I tried both hierarchical true and false and it didn’t show up. I can accept it isn’t possible.

@bcworkz Thanks, I understand what you meant now, and it is working. Here are my new files:

// main.php

if (is_admin()) {
    require_once plugin_dir_path(__FILE__) . 'activate-deactivate.php';
}

// activate-deactivate.php

function my_plugin_on_activation()
{
    if (!current_user_can('activate_plugins')) {
        return;
    }

    $plugin = isset($_REQUEST['plugin']) ? $_REQUEST['plugin'] : '';
    check_admin_referer("activate-plugin_{$plugin}");

    // other stuff that should happen...
}
register_activation_hook(WP_PLUGIN_DIR . '/my-plugin/main.php', 'my_plugin_on_activation');

function my_plugin_on_deactivation()
{
    if (!current_user_can('activate_plugins')) {
        return;
    }

    $plugin = isset($_REQUEST['plugin']) ? $_REQUEST['plugin'] : '';
    check_admin_referer("deactivate-plugin_{$plugin}");

    // other stuff that should happen...
}
register_deactivation_hook(WP_PLUGIN_DIR . '/my-plugin/main.php', 'my_plugin_on_deactivation');

@bcworkz I think I tried what you said, but that didn’t work either. Here’s the setup:

my-plugin
  |-main.php
  |-activate-deactivate.php

// main.php

if (is_admin()) {
    // I tried both of these with the same result
    require_once plugin_dir_path(__FILE__) . 'activate-deactivate.php';
    // or
    require_once WP_PLUGIN_DIR . '/my-plugin/activate-deactivate.php';
}

// activate-deactivate.php

function my_plugin_on_activation()
{
    if (!current_user_can('activate_plugins')) {
        return;
    }

    $plugin = isset($_REQUEST['plugin']) ? $_REQUEST['plugin'] : '';
    check_admin_referer("activate-plugin_{$plugin}");

    // other stuff that should happen...
}
register_activation_hook(__FILE__, 'my_plugin_on_activation');

function my_plugin_on_deactivation()
{
    if (!current_user_can('activate_plugins')) {
        return;
    }

    $plugin = isset($_REQUEST['plugin']) ? $_REQUEST['plugin'] : '';
    check_admin_referer("deactivate-plugin_{$plugin}");

    // other stuff that should happen...
}
register_deactivation_hook(__FILE__, 'my_plugin_on_deactivation');

Again, these functions work from within main.php, but not when placed in their own file.

Feeling a little dumb, just checked my hidden input and had name="acion" instead of action. I tried to delete this thread but couldn’t figure it out.

@bcworkz Got it! Thanks!

@joyously yes my-plugin.php has the headers.

@howdy_mcgee @bcworkz This is what I ended up with in my-plugin.php. I tried the @param String $hook but I couldn’t get it to work after multiple attempts of different iterations I found across the web. I would like to learn it, if possible, as it seems it would be easier and make the code more readable. If you have anymore suggestions towards that I would appreciate it.

if (!defined("ABSPATH")) {
    exit;
}

if (is_admin()) {
    require_once plugin_dir_path(__FILE__) . "admin/admin-menu.php";
    require_once plugin_dir_path(__FILE__) . "admin/settings-page.php";
}

function my_plugin_styles()
{
    if (get_current_screen()->id !== "toplevel_page_my-plugin") {
        return;
    }
    wp_enqueue_style(
        "custom_wp_admin_css", plugins_url("admin/css/style.css", __FILE__)
    );
}

add_action("admin_enqueue_scripts", "my_plugin_styles");

Thanks @joyously, that was the info I was looking for. I guess the index.php was a little redundant.

Thanks @howdy_mcgee as well. That was the information I was finding, but uncertain as to where it was supposed to go.
