Hi Marco, Glad you found the article useful. This article is a little out of date now. Take a look at this: WordPress $current_screen variable for admin screens

Hello, and thank you for the useful page.
I didn’t find any follow-up post about page hooks,so I am asking if you could give me some detail.
If I look in the HEAD of my page I don’t see any reference to page hooks. But there is a line inside a small JS snippet that reads:
var pagenow = 'toplevel_page_MoxiemailManagementWidget'
MMWidget is the plugin I am developing.
Is this the $page_hook?
I’m using WP 3.3 and I am in the admin section.
Thanks in advance, Marco

I figured out that in the add_action function you need to specify the number of arguments the action function takes, which is 2 in this case.

I changed it to: add_action( ‘contextual_help’, ‘my_function’ ,10,2);

I also change the $text variable in the actual function to $contextual_help. Not sure if that is related though.

Hi Philip, I'll write up an article on it in the next day or two. Here's some info to get you going in the meantime... Normally you will add your Theme Options page like this (simplified for posting here):

add_action('admin_menu', 'add_my_theme_options_page');
function add_my_theme_options_page() {
	$page_hook = add_submenu_page(args, etc etc);
}

The variable $page_hook is what you want. Of course, you will need to be careful with variable scope to make sure you can access this elsewhere. A quick way to find your page hook is to look at the Page Source of your Theme Options page - you will see it in the HEAD section.

I love this concept. Would be really useful when developing themes for clients’ sites.

Can you offer any links to where I can learn more about how and where page hooks are defined?

Hi, Without seeing all your code it's difficult to say what the problem may be. You don't need to make either $screen or $text global because they are the arguments passed to your function by the add_action filter. Without the filter, nothing will work. The code in the article will work in WPMU 2.8.6.

i love the idea. But i encounter a problem when i try to use your snipet

i got this error code :Warning: Missing argument 2 for my_admin_help() in C:xampphtdocsmyblogwp.comwp-contentpluginsbakaautoblogcoreadminlayout.php on line 31

i believe there’s problem on $screen variabel. i had make it global variabel but it still send error.

by the way, right now i use wpmu Version 2.8.6 as development environtment. i use it using xampp on my localhost. i use your snippet as part of a plugin. i believe where and what version or what kind of wordpress i use is not the main problem. I hope you can help me.
