WordPress Custom Hook For Filtering Post Queries By Category
This code snippet filters WordPress post queries based on custom conditions, specifically by category, using the 'pre_get_posts' action hook. It is useful when you need to modify the post query without altering the core WordPress code, such as displaying posts from a specific category. The hook checks if the query is the main query and not a preview before applying the filter. To use this snippet, simply attach the function to the 'pre_get_posts' action hook and replace 'my-category' with your desired category slug.
