我试图在管理菜单项下显示自定义分类法,这只是一个页面,即http://example.com/wp-admin/admin.php?page=bla。
根据register_taxonomy下show_in_menu
的WordPress Dev. page,它说:
'some string' -如果现有的顶级页面,如'tools.php'或'edit.php?Post_type =page',则post类型将被放置为该页面的子菜单。
这是否意味着分类法只能在这些分类下显示?
PHP<?php
// hook into the init action and call create_book_taxonomies when it fires
add_action( 'init', 'create_book_taxonomies', 0 );
// create two taxonomies, genres and writers for the post type "book"
function create_book_taxonomies() {
// Add new taxonomy, make it hierarchical (like categories)
$labels = array(
'name' => _x( 'Genres', 'taxonomy general name' ),
'singular_name' => _x( 'Genre', 'taxonomy singular name' ),
'search_items' => __( 'Search Genres' ),
'all_items' => __( 'All Genres' ),
'parent_item' => __( 'Parent Genre' ),
'parent_item_colon' => __( 'Parent Genre:' ),
'edit_item' => __( 'Edit Genre' ),
'update_item' => __( 'Update Genre' ),
'add_new_item' => __( 'Add New Genre' ),
'new_item_name' => __( 'New Genre Name' ),
'menu_name' => __( 'Genre' ),
);
$args = array(
'hierarchical' => true,
'labels' => $labels,
'show_ui' => true,
'show_in_menu' => 'bla', // not working | tried admin.php?page=bla as well, also not working
'show_admin_column' => true,
'query_var' => true,
'rewrite' => array( 'slug' => 'genre' ),
);
register_taxonomy( 'genre', array( 'book' ), $args );
}
我已经找到了解决这个问题的方法,代码如下:
add_action( 'admin_menu', 'shmeh_menu' );
add_action( 'parent_file', 'menu_highlight' );
function shmeh_menu() {
add_submenu_page( 'bla', 'Shmeh', 'Shmeh', 'manage_options', 'edit-tags.php?taxonomy=shmeh');
}
function menu_highlight( $parent_file ) {
global $current_screen;
$taxonomy = $current_screen->taxonomy;
if ( $taxonomy == 'shmeh' ) {
$parent_file = 'bla';
}
return $parent_file;
}
在您的分类法注册:
show_in_menu => true
然后需要添加一个子菜单页:
$parent_slug = 'slug_for_parent_menu';
$page_title = 'Submenu Page Title';
$menu_title = 'Submenu Page Title';
$capability = 'manage_options';
$menu_slug = 'edit-tags.php?taxonomy=bla&post_type=custom_post_type_name';
$function = null;
$position = null;
add_submenu_page($parent_slug, $page_title, $menu_title, $capability, $menu_slug, $function, $position);
最后:
add_filter('parent_file', 'menu_highlight');
function menu_highlight($parent_file) {
global $plugin_page, $submenu_file, $post_type, $taxonomy;
if ('custom_post_type_name' == $post_type) {
if ($taxonomy == 'bla') {
$plugin_page = 'edit-tags.php?taxonomy=bla&post_type= custom_post_type_name'; // the submenu slug
$submenu_file = 'edit-tags.php?taxonomy=bla&post_type= custom_post_type_name'; // the submenu slug
}
}
return $parent_file;
}
希望我把这些都写对了。在分类法检查中嵌套其他if,并为其他帖子类型添加相同的内容。
假设我们的分类标签是vendor
,我们想把它放在下面的父菜单是my_menu
。
要授予访问权限,使用默认的manage_categories
能力。这需要与在$args
参数中传递的capabilities
数组中提供给register_taxonomy
函数的值相匹配。
add_action('admin_menu', function (): void {
add_submenu_page(
'my_menu', // parent_slug
'Vendors', // page_title
'Vendors', // menu_title
'manage_categories', // capability
'edit-tags.php?taxonomy=vendor' // menu_slug
);
});
add_action('parent_file', function (string $parent_file): string {
global $current_screen;
if ($current_screen->taxonomy === 'vendors') {
return 'my_menu';
}
return $parent_file;
});
