無組件上傳圖片之文件採用方案

首先，圖片在頁面中能查找選擇。設計表單頁面index.asp和上傳選擇頁upload.asp，upload.asp在index.asp中以iframe包含。

其次，所選圖片應能上傳到某文件夾。建立一文件夾uploadimg

最後，傳上去的圖片應如何引用？很顯然，採用UBB立即顯示。upload.asp的指向對象upfile.asp具有寫入UBB標籤的功能。


圖片上傳採用稻香老農的無組件上傳。所以upload.inc文件必不可少。

1，upload.inc（拷貝以下文本框的所有代碼）
<SCRIPT RUNAT=SERVER LANGUAGE=VBSCRIPT> dim upfile_5xSoft_Stream Class upload_5xSoft dim Form,File,Version Private Sub Class_Initialize dim iStart,iFileNameStart,iFileNameEnd,iEnd,vbEnter,iFormStart,iFormEnd,theFile dim strDiv,mFormName,mFormValue,mFileName,mFileSize,mFilePath,iDivLen,mStr Version="" if Request.TotalBytes<1 then Exit Sub set Form=CreateObject("Scripting.Dictionary") set File=CreateObject("Scripting.Dictionary") set upfile_5xSoft_Stream=CreateObject("Adodb.Stream") upfile_5xSoft_Stream.mode=3 upfile_5xSoft_Stream.type=1 upfile_5xSoft_Stream.open upfile_5xSoft_Stream.write Request.BinaryRead(Request.TotalBytes) vbEnter=Chr(13)&Chr(10) iDivLen=inString(1,vbEnter)+1 strDiv=subString(1,iDivLen) iFormStart=iDivLen iFormEnd=inString(iformStart,strDiv)-1 while iFormStart < iFormEnd iStart=inString(iFormStart,"name=""") iEnd=inString(iStart+6,"""") mFormName=subString(iStart+6,iEnd-iStart-6) iFileNameStart=inString(iEnd+1,"filename=""") if iFileNameStart>0 and iFileNameStart<iFormEnd then iFileNameEnd=inString(iFileNameStart+10,"""") mFileName=subString(iFileNameStart+10,iFileNameEnd-iFileNameStart-10) iStart=inString(iFileNameEnd+1,vbEnter&vbEnter) iEnd=inString(iStart+4,vbEnter&strDiv) if iEnd>iStart then mFileSize=iEnd-iStart-4 else mFileSize=0 end if set theFile=new FileInfo theFile.FileName=getFileName(mFileName) theFile.FilePath=getFilePath(mFileName) theFile.FileSize=mFileSize theFile.FileStart=iStart+4 theFile.FormName=FormName file.add mFormName,theFile else iStart=inString(iEnd+1,vbEnter&vbEnter) iEnd=inString(iStart+4,vbEnter&strDiv) if iEnd>iStart then mFormValue=subString(iStart+4,iEnd-iStart-4) else mFormValue="" end if form.Add mFormName,mFormValue end if iFormStart=iformEnd+iDivLen iFormEnd=inString(iformStart,strDiv)-1 wend End Sub Private Function subString(theStart,theLen) dim i,c,stemp upfile_5xSoft_Stream.Position=theStart-1 stemp="" for i=1 to theLen if upfile_5xSoft_Stream.EOS then Exit for c=ascB(upfile_5xSoft_Stream.Read(1)) If c > 127 Then if upfile_5xSoft_Stream.EOS then Exit for stemp=stemp&Chr(AscW(ChrB(AscB(upfile_5xSoft_Stream.Read(1)))&ChrB(c))) i=i+1 else stemp=stemp&Chr(c) End If Next subString=stemp End function Private Function inString(theStart,varStr) dim i,j,bt,theLen,str InString=0 Str=toByte(varStr) theLen=LenB(Str) for i=theStart to upfile_5xSoft_Stream.Size-theLen if i>upfile_5xSoft_Stream.size then exit Function upfile_5xSoft_Stream.Position=i-1 if AscB(upfile_5xSoft_Stream.Read(1))=AscB(midB(Str,1)) then InString=i for j=2 to theLen if upfile_5xSoft_Stream.EOS then inString=0 Exit for end if if AscB(upfile_5xSoft_Stream.Read(1))<>AscB(MidB(Str,j,1)) then InString=0 Exit For end if next if InString<>0 then Exit Function end if next End Function Private Sub Class_Terminate form.RemoveAll file.RemoveAll set form=nothing set file=nothing upfile_5xSoft_Stream.close set upfile_5xSoft_Stream=nothing End Sub Private function GetFilePath(FullPath) If FullPath <> "" Then GetFilePath = left(FullPath,InStrRev(FullPath, "/")) Else GetFilePath = "" End If End function Private function GetFileName(FullPath) If FullPath <> "" Then GetFileName = mid(FullPath,InStrRev(FullPath, "/")+1) Else GetFileName = "" End If End function Private function toByte(Str) dim i,iCode,c,iLow,iHigh toByte="" For i=1 To Len(Str) c=mid(Str,i,1) iCode =Asc(c) If iCode<0 Then iCode = iCode + 65535 If iCode>255 Then iLow = Left(Hex(Asc(c)),2) iHigh =Right(Hex(Asc(c)),2) toByte = toByte & chrB("&H"&iLow) & chrB("&H"&iHigh) Else toByte = toByte & chrB(AscB(c)) End If Next End function End Class Class FileInfo dim FormName,FileName,FilePath,FileSize,FileStart Private Sub Class_Initialize FileName = "" FilePath = "" FileSize = 0 FileStart= 0 FormName = "" End Sub Public function SaveAs(FullPath) dim dr,ErrorChar,i SaveAs=1 if trim(fullpath)="" or FileSize=0 or FileStart=0 or FileName="" then exit function if FileStart=0 or right(fullpath,1)="/" then exit function set dr=CreateObject("Adodb.Stream") dr.Mode=3 dr.Type=1 dr.Open upfile_5xSoft_Stream.position=FileStart-1 upfile_5xSoft_Stream.copyto dr,FileSize dr.SaveToFile FullPath,2 dr.Close set dr=nothing SaveAs=0 end function End Class </SCRIPT> [Ctrl+A 全部選擇 提示：你可先修改部分代碼，再按運行]


