It is fairly simple and straightforward on how to add contextual help tabs to various admin pages, and with the imminent advent of Genesis 1.8, adding contextual help will be as simple as a help() method. There are also a wide variety of great tutorials on how to add contextual help to admin pages, such as Justin Tadlock's Adding contextual help to plugin and theme admin pages.
However, there aren't any tutorials (at least that I could find) on how to add contextual help to edit/add-new post pages. So while I believe this may not be the best way to do this, it works! Being a pragmatist, it works for me!
[php]
// Add contextual help
add_action( 'add_meta_boxes' , 'wps_help' , 10 , 2 );
function wps_help ( $post_type , $post ) {
if ( 'page' == $post_type ) {
$my_help_tab_content = '<p>' . __( 'Lorem ipsum dolor sit amet, consectetur adipiscing elit. Nullam varius iaculis dui, eu ultricies velit consectetur pellentesque. Phasellus tortor mi, tempor eget pulvinar eu, sollicitudin ut eros. Quisque fermentum dolor elit. Aenean varius nisi placerat lectus elementum fringilla. Aenean at augue mauris, eu euismod mauris. Integer ac eros in ligula pharetra pretium. Pellentesque vel orci nibh. Pellentesque gravida velit ac lacus egestas eget imperdiet metus egestas. Maecenas tellus ligula, molestie ac pharetra id, tristique eu velit. Phasellus id quam in mi tristique gravida eget in quam. Cras ornare leo sed dui lobortis congue.') . '</p>';
get_current_screen()->add_help_tab( array(
'id' => 'my-help-id',
'title' => __( 'My Help Tab' ),
'content' => $my_help_tab_content,
) );
}
}
