I'm building a shop with Woocommerce and using WooCommerce Product Category widget. I have set many product categories with subcategories. One of these categories is "Posters" and has several subcategories, like "Star signs", "Travel", "Nature"…
By default Woocommerce only shows the parent categories which is good. If I click a category "posters", I'm redirected to "posters" category archive page and the widget displays all "Posters" children subcategories and it's perfect.
Now, if I click on one of these "Posters" children subcategories, I'm redirected to the respective archive page, but my navigation doesn't show all other "Posters" children subcategories anymore.
The question:
How do I get all parent category and "sibling" subcategories while browsing a subcategory?
Random example of the standard navigation when collapsed:
Phone Cases
Mugs
Pillows
Posters
Shirts
Stickers
Example of navigation when "Posters" has been clicked:
Phone Cases
Mugs
Pillows
Posters
--Star Signs
--Travel
--Nature
--Abstract
--Typography
Shirts
Stickers
When a subcategory is clicked, e.g. "Nature", the navigation returns to look like the first example given, all collapsed. But I want it to stay expanded like in the second example.
Bellow in the screenshot are my settings for Woocommerce Product Category widget:
Any help will be appreciated.
Your settings are correct. The code below is targeting archives category pages only and it will display now all children subcategories in the Woocommerce Product Category widget, for the current subcategory:
add_filter('woocommerce_product_categories_widget_args', 'widget_product_categories_list_args', 10, 1);
function widget_product_categories_list_args( $list_args ) {
global $wp_query;
// Only for category archives pages
if ( is_tax( $list_args['taxonomy'] ) ):
// Get current category
$current_cat = $wp_query->queried_object;
// Get all Included category terms IDs in the widget
$included_ids = explode( ',', $list_args['include'] );
// Get All Childrens Ids from parent term or from current term
if($current_cat->parent != 0 )
$childrens = get_term_children( $current_cat->parent, $list_args['taxonomy'] );
else
$childrens = get_term_children( $current_cat->term_id, $list_args['taxonomy'] );
// Loop through Children term Ids and add them to existing included ones
foreach( $childrens as $child )
$included_ids[] = $child;
// Replace included product category term IDs in the $args array
$list_args['include'] = $included_ids;
endif;
return $list_args;
}
Code goes in function.php file of the active child theme (or active theme).
Tested and works.
I'm trying to get Wordpress to give me a menu item to go to "latest posts." They come up on the frontpage, but once I navigate away, I want a menu item to get back there. It seems so obvious, but several hours later, the best I could do was create a custom menu with a link to "uncategorised" as a workaround. There MUST be a better way! And this way, I get a box saying "Archive of posts filed under the Uncategorized category. " Not wanted!
Create a custom page in your template directory (http://codex.wordpress.org/Pages#Page_Templates) with a custom query (check at http://codex.wordpress.org/Class_Reference/WP_Query, http://codex.wordpress.org/Function_Reference/query_posts or http://codex.wordpress.org/Template_Tags/get_posts).
Create a page in your admin and select the template you created.
Add a link to this page in your menu and you're done.
Maybe this will help: http://www.viper007bond.com/2011/09/20/code-snippet-add-a-link-to-latest-post-to-wordpress-nav-menu/
It's a filter that will 'search and replace' placeholder anchors such as '#latestpost1' with the actual url of the latest post, and thus dynamically modify the menu before it's rendered.
I'm not sure how this is for SEO, but it's a clever solution.
Give all your posts a category name. Use something generic like "News", "Articles" or "Blogs". Then, choose the category with the name you picked from the menu page under categories. Add this category link to your menu. Rename the link whatever you wish - "Blog" - for example. And, viola - all your posts will appear when people click on that link.
Try this plugin: https://de.wordpress.org/plugins/dynamic-latest-post-in-nav-menu/ works really well and code is open sourced here: https://github.com/hijiriworld/dynamic-latest-post-in-nav-menu
simple solution:
I took this guy's code: http://www.viper007bond.com/2011/09/20/code-snippet-add-a-link-to-latest-post-to-wordpress-nav-menu/
Basically what he wrote is for the menu item to link to the latest post, not posts (plural), so I just modified it and it's working:
<?php
if ( ! is_admin() ) {
// Hook in early to modify the menu
// This is before the CSS "selected" classes are calculated
add_filter( 'wp_get_nav_menu_items', 'replace_placeholder_nav_menu_item_with_latest_post', 10, 3 );
}
// Replaces a custom URL placeholder with the URL to the latest post
function replace_placeholder_nav_menu_item_with_latest_post( $items, $menu, $args ) {
// Loop through the menu items looking for placeholder(s)
foreach ( $items as $item ) {
// Is this the placeholder we're looking for?
