File Upload Type

Maybe a validation rule on the “Content Type” field of the attachment object? 

If memory serves, workflow rules don’t support attachments.  You will probably need Apex here.

Here’s a nice example to get you started:

hmmm… this is apex. Since this is the case, can we put together something more meaty using a visualforce page with a skuid:page visualforce component for all things related to attachments. ie. require an description upon uploading.

Shooting from the hip on this one.

Curious if anyone got a solution working here…and whether you did it with attachments to the object or the lookup field (to the custom skuid file object).

Has anyone come up with a solution for this one?

I have posted something like this before. 

A solution is Javascript. This prevents the user from picking other filetypes than specified. But this is not foolproof since JS could be disabled in the browser.

$('INPUT[type="file"]').change(function (event) {<br> var ext = this.value.match(/.(.+)$/)[1]; switch (ext) { case 'pdf': break; default: alert('This Filetype is not supported.'); this.value = ''; window.stop(); } });
