Title: Controlling uploaded file names
Post by: Mike Grigsby on December 10, 2007, 09:20:48 PM: I'm having trouble wrapping my head around (and following the code backwards from the template) as to how to change the name of an uploaded file to be that of a date or customer number, for example. I wondered if someone has any suggestions or examples of how to do this.

For example, you might prompt a user to upload a file:

They enter: c:\somefolder\info.txt
It ends up in \web\uploads\info.txt

What I would like to do is have it end up something like: \web\uploads\[userID]_[date]

Anyone know how I can tweak the code to do this?

thats quite easy to achieve.

Look at the NetWebHandler in the Embeds under RenameFile.
Code: [Select]
ReturnValue = PARENT.RenameFile(p_name,p_filename) ! [Priority 5001] ReturnValue = PARENT.RenameFile(p_name, FORMAT(TODAY(), @D10-) & '_' & FORMAT(CLOCK(), @T04-) &'_'& p_filename) ! ReturnValue = PARENT.RenameFile(p_name, FORMAT(FIL:Date, @D10-) & '_' & FORMAT(FIL:Time, @T04-) &'_'& p_filename) ! End of "NetTalk Method Executable Code Section" RETURN ReturnValueResult in this sample is something like

YYYY-MM-DD_HH-MM-SS_Filename.EXT

BTW: did you get the dynamical footer working?

bye
Wolfgang

I can add all the headers I want, but I haven't figured out where to put footer code just yet. Thanks so much for your code example for the file upload stuff!

Post by: Wolfgang Orth on December 13, 2007, 02:08:57 PM: The header / footer is usualy a NetWebSource. Add a NetWebBorder. In the HTML-Tab (you can define a condition here) you add a HTML-formed comment pointing to a f:(file)variable which points to a text-file:



I have a folder called inc, where I store all txt that get included. Those files may comtain HTML-tags and may be modified at runtime, no recompile needed!

Post by: Mike Grigsby on December 13, 2007, 11:05:34 PM: Hi Wolfgang, thanks for you help! I wonder if you can help me understand how to pass a value to the renaming stuff. I was trying to use the system ID (e.g. fil:sysID) as the prefix to the file name.

I tried using a p_web.GetSessionValue... kind of deal, but it's not a web procedure, so that won't work.

After spending a lot of time on the issue, I can't think of a way to pass the sysID to the file renaming code. Have you encountered this before?

Post by: Wolfgang Orth on December 15, 2007, 10:36:59 AM: Hello Mike,

try this:
In the Procedure Setup-Embed of the NetWebSource Procedure to upload the file:

Quote
p_web.SetSessionValue('IDstring', .... Put the ID here .... )

I assume that you have the ID at your hand at this Embed.... ;-)

In the RenameFile-Embed of the WebHandler

Quote
ReturnValue = PARENT.RenameFile(p_name, FORMAT(TODAY(), @D10-) & '_' & FORMAT(CLOCK(), @T04-) &'_'& PARENT.GetSessionValue('IDstring') &'_'&p_filename)

Perhaps this works the way you want.

Bye
Wolfgang

>> I tried using a p_web.GetSessionValue... kind of deal, but it's not a web procedure, so that won't work.

You're actually _inside_ the p_web object at that point. (Indeed anything you embed in webHandler is inside that object.) So instead of using P_WEB use SELF. For example;

ReturnValue = PARENT.RenameFile(p_name, FORMAT(TODAY(), @D10-) & '_' & FORMAT(CLOCK(), @T04-) &'_'& SELF.GetSessionValue('IDstring') &'_'&p_filename)

Cheers
