WP 3.0 – Problems enqueueing javascript with specific target

    My organization requires that I use WordPress 3.0 to create a new plugin. I’m having trouble getting one of my scripts to load to *only* my Options page (accessed as admin from the dashboard). When I enqueue it without a target page hook, the script successfully loads on every page, but I don’t want that. Here’s a few code snippets:

    In my sidebar loader:
    define( OPTIONS_PAGE, add_menu_page('EMS Forms Options', 'EMS Forms', 'manage_options', PATH.'/EMSF_Options.php') );

    In my main file:
    add_action('admin_print_scripts-'.OPTIONS_PAGE, 'Add_EMSF_Options_Scripts');

    And here’s the function that the main file is assigning the action…

    function Add_EMSF_Options_Scripts(){
wp_register_script('EMSF_Options, plugins_url('emsforms/js/EMSF_Options.js'), array('jquery','jquery-form'), '1.0');
wp_enqueue_script('EMSF_Options');
}

    Any help with this would be greatly appreciated. I suppose I could just let it load the script on every page, but I’d rather not, since it uses jquery’s ajax functionality every time it loads.

    Thanks in advance.

    accessed as admin from the dashboard

    Use is_admin() or is_user_logged_in()

    function Add_EMSF_Options_Scripts(){
	if( is_admin() ) {
		wp_register_script('EMSF_Options, plugins_url('emsforms/js/EMSF_Options.js'), array('jquery','jquery-form'), '1.0');
		wp_enqueue_script('EMSF_Options');

	}
}

    I have just read it again, is there something in the url that you can use as a condition, try to echo $pagename and see what it returns and then?

    function Add_EMSF_Options_Scripts(){
	global $pagenow;
	if ( $pagenow == 'emsf_options.php' ) {
	if( is_admin() ) {
		wp_register_script('EMSF_Options, plugins_url('emsforms/js/EMSF_Options.js'), array('jquery','jquery-form'), '1.0');
		wp_enqueue_script('EMSF_Options');

	}
}

    The second method (using strpos to find the page name in the URL) would almost certainly work for me, but $pagenow is empty. Were you just using that as an example, or is that actually supposed to be a wordpress global var?

    I got the syntax wrong, I was developing a plugin, here is the options code snippet that may help.

    global $pagenow;
if ( $pagenow == 'admin.php' && $_GET['page'] == 'raindrops' ) :

    So if it is an options page check the url for the $pagenow and the page will be your pagename, mine was raindrops.php so ‘raindrops’

    global $pagenow;
if ( $pagenow == 'admin.php' && $_GET['page'] == ''emsf_options' ) :

    I have used the global $pagenow in a plugin for $pagenow == 'post.php' and $pagenow == 'new-post.php' so I know it works, not sure from which version as I always have the latest.

    If I run the wp-pagenavi options page I have:
    wp-admin/options-general.php?page=pagenavi

    That would be:

    global $pagenow;
if ( $pagenow == 'admin.php' && $_GET['page'] == 'pagenavi' ) :

    or:

    global $pagenow;
if ( $pagenow == 'options.php' && $_GET['page'] == 'pagenavi' ) :

    or:

    global $pagenow;
if ( $pagenow == 'general-options.php' && $_GET['page'] == 'pagenavi' ) :
