Vvupload - error

[ThierryC]

Hi

i'm on Valence 4.2
I'm Trying to do exactly the same as rkanemayer described here .. and that is determining the filename that was uploaded, and adding some timestamp to avoid duplicate names..
i'm doing exactly the same as is described in his thread.. but when a try to retrieve the localFilename with the vvgetS , i get a blank value , however when i look in the file Valence42t/vvsessvars : it is there.??
contents from the file.
content from the VVSESSVARS

VVSESSID:5168CF9...
VVVARIABLE: VVUPLOAD_fileName
VVVALUE:barco.csv 

in the error-app i noticed that an error was logged :

In the case of an upload you cannot use vvIn_char('sid'). Your upload program will automatically be passed the "sid" from vvupload. So in your program, you need to accept the sid parameter (64a) and then use that to pass to vvUtility_getSessVar.

[ThierryC]

Sorry..; your answer is not clear for me .. .. i still don't have a clue how i can pass the sid and extra fields to the rpg program..

is it possible to give an example...


(i've modified the exupload1 example panel to contain more fields.. i want those fields to be passed to the rpg program.. )



thx

Because the file is uploaded with the variables as a multi-part form the standard vvIn's don't work. VVUPLOAD has a provision to pass the sid as an entry parameter to your EXUPLOAD1 program. So in your program where you have vvIn_char('sid'), take that out and just make sid and entry parameter to the program defined as 64a. Then VVUPLOAD will automatically pass it to EXUPLOAD1.

Might also be worth noting that any other variables sent from the front end along with the uploaded file will be saved as session variables, which you can retrive via vvUtility_getSessVar(variableName:sid).

Hi all,

Thx, i've made it work with your help.. life can be simple...

(it might be worth adding a note in the manuals, or providing an example for this somewhat other way of getting the parms in the rpg-pgm..)


thx

Hi Thierry,

Thanks for the suggestion. We made this topic a blog post and linked to it as our "tip of the month" in this month's Valence Newsletter.
