associare il comando delete ad un pulsante

**rays84** · 08-02-2006, 01:30

Salve, ho una pagina che mi visualizza un elenco di prodotti con
id - località - descrizione - foto1 - foto2 - foto3

e tramite un pulsante elimino tutta la scheda del prodotto + il link della foto presente nel database...l'unica cosa che non riesco a fare è quello di utilizzare lo stesso pulsante per eliminare fisicamente dal server (contemporamente) le tre foto abbinate da un id.

in altre discussioni ho trovato del codice per eliminare i file dal server, ma non so integrarli nella mia pagina...
al massimo si potrebbe fare un pulsante per ogni foto e cancellarle una alla volta...ma come si abbina un comando ad un pulsante?

posto il codice della mia pagina:

codice:
