When I try to create a main menu, with this line
add_menu_page("page title","menu name",10,"test-slug");
Wordpress loads just fine and displays the new menu, but when I try to add a submenu,
add_menu_page("page title","menu name",10,"test-slug");
add_submenu_page("test-slug","sub title","sub menu",10,"test-sub-slug");
only an empty page is displayed, right after half a second. Seems like a php-error, but I can't see the error. Does anyone see what I am doing wrong?
Try the code below in your functions.php file. It should work correctly.
add_menu_page(
'Menu Page Title', // page title
'Menu Menu Text', // menu link text
'manage_options', // capability to access the page
'menu_slug', // page URL slug
'menu_callback_function', // callback function to display the content on options page
'dashicons-format-status', // menu icon
2 // priority
);
add_submenu_page(
'menu_slug', // page URL slug
'Sub Menu Title', // page title
'Sub Menu Text', // menu link text
'manage_options', // capability to access the page
'submenu_slug', // page URL slug
'submenu_callback_function', // callback function to display the content on options page
1 // priority
);
function menu_callback_function(){
echo "This is menu page...";
}
function submenu_callback_function(){
echo "This is submenu page...";
}
Problem solved. add_submenu_page() obviously must be called using a hook. Hence, this way it works and will not cause Wordpress to crash:
function dp_menu_item()
{
add_menu_page("page title","menu name","manage_options","mypage.php");
add_submenu_page("edit.php?post_type=cpt_people","sub title","sub menu","manage_options","mysubpage.php");
}
add_action("admin_menu", "dp_menu_item");
I have a custom page whose link is on secondary menu page.
Main Menu
- Secondary Menu
- - Custom page
When user go to custom page, secondary menu hides. Because of that to back to secondary menu page user needs to first click on Main menu and then secondary menu. I want to make Secondary menus visible on that custom page, so that user can directly click secondary menu.
How can I do that ??
You can place a block with the secondary menu in your custom page only, using the block configuration: admin>structure>block, find your secondary menu, configure it (display it on every pages you want), and then, place it on specific theme region.
I hope I'll help you :)
Try to print into your custom page below code.
<?php print theme('links__system_secondary_menu', array('links' => $secondary_menu, 'attributes' => array('id' => 'secondary-menu', 'class' => array('links', 'inline', 'clearfix')), 'heading' => t('Secondary menu'))); ?>
Thank You.
$menuItems = menu_tree_page_data('menu-name'); foreach($menuItems as $key => $m) { //check current active menu if ($m['link']['in_active_trail'] && $menuItems [$key]['below']) { $menu = menu_tree_output($menuItems [$key]['below']); } } //print the menu print $menu;
You can use this to show your menu on custom pages, you also add the HTML tags to make menu layout according theme.
I am new to wordpress development. I am trying to create a plugin but my top-level menu item is also being displayed as sub-menu item.below is my code.
<?php
/*
Plugin Name: rooties_main_menu
*/
add_action('admin_menu', 'gpwp_rooties_create_menu');
function gpwp_rooties_create_menu() {
add_menu_page('My Rooties Setting','Rooties Settings', 'manage_options', __FILE__, 'gpwp_rooties_setting_page',plugins_url('/images/wordpress.png',__FILE__) );
add_submenu_page(__FILE__, 'About Rooties Plugin', 'About', 'manage_options',__FILE__.'_about',gpwp_rooties_setting_about_page);
add_submenu_page(__FILE__, 'Today\'s Menu', 'Today\'s Menu', 'manage_options',__FILE__.'_about',gpwp_rooties_setting_menu_form_page);
}
?>
I know this is not the best code as per security prospects. I am trying these at my local system.
As per above code only "About" and "Today's menu" should be displayed as sub-menu but it is also displaying "Rooties Settings" too. Please let me know where i am wrong.
From the Codex: http://codex.wordpress.org/Adding_Administration_Menus#Using_add_submenu_page
For existing WordPress menus, the PHP file that handles the display of
the menu page content. For submenus of a custom top-level menu, a
unique identifier for this sub-menu page.
In situations where a plugin is creating its own top-level menu, the
first submenu will normally have the same link title as the top-level
menu and hence the link will be duplicated. The duplicate link title
can be avoided by calling the add_submenu_page function the first time
with the parent_slug and menu_slug parameters being given the same
value.
There are some code examples here, although they are old -> http://wordpress.org/support/topic/add_menu_page-always-add-an-extra-subpage
Before:
add_menu_page('Section', 'Section', 10, __FILE__, 'section');
add_submenu_page(__FILE__, 'Edit', 'Edit', 10, 'section-edit', 'section_edit');
Fixed:
add_menu_page('Section', 'Section', 10, __FILE__, 'section');
add_submenu_page(__FILE__, 'Edit', 'Edit', 10, __FILE__, 'section_edit');
I crete a custom post type with a taxonomy and all works fine.
WordPress create a main menu:
MyCustomPost
+----------> MyCustomPost
+----------> Add New
+----------> My Taxonomy
However, I like to create a my own menu, like this:
MyTitle
+----------> MyCustomPost
+----------> Add New
+----------> My Taxonomy
So, I create a my own menu:
$menu_main = add_menu_page( 'MyMenu', 'MyMenu', 'edit_posts', 'my_menu_key', array( $this, 'menu_main'), $icon_menu, 100 );
When register my custom post type I set show_in_menu with my_menu_key, and its works.
MyMenu
+----------> MyCustomPost
The question is: where is taxonomy? and `Add New sub menu?
Any idea?
Nice trick with show_in_menu. But the taxonomy sub-menu is built in a hard-coded manner and register_taxonomy doesn't take any parameter like that. Probably, the Add New submenu works the same way.
A workaround is to manipulate the global $submenu:
// PHP 5.3+ anonymous function
add_action( 'admin_init', function() {
global $submenu;
$submenu['my_menu_key'][10] = $submenu['edit.php?post_type=YOUR-CPT-SLUG'][10];
$submenu['my_menu_key'][15] = $submenu['edit.php?post_type=YOUR-CPT-SLUG'][15];
});
Instead of manipulating the $submenu global, you can accomplish this by using built-in WordPress functions for better future compatibility.
add_action('admin_menu', 'add_tax_menus');
function add_tax_menus() {
$key = 'edit.php?post_type=CUSTOM_POST_TYPE_SLUG';
add_submenu_page($key, 'My Page Title', 'My Menu Title', 'manage_categories', 'edit-tags.php?taxonomy=TAXONOMY_SLUG&post_type=CUSTOM_POST_TYPE_SLUG');
}
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.
