Thank you so much Lynne, that worked

.
I have another question pertinent to this page--I want to use it to add a form that only contains a type=file input field and upload that file on the server.
I have created the form but when trying to submit, I get the following error:
Your submission could not be processed because a security token was invalid.
I am pretty sure that I will need to pass the credentials as well--do you know how I can accomplish this?
TIA,
George

I got it! I am adding the code for the whole form below:
Code:
<form action="test.php" method="post" enctype="multipart/form-data">
<label for="file">Filename:</label>
<input type="file" name="file" id="file" />
<br />
<input type="submit" name="submit" value="Submit" />
<input type="hidden" name="s" value="{vb:raw session.sessionhash}" />
<input type="hidden" name="securitytoken" value="{vb:raw bbuserinfo.securitytoken}" />
</form>
These two hidden fields is what is needed.
