[wp-hackers] How to prevent loading admin components?

[Dion Hulse (dd32)]

You'll need to hook into an early hook in the admin section for your page.

Add
add_action('all', create_function('', 'var_dump(current_filter());'));
to your plugin file,it'll print the name of every action hook which is run.

For example, I can see amongst it all, This hook:  
"load-settings_page_revision-control" for the page  
wp-admin/options-general.php?page=revision-control

Yours will be something like "load-tools_name_of_my_plugin", But it'll  
vary, so if you dump and then look for the action hook starting with  
"load-" you'll be right.

Example code to use would be:

add_action('load-settings_page_revision-control', 'rc_page');
function rc_page() {
	iframe_header();
	echo '<h1>Hello World!</h1>';
	iframe_footer();
	exit; //Die to prevent the page continueing loading and adding the admin  
menu's etc.
}

A tricky thing you can do, Is if you know the page may load in thickbox or  
normal, is to hook that action to thesame as the menu name, and then check  
if it was loaded in TB or not:

add_menu_page('......', 'rc_page');
add_action('load-settings_page_revision-control', 'rc_page_maybe_iframe');

function rc_page_maybe_iframe() {
	if ( isset($_GET['TB_iframe']) )
		return; // If the TB Iframe marker is not set, then its been loaded via  
Thickbox, But if it IS set, then Thickbox has not been used.
	iframe_header();
	rc_page();
	iframe_footer();
	exit; //Die to prevent the page continueing loading and adding the admin  
menu's etc.
}
function rc_page() {
	echo '<h1>Hello World!</h1>';
}

Thats good for users without Javascript, and those of us who Middle-click  
to open in a new tab or whatever.. Get the thickbox without the menu's if  
within thickbox, else get the menu's and a easy way of navigating away  
otherwise.

as for iframe_header(), i'd advise you use those, you can check out the  
code for them in wp-admin/includes/template.php i think, else its misc.php.
reason being, is that it prints the scripts/styles as well as the footer  
stuff and all that..
