如何把图片上传到数据库中并显示出来？
upload.htm
\’ 上传页面.
<html>
<body>
<p align=\”center\”>千花飞舞之图片上传</p><center> <form name=\”mainForm\” enctype=\”multipart/form-data\”
\’ 这个Form属性是得到上传的数据的关键.action=\”process.asp\” method=post> <input type=file name=mefile><br> <input type=submit name=ok value=\”上传\”> </form> </center> </body></html>
process.asp
\’ 处理浏览器中送来的数据.
<% response.buffer=true formsize=request.totalbytes formdata=request.binaryread(formsize) bncrlf=chrB(13) & chrB(10) divider=leftB(formdata,clng(instrb(formdata,bncrlf))-1) datastart=instrb(formdata,bncrlf & bncrlf)+4 dataend=instrb(datastart+1,formdata,divider)-datastart mydata=midb(formdata,datastart,dataend) set connGraph=server.CreateObject(\”ADODB.connection\”) connGraph.ConnectionString=\”driver={Microsoft Access Driver (*.mdb)};
DBQ=\” & server.MapPath(\”images.mdb\”) & \”;uid=;PWD=;\” connGraph.Open set rec=server.createobject(\”ADODB.recordset\”) rec.Open \”select * from [images] where id is null\”,connGraph,1,3 rec.addnew rec(\”img\”).appendchunk mydata rec.update rec.close set rec=nothing set connGraph=nothing %>
showimg.asp
\’ 显示图片.<% set connGraph=server.CreateObject(\”ADODB.connection\”) connGraph.ConnectionString=\”driver={Microsoft Access Driver (*.mdb)};
DBQ=\” & server.MapPath(\”images.mdb\”) & \”;uid=;PWD=;\” connGraph.Open set rec=server.createobject(\”ADODB.recordset\”) strsql=\”select img from images where id=\” & trim(request(\”id\”)) rec.open strsql,connGraph,1,1 Response.ContentType = \”image/*\”
\’ 在输出到浏览器之前一定要指定Response.ContentType = \”image/*\”,以便正常显示图片.Response.BinaryWrite rec(\”img\”).getChunk(7500000) rec.close set rec=nothing set connGraph=nothing %>[1]
