Ciao a tutti,
Sto creando un sito in php (il primo) e devo ammettere che qualche problemino lo incontro..
Uno e' questo..
Ho trovato in rete questo script in php che ti permette di effettuare l'upload con visione dell'immagine caricata.
Io vorrei reindirizzare l'immagine verso una mia pagina php e non so come fare ma cosa piu' importante vorrei che l'immagine uplodata restasse salvata in modo che quando l'utente si logga la trovasse li ,nel suo profilo..
vi posto lo script
