Upload, rename del file e controllo estensione

[Cefano]

ciao a tutti.

volevo chiedere se qualcuno sa come rinominare il file dopo averlo trasferito sul server e come applicare un controllo sulle estensioni per permettere che i file caricati siano sempre jpg...lo script che permette l'upload è il seguente.....




<%Sub BuildUploadRequest(RequestBin) PosBeg = 1 PosEnd = InstrB(PosBeg,RequestBin,getByteString(chr(13))) boundary = MidB(RequestBin,PosBeg,PosEnd-PosBeg) boundaryPos = InstrB(1,RequestBin,boundary) Do until (boundaryPos=InstrB(RequestBin,boundary & getByteString("--"))) Dim UploadControl Set UploadControl = CreateObject("Scripting.Dictionary") Pos = InstrB(BoundaryPos,RequestBin,getByteString("Conte nt-Disposition")) Pos = InstrB(Pos,RequestBin,getByteString("name=")) PosBeg = Pos+6 PosEnd = InstrB(PosBeg,RequestBin,getByteString(chr(34))) Name = getString(MidB(RequestBin,PosBeg,PosEnd-PosBeg)) PosFile = InstrB(BoundaryPos,RequestBin,getByteString("filen ame=")) PosBound = InstrB(PosEnd,RequestBin,boundary) If PosFile<>0 AND (PosFile<PosBound) Then PosBeg = PosFile + 10 PosEnd = InstrB(PosBeg,RequestBin,getByteString(chr(34))) FileName = getString(MidB(RequestBin,PosBeg,PosEnd-PosBeg)) UploadControl.Add "FileName", FileName Pos = InstrB(PosEnd,RequestBin,getByteString("Content-Type:")) PosBeg = Pos+14 PosEnd = InstrB(PosBeg,RequestBin,getByteString(chr(13))) ContentType = getString(MidB(RequestBin,PosBeg,PosEnd-PosBeg)) UploadControl.Add "ContentType",ContentType PosBeg = PosEnd+4 PosEnd = InstrB(PosBeg,RequestBin,boundary)-2 Value = MidB(RequestBin,PosBeg,PosEnd-PosBeg) Else Pos = InstrB(Pos,RequestBin,getByteString(chr(13))) PosBeg = Pos+4 PosEnd = InstrB(PosBeg,RequestBin,boundary)-2 Value = getString(MidB(RequestBin,PosBeg,PosEnd-PosBeg)) End If UploadControl.Add "Value" , Value UploadRequest.Add name, UploadControl BoundaryPos=InstrB(BoundaryPos+LenB(boundary),Requ estBin,boundary) Loop End Sub Function getByteString(StringStr) For i = 1 to Len(StringStr) char = Mid(StringStr,i,1) getByteString = getByteString & chrB(AscB(char)) Next End Function Function getString(StringBin) getString ="" For intCount = 1 to LenB(StringBin) getString = getString & chr(AscB(MidB(StringBin,intCount,1))) Next End Function%>

Uno scritp scritto così non ha alcun senso...
Devi comunque usarne un altro:

scusami...so che è disordinato..ma io l'ho incollato perfettamente formattato.. si è fatto cosi dopo

[Cefano]

se vuoi aiutarmi ti invio prorpio il file ti va?

Io uso SmartUpload ma ho scoperto che con 2/3 immagini troppo grandi (scattate con la fotocamera) blocca il server/sito poiché deve rimpicciolirle, rinominarle e uplodarle... Lo script di baol74 soffre di questi problemi? Ve lo chiedo perché se no non vale la pena lavorarci per stare punto e a capo....

Grazie

il codice lo devi mettere tra i tag code, pulsante "#"

 così ti appare in questa finestra tutto bello formattato

[Cefano]

Perfetto..allora rinnovando le mie scusa per la scorrettaformattazione del codice provo di nuovo a postarlo...non si sa mai che un'anima pia mi da una mano....
