I use this function and hook:
function mysite_admin_menu()
{
add_menu_page( 'Categories', 'Catégories', 'administrator', 'categories', 'a_function' );
add_submenu_page( 'categories', 'Manage', 'Manage', 'administrator', 'xxx', 'a_function' );
remove_submenu_page('categories','categories');
}
add_action( 'admin_menu', 'mysite_admin_menu' );
It displays what I need: a menu with a submenu on the left admin menu bar.
The thing is, the submenu leads to this page: admin.php?page=xxx
.
How can I do to link to a URL like edit-tags.php?taxonomy=category
?
If I swap the slug in the add_submenu_page
with a relative URL, the link will lead to
admin.php?page=edit-tags.php?taxonomy=category
.
Whatever I do, I always get admin.php?page=...
which is not what I want.

Reset to default 13This is an old post but can't you just use wordpress $menu
and/or $submenu
globals like Oleg suggested in number 2.
When in doubt copy WordPress:
wordpress/wp-admin/menu.php
For example to add link this seems like it would work:
function add_external_link_admin_submenu() {
global $submenu;
$permalink = admin_url( 'edit-tags.php' ).'?taxonomy=category';
$submenu['options-general.php'][] = array( 'Manage', 'manage_options', $permalink );
}
add_action('admin_menu', 'add_external_link_admin_submenu');
You can replace the $permalink = ...
with anything
So this should also work :
$permalink = 'http://www.example';
Also, it's suggested not to use 'administrator' (even though I use it as well. Anyway, read this ticket for alternative solutions.
I don't recommend you do that.
Let's assume your prefix for admin.php
is _trigger_me_
Submenu
<?php function _clean_url_to_repalce_admin_menu($url, $original_url, $_context){ if ($url == 'admin.php?page=_trigger_me_'){ remove_filter('clean_url', '_clean_url_to_repalce_admin_menu', 10); //return admin_url('someotherpage.php); return 'http://google/'; } } if (is_admin()) add_filter('clean_url', '_clean_url_to_repalce_admin_menu', 10, 3);
Main Menu
<?php function custom_admin_menu_action_hook(){ global $menu; foreach($menu as $k=>$item){ if ($item[2] == '_trigger_me_'){ $menu[$k][2] = 'http://google'; } } } add_action('admin_menu', 'custom_admin_menu_action_hook', 100);
I call both examples as "hacks". They possible to do, but better to not do that.
update.
if case if satisfied with redirection =)
<?php
$hook = add_submenu_page($parent, $title, $menu_title, 'manage_option', 'callback');
add_action("load-{$hook}", create_function('','
header("Location:", admin_url("someurl.php?blahblahblah"));
exit;
'));
in case if you want to substitute this by taxonomy page (edit-tags.php
)
<?php
add_action('admin_menu', 'admin_menu_edit_tags_page');
function admin_menu_edit_tags_page(){
// please set $YOURPARENTSLUG as parent slug of your menu item (parent of your menu)
// manage_tags to manage_terms of your taxonomy capability (its visible whan you var_dump($wp_taxonomies[$taxonomyyouwant]));
add_submenu_page($YOURPARENTSLUG, 'menu', 'title', 'manage_tags', 'edit-tags.php?taxonomy=taxonomy');
}
If your submenu is missing the admin.php?page=
prefix, you should register the parent menu first, then the submenu.
add_action( 'admin_menu', function() {
// Parent menu first
add_menu_page( 'Page title', 'Menu Title', 'capability', 'parent-slug', 'callback' );
// Then the submenus
add_submenu_page( 'parent-slug', 'Submenu Page Title', 'Submenu Title', 'capability', 'slug', 'callback' );
} );
Otherwise the link will be just the slug.
Thank you Oleg, your script works but breaks the admin interface (background colors and images all dissappear for any reason).
But if I have to take this road, I can do this instead:
function changeUrl()
{
$pageURL = 'http://'.$_SERVER["SERVER_NAME"].$_SERVER["REQUEST_URI"];
if ($pageURL == 'http://www.mysite/wp-admin/admin.php?page=xxxx')
{
header ('location:http://www.mysite/wp-admin/edit-tags.php?taxonomy=category');
}
}
add_action( 'admin_menu', 'changeUrl' );
It's seems curious to me that there is no simple way to link a submenu to any url. This kind of redirection is messy...but it works.
Although this is an old problem, I'd like to contribute for consideration this code:
function mysite_admin_menu()
{
add_menu_page( 'Categories', 'Catégories', 'administrator', 'categories', 'a_function' );
add_submenu_page( 'categories', 'Manage', 'Manage', 'administrator', 'manage_categories', 'mysite_manage_categories' );
remove_submenu_page('categories','categories');
}
add_action( 'admin_menu', 'mysite_admin_menu' );
function mysite_manage_categories()
{
?><script>window.location = "<?php echo admin_url('edit-tags.php?taxonomy=category'); ?>";</script><?php
}
it uses javascript redirect instead of creating another add_action to redirect via http.
