K# help needed

Hi,

I need a little help with k# if possible? In a custom layout for a 'Notification e-mail' under CMS Desk > Forms, I am trying to output n/a if a given field is empty. (The field is an upload file field). So if no file has been selected for upload, display "n/a", else display the filename.

This is what I am using, but it isn't working. It either shows the filename or nothing at all.

{% display = "n/a"; if (Fieldname != "") {display = Remove(Fieldname, 0, LastIndexOf(Fieldname, "/") + 1)} display %} is put in there by Kenitco CMS, not me.

Thanks,

Matt

RE:K# help needed

Hi Matt,

I already ran with this problem before (Fieldname != "" comparison).

You can evaluate if something is empty with the IsEmpty() method. Use it as follows:

{% IfEmpty(Fieldname, "n/a", Remove(Fieldname, 0, LastIndexOf(Fieldname, "/") + 1) %}

First parameter is the object to evaluate if empty. Second parameter is what is returned if evaluated object is null. Third parameter is what is returned if evaluated object is not empty.

I suggested you take a look at this. Really helpful :)

Regards,
Nicolas
