Tools pages
To add <head></head> content to a management page, the suffix for this hook should be in the following form:
add_action('admin_head-tools_page_myplugin/myplugin', 'myplugin_adminhead'); function myplugin_adminhead() { // Output <head> content here, e.g.: echo '<style type="text/css">' .'/* ... */' .'</style>'; }(From Codex)
Options pages
This hook is an action which means that it primarily acts as an event trigger, instead of a content filter. This is a semantic difference, but it will help you to remember what this hook does if you use it like this:
add_action( 'admin_menu', 'myplugin_setup_options' ); function myplugin_setup_options(){ $plugin_page=add_options_page( 'My Plugin', 'myplugin', 8, basename(__FILE__), 'myplugin_main' ); add_action( 'admin_head-'. $plugin_page, 'myplugin_admin_header' ); } function myplugin_admin_header(){ echo '<p>Only executes when the myplugin options page is displayed.</p>'; }
