我在设置永久链接结构时遇到了一些麻烦：
www.mysite.com/some-constant-term/%custom-tax-term-slug%/%custom-post-name%/
我在插件中这样做，我正在设置我的CPT：
add_action('init', 'message_board_cpt');
function message_board_cpt()
{
$cap_type = 'post';
$plural = 'Message Board Subjects';
$single = 'Message Board Subject';
$cpt_name = 'mmp-mb-subject';
$opts['can_export'] = TRUE;
$opts['capability_type'] = $cap_type;
$opts['description'] = 'These posts will serve as the subjects for the message board.';
$opts['exclude_from_search'] = TRUE;
$opts['has_archive'] = FALSE;
$opts['hierarchical'] = FALSE;
$opts['map_meta_cap'] = TRUE;
$opts['menu_icon'] = 'dashicons-exerpt-view';
$opts['menu_position'] = 25;
$opts['public'] = TRUE;
$opts['publicly_querable'] = FALSE;
$opts['query_var'] = FALSE;
$opts['register_meta_box_cb'] = '';
$opts['rewrite'] = true;
$opts['show_in_admin_bar'] = TRUE;
$opts['show_in_menu'] = TRUE;
$opts['show_in_nav_menu'] = TRUE;
$opts['labels']['add_new'] = esc_html__( "Add New {$single}", 'wisdom' );
$opts['labels']['add_new_item'] = esc_html__( "Add New {$single}", 'wisdom' );
$opts['labels']['all_items'] = esc_html__( $plural, 'wisdom' );
$opts['labels']['edit_item'] = esc_html__( "Edit {$single}" , 'wisdom' );
$opts['labels']['menu_name'] = esc_html__( $plural, 'wisdom' );
$opts['labels']['name'] = esc_html__( $plural, 'wisdom' );
$opts['labels']['name_admin_bar'] = esc_html__( $single, 'wisdom' );
$opts['labels']['new_item'] = esc_html__( "New {$single}", 'wisdom' );
$opts['labels']['not_found'] = esc_html__( "No {$plural} Found", 'wisdom' );
$opts['labels']['not_found_in_trash'] = esc_html__( "No {$plural} Found in Trash", 'wisdom' );
$opts['labels']['parent_item_colon'] = esc_html__( "Parent {$plural} :", 'wisdom' );
$opts['labels']['search_items'] = esc_html__( "Search {$plural}", 'wisdom' );
$opts['labels']['singular_name'] = esc_html__( $single, 'wisdom' );
$opts['labels']['view_item'] = esc_html__( "View {$single}", 'wisdom' );
register_post_type( strtolower( $cpt_name ), $opts );
flush_rewrite_rules();
}
设置我的自定义分类：
add_action('init', 'message_board_tax');
function message_board_tax()
{
$labels = array(
'name' => __( 'Message Board Categories', 'mmp-mb-subject' ),
'singular_name' => __( 'Message Board Category', 'mmp-mb-subject' ),
'menu_name' => __( 'Message Board Categories', 'mmp-mb-subject' ),
'edit_item' => __( 'Edit Message Board Category', 'mmp-mb-subject' ),
'update_item' => __( 'Update Message Board Category', 'mmp-mb-subject' ),
'add_new_item' => __( 'Add New Message Board Category', 'mmp-mb-subject' ),
'new_item_name' => __( 'New Message Board Category Name', 'mmp-mb-subject' ),
'parent_item' => __( 'Parent Message Board Category', 'mmp-mb-subject' ),
'parent_item_colon' => __( 'Parent Message Board Category:', 'mmp-mb-subject' ),
'all_items' => __( 'All Message Board Categories', 'mmp-mb-subject' ),
'search_items' => __( 'Search Message Board Categories', 'mmp-mb-subject' ),
'popular_items' => __( 'Popular Message Board Categories', 'mmp-mb-subject' ),
'separate_items_with_commas' => __( 'Separate message board categories with commas', 'mmp-mb-subject' ),
'add_or_remove_items' => __( 'Add or remove message board categories', 'mmp-mb-subject' ),
'choose_from_most_used' => __( 'Choose from the most used message board categories', 'mmp-mb-subject' ),
'not_found' => __( 'No message board categories found.', 'mmp-mb-subject' ),
);
$args = array(
'labels' => $labels,
'public' => true,
'show_in_nav_menus' => true,
'show_ui' => true,
'show_tagcloud' => true,
'hierarchical' => true,
'rewrite' => array( 'slug' => 'cpt-constant/%mmp-message-board-tax%' ),
// 'rewrite' => true,
// 'rewrite' => false,
'show_admin_column' => true,
// 'query_var' => true,
);
$args = apply_filters( 'mb_subject_category_args', $args );
register_taxonomy('mmp-message-board-tax', 'mmp-mb-subject', $args);
flush_rewrite_rules();
}
然后我创建一个分类法重写规则，如下所示：
add_action('generate_rewrite_rules', 'generate_taxonomy_rewrite_rules');
generate_taxonomy_rewrite_rules($wp_rewrite)
{
$rules = array();
$post_types = get_post_types( array( 'name' => 'mmp-mb-subject', 'public' => true, '_builtin' => false ), 'objects' );
$taxonomies = get_taxonomies( array( 'name' => 'mmp-message-board-tax', 'public' => true, '_builtin' => false ), 'objects' );
foreach ( $post_types as $post_type ) {
$post_type_name = $post_type->name; // 'developer'
$post_type_slug = $post_type->rewrite['slug']; // 'developers'
foreach ( $taxonomies as $taxonomy ) {
if ( $taxonomy->object_type[0] == $post_type_name ) {
$terms = get_categories( array( 'type' => $post_type_name, 'taxonomy' => $taxonomy->name, 'hide_empty' => 0 ) );
foreach ( $terms as $term ) {
$rules[$post_type_slug . '/' . $term->slug . '/?$'] = 'index.php?' . $term->taxonomy . '=' . $term->slug;
}
}
}
}
$wp_rewrite->rules = $rules + $wp_rewrite->rules;
// $rules = array();
// $terms = get_terms( array(
// 'taxonomy' => 'resource_type',
// 'hide_empty' => false,
// ) );
//
// $post_type = 'mmp-mb-subject';
// foreach ($terms as $term) {
//
// $rules['cpt-constant/' . $term->slug . '/([^/]*)$'] = 'index.php?post_type=' . $post_type. '=$matches[1]&name=$matches[1]';
//
// }
// // merge with global rules
// $wp_rewrite->rules = $rules + $wp_rewrite->rules;
}
最后我为我的cpt设置了一个重写规则：
add_action('post_type_link', 'change_message_board_cpt_link',10,2);
change_message_board_cpt_link( $permalink, $post ) {
if( $post->post_type == 'mmp-mb-subject' ) {
$resource_terms = get_the_terms( $post, 'mmp-message-board-tax' );
$term_slug = '';
if( ! empty( $resource_terms ) ) {
foreach ( $resource_terms as $term ) {
// The featured resource will have another category which is the main one
// if( $term->slug == 'featured' ) {
// continue;
// }
$term_slug = $term->slug;
break;
}
}
$permalink = get_home_url() ."/cpt-constant/" . $term_slug . '/' . $post->post_name;
}
return $permalink;
}
我能够进入我的分类页面（所有不同术语的列表），但当我尝试去个别帖子时，我得到了404？
