Which Admin page am I on

I may not have expressed myself very well, and made a mistake at the crucial point–I will try again.

I am using ‘wp_enqueue_script’ to insert javascrip into the head (to configure TinyMCE). I really don’t want to do this on every page as TinyMCE gets used in many configurations–I just want to configure TinyMCE on my own page. How can I determine that I am on one of my own administrative pages in some code on the ‘admin_menu’ hook?

Normally code specific to your page gets placed in functions attached to the apropriate hooks (such as ‘add_options_page’). But once this code has been activated it is too late to be queueing up javascript, soo I have to find out whether my admin page is being displayed at an earlier point in the process (e.g., on the ‘admin_menu’ hook). Unfortunately the ‘page’ parameter in the $_POST arguments, used to select the admin page to display, seems to have been processed and removed by the time I come to insert (or not) the java script on the ‘admin_menu’ hook. None of my searches of the codex and source code have yet yielded the variable, function or class that I can use to find this information. I hope this is clearer. Sorry for the confusion.

I think this discussion might help.

OK I have solved my problem. There is a mechanism for enabling admin scripts on specific options pages; see admin_print_scripts-(page_hook) or admin_print_scripts-(plugin_page). This code fragment is all you need:

function myplugin_menu() {
  if ( function_exists('add_management_page') ) {
    $page = add_management_page( 'myplugin', 'myplugin', 9, __FILE__, 'myplugin_admin_page' );
    add_action( "admin_print_scripts-$page", 'myplugin_admin_head' );
  }
}

apljdi: Dead right; it was just what I was looking for, though I had got there by independent means. Thanks very much for your help.
