Explanation

Want to add your own links to the WordPress admin toolbar? This code snippet does just that, making it easier to access your favorite pages directly from the toolbar.

Here's what it does:

First, it checks if the user has the right permissions (like an admin) to see the toolbar changes. If not, it skips the rest.
It adds a new link to the toolbar. This link can point to any URL you want, like an external website. You can customize the link's title, tooltip, and even make it open in a new tab.
It also adds a sub-link under the existing "site-name" menu in the toolbar. This one links to the Posts page in your WordPress admin area, but you can change it to any admin page you prefer.

To make it your own:

Change the URL in the first link to wherever you want it to go.
Adjust the titles and tooltips to better describe your links.
Feel free to add more links by copying the structure and modifying as needed.

This is a handy way to customize your WordPress admin experience without needing a plugin!

Code
<?php
// Hook into 'admin_bar_menu' to add custom links to the WordPress admin toolbar
add_action('admin_bar_menu', 'wp_dudecom_customize_admin_bar', 100);

function wp_dudecom_customize_admin_bar($wp_admin_bar) {
    // Check if the current user has the capability to view the admin bar
    if (!current_user_can('manage_options')) {
        return;
    }

    // Add a custom link to the admin toolbar
    $wp_admin_bar->add_node(array(
        'id'    => 'wp-dudecom-custom-link',
        'title' => 'Custom Link',
        'href'  => 'https://example.com', // Replace with your desired URL
        'meta'  => array(
            'title' => __('Visit Custom Link'), // Tooltip text
            'target' => '_blank', // Open link in a new tab
            'class' => 'wp-dudecom-custom-class' // Custom CSS class
        ),
    ));

    // Add another custom link under the existing 'site-name' node
    $wp_admin_bar->add_node(array(
        'parent' => 'site-name',
        'id'     => 'wp-dudecom-sub-link',
        'title'  => 'Sub Link',
        'href'   => admin_url('edit.php'), // Link to the Posts page in the admin area
        'meta'   => array(
            'title' => __('Go to Posts'), // Tooltip text
        ),
    ));
}
?>
