There’s not an easy way to modify the export query that runs under /wp-admin/export.php. It doesn’t use the WP_Query or the get_posts() wrapper, instead it currently uses this query: $post_ids = $wpdb->get_col( “SELECT ID FROM {$wpdb->posts} $join WHERE $where” ); without explicit filters to it, though it’s possible to filter few settings through the export_args … Read more

A note about the following code: Most parameters might be added to the query like meta_query, category. wp_create_category(), will create a category once. wp_set_post_terms(), only work with native post types, will … Read more

Note that: the filter post_row_actions takes two arguments, the second one being $post, so the global is not necessary. instead of using id as query argument, it’s best practice to use custom names, in this case update_id. I didn’t know … Read more
If you want do what the TablePress author recommended, you’d need first to create a custom page (or post category) template – see Codex for Page_Templates – I wouldn’t explained it better then there. 🙂 There you’d need to create a custom WP_Query, or get_posts() / get_pages() query to get the list of posts or … Read more
Firts / last post make sense if we have an order to refer to. get_next_post() function use post date to decide which post is the next.

Example formula for an offset with pagination: ‘posts_per_page’ => $posts_per_page, ‘offset’ => ( $paged – 1 ) * $posts_per_page + $offset_per_page, Example: Then for $posts_per_page as 4 and $offset_per_page as 5 we get the post … Read more
