If you click on the Upload Control and select 'All Properties'... Under 'Data' you will find an option for 'Accept'.

 

Within here, you can select which values you wish to accept.  

Hi D,

 

 On the file upload properties Choose MIME type as Image/Jpeg and go to All Properties on the File Upload control and in the Basics tab go to the property 'accept' and select the 'value' from the options in the drop down. If the option you want for example jpg is not available then you can type that manually like image/jpg or image/jpeg.

 

Now what happens after saving the document is (it will only accept jpg images as attachments) and if any other files are attached it will ignore them and will not attach to the document, however no warning message is given.

 

Hope this helps.

Hello,

 

   I'm trying to do the same, except with PDF's.  I want to prevent users from adding anything but PDF's in the File Upload control.  I added "application/pdf" to both the "accept" and "mime" sections, and basically, it's working as you mentioned - if the file is a PDF, the document is saved; if the file is not a PDF, the document is not saved.

 

   This is totally unacceptable for the end users.  If someone selects anything other than a PDF, the file should not be accepted.

 

   Other than scrapping the File Upload control for the easier to use jQuery File Upload plugin, how can we prevent the file from being added?

 

Thanks, in advance!

Hi Steve,

 

there is no browser available which supports a restriction of mime-types or where it is possible to limit the selectable files in dialog.

But keep in mind that you still have to check the uploaded file if its really the type of file it "seems to be". Limiting the selectable files by their extension is not enough, because clever users would just rename their files. On the other hand a PDF can be a PDF without having a ".pfd"-Extension...

 

Just my two cents

Here is a simple idea how you could limit files (it is just HTML Code w/o XPages integration)

 

Thanks, Steve!

 

   The jQuery multiFile validation works perfectly fine, so browsers can properly prevent Uploads from adding a file.

   Before I found the jQuery multiFile validation, I used javascript very similar to what you proposed.

 

   I guess my bigger question is why is it so simple in traditional Notes/Domino, easier in jQuery, but messy with XPages?  Isn't XPages the supposed "fastest" way to building apps?  So, why does the "accept" property only seem to work on document submit and not when actually selecting a file.  Are users supposed to just accept this behavior?  Doesn't make sense.

 

   At this point, maybe I'll just scrap XPages until it becomes more mature, unless someone can help me figure this out.

 

Cheers!

Hi Steve,

 

I think there is a missunderstanding about XPages and their options, because this a an browser issue, and will never be fixed... Since IE 3.0 / Netscape 2.0 there is a property "accept" for the fileupload tag in HTML, but it was never ever implemented by any browser:

 

 

Please have a look here: dojox.form.FileUploader. It's the same as in jQuery as in other JS Frameworks. But theres always the same problem: If you want to stop users to upload ".exe" files, it does require more than checking the file extension; if a user renames f.e. "Virus.exe" to "Virus.pdf", he is able to upload this file. This is why the mimetype has to be checked on server side. The XPages provides the serverside validation of the uploaded file.
