In Wordpress, i'd like to automatically add categories from custom post types in a submenu item, with respecting the hierarchy.
This is how my menu will look like:
Projects
Categories
Category 1
Category 2
Subcategory1
Subcategory2
Category 3
....
Other Sub item
ItemX
ItemY
Any idea on how to automatically add all categories in the menu, under "Categories" item?
(It's a menu created in Appearance > Menus)
I guess i might use wp_list_categories() but I have no idea where to place this...
Thanks !
Try this filter
It's a little hacky but i managed to add some stuff into my menus from here
WP nav menu itmes
function wp_nav_menu_items( $items, $args ) {
if ( "primary" == $args->theme_location ) { //check what menu it is
//Do Stuff here
}
return $itmes;
}
add_filter( wp_nav_menu_items, wp_nav_menu_items );
Am trying to get 3 level top-main menu where in sub menu (child page) of particular parent page should not be visible. I should be like :
Product
Product 1
Product 1 A
Product 1 B
Product 2
Product 2 A
Product 2 B
Product 3
NO SUB SUB MENU
I tried child_of - but no luck.
Thanks,

As per our comment conversation, it would not be robust to rely on arbitrarily generated numbers in id/class attributes on your menu elements. But if you could control how your menu items are attributed, then you can control their style reliably.
I believe the best practice way to handle custom menus is to create a "nav walker", which allows you to control which items are emitted to HTML (and how they're emitted). This would give you the choice of either not rendering the particular menu item(s) you want to avoid, or rendering them with id/class hooks allowing your to style them out.
This wp_nav_menu() tute describes the process of setting up a custom wp_nav_menu(), and importantly covers the need to add a custom Walker_Nav_Menu class. This is described in detail in this Understanding the Walker class tute.
I've hacked up a very basic way to do what you require, based on the page title of the parent item. This basically "tricks" the Walker_Nav_Menu into thinking it has exceeded its allowed traversal depth and hence not following that tree branch, in the instance where your ignored menu node is encountered. Add this to your functions.php file:
class Selective_Walker extends Walker_Nav_Menu {
function display_element( $element, &$children_elements, $max_depth, $depth=0, $args, &$output ) {
if (in_array($element->title, array("Product 3"))) // Add any additional items as req'd to this array
$depth = $max_depth + 1;
parent::display_element( $element, &$children_elements, $max_depth, $depth, $args, &$output );
}
}
And then, wherever your theme adds the nav menu (probably header.php), you need to add the walker parameter to the wp_nav_menu() call (in addition to whatever other parameters you're already using), passing it an instance of your new walker class:
<?php wp_nav_menu( array('walker' => new Selective_Walker(), 'theme_location' => 'primary', 'depth' => 3 ) ); ?>
You can customize wordpress menu in your own requirement if you have PHP knowledge.I have Build a function that give parent menu and its child menu in an array format and you can customize your wordpress menu up to any level you want.
Here is the solution
I want that in wp-admin will be only Posts, Pages and Settings, it's possible to remove al remaining Media, Plugins, Users, Tools etc.
This function remove only from dashboard remove_menu_page( 'upload.php' );
Remove that menus from $restricted, that you want to prevent.
function remove_menus () {
global $menu;
$restricted = array(__('Dashboard'), __('Posts'), __('Media'), __('Links'), __('Pages'), __('Appearance'), __('Tools'), __('Users'), __('Settings'), __('Comments'), __('Plugins'));
end ($menu);
while (prev($menu)){
$value = explode(' ',$menu[key($menu)][0]);
if(in_array($value[0] != NULL?$value[0]:"" , $restricted)){unset($menu[key($menu)]);}
}
}

Since WordPress 3.1 you can better use remove_menu_page()
add_action( 'admin_menu', 'prefix_remove_menu_pages' );
function prefix_remove_menu_pages() {
remove_menu_page('edit-comments.php');
remove_menu_page('upload.php');
remove_menu_page('tools.php');
// Remove any item you want
}
}
from the docs:
Please be aware that remove_menu_pages would not prevent a user from accessing
these screens directly. Removing a menu does not replace the need to
filter a user's permissions as appropriate.
And for submenu items:
To remove submenu items in the admin, use remove_submenu_page. Using
remove_menu_page() will not work for submenu 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!
