Problem: I have a View of taxonomy terms that I am using to create a list of links to different pages that each contain a filtered View. The links work well now, but some of the Views on these pages have no results. If the View contains no results, I would like to hide the link to that page.
Solution: Use a View as a conditional to determine whether or not results are found. If results are found, display the link. If no results are found, display nothing. Use shortcode attributes and the wpv-attribute shortcode as needed to pass information around between Views and their parent context.
Problem: I would like to add a post owner filter to a View of a Repeatable Field Group (RFG). I am building this View in the Blocks editor, but I cannot see any way to add a dynamic filter based on the post being displayed.
Solution: Select the top-level View block using the Block Navigation menu, then you will find a Query Filter configuration panel in the right column of the Block Editor screen. You can add a post owner filter or any other Query Filter here. In an upcoming release of Views, you will be prompted to select this filter during the creation of the View. This improved workflow will help resolve this confusion.
