One of our site members asked:
Any chance you guys could create a tutorial for to show us how to be more granular with meta queries?
For example, I have a grid of CPTs queried.
I want to query CPTs that match Manufacturer: 1 or 2 AND Material: stainless steel
Right now I can only do Manufacturer 1 AND 2 AND Stainless Steel (which would only be CPTs tagged as all 3) or Manufacturer 1 OR 2 OR Stainless Steel which would be CPTs that have any of one those.
For example, any way to say Manufacturer: 1, 2 AND Material: Stainless Steel?
Let's take a scenario where a product post type has a corresponding manufacturer and material custom fields.
Product 1Manufacturer: Manufacturer 2Materials: Copper, Iron
Product 2Manufacturer: Manufacturer 1Materials: Stainless steel
Product 3Manufacturer: Manufacturer 3Materials: Iron, Stainless steel
Product 4Manufacturer: Manufacturer 2Materials: Stainless steel
Requirement: Query CPT items that match Manufacturer: 1 or 2 AND Material: Stainless steeli.e., Product 2 and Product 4.
Custom field group:

Note that "Select multiple values" is on for both the fields.
This Pro tutorial provides the steps for adding a custom meta_query that will filter or limit the posts to match the following:
manufacturer (array) is Manufacturer 1 OR Manufacturer 2ANDmaterial (array) is Stainless Steel
in Bricks.
Step 1
Edit the Page/template in which you would like to show the CPT items with Bricks.
Inside a Section's Container, add a Posts element or set up Query Loop on a Container/Block (I typically use a Block element for query loops).
Edit the Query settings.
Post type: Products (change this to your post type, if different)
Posts per page: 100 (a large enough number that the total number of items of this CPT will never exceed in your site)
Do not set a meta query here because it is not possible to do what we want via the query popup controls.
Step 2
Add the following in child theme's functions.php or a code snippets plugin:
