It's pretty standard, I enqueue script and style for admin page.
function admin_custom(){
wp_enqueue_script('js', plugins_url('adm.js', __FILE__));
wp_enqueue_style('css', plugins_url('adm.css', __FILE__));
}
add_action('admin_enqueue_scripts', 'admin_custom');
The result:
<link rel='stylesheet' id='css-css' href='http://localhost/wp/wp-content/plugins/manager/adm.css?ver=3.5.1' type='text/css' media='all' />
<script type='text/javascript' src='http://localhost/wp/wp-content/plugins/manager/adm.js?ver=3.5.1'></script>
But it doesn't work. Style is working, but the script is not loaded. I put the css and js in the same folder. It doesn't make sense for me. Any help will be appreciated, I spent last day for this problem. Thanks!
