Update on 22 Sep 2023: There’s a much simpler built-in method now. See this post.
In the Bricks Facebook group a user asks:
Is there a way, either using dynamic data or a custom PHP solution, to render an element based on if another element has content?
I’m sure there is, I just can’t get my head around it.
Use case:
I’m trying to use the Nestable Tabs element to display dynamic data. One of the tabs is using a query loop. If the query has no content/data, I want to hide the associated tab completely. I don’t want to use CSS to display: none – I want to complete stop the render of the tab.
I don’t mind using a custom class on the query loop or some a data attribute or something – but I can’t get it to work. Any pointers?
This can be done by creating a manual query with the same query parameters as what’s set in the builder, getting the count and checking against that using the Dynamic data condition.
The query in this example:
Step 1
Add the following in your child theme’s functions.php or a code snippets plugin:
function bl_get_posts_count() {
// custom wp_query
$args = array(
'post_type' => 'post',
'posts_per_page' => -1, // all matching posts
'category__in' => array( 2, 6 ), // posts that have these categories (not children)
'meta_query' => array(
array(
'key' => 'related_bios',
'value' => get_the_ID(),
// 'compare' => 'LIKE',
),
),
);
$posts = new WP_Query( $args );
// return the count of posts
return $posts->found_posts;
}Step 2
Apply this condition to the element(s) that you wish to be output only if there is at least 1 post that matches our query.

Great tut, If I’m using custom post type(cpt plugin) it will work? Thanks
Sridhar Katakam
Yes.
The method used to register the CPT does not matter.

Hi! How can I alter this function to exclude meta query? I have a custom post type that has two terms, "open status" and "closed status." I am trying to use the echo dynamic tag to display total post count, post count for open status, and post count for closed status.
I'm assuming I will need to add 3 different functions to code snippets, but do not know how to write these. Your help would be beyond appreciated.

Hey, awesome work,
what about if I need to set a condition for an author's page archive, where I want to show a section with inside a query loop of the author's latest posts, but don't want it to render if the author has no posts? I am trying to use your code, but I suck at php.
Thanks!

Hello
I am trying to achieve the same thing but with the "related product" element. The “related posts” element is a query loop that shows the feature image of Woocommerce products in a similar category or tag. How can I hide the Div completely if the query returns no products?
I am really stuck here, I have tried your solution but I cannot adapt it to the related posts element.
Could you help me out please ?
Thanks
I

I'm trying to do the same thing but show or hide a block based on the count of posts related to the current post via an ACF relationship field (show show block A if there is a single related post, show block B if there are multiple related posts). The field name of relationship field is "associated winery", so my code is as follows: https://pastebin.com/1Uhze2gN It doesn't work, and on the front end neither block gets output. Do I need to change something else to make this work with relationship fields?

So I'm querying some events in their own section inside a Taxonomy archive template. This taxonomy is essentially a global list of terms that applies to all my post types, so if someone accesses a specific terms archive page, 4-5 sections will populate content from various custom post types that share the same term. Since I have the query on an archive template, it automatically selects the term for me. So I simply chose Events as my post type for the query, and the template does the rest of the work pulling in the events related to the term archive.
How would I target this event Section to be hidden if there are no events with that term?

Can you suggest how to do this when the query loop is querying an ACF repeater rather than posts? So if a post has an ACF repeater field with multiple elements in the repeater, how can I count the number of elements in the reparter field for that post?

Eric Embacher
THanks for that. But this snippet is only to count if the repeater has any rows (or none)...I need a condition based on if the repeater as more than 3 rows. Can you help me modify it?
Sridhar Katakam
I wrote a little custom function for this but when it is used with a dynamic data condition, it doesn't work as expected when there are 0 rows. Sent a support email to Bricks. Will update when I hear back.

Awesome, thanks!

Hi Sridhar, I am trying to do this where i have a custom post trype called "events" i want to hide a section if there are no event posts. Is this the same PHP that you have provided above? Do i need to alter it?
Thanks, David

Hi David, there's now a easier and better way.
