add_contextual_help() WordPress Function

The add_contextual_help() function is used to add contextual help to a WordPress admin screen. The function takes two arguments: the screen ID and the help text. The screen ID is the ID of the screen where you want to display the help text. The help text can be either a string or an array.

add_contextual_help( string $screen, string $help ) #

	_deprecated_function( __FUNCTION__, '3.3.0', 'get_current_screen()->add_help_tab()' );

	if ( is_string( $screen ) )
		$screen = convert_to_screen( $screen );

	WP_Screen::add_old_compat_help( $screen, $help );
