[Resolved] Conditional statements based on view shortcode attribute or NOT empty

I would like to display conditional text based on the results of a view shortcode with wpvposttag attributes assigned.

In one of my pages I am filtering and loading views based on assigned taxonomies:
hidden link

Here is an example of the shortcode tag loading a filtered view:
[wpv-view name="degree-listings" wpvposttag="academic programs, FST, major"]

What I would like to do is add conditional text if the view is not empty but nothing I am trying is working:
[wpv-conditional if="( '[wpv-view name='degree-listings' wpvposttag='academic programs, FST, major']' ne '' )"]Majors[/wpv-conditional]

[wpv-conditional if="(NOT(empty( '[wpv-view name='degree-listings' wpvposttag='academic programs, FST, major']' )) )"]Majors[/wpv-conditional]

The view [wpv-view name="degree-listings-by-level"] is basic and is used over and over in multiple places within the site and even multiple times on one page in many cases. What I want to avoid is the problem of having to create many views just for adding text in certain locations. If I can use the results of a view shortcode in a conditional statement within specific pages or in a parent view it would save me from having to do this.

For more context...below is additional page code as an example:

<h2>Academic Offerings by Degree</h2>
<h3>Majors</h3>
[wpv-view name="degree-listings" wpvposttag="major"]

<h3>Accelerated Programs</h3>
[wpv-view name="degree-listings" wpvposttag="accelerated"]

<h3>Masters Programs</h3>
[wpv-view name="degree-listings" wpvposttag="masters"]

<h2>Degrees by Department</h2>
<h3>Food Studies</h3>
Majors
[wpv-view name="degree-listings" wpvposttag="academic programs, FST, major"]
Masters
[wpv-view name="degree-listings" wpvposttag="academic programs, FST, masters"]
Certificates of Advanced Study
[wpv-view name="degree-listings" wpvposttag="academic programs, FST, cas"]

The above text within the tags need to be conditional based on the results of the views below them because if no degrees are displayed from the view "degree-listings" then the heading text is listed but with nothing below it. I need to change the text above to something like this:

<h2>Degrees by Department</h2>
<h3>Food Studies</h3>
[wpv-conditional if="( '[wpv-view name='degree-listings' wpvposttag='academic programs, FST, major']' ne '' )"]Majors[/wpv-conditional]
[wpv-view name="degree-listings-by-level" wpvposttag="academic programs, FST, major"]
[wpv-conditional if="( '[wpv-view name='degree-listings' wpvposttag='academic programs, FST, masters']' ne '' )"]Masters[/wpv-conditional]
[wpv-view name="degree-listings" wpvposttag="academic programs, FST, cas"]
[wpv-conditional if="( '[wpv-view name='degree-listings' wpvposttag='academic programs, FST, cas']' ne '' )"]Certificates of Advanced Study[/wpv-conditional]
[wpv-view name="degree-listings" wpvposttag="academic programs, FST, cas"]

Hi, Views aren't really meant to be used as the criteria for a conditional this way, and you're very likely to run into maximum nesting depth problems especially if you try to use another shortcode inside the View attribute. If I were trying to set this up, I would avoid conditionals if possible. Instead, use an arbitrary shortcode attribute in the View shortcode to set the header text, then output that text above the loop tags using the wpv-attribute shortcode. Here's an example (note the "heading" attribute):

[wpv-view name="degree-listings" wpvposttag="academic programs, FST, major" heading="Majors"]
[wpv-view name="degree-listings" wpvposttag="academic programs, FST, masters" heading="Masters"]
[wpv-view name="degree-listings" wpvposttag="academic programs, FST, cas" heading="Certificates of Advanced Study"]

Then in the Loop Output editor:

[wpv-layout-start]
	[wpv-items-found]
<strong>[wpv-attribute name="heading"]</strong>
	<!-- wpv-loop-start -->
	<wpv-loop>
		your loop stuff goes here
	</wpv-loop>
	<!-- wpv-loop-end -->
	[/wpv-items-found]
	[wpv-no-items-found]No items found[/wpv-no-items-found]
[wpv-layout-end]

Christian...Thanks!
What an elegant solution. It worked perfectly and I learned something new about the system. 🙂

Thanks so much for your time,
