input type='file', controlling the file type displayed.

[praveenhotha]

When I click the browse option, it lists all the files present in the folder but if i cancel after selecting for eg. an html file, the second time I click the browse button, it displays only the html files in the folder.

 

Can I do this on the first click of the browse button? I want to control the files shown as I know what type of files need to be uploaded.

what ever you want to do - give up - it can be circumvented - the only thing you can do reliably is to check teh mime type of teh uploaded file - if that is ok continue if not tell the user.

 

You can enhacne this with a nasty javascript check to see what the file extension is (but don't actually trust this) - if its not what you expect then you can prevent the upload.

I am checking the file extension for the file type,presently. Just thought that it might be more user friendly if only one particular type of files are displayed in the dialog(if it is possible).

 

Thanks.

You cannot specify the file type using html/javascript. You can if you use flash - http://www.swfupload.org/

you can use the accept attribute to specify what it should allow but again this cannot be relied upon and I have never used it so don't know how it acts on differing operating systems/browsers indeed I have read that some browsers completely ignore it...

 

<input type="file" accept="image/jpeg, text/css, image/png" />

I think what he wants to do is change what "File Type" is defaulted in the dialog box so that the USER doesn't have to sort through a folder full of .wav files when they are looking to upload a .txt file. Is this correct?