2，表單頁面index.asp。注意包含的上傳選擇頁upload.asp

<form name="form_name" method="POST" action="add.asp">
<textarea cols="100" name="cn_content" rows="18" width="100%"></textarea>
</form>

<iframe border="0" frameBorder="0" noResize scrolling="no" width="100%" src="upload.asp"></iframe>

3，上傳選擇頁upload.asp 注意： enctype="multipart/form-data" 

<form name="form" method="post" action="upfile.asp" enctype="multipart/form-data">
<input type="hidden" name="filepath" value="uploadimg">
<input type="hidden" name="act" value="upload">
<input type="file" name="file1" size=40>
<input type="submit" class=button name="Submit" value="上傳圖片" οnclick="parent.document.forms[0].Submit.disabled=true">類型：gif,jpg，限制：100K
</form>

4，最後一 個文件 upfile.asp 主要作用：生成圖片名，並將圖片上傳，同樣也要將UBB標籤寫入index.asp中的textarea中。
（拷貝以下文本框的所有代碼）

<!--#include file="upload.inc"--> <html> <head> <title>文件上傳</title> </head> <body> <script> parent.document.forms[0].Submit.disabled=false; </script> <% dim upload,file,formName,formPath,iCount,filename,fileExt set upload=new upload_5xSoft ''建立上傳對象 formPath=upload.form("filepath") ''在目錄後加(/) if right(formPath,1)<>"/" then formPath=formPath&"/" response.write "<body>" iCount=0 for each formName in upload.file ''列出所有上傳了的文件 set file=upload.file(formName) ''生成一個文件對象 if file.filesize<100 then response.write "請選擇你要上傳的文件　[ <a href=# οnclick=history.go(-1)>重新上傳</a> ]" response.end end if if file.filesize>100*1000 then response.write "文件大小超過了限制100K　[ <a href=# οnclick=history.go(-1)>重新上傳</a> ]" response.end end if fileExt=lcase(right(file.filename,4)) uploadsuc=false Forum_upload="gif,jpg,png" Forumupload=split(Forum_upload,",") for i=0 to ubound(Forumupload) if fileEXT="."&trim(Forumupload(i)) then uploadsuc=true exit for else uploadsuc=false end if next if uploadsuc=false then response.write "文件格式不正確　[ <a href=# οnclick=history.go(-1)>重新上傳</a> ]" response.end end if randomize ranNum=int(90000*rnd)+10000 filename=formPath&year(now)&month(now)&day(now)&hour(now)&minute(now)&second(now)&ranNum&fileExt if file.FileSize>0 then ''如果 FileSize > 0 說明有文件數據 file.SaveAs Server.mappath(FileName) ''保存文件 for i=0 to ubound(Forumupload) if fileEXT="."&trim(Forumupload(i)) then response.write "<script>parent.form_name.cn_content.value+='[img]"&FileName&"[/img]'</script>" exit for end if next iCount=iCount+1 end if set file=nothing next set upload=nothing ''刪除此對象 Htmend iCount&" 個文件上傳結束!" sub HtmEnd(Msg) set upload=nothing response.write "上傳成功 [ <a href=# οnclick=history.go(-1)>繼續上傳</a>]" response.end end sub %> </body> </html> [Ctrl+A 全部選擇 提示：你可先修改部分代碼，再按運行]

當然，保持圖片的文件夾uploadimg不能少
