ho già pulito la classe da cose che non mi servivano come l'aggiunta a db, a me serviva solo per scrivere sul server


Però avrei la necessità di poter inviare più di un file, presumo una decina, e questo script da quanto ci ho capito, non mi restituisce il nome del campo file
In particolare dovrei fare determinate operazioni in base al nome del campo file, quindi FILE1, FILE2, FILE3 ecc ecc

esiste un modo o una porzione di codice da aggiungere per far si di ricavare anche il nome del campo file?

tnx mille
