Add sort function to column (fix attached ;))

Hey there, in one of the reviews i saw another user (@florisassies) suggesting to include a sort function.

Now i’m no coder but i asked ChatGPT and it tweaked the plugin and it works.

<?php
/**
 * Admin Slug Column (Streamlined Version)
 *
 * @package           Admin_Slug_Column_Simplified
 * @wordpress-plugin
 * Plugin Name:       Admin Slug Column (Streamlined)
 * Description:       Adds a sortable "Slug" column to the admin posts/pages list without additional columns.
 * Version:           1.0
 * Author:            Adapted Plugin

// If this file is called directly, abort
if ( ! defined( 'WPINC' ) ) {
    die;
}

// Only run plugin in the admin
if ( ! is_admin() ) {
    return;
}

// Add slug column to admin posts/pages lists
function add_slug_column($columns) {
    $columns['slug'] = __('Slug');
    return $columns;
}
add_filter('manage_posts_columns', 'add_slug_column');
add_filter('manage_pages_columns', 'add_slug_column');

// Populate slug column with the post slug
function display_slug_column_content($column, $post_id) {
    if ($column === 'slug') {
        $post = get_post($post_id);
        echo esc_html($post->post_name); // Display the post slug
    }
}
add_action('manage_posts_custom_column', 'display_slug_column_content', 10, 2);
add_action('manage_pages_custom_column', 'display_slug_column_content', 10, 2);

// Make slug column sortable
function add_slug_column_sortable($columns) {
    $columns['slug'] = 'slug';
    return $columns;
}
add_filter('manage_edit-post_sortable_columns', 'add_slug_column_sortable');
add_filter('manage_edit-page_sortable_columns', 'add_slug_column_sortable');

// Modify the query to sort by slug when requested
function sort_by_slug_column($query) {
    if (!is_admin() || !$query->is_main_query()) {
        return;
    }
    $orderby = $query->get('orderby');
    if ('slug' == $orderby) {
        $query->set('orderby', 'name');  // 'name' represents the slug in the database
    }
}
add_action('pre_get_posts', 'sort_by_slug_column');
