Community Q&A
What is WP_Query in WordPress?
WP_Query is a powerful PHP class that allows developers to fetch posts, pages, and custom post types from the WordPress database based on specific criteria.
How do I optimize slow WP_Query calls?
To optimize, use specific arguments to limit results, avoid unnecessary meta queries, and implement object caching to reduce database load.
Should I use WP_Query or get_posts?
Use get_posts for simple retrieval of post arrays, but use WP_Query when you need full control over the main loop, pagination, and complex filtering.
