Title: Example 26 file upload path problem
Post by: John Fligg on February 20, 2012, 03:04:49 AM

The demo works great until you change the location of the file.

Here is my code in the web handler which I have changed ....

 ! self.site.UploadsPath = clip(self.site.WebFolderPath) & '\alternate'
  self.site.UploadsPath = clip(self.site.AppPath) & '\somewhere' !\images'

and this is what is saved as the filename.

ewhere\PICT0036.JPG

If I use the WebFolderPath all works fine. However I cannot use that in a multi user scenario and need a specific path.

The above is only an example as I would not be using AppPath in reality.

BTW I note by checking the example data that someone has changed the path to "alternate" by uncommenting the code. This works great. I THINK that using anything but the WebFolder is an issue.

Thanks

John

Makes sense. Just use the clarion copy command after the file uploads and copy it where ever you want.

Hmm is that really safe? If you use the "common" web/uploads folder, what would happen if you got 2 files the same name?

I will be renaming the files using the record ID as part of that name but there is a chance that 2 users could post the same file in the upload folder at the same time.

The only way to limit that is to use the time in the filename I guess.

Thanks

bear in mind you can't turn around and _serve_ the pictures, unless they are inside the web folder somewhere.

Not quite sure what you mean by _serve_ the pictures Bruce but this is a disaster for me (I think).

For multi users, do I now have to create individual user folders within the web folder itself????

Basically imaging is a big (huge) part of my app and every user is goint o have to store a lot fo their own images.

Thanks

example 40 shows how to serve files outside the web folder.
But this is a bad idea for security reasons - if you don't understand exactly what you're doing you can create a hole which malicious users can exploit.

>> For multi users, do I now have to create individual user folders within the web folder itself?

up to you. multiple folders, or unique names - both work fine.

>> Basically imaging is a big (huge) part of my app and every user is goint o have to store a lot of their own images.

So, what's your "disaster" - they'll be inside the web folder. they have to be somewhere, so they may as well be there.

cheers

Sorry Bruce - a rather unprofessional response.

When you mentioned this I panicked and thought I could only have one folder. I have now created multiple user folders (as with the DATA) and all is working fine now.

Just that now when I create the user folder I have to do the same in the web folder. Not a problem, just one line of code in our office system.

BTW Any news on that FM3 issue?

Thanks

Bruce when you say "opening up a hole" - does that apply to DATA also???

Should everything go inside the web folder or are we just talking about images and the like?

Thanks

John

Does not apply to data, only -files- that will be served.
