Did you try: function exclude_category($query) { if ( is_page(‘slug-of-page’) && isset($query) ) { $query->set(‘cat’, ‘-3’); } return $query; } add_filter(‘pre_get_posts’, ‘exclude_category’);
The way you’re appending a foreach loop to a variable is not possible. Try this: $form_fields[“custom4”][“html”] = “<select name=”attachments[{$post->ID}][custom4]” id=’attachments[{$post->ID}][custom4]’>”; foreach ($categories as $category) { $form_fields[“custom4”][“html”] .= ‘<option value=”$category”>’ . $category . ‘</option>’; } $form_fields[“custom4”][“html”] .= “</select>”;

WordPress has a pretty good inbuilt bulk editing system. Just select all the products/post for each category and select bulk edit from the menu where you’d normally see more to trash.
I would use WP_Query for this, as I am more comfortable with it. There are two solutions to this that occur to me. If you’re not heartset on the categories, then WP_Query has good support for date parameters, to include a year parameter. A query by year would look something like this: $wpse176213_query = new … Read more
List post categories that link to a page showing those posts
One way to do this would be to create a custom widget which displays categories using wp_list_categories(). Then exclude any categories you don’t want displayed using the exclude option of wp_list_categories(): http://codex.wordpress.org/Template_Tags/wp_list_categories#Include_or_Exclude_Categories. This example below creates a custom categories widget in Appearance / Widgets. This code can be added to functions.php or used in a … Read more
First you would need to check if the category has children, if it does then we can show a few things. Below is a helpful function to check just that. function category_has_children( $term_id = 0, $post_type=”post”, $taxonomy = ‘category’ ) { $children = get_categories( array( ‘child_of’ => $term_id, ‘type’ => $post_type, ‘taxonomy’ => $taxonomy ) … Read more
It might be not your case but if behind the scene permalink settings have been switched from default one, then the request: ?category_name=slug1+slug2 is rewritten to /category/slug1/ or /category/slug2/ so only the posts from one category are shown.
