The upload process functions like this – visitor sends the file to the server
using multipart form (enctype="multipart/form-data"). WhizBase first checks
if file upload is enabled in current virtual host setting (file wbsp.ssc). If it
is not, WBSP will generate error and terminate processing of the WBSP file. If
file upload is enabled, it checks if the WB_AllowMultipart variable is set to True in
the current WBSP file, and if it is, WhizBase reads settings from Upload section of
same file and process uploaded files (every multipart form can upload more than
one file at the time).
When WhizBase receives all files it saves them
following the instructions from Upload section and replace values of the
multipart fields (fields that had contained the uploaded files) with URL of saved file, and then it process the WBSP
file as any other. Multipart form must use
POST method.
Here is a very simple upload example (please read the comments in source code
below):
[FormFields]
WB_AllowMultipart=T #*Allow this wbsp file to accept uploaded files*#
WB_Command=R
[Upload]
WB_Disallow=![jpg,gif] #*disallow uploading of any file type but jpg and
gif*#
WB_UploadDir=/upload/ #*destination directory name (where uploaded files
will be saved)*#
WB_BaseURL=/upload/ #*path that will be added to file name to reference the
URL of the uploaded file*#
WB_Overwrite=F #*if set to false WhizBase will generate a unique name for
newly uploaded file if file with same name already exists in upload
directory*#
WB_MaxFSize=102400 #*Maximum size in bytes for single file that will be
accepted by WhizBase*#
WB_UploadLog=upload.log #*name of log file where WhizBase will keep track of
all uploads received by this file*#