if (!strpos(($item->url), 'latestpost'))
continue;
// if ( 'latestpost' != $item->url )
// continue;
// Get the latest post
$latestpost = get_posts( array(
'numberposts' => 1,
) );
if ( empty( $latestpost ) )
continue;
// Replace the placeholder with the real URL
$new_link = $item->url;
$new_link = substr($new_link, 0, strlen($new_link) - 12);
$item->url = $new_link;
}
// Return the modified (or maybe unmodified) menu items array
return $items;
}
I'm building a WordPress plugin and I'd like to have an edit-item page that can't be reached via the submenu (because then the item wouldn't be specified).
This resource (http://codex.wordpress.org/Adding_Administration_Menus) shows how to associate an admin page with a function, but not how to do so without adding it as a menu item.
Can this be done?
Thanks!

use add_submenu_page with parent slug = null
I have finally discovered a way to do this that isn't an ugly hack, doesn't require JS to highlight the desired menu item (and submenu item), and works for regular menus registered by plugins (#Josh's answer only works for custom post types).
Essentially, you just need to register your submenu normally, but then hook into the 'submenu_file' filter to deregister it and optionally also set another submenu item to highlight instead.
function so3902760_wp_admin_menu() {
// Register the parent menu.
add_menu_page(
__( 'Parent title', 'textdomain' )
, __( 'Parent', 'textdomain' )
, 'manage_options'
, 'my_parent_slug'
, 'display_my_menu'
);
// Register the hidden submenu.
add_submenu_page(
'my_parent_slug' // Use the parent slug as usual.
, __( 'Page title', 'textdomain' )
, ''
, 'manage_options'
, 'my_hidden_submenu'
, 'display_my_submenu'
);
}
add_action( 'admin_menu', 'so3902760_wp_admin_menu' );
function so3902760_wp_admin_submenu_filter( $submenu_file ) {
global $plugin_page;
$hidden_submenus = array(
'my_hidden_submenu' => true,
);
// Select another submenu item to highlight (optional).
if ( $plugin_page && isset( $hidden_submenus[ $plugin_page ] ) ) {
$submenu_file = 'submenu_to_highlight';
}
// Hide the submenu.
foreach ( $hidden_submenus as $submenu => $unused ) {
remove_submenu_page( 'my_parent_slug', $submenu );
}
return $submenu_file;
}
add_filter( 'submenu_file', 'so3902760_wp_admin_submenu_filter' );
Yes, this can be done (well, technically, it would be more like registering the whole thing and then removing the menu item later), but It would just be easiest (I think) to check for parameters in the $_GET super-global to indicate that the user wishes to edit a specific item.
For example, you could have a page that lists items to edit, and clicking 'edit' only adds the item's ID to the current URL(query-string).
In the function that displays this page, if ID is defined, give them the page to edit that item.
Otherwise, give them the list view. That's how posts, pages, and other custom post types do it.
add_submenu_page with parent slug = null
OR
add_submenu_page with menu title = null
use this code for creating new page without adding in menu
add_action( 'admin_menu', 'register_newpage' );
function register_newpage(){
add_menu_page($appname, $appname, 'administrator','custompage', 'custom');
remove_menu_page('custom');
}
function custom()
{
echo "hai";
}
Note: This solution doesn't automatically set the current menu and submenu item. If you want to highlight a particular menu as current when the hidden page is viewed, see my other answer.
From the answers that come before me, you can see that there are many ways to do this. However, there is another way that I think may be the best.
Loading the page differently based on the value of a $_GET query var is one option, but it may not be what some people are looking for.
The suggestions regarding add_submenu_page() are on the right track, but each of the previous suggestions have problems. Setting $menu_title to null doesn't keep the menu item from being displayed, it just makes it so the link doesn't have any text. The link still takes up some room in the menu though, so it looks funny. Setting the $parent_slug to null doesn't have this problem, but I noticed that the page's HTML title doesn't display the $page_title text.
