Persits ASPUpload is a server-side component that can be used to upload files
from a client's machine to the server, under your domain.
How do you use Persits ASPUpload?
The following is an example of using the ASPUpload component to upload a file:
<%
'Create an
instance of our ASPUpload object.
Set uploadObj =
Server.CreateObject("Persits.Upload")
'We need to
catch any errors
On Error Resume Next
uploadObj.Save Server.MapPath(".")
If (Err <> 0) Then
Response.Write "An error occured: " & Err.Description
End If
%>
The standard Request.Form collection becomes
unusable when the Persits.Upload object is
instantiated, to access the values of the Form collection, use something similar
to this:
<%
formValue =
uploadObj.Form("formField")
'Where
formField is a field input that was posted.
%>
Posting a Form
When you post a form to your script, if it contains a file field (<input
type="file" />), you need to specify an encoding type. This can be
done as follows:
<form action="..." method="post" enctype="multipart/form-data">
Using SELECT (MULTIPLE)
fields with ASPUpload
If you use a SELECT field in your posted form,
with the MULTIPLE attribute, ASPUpload will store
each selected value as an item in uploadObj.Form,
and each item can be accessed individually:
<%
'Enumerate the
Upload.Form collection.
For Each Item In Upload.Form
If (Item.Name
= "select-field-name") Then
'Do something.
Else
'Other Items.
End If
Next
%>
Permissions
The permissions on your hosting account are setup to allow scripts to
operate in a secure manner. Uploading files will work when the Save path
is one that is under your domain. Trying to save to files outside of your
domain will result in an access violation and your script will finish in error.
