Admin Conditionals

Basic Admin Detection

is_admin() // Returns true for ANY admin page (including AJAX requests)

Check Specific Admin Pages

// For plugin/theme options pages
function is_my_plugin_admin_page() {
    $screen = get_current_screen();
    return ($screen->base === 'toplevel_page_my-plugin-slug');
}

// For post type edit screens
function is_custom_post_edit_screen() {
    $screen = get_current_screen();
    return ($screen->post_type === 'my_cpt' && $screen->base === 'post');
}

📋 Post Editor Conditions

Post Type Editor

function is_post_editor() {
    global $pagenow;
    return (is_admin() && $pagenow === 'post.php');
}

function is_new_post_screen() {
    global $pagenow;
    return (is_admin() && $pagenow === 'post-new.php');
}

Gutenberg vs Classic Editor

function is_gutenberg_editor() {
    $screen = get_current_screen();
    return method_exists($screen, 'is_block_editor') && $screen->is_block_editor();
}

🗂️ List Table Screens

Post List Table

function is_post_list_table() {
    global $pagenow;
    return (is_admin() && $pagenow === 'edit.php');
}

// For custom post types
function is_custom_post_list() {
    $screen = get_current_screen();
    return ($screen->base === 'edit' && $screen->post_type === 'my_cpt');
}

⚙️ Special Admin Pages

Plugin/Theme Admin Pages

function is_plugins_page() {
    global $pagenow;
    return (is_admin() && $pagenow === 'plugins.php');
}

function is_theme_customizer() {
    global $pagenow;
    return (is_admin() && $pagenow === 'customize.php');
}

User Profile Screen

function is_user_profile_page() {
    global $pagenow;
    return (is_admin() && ($pagenow === 'profile.php' || $pagenow === 'user-edit.php'));
}

🛡️ Advanced Conditional Checks

Combined with Hook Suffixes

add_action('admin_enqueue_scripts', function($hook) {
    // Only load on our plugin's settings page
    if ($hook !== 'toplevel_page_my-plugin-slug') return;
    wp_enqueue_script('my-admin-script');
});

Checking Admin AJAX Requests

function is_my_plugin_ajax() {
    return (defined('DOING_AJAX') && DOING_AJAX && 
            isset($_REQUEST['action']) && 
            strpos($_REQUEST['action'], 'myplugin_') === 0);
}

Admin Area with GET/POST Parameters

function is_specific_admin_context() {
    return (is_admin() && 
            isset($_GET['page']) && 
            $_GET['page'] === 'my-plugin-page' &&
            isset($_GET['tab']) && 
            $_GET['tab'] === 'advanced');
}

if (!current_user_can('edit_posts')) return;

is_network_admin() // Multisite only

add_action('admin_footer', function() {
    echo '<pre>'.print_r(get_current_screen(), true).'</pre>';
});