My solution was to set $parent_slug to a fake menu slug, like 'i_dont_exist'. The menu item won't be displayed, and when viewing the admin screen the page title will be filled out properly.
add_submenu_page(
'_doesnt_exist'
,__( 'Page title', 'textdomain' )
,''
,'manage_options'
,'menu_slug'
,'display_my_menu'
);
Yes. It is very possible to make a page cannot be reach via submenu, or even the main menu in the WP admin panel. See the code snippet below.
function myplugin_render_edit_page() {
// Code contains the UI for edit page.
}
/**
* Manage menu items and pages.
*/
function myplugin_register_admin_page() {
global $_registered_pages;
$menu_slug = plugin_basename('myplugin.php');
$hookname = get_plugin_page_hookname($menu_slug,'');
if (!empty($hookname)) {
add_action($hookname, 'myplugin_render_edit_page');
}
$_registered_pages[$hookname] = true;
}
add_action('admin_menu', 'myplugin_register_admin_page');
Hopefully, this will help.
Create sub menu page and parent slug leave it empty like this:
// Create page were you can add new users.
public function add_create_user_menu() {
add_submenu_page(
'',
'Create User',
'Create User',
'manage_options',
'create-user',
array( $this, 'add_create_user_page' )
);
}
You can access it like this:
Add New
I've tried all of the suggestions here but with various issues associated with each.
The WordPress codex for add_submenu_page now gives the correct answer, which is to use options.php as your parent slug. I tried the trick of using a made up name but that gives permissions errors, equally use of null at various locations either causes the menu text to simply be missing (but still clickable) or for the browser title to go missing.
Using options.php worked and I've not seen any issues as a result of its use.
Using add_submenu_page with a parent of NULL definitely works, however if you want to keep the non-linked page associated with a particular menu (say a custom post type menu), you have to use a variation of #Boopathi's answer:
function my_hidden_submenu_page(){
//add the submenu page the usual way
add_submenu_page('edit.php?post_type=custom-type', 'My Page Title', 'My Page Title', 'manage_options', 'my-page-slug', 'my_page_callback');
//then remove it
remove_submenu_page('edit.php?post_type=custom-type','my-page-slug');
}
add_action('admin_menu', 'my_hidden_submenu_page');
It looks as though the two actions would cancel each other out, however remove_submenu_page does not unregister the callback function; it merely removes the link.
This way when someone is viewing your non-linked page, the correct navigation menu (our custom post type menu in this example) will still show as active.
One of the problems I found with merely adding null as the parent slug for a sub menu item is that if you're currently viewing that specific page the submenu itself won't display (at least it didn't for me (along with the page title not showing).
What I did was add an empty span element inside the menu title and use jquery to traverse the parent elements and hide it.
It seems this need is still valid for nowadays version.
I am using WordPress 5.3.2 and I used the following methods to remove the parent named menu from the submenu.
add_action( 'admin_menu', 'submenus' );
function submenus()
{
global $submenu;
$parent_slug = 'parent_slug_name';
// remove parent named menu from submenu because it is always the first one in the submenu array, so the offset is 0 and remove just 1
array_splice( $submenu[$parent_slug], 0, 1 ); // with reindex
// or unset( $submenu[$parent_slug][0] ); // without reindex
}
Hope it helps others who want to achieve the same goal.
About php array_splice()
this method could be found in the source of WP function remove_submenu_page() which is available since WP 3.1.0
Edit / Added
Apart from submenu, parent menu could also be updated in similar way.
For parent menu, the global variable is $menu.
example for reference:
add_action( 'admin_menu', array( $this, 'modify_menu_title' ) );
function modify_menu_title() {
global $menu;
$page = 'some-page-slug';
$new_menu_title = 'New Title Name';
foreach( $menu as $key => $value ) {
if( $menu[$key][2] === $page ) {
$menu[$key][0] = $new_menu_title;
}
}
}
I find you can do it by reusing the insert id, like so:
add_menu_page( 'User AS Packages', 'User AS', 'manage_options', 'myplugin/editaspackages.php', 'UserASPackages', '', 8);
add_menu_page( 'User ARP Packages', 'User ARP', 'manage_options', 'myplugin/editarppackages.php', 'UserARPPackages', '', 8);
add_menu_page( 'AS Packages', 'AS Packages', 'manage_options', 'myplugin/ars-s2.php', 'ARPPackages', '', 8);
The last 3 using position 8 and the last one overrides the two before so the two before do not appear.
