Updating Style From WP Options Setting Page
I think you have to solve this with jQuery. If checked -> addClass, if not -> removeClass. Here’s how to enqueue your JS file: add_action(‘admin_menu’, ‘fwds_plugin_settings’); function fwds_plugin_settings() { $hook = add_menu_page( ‘Price Display’, ‘Price Display’, ‘add_users’, ‘fwds_settings’, ‘fwds_display_settings’ ); add_action( “admin_print_scripts-$hook”, ‘fwds_print_scripts’ ); } function fwds_print_scripts() { wp_register_script( ‘my-fx’ , plugin_dir_url( __FILE__ ) . … Read more
Error on using __FILE__ for add_menu_page() Function

Tracing dashboard publish settings from input form in WordPress

Displaying $_FILES data (simlar to $_POST)
In order to show $_FILES or $_POST, you will need to create a sumbenu_page under the post_type. Then, you will be able to manipulate $_FILES and $_POST in whichever way you want. This means that upload_screen() function should be a submenu page.
Plugin admin list pages as submenu
You do not post how you add the top level menu page, however I think when you click on a submenu item you have an url like: http://www.example.com/wp-admin/admin.php?page=theme_admin_{$pageid} So the id of page is in the $_GET[‘page’] variable with a fixed string prepended to it. So why don’t use something like: function display_page_test() { $id … Read more
