File-Upload/issues/ 517 Sembra un problema comune. – Marcus
Grazie, ma dove dovrei inserire questo codice dallo scorso post? Quando inserisco __construct() ottengo un errore: Messaggio: Proprietà indefinita: upload :: $ _ richiesta – Laky
Al github, il post menziona l'inserimento del codice all'inizio dell'azione - quindi suppongo nella funzione do_upload. Non riesco a mettermi alla prova adesso, mi dispiace =/ – Marcus
