Showing posts between a certain date range

由 依然范特西╮ 提交于 2019-12-23 12:28:27
问题 Trying to display my custom post types for specific date ranges. I want to show posts only within a certain month. I know I need to hook into the posts_where filter, but I can not figure out how to pass arguments to this function, as I need to pass the date range. I have seen plenty of examples of how to alter the WHERE clause to take a date range, but only when static. I need to do the following: add_filter('posts_where', 'my_custom_where', '', '04/2011'); //pass my date to the filter

Difference between add_filter versus add_action

由 泪湿孤枕 提交于 2019-12-10 13:26:56
问题 I was looking over my functions.php and wondering why CODE A uses add_action while CODE B uses add_filter ? The main goal of CODE A is to both include and exclude specific categories.

CODE A: Display specific category (called "featured") for homepage, instead of "the most recent posts" function featured_category( $query ) { if ( $query->is_home() && $query->is_main
