[Resolved] How to not display an empty child view

I am trying to not display a parent taxonomy if the child view has no records found. For example:

My Child View:

[wpv-layout-start]
	[wpv-items-found]
	<!-- wpv-loop-start -->
	<wpv-loop>
      <div class="downloads">
         <a href="[types field='pdf-or-image-file'][/types]" target="_blank">[wpv-post-title]</a><br />
      </div>
	</wpv-loop>
	<!-- wpv-loop-end -->
	[/wpv-items-found]
	[wpv-no-items-found]
		<strong>[wpml-string context="wpv-views"]No items found[/wpml-string]</strong>
	[/wpv-no-items-found]
[wpv-layout-end]

Parent view:

[wpv-layout-start]
	[wpv-items-found]
	<!-- wpv-loop-start -->
		<wpv-loop> 
          <h4>[wpv-taxonomy-title]</h4> ----> (I want to not display this is nothing in the child view for this item)
          [wpv-view name="My Child View"] 
		</wpv-loop>
	<!-- wpv-loop-end -->
	[/wpv-items-found]
	[wpv-no-items-found]
		<strong>[wpml-string context="wpv-views"]No items found[/wpml-string]</strong>
	[/wpv-no-items-found]
[wpv-layout-end]

Currently, it still shows the parent wpv-taxonomy-title even when the child view is empty.

example:

PARENT
child
child
child

PARENT - I want childless parents not to show in the list

PARENT
child

I would like to have it not display if there isn't anything in the child view - but don't know how to reference it using an "evaluate" statement. I've tried checking if the pdf-or-image-file field is empty, but that doesn't work because it doesn't know to look in the child view.

Thanks in advance!

You can do this by evaluating on [wpv-taxonomy-post-count], like below:

[wpv-if evaluate="[wpv-taxonomy-post-count] != 0"]
    ... your child view and title here ...
[/wpv-if]

Please see https://toolset.com/documentation/views-shortcodes/#wpv-taxonomy-post-count for more information.

I had tried the [wpv-taxonomy-post-count] shortcode but it still didn't work. What eventually did work after much trial and error and research was registering the following in my functions.php.

add_shortcode("clean-view", "clean_view");
function clean_view($atts, $content) {
    $content = do_shortcode($content);
    $content = trim($content);
     
    return $content;
}

Then adding [clean-view] on the Compatibility tab, then using this in my parent view.

		
          [wpv-if h1="[clean-view][wpv-view name='my-child-view'][/clean-view]" evaluate="!empty($h1)"]
          <h4>[wpv-taxonomy-title]</h4>
           [wpv-view name="My Child View"]
          [/wpv-if] 

Unfortunately, since I updated Views & Types today to the newest releases and then WordPress to 4.3, this no longer works and I no longer get anything displayed. (If I remove the [wpv-if], it works - so it is just the check against the child view that isn't working.) I tried the method above again using [wpv-taxonomy-post-count] , but it still displays the childless parents.

BTW - When I try to see the Views 1.10 release notes, I get a blank page. Please help!

The nested short codes might be a problem with WordPress 4.3. I will suggest to use the following code, this is the same [clean-view] short code of yours, but with a slight modification:

add_shortcode("clean-view", "clean_view");
function clean_view($atts) {
    $view = $atts["view"];
    $content = render_view(array('title' => $view));
    $content = trim($content);
      
    return $content;
}

And use this short code as below:

[wpv-if h1="[clean-view view='My Child View']" evaluate="!empty($h1)"]
    <h4>[wpv-taxonomy-title]</h4>
    [wpv-view name="My Child View"]
[/wpv-if] 

Please notice the view name passed as the parameter to short code and render_view() function used in the short code function. Please read more about render_view() at https://toolset.com/documentation/user-guides/views-api/. Also remember to register [clean-view] in views settings.

The issue with release notes page (https://toolset.com/version/views-1-10/) has already been noticed and will be fixed soon.

Please let me know if I can help you with anything related.

Thank you! This did the trick. 🙂

I had help with this several months ago, but now the plugin has changed and this solution no longer works. I have tried changing my code to the following, but still am getting empty child views displayed.

[wpv-conditional h1="[clean-view view='Wine Fact Sheets']" if="( NOT(empty($h1)) )"]
          	<h4>[wpv-taxonomy-title]</h4>  
         	[wpv-view name="Wine Fact Sheets"] 
        [/wpv-conditional]