Best solution here http://wordpress.org/support/topic/add-backend-page-without-menu-item
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] = $new_menu_title;
}
}
}
I find you can do it by reusing the insert id, like so:
add_menu_page( 'User AS Packages', 'User AS', 'manage_options', 'myplugin/editaspackages.php', 'UserASPackages', '', 8);
add_menu_page( 'User ARP Packages', 'User ARP', 'manage_options', 'myplugin/editarppackages.php', 'UserARPPackages', '', 8);
add_menu_page( 'AS Packages', 'AS Packages', 'manage_options', 'myplugin/ars-s2.php', 'ARPPackages', '', 8);
The last 3 using position 8 and the last one overrides the two before so the two before do not appear.
I want to override the theming of only one (custom) menu. I can do this with phptemplate_menu_tree() but - of course - it overrides the rendering of all menus.
I've tried returning FALSE (an obvious technique IMO) if the menu is not the specific one I want to override - but this doesn't cause the overridden theme function to be called.
My only alternative (when the menu is anything other than the specific one) is to call the overridden function from within phptemplate_menu_tree() - but this seems to defeat the whole point of the override system, since the default rendering function will be hard-coded therein.
I hope the explanation is clear, and any help is greatly appreciated - tks.
UPDATE
For the sake of future reference, I'll explain how I solved this.
First off, the menu rendering starts with this function in menu.module:
function menu_block($op = 'list', $delta = 0) {
$menus = menu_get_menus();
// The Navigation menu is handled by the user module.
unset($menus['navigation']);
if ($op == 'list') {
$blocks = array();
foreach ($menus as $name => $title) {
// Default "Navigation" block is handled by user.module.
$blocks[$name]['info'] = check_plain($title);
// Menu blocks can't be cached because each menu item can have
// a custom access callback. menu.inc manages its own caching.
$blocks[$name]['cache'] = BLOCK_NO_CACHE;
}
return $blocks;
}
else if ($op == 'view') {
$data['subject'] = check_plain($menus[$delta]);
$data['content'] = menu_tree($delta);
return $data;
}
}
If you only want to override how individual item (links) are rendered then you can use the theme system (there are loads of references on how do this) - but if you want complete control on how the entire menu tree is rendered (for example, wrapping the output in nested DIVs so it can be centred on the page) then there is no way to override menu_block().
Therefore, I removed the menu I wanted to render differently from the administer blocks page (site building->blocks) and rendered the menu directly in my page.tpl.php using code something like this: (angle brackets removed)
$m = menu_tree_page_data('my-menu-id');
$o = "DIV";
foreach($m as $k => $v){
$o .= "SPAN {$v['link']['title']} /SPAN";
}
$o .= "/DIV";
echo $o;
I hope this helps.
I've had mixed success doing template.php menu overrides to force CSS classes and ids or HTML into the output.
You could make use of Block Theme when enabling the menu as a block, but I've never tried it.
http://drupal.org/project/blocktheme
If you want to tackle the template way, here are the zen menu override funcitons...
function zen_menu_item_link($link) {
if (empty($link['localized_options'])) {
$link['localized_options'] = array();
}
// If an item is a LOCAL TASK, render it as a tab
if ($link['type'] & MENU_IS_LOCAL_TASK) {
$link['title'] = '<span class="tab">' . check_plain($link['title']) . '</span>';
$link['localized_options']['html'] = TRUE;
}
return l($link['title'], $link['href'], $link['localized_options']);
}
function zen_menu_local_tasks() {
$output = '';
if ($primary = menu_primary_local_tasks()) {
$output .= '<ul class="tabs primary clear-block">' . $primary . '</ul>';
}
if ($secondary = menu_secondary_local_tasks()) {
$output .= '<ul class="tabs secondary clear-block">' . $secondary . '</ul>';
}
return $output;
}
You could use sections module, or look at how it switches theme for certain menu-items.
what I did was register a new theme function in my template.php called primary_links (because I wanted to only customize this menu in certain way) created the function mytheme_primary_links() in my template.php refreshed the cache so Drupal would add my theme function to the system then changed theme function on primary_links from links to my custom theme function primary_links - this allows me to customize only this 1 menu - could you do this and hook into where ever to change the theme function being called for your links?
