Hi,
Sorry ....
Here is the HTML form informations


<form action="load.html" name="form1" method="post" enctype="multipart
+/form-data">
<table>  
 <tr class="cell4">
   <td>Select EXCEL rate sheet</td>
   <td><input type="file" name="file" value=""></td>   
  </tr>
   <tr class="cell3">
   <td>&nbsp;</td>
   <td><input type="submit" name="upload" value="upload"></td>   
  </tr>      
</table>
</form>

and Embperl code used is


if((defined $fdat{file} && $fdat{file}) && $fdat{upload}) {
          $filename = "/tmp/sample.txt";
          open (FILE, "> $filename") || die("open failed: $!");
          while (read($fdat{file}, $buffer, 32768)) {
              print FILE $buffer || die("print test: $!");
          }
          close FILE || die("close test: $!");
}

If we remove enctype="multipart/form-data" form property, can see the form data (filename) after submiting the page.
includng enctype="multipart/form-data" in form will give undef filename. Any idea?
thanks

Compare your code to embperl upload ( Embperl-2.4.0/test/html/upload.htm )

In fact, I would use Embperl-2.4.0/test/html/upload.htm to figure things out

Testing for ref $fdat{upload} seems simplest
