Members plugin: Hide posts if user doesn’t have access

Hi Fredric,

You may exclude posts from the “Advanced Sidebar – Categories” menus by adding the following custom filters to your active theme’s functions.php file.

class Members_Restriced_Display_Posts_Walker extends Advanced_Sidebar_Menu\Walkers\Posts { public function get_children( \WP_Term $term, $depth, $args, $id ) { $children = parent::get_children( $term, $depth, $args, $id ); return \array_filter( $children, function( $post ) { return members_can_user_view_post( get_current_user_id(), $post->ID ); } ); } } add_filter( 'advanced-sidebar-menu/menus/category/get-list-categories-args', function( array $args, string $level, Category $menu ): array { $args['walker'] = new Members_Restriced_Display_Posts_Walker( $menu->get_widget_instance(), $level ); return $args; }, 1_000, 4 );

Have a great day!

P.S. I’ve added a new advanced-sidebar-menu-pro/walker/display-posts/children filter to the Advanced Sidebar Menu PRO plugin which will simplify this type of adjustment in the future. It will be available in the next version (not yet scheduled).

Hi Fredric,

I see what happened. The Category class is not in use.

Here is a version which does not require it.

class Members_Restriced_Display_Posts_Walker extends Advanced_Sidebar_Menu\Walkers\Posts { public function get_children( \WP_Term $term, $depth, $args, $id ) { $children = parent::get_children( $term, $depth, $args, $id ); return \array_filter( $children, function( $post ) { return members_can_user_view_post( get_current_user_id(), $post->ID ); } ); } } add_filter( 'advanced-sidebar-menu/menus/category/get-list-categories-args', function( array $args, string $level, $menu ): array { $args['walker'] = new Members_Restriced_Display_Posts_Walker( $menu->get_widget_instance(), $level ); return $args; }, 1_000, 4 );

Hi Fredric,

I have updated the above filter to also exclude categories which do not have any posts to display. It is a bit heavy to check for available posts during the display of each category but I did what I could to reuse the results and reduce the number of queries.

I’m guessing a bit on context so here is what the filter will do:

1. Exclude any posts from the menu.
2. Exclude any categories from the menu which don’t have
   1. Child categories. (or)
   2. Posts to display.

use Advanced_Sidebar_Menu\Menus\Category; class Members_Restriced_Display_Posts_Walker extends Advanced_Sidebar_Menu\Walkers\Posts { public Category $menu; public function start_el( &$output, $term, $depth = 0, $args = [], $id = 0 ) { $this->children[ $term->term_id ] = $this->get_children( $term, $depth, $args, $id ); if ( \count( $this->children[ $term->term_id ] ) > 0 || $this->menu->has_children( $term ) ) { parent::start_el( $output, $term, $depth, $args, $id ); } } /** * @param \WP_Term $data_object */ public function end_el( &$output, $data_object, $depth = 0, $args = [] ) { if ( ( isset( $this->children[ $data_object->term_id ] ) && \count( $this->children[ $data_object->term_id ] ) > 0 ) || $this->menu->has_children( $data_object ) ) { parent::end_el( $output, $data_object, $depth, $args ); } } public function get_children( \WP_Term $term, $depth, $args, $id ) { $children = parent::get_children( $term, $depth, $args, $id ); return \array_filter( $children, function( $post ) { return members_can_user_view_post( get_current_user_id(), $post->ID ); } ); } } add_filter( 'advanced-sidebar-menu/menus/category/get-list-categories-args', function( array $args, string $level, Category $menu ): array { $args['walker'] = new Members_Restriced_Display_Posts_Walker( $menu->get_widget_instance(), $level ); $args['walker']->menu = $menu; return $args; }, 1_000, 4 );

Have a great day!
