How Can I Rename an Admin Menu Submenu Label in WordPress?

Customizing the WordPress admin dashboard can significantly enhance the user experience, especially when tailoring the interface to fit specific workflows or client needs. One subtle yet impactful way to personalize this environment is by renaming admin menu submenu labels. This simple adjustment can clarify navigation, reduce confusion, and make the backend feel more intuitive and aligned with your site’s unique structure.

Renaming admin menu submenu labels isn’t just about aesthetics; it’s about improving usability and streamlining access to essential features. Whether you’re managing a complex multisite network or fine-tuning a single installation, adjusting these labels can help highlight the most relevant tools and hide or rename less-used options. This approach empowers site administrators and contributors alike, fostering a more productive and user-friendly backend experience.

In the following sections, we’ll explore the reasons behind renaming submenu labels, the benefits it brings, and the best practices to implement these changes effectively. By understanding the fundamentals, you’ll be equipped to customize your WordPress admin menu in a way that truly supports your site management goals.

Techniques to Rename Admin Menu Submenu Labels in WordPress

Renaming submenu labels in the WordPress admin menu involves interacting with the global `$submenu` array, which stores all submenu items. Each submenu item is an array containing the submenu title, capability, menu slug, and optional icon or callback. Modifying the label requires identifying the correct submenu and updating its title value.

The general approach includes:

Hooking into the `admin_menu` action with a priority after the menu items are registered (commonly priority 999).
Accessing the global `$submenu` array.
Locating the submenu by its parent menu slug and submenu slug.
Reassigning the submenu label to a new string.

Below is a sample code snippet illustrating this process:

“`php
add_action(‘admin_menu’, ‘custom_rename_submenu_label’, 999);
function custom_rename_submenu_label() {
global $submenu;
$parent_slug = ‘tools.php’; // Example parent menu slug
$submenu_slug = ‘import.php’; // Example submenu slug to rename

if ( isset($submenu[$parent_slug]) ) {
foreach ( $submenu[$parent_slug] as &$submenu_item ) {
if ( $submenu_item[2] === $submenu_slug ) {
$submenu_item[0] = ‘New Import Label’; // New label text
break;
}
}
}
}
“`

In this example:

`$submenu[$parent_slug]` accesses the array of submenu items under the specified parent.
Each `$submenu_item` is checked against the target slug.
Once found, the first element of the submenu item array, which represents the label, is updated.

Common Parent Menu Slugs and Corresponding Submenus

When renaming submenu labels, knowing the exact parent menu and submenu slugs is essential. Below is a table listing common parent menus with example submenu slugs that are frequently modified.

Parent Menu Slug	Submenu Slug	Default Submenu Label
tools.php	import.php	Import
tools.php	export.php	Export
options-general.php	options-writing.php	Writing
options-general.php	options-reading.php	Reading
edit.php?post_type=page	post-new.php?post_type=page	Add New
edit.php	post-new.php	Add New

Best Practices and Considerations

Renaming admin menu submenu labels should be done cautiously to maintain clarity and avoid confusion among site administrators. Consider the following best practices:

Backup Before Changes: Always backup your site or test changes on a staging environment to prevent unintentional disruptions.
Use Unique Slugs: Confirm the exact slug for the submenu to avoid renaming the wrong item.
Localization Support: If your site supports multiple languages, ensure that the new labels are translatable using functions like `__()` or `_e()`.
Avoid Conflicts: Use a unique function name when hooking into `admin_menu` to prevent conflicts with other plugins or themes.
Use Late Priority: Assign a higher priority number (e.g., 999) to the hook callback to ensure it runs after all menus are registered.
Consider Accessibility: Ensure the new labels remain descriptive and accessible to all users.

Alternative Methods Using Plugins or Filters

While direct modification of the `$submenu` array is the most straightforward method, alternative approaches include:

Admin Menu Editor Plugins: Plugins such as “Admin Menu Editor” provide graphical interfaces to rename, reorder, or hide menu items without coding.

Using `menu_page_title` Filter: This filter can be used to modify the page title but does not affect the menu label directly.

Custom Admin Pages: For complete control, developers may unregister existing menus and add new ones with custom labels, but this is more complex and generally unnecessary for simple renaming tasks.

Summary of Key Functions and Variables

Below is a brief reference of key components involved in renaming submenu labels.

Component	Description
`$submenu`	Global array holding all submenu items indexed by parent menu slugs.
`admin_menu` action	WordPress hook used to add or modify admin menus and submenus.
`add_action()`	Function to hook custom functions into WordPress actions such as `admin_menu`.
Submenu item array	Array containing submenu label, capability, slug, and callback, e.g. `['Import', 'manage_options', 'import.php']`.

Methods to Rename Admin Menu Submenu Labels in WordPress

Renaming submenu labels in the WordPress admin menu allows developers to customize the dashboard interface for better clarity or branding. This adjustment is commonly achieved through hooks and filters within the `functions.php` file or a custom plugin.

The primary mechanism to rename submenu labels relies on accessing and modifying the global `$submenu` array, which stores all submenu items for each top-level menu. By targeting the correct submenu slug and adjusting its label, the displayed text changes accordingly.

Using the Global `$submenu` Array

The `$submenu` global variable is a multidimensional associative array structured as follows:

Key	Description
Top-level menu slug	Associative array of submenu items belonging to this menu
Submenu index	Array containing submenu item details (label, capability, slug)
Label	The displayed name of the submenu

Example structure:

$submenu['tools.php'][10] = array('Available Tools', 'manage_options', 'tools.php?tool=available-tools');

Implementation Example

To rename a submenu label, you can hook into the admin_menu action and modify the label directly:

add_action('admin_menu', function() {
    global $submenu;
    if ( isset($submenu['tools.php'][10][0]) ) {
        $submenu['tools.php'][10][0] = 'Custom Tools Label';
    }
});

Key considerations:

Confirm the top-level menu slug (e.g., `tools.php`, `edit.php`) and the submenu index you want to rename.
Use the exact index of the submenu item, which can be determined by inspecting the `$submenu` array.
Wrap changes in a function hooked to admin_menu to ensure the menu is already registered.

Finding the Correct Submenu Index

Since submenu indexes are numeric and can vary, it is useful to debug the existing submenu structure:

add_action('admin_menu', function() {
    global $submenu;
    error_log(print_r($submenu['tools.php'], true));
});

This logs the submenu array for the “Tools” menu, showing all submenu items and their indexes in the debug log. Based on this output, you can identify which index to target for renaming.

Alternative: Using `add_submenu_page` to Override Labels

If you want to replace a submenu item completely, you can unregister the existing submenu and register a new one with the desired label:

Remove the default submenu using the `remove_submenu_page()` function.
Add a new submenu with `add_submenu_page()` using the custom label.

add_action('admin_menu', function() {
    remove_submenu_page('tools.php', 'tools.php?tool=available-tools');
    add_submenu_page(
        'tools.php',
        'Custom Tools Label',
        'Custom Tools Label',
        'manage_options',
        'tools.php?tool=available-tools'
    );
});

This method gives full control over submenu labels but requires knowing the submenu slug exactly and might affect plugin compatibility.
