如何在WordPress自定义帖子类型中按类别显示帖子 _WordPress开发

朋友你好我被困在代码中。我在其中创建了一个自定义帖子类型, 并在页面模板中也将其称为类别。我使用以下代码显示帖子类型的类别。

< ?php $args = array( 'type'=> 'post', 'child_of'=> 0, 'parent'=> '', 'orderby'=> 'name', 'order'=> 'ASC', 'hide_empty'=> 1, 'hierarchical'=> 1, 'exclude'=> '', 'include'=> '', 'number'=> '', 'taxonomy'=> 'readings_post-category', 'pad_counts'=> false ); $categories = get_categories($args); echo '< ul> '; foreach ($categories as $category) { $url = get_term_link($category); ?> < li> < a href="http://www.srcmini.com/< ?php echo $url; ?>"> < ?php echo $category-> name; ?> < /a> < /li> < ?php }echo '< /ul> '; ?>

【如何在WordPress自定义帖子类型中按类别显示帖子】现在, 当我单击某个类别时, 它会显示404错误页面而不显示我的帖子。请帮助我。我用以下代码创建了一个自定义帖子类型。

/* readings Post Type */ if ( !function_exists('readings_category_register') ) { function readings_category_register() { $readings_permalinks = get_option( 'readings_permalinks' ); $args = array( "label"=> __('Topics'), "singular_label"=> __('Topic'), 'public'=> true, 'hierarchical'=> true, 'show_ui'=> true, 'show_in_nav_menus'=> false, 'args'=> array( 'orderby' => 'term_order' ), 'rewrite'=> array( 'slug'=> empty( $readings_permalinks['category_base'] ) ? __( 'readings-category' ) : __( $readings_permalinks['category_base']), 'with_front' => false ), 'query_var'=> true ); register_taxonomy( 'readings-category', 'readings', $args ); } add_action( 'init', 'readings_category_register' ); } /* readings POST TYPE ================================================== */ if ( !function_exists('readings_register') ) { function readings_register() { $readings_permalinks = get_option( 'readings_permalinks' ); $readings_permalink= empty( $readings_permalinks['readings_base'] ) ? __( 'readings' ) : __( $readings_permalinks['readings_base']); $labels = array( 'name' => __('readings'), 'singular_name' => __('readings'), 'add_new' => __('Add New readings'), 'add_new_item' => __('Add New readings'), 'edit_item' => __('Edit readings'), 'new_item' => __('New readings'), 'view_item' => __('View readingss'), 'search_items' => __('Search readings'), 'not_found' => __('No readingss have been added yet'), 'not_found_in_trash' => __('Nothing found in Trash'), 'parent_item_colon' => '' ); $args = array( 'labels'=> $labels, 'public'=> true, 'show_ui'=> true, 'show_in_menu'=> true, 'show_in_nav_menus' => true, 'menu_icon'=> 'dashicons-groups', 'rewrite'=> $readings_permalink != "readings" ? array( 'slug'=> untrailingslashit( $readings_permalink ), 'with_front' => false, 'feeds'=> true ) : false, // 'supports' => array('title', 'editor'), 'show_in_rest' => true, 'supports' => array('title', 'editor', 'author', 'thumbnail', 'excerpt', 'comments', 'categories'), //"taxonomies" => [ "readings-category" ], 'has_archive' => true, 'taxonomies' => array('readings-category') ); register_post_type( 'readings', $args ); } add_action( 'init', 'readings_register' ); } /* readings POST TYPE COLUMNS ================================================== */ if ( !function_exists('readings_edit_columns') ) { function readings_edit_columns($columns){ $columns = array( "cb" => "< input type=\"checkbox\" /> ", "title" => __("readings Name"), "description" => __("readings Description"), "readings-category" => __("readings Category") ); return $columns; } add_filter("manage_edit-readings_columns", "readings_edit_columns"); }

#1尝试这个

$args = array( 'posts_per_page' => -1, 'post_type' => 'here write post name', 'orderby' => 'date', 'order' => 'DESC', 'category_name' => 'here write category name' ); $loop = new WP_Query( $args ); < ?php while ( $loop-> have_posts() ) : $loop-> the_post(); ?> ... < ?php endwhile; ?>
