how to display a dialog if user can't download file
- by tom smith
hi.
dealing with php/html/javascript.
i'm trying to figure out a good/best approach to allowing a user to download a file. i can have the traditional href link, that interfaces with the back end php app to download the file.
however, i want to have the app display some sort of dialog/alert if the user isn't able (basedon acl/permissions) to download the file... does this have to ba an ajax thing, as i don't want to do a page refresh...
thoughts/comments/pointers to code samples are appreciated.
thanks.
