如何通过自定义模块重写Drupal核心Tracker模块的菜单项标题？

Got it, the problem here is that hook_form_alter() is built for modifying form structures—not menu items. That’s why your attempts with it weren’t getting you anywhere! Let’s use the right tool for the job: hook_menu_alter(), which is specifically designed to tweak existing menu definitions from other modules.

Step 1: Create a Custom Module #

First, let’s make a simple custom module (we’ll call it custom_tracker_menu for this example):

1. Create a folder named custom_tracker_menu inside sites/all/modules/custom/ (make the custom folder if it doesn’t exist).
2. Add a .info file to define the module:

name = Custom Tracker Menu Override
description = Changes the title of the "Track" local task on user profiles from the Tracker module.
core = 7.x
package = Custom

Step 2: Implement hook_menu_alter() #

Add a .module file to the same folder with the following code:

<?php

/**
 * Implements hook_menu_alter().
 */
function custom_tracker_menu_menu_alter(&$items) {
  // Make sure the menu item exists before modifying it (avoids errors if Tracker is disabled)
  if (isset($items['user/%user/track'])) {
    // Replace this with your desired static title
    $items['user/%user/track']['title'] = 'Your Custom Title';

    // Optional: For a dynamic title (e.g., include the user's name), use these lines instead:
    // $items['user/%user/track']['title callback'] = 'custom_tracker_menu_dynamic_title';
    // $items['user/%user/track']['title arguments'] = array(1);
  }
}

/**
 * Custom title callback for the user track menu item (optional).
 */
function custom_tracker_menu_dynamic_title($account) {
  // Returns something like "Track John Doe"
  return t('Track @username', array('@username' => format_username($account)));
}

Step 3: Enable the Module & Clear Cache #

• Go to your Drupal site’s Modules page, find your new module, and enable it.
• Critical: Clear Drupal’s cache (you can do this via Configuration > Performance > Clear all caches). Menu changes won’t take effect until you clear the cache!

Key Notes #

• We check isset($items['user/%user/track']) to avoid PHP errors if the Tracker module is ever disabled.
• If you need a dynamic title (instead of static text), use the title callback and title arguments approach—it lets you generate the title based on context (like the user profile being viewed).
• Make sure the Tracker module is enabled, since we’re modifying a menu item it defines.
