How to upload images to a folder using Classic ASP?

In classic ASP you can not access the Request.Form method directly when you are receiving a POST with type multipart/form-data , so in order to interpret the data, it is necessary to make a parse of the information sent, a project that can help you is the Pure ASP Upload that you or you can install components on your server like ASP Upload that will add you a class that allows you to interpret this type of form and save your content to the server.

This code is written in VB5, so if your server does not have VB updated, you will need to update it to work.

Example HTML:

<FORM METHOD="POST" ENCTYPE="multipart/form-data" ACTION="uploadexmple.asp">
    <TABLE BORDER=0>
    <tr><td><b>Enter your fullname:</b><br><INPUT TYPE=TEXT SIZE=40 NAME="FULLNAME"></td></tr>
    <tr><td><b>Select a file to upload:</b><br><INPUT TYPE=FILE SIZE=50 NAME="FILE1"></td></tr>
    <tr><td><b>Save To:</b>&nbsp;&nbsp;
        Disk&nbsp;<INPUT TYPE=RADIO NAME="saveto" value="disk" checked>&nbsp;&nbsp;
        Database&nbsp;<INPUT TYPE=RADIO NAME="saveto" value="database">
    </td></tr>
    <tr><td align="center"><INPUT TYPE=SUBMIT VALUE="Upload!"></td></tr>
    </TABLE>
</FORM>

You can use the class clsUpload .

Once you give an include in it, you can simply do so:

ASP:

Dim objUpload 
Dim strArquivo, strCaminho

Set objUpload = New clsUpload
strArquivo= objUpload.Fields("file").FileName
strCaminho= "C:/ASP/sistema/imagens/" & strFile

objUpload("file").SaveAs strCaminho
Set objUpload = Nothing

HTML:

<form enctype="multipart/form-data" method="post" action="clsUpload.asp">
  <div>Enviar arquivo: </div>
  <div>
    <input type="file" NAME="file"> 
    <input type="button" name="enviar" value="Enviar">
  </div>
</form>
