Title: How to allow file upload in an NT8 Webservice
Post by: debzidoodle on July 02, 2014, 12:31:06 PM

Hi All,

How can I upload a picture or file to a WebServiceMethod?  Ideally I would like to be able to upload more than one file at a time, but not required. 

It does not have to be done via a WebServiceMethod, but I am a little confused by this post http://www.nettalkcentral.com/index.php?option=com_smf&Itemid=36&topic=5150.0
The part that confuses me is using the web page, so do I create by own form in a routine? And if so how do I access the values and file upload from the form?

Thanks

Debra

Hi Debra,

create NetTalkPage and declare ST as a StringTheory object after that in page embed put code like this     
ST.SetValue(p_web.GetValue('_postdata_'))
ST.SaveFile('WHENEVERYOUWANT\WHATEVERYOUWANT.BIN')

Then with that file do it what you want.  :)

Best regards,

>> How can I upload a picture or file to a WebServiceMethod?

Because it's a webServiceMethod I presume you are uploading from a client which is not a Browser.

so there are 2 directions to take, based on the Client's method of choice.

a) do a POST from the client, including the file using "normal http post" techniques (which in say a NetTalk Web client means doing a
net.SetValue(fieldname,filename,true) [ from memory - so I don't know if the syntax is correct. ]

or
b) embed the file inside the incoming XML as a parameter, usually base64 encoded or something.

In the case of a) you can follow the instructions on the other thread - the incoming file is just in a Value.
In the case of b) you'd make the field a large string parameter (like any other parameter) and then you'd need to decode it and save it (probably using StringTheory.)

Cheers
Bruce

Thanks Bruce and Djordje.  With the explanation Bruce gave in the user group meeting #25 I got it worked out!

Thanks
