This article is provided by PHP Chinese website and introduces how to use asp to upload binary images and save them to the access database.
The specific implementation code is as follows:
Save image user upload page (3.asp):
<html> <body> <center> <form name="mainForm" enctype="multipart/form-data" action="2.asp" method=post> <input type=file name=mefile><br> <input type=submit name=ok value="OK"> </form> </center> </body> </html>
Save image page (2.asp) asp):
<% response.buffer=true formsize=request.totalbytes formdata=request.binaryread(formsize) bncrlf=chrB(13) & chrB(10) pider=leftB(formdata,clng(instrb(formdata,bncrlf))-1)datastart=instrb(formdata,bncrlf & bncrlf)+4 dataend=instrb(datastart+1,formdata,pider)-datastart mydata=midb(formdata,datastart,dataend)set connGraph=server.CreateObject("adodb.connection") connGraph.open"provider=microsoft.jet.oledb.4.0;data source=E:\PHP\valve.mdb;" set rec=server.createobject("ADODB.recordset") rec.Open "SELECT * FROM [user]",connGraph,1,3 rec.addnew rec("img").appendchunk mydata rec.update rec.close set rec=nothing set connGraph=nothing %>
Image reading page (1.asp): This page does not allow html code, otherwise garbled characters will appear!
<% set rs=server.createobject("ADODB.recordset") sql="" rs.open strsql,connGraph,1,1 Response.ContentType = "image/*" Response.BinaryWrite rs("").getChunk(8000000) %>
The number in getChunk() must be greater than or equal to the number of bytes of the image to be displayed, otherwise the image will not be displayed completely!
Image display page (4.asp):
<html> <body> <img src="1.asp?id=要显示的图片id"> </body> </html>
