Community Q&A
How do I use WP_Query in WordPress?
WP_Query is a class used to fetch posts from the database. You define an array of arguments and pass it to a new instance of the class to run your custom loop.
Why is my custom post type not showing in the Query Loop block?
This is usually because the ‘show_in_rest’ parameter is set to false in your register_post_type function. Gutenberg blocks require the REST API to populate data.
How can I optimize WP_Query for performance?
Avoid complex queries that hammer the database. Use specific arguments, limit the number of posts, and consider using search plugins like Relevanssi for heavy search tasks.
