add_contextual_help deprecated – need help

correction–noticed an extra comma

New code:

get_current_screen()->add_help_tab( array(
   'id' => 'theme_options_help_tab',
   'title' => __('Theme Options Help Tab'),
   'content' => $help
) );

What action are you hooking this to?

The way it works is that you create an admin page, then you can hook to it so that it will do stuff when that page is loaded. Like this:

add_action('admin_menu', 'example_menu_add');
function example_menu_add() {
// add the menu item and screen
$hook = add_menu_page( 'Whatever', 'Whatever', 'manage_options', 'whatever', 'whatever_admin' );
add_action( "load-$hook", 'example_menu_load' );
}

In the function that is hooked to that load-$hook, I can call get_current_screen() and get back a valid object. But I can’t just call get_current_screen from anywhere, because the screen object might not exist yet. The load-$hook is the hook for my specific screen, and it will get called to create the info for my screen, so then I can be assured that get_current_screen() will return something meaningful.

Thanks, Samuel. I have the following:

/**
 * Add our theme options page to the admin menu, including some help
 * documentation.
 *
 * This function is attached to the admin_menu action hook.
 */
function abc_theme_options_add_page() {

$theme_page = add_theme_page(
		__( 'Theme Options', 'abc' ),   // Name of page
		__( 'Theme Options', 'abc' ),   // Label in menu
		'edit_theme_options',    // Capability required
		'theme_options',   // Menu slug, used to uniquely identify the page
		'abc_theme_options_render_page' // Function that renders the options page
	);

	if ( ! $theme_page )
		return;

	$help = '<p>'.__('Some help text').'</p>';

	 get_current_screen()->add_help_tab( array(
		'id' => 'my_help_tab',
		'title' => 'My Help Tab',
		'content' => $help
	 ));

	//add_contextual_help( $theme_page, $help );
}
add_action( 'admin_menu', 'abc_theme_options_add_page' );

You need to move the function calls that add the help page out into their own function with a different hook. Like this:

function abc_theme_options_add_page() {

$theme_page = add_theme_page(
		__( 'Theme Options', 'abc' ),   // Name of page
		__( 'Theme Options', 'abc' ),   // Label in menu
		'edit_theme_options',    // Capability required
		'theme_options',   // Menu slug, used to uniquely identify the page
		'abc_theme_options_render_page' // Function that renders the options page
	);

	add_action( "load-$theme_page", 'abc_theme_options_add_help' );
}
add_action( 'admin_menu', 'abc_theme_options_add_page' );

function abc_theme_options_add_help() {
	$help = '<p>'.__('Some help text').'</p>';

	 get_current_screen()->add_help_tab( array(
		'id' => 'my_help_tab',
		'title' => 'My Help Tab',
		'content' => $help
	 ));
}

Edit: The hook should be "load-$theme_page", with a dash, not an underscore like I typo’ed a moment ago.

Thanks so much Samuel–much appreciated. Worked like a charm!

Just used this to update a theme options page as well, thanks Otto!
