今天尝试了一下ASP 文件上传和表单共提交,发现也不像网上那么那么难!基于无组件的文件上传,网上的意见往往是文件上传和表单提交分开来做。

搜到了稻香老农的文件上传upload_5xsoft组建,发现里面有一个Form属性很好的解决了这个问题

 

test.html

<form action="test2.asp?number=www" method="post" enctype="multipart/form-data" >
  <p>&nbsp;</p>
  <p>
    <label>
    <input type="file" />
    </label>
  </p>
  <p>
    <label>
    <input type="text" />
    </label>
  </p>
  <p>
    <label>
    <select >
      <option value="2">1</option>
      <option value="4">3</option>
    </select>
    </label>
  </p>
  <p>&nbsp;</p>
  <p>
    <label>
    <input type="submit" value="提交" />
    </label>
    <input type="reset" value="重置" />

 

test2.html

<html><title>example</title>
<body>

<!--#include FILE="upload_5xsoft.inc"-->
<!--#include file="conn.asp"-->
<%
set upload=new upload_5xsoft
set file=upload.file("file1")
response.write upload.form("submit")&"<br>"
if file.fileSize>0 then
 file.saveAs Server.mappath("attachFile\"&file.FileName)
 response.write "<br>上传文件:"&file.FileName&" =>  OK!"
 response.write "<br>文件大小:"&file.FileSize
end if

sql="insert into test (name,age) values('"&file.FileName&"','"&upload.form("abc")&"')"

conn.execute(sql)

response.Write "<br>&nbsp;"&len(trim(upload.form("abc")))

response.Write "<br>&nbsp"&request.QueryString("number")
set file=nothing
set upload=nothing

%></body>
</html>

这样文件上传和表单提交可以完全同时进行

感谢稻香老农的upload_5xsoft.inc!!!!
