Limit FileUpload to certain filetypes

[mike_mcinerney]

     Is there a way to limit the Browse on a file upload to only go after certain types, in my case, PDFs ?

[mike_mcinerney]

Thanks for all the followon info - I'm going to close this question - Just to clarify, the question was can we somehow (proactively) only allow the user to select certain filetypes - and I think the answer is "No". 

Thanks all...

Hi,

Yes, It is possible. Create an attribute mime_type in context and bind the mime_type property of the file upload UI to that attribute. After browsing and selecting the file path and on click of Upload button, Read the mime type and display an error message if it is not the required type. for pdf mime type will be 'application\pdf' i guess.

Or,

bind the file name property of file upload UI to an attribute( file_name), read the file name in the onAction of upload button and read the file extension ( last occurrence of . dot) . and display error if it is not required type.

Hope this helps u.,

Regards,

Kiran

Thank you Kiran,

Yes, that is what I presently have coded (and yes,it is appliaction/pdf).

I was wondering if there was a way to only allow the user to select files of a certain mimetype.

I'd like to limit the selection, not warn them afterwards.

I think the poster wanted the file upload control to limit the file type to *.pdf for example, so that only those files are shown for the user to choose from. I'm not aware that it's possible. The file upload control will remember the previous setting but to default it, some fancy scripting would have to take place to which there probably isn't any interface in WDA. That said there are even differencies in how different browsers work.

Hi,

As far I knew there is no such provision in WDA as we cannot use Script. And even though if we set the file type say *.pdf, the user may change the file type to All files (* ) in the file open dialog.

So we can warn the user only after uploading.
