在WordPress中仅显示自定义帖子类型的固定链接中的特定类别
我试图在Wordpress Devlopment网络中提出这个问题并没有取得成功，我试图在固定链接中为自定义后期类型显示仅3个特定类别。
现在，永久链接结构（即我使用的主题给出的结构，以及通过儿童主题进行修改的结构）如下所示：
www.myfoodblog.com/recipes/the-post-title/
^ ^ ^
root custom-post-type title
有些帖子是我想要显示在restaurant ， users和admin这样的固定链接中的3种类别
www.myfoodblog.com/recipes/restaurant/the-post-title/
www.myfoodblog.com/recipes/users/the-post-title/
www.myfoodblog.com/recipes/admin/the-post-title/
留下不属于这些类别的帖子的原始结构。
我试过使用这个插件，但它会显示所有帖子的自定义帖子类型分类。
我也试着按照这个问题提供的说明，但它不起作用，永久链接结构没有改变。
任何意见非常感谢。
您必须使用post_type_link并添加rewrite rule
function recipes_post_link( $post_link, $id = 0 ){
$post = get_post( $id );
if ( is_object( $post ) ){
$terms = get_the_terms( $post->ID, 'recipe-category' );
foreach($terms as $term) {
if( $term->slug == 'restaurants' || $term->slug == 'users'){
return str_replace( site_url()."/recipes" , site_url()."/recipes/".$term->slug , $post_link );
}
}
}
return $post_link;
}
add_filter( 'post_type_link', 'recipes_post_link', 1, 3 );
function custom_rewrite_basic() {
add_rewrite_rule('^recipes/(.+)/(.+)', 'index.php?recipe=$matches[2]', 'top');
}
add_action('init', 'custom_rewrite_basic');
创建帖子类型
add_action( 'init', 'codex_recipes_init' );
/**
* Register a recipes post type.
*
* @link http://codex.wordpress.org/Function_Reference/register_post_type
*/
function codex_recipes_init() {
$labels = array(
'name' => _x( 'Recipes', 'post type general name', 'your-plugin-textdomain' ),
'singular_name' => _x( 'Recipe', 'post type singular name', 'your-plugin-textdomain' ),
'menu_name' => _x( 'Recipes', 'admin menu', 'your-plugin-textdomain' ),
'name_admin_bar' => _x( 'Recipe', 'add new on admin bar', 'your-plugin-textdomain' ),
'add_new' => _x( 'Add New', 'recipe', 'your-plugin-textdomain' ),
'add_new_item' => __( 'Add New Recipe', 'your-plugin-textdomain' ),
'new_item' => __( 'New Recipe', 'your-plugin-textdomain' ),
'edit_item' => __( 'Edit Recipe', 'your-plugin-textdomain' ),
'view_item' => __( 'View Recipe', 'your-plugin-textdomain' ),
'all_items' => __( 'All Recipes', 'your-plugin-textdomain' ),
'search_items' => __( 'Search Recipes', 'your-plugin-textdomain' ),
'parent_item_colon' => __( 'Parent Recipes:', 'your-plugin-textdomain' ),
'not_found' => __( 'No recipes found.', 'your-plugin-textdomain' ),
'not_found_in_trash' => __( 'No recipes found in Trash.', 'your-plugin-textdomain' )
);
$args = array(
'labels' => $labels,
'description' => __( 'Description.', 'your-plugin-textdomain' ),
'public' => true,
'publicly_queryable' => true,
'show_ui' => true,
'show_in_menu' => true,
'query_var' => true,
'rewrite' => array( 'slug' => 'recipes/%type%' ),
'capability_type' => 'post',
'has_archive' => 'recipes',
'hierarchical' => false,
'menu_position' => null,
'supports' => array( 'title', 'editor', 'author', 'thumbnail', 'excerpt', 'comments' )
);
register_post_type( 'recipes', $args );
}
重要的是：看重写规则： 'rewrite'=> array( 'slug' => 'recipes/%type%' ),
创建自定义分类
// hook into the init action and call create_recipes_taxonomies when it fires
add_action( 'init', 'create_recipes_taxonomies', 0 );
function create_recipes_taxonomies() {
// Add new taxonomy, NOT hierarchical (like tags)
$labels = array(
'name' => _x( 'Type', 'taxonomy general name', 'textdomain' ),
'singular_name' => _x( 'Type', 'taxonomy singular name', 'textdomain' ),
'search_items' => __( 'Search Types', 'textdomain' ),
'popular_items' => __( 'Popular Types', 'textdomain' ),
'all_items' => __( 'All Types', 'textdomain' ),
'parent_item' => null,
'parent_item_colon' => null,
'edit_item' => __( 'Edit Type', 'textdomain' ),
'update_item' => __( 'Update Type', 'textdomain' ),
'add_new_item' => __( 'Add New Type', 'textdomain' ),
'new_item_name' => __( 'New Type Name', 'textdomain' ),
'separate_items_with_commas' => __( 'Separate types with commas', 'textdomain' ),
'add_or_remove_items' => __( 'Add or remove types', 'textdomain' ),
'choose_from_most_used' => __( 'Choose from the most used types', 'textdomain' ),
'not_found' => __( 'No types found.', 'textdomain' ),
'menu_name' => __( 'Types', 'textdomain' ),
);
$args = array(
'hierarchical' => true,
'labels' => $labels,
'show_ui' => true,
'show_admin_column' => true,
'update_count_callback' => '_update_post_term_count',
'query_var' => true,
'rewrite' => array( 'slug' => 'type' ),
);
register_taxonomy( 'type', 'recipes', $args );
}
添加过滤器帖子类型链接
function recipes_post_link( $post_link, $id = 0 ){
$post = get_post( $id );
if ( is_object( $post ) ){
$terms = wp_get_object_terms( $post->ID, 'type' );
if( $terms ){
return str_replace( '%type%' , $terms[0]->slug , $post_link );
}
}
return $post_link;
}
add_filter( 'post_type_link', 'recipes_post_link', 1, 3 );
重要提示：毕竟转到固定链接选项并重置它。
