How to add your custom CSS or JS on admin screen? Well, it’s pretty easy. We need to hook into admin_enqueue_scripts action and this is the best and only solution. So, let’s write some code:
|
1 2 3 4 5 6 7 8 |
if ( is_admin() ) { add_action( 'admin_enqueue_scripts', 'my_admin_enqueue_scripts' ); } function my_admin_enqueue_scripts( $hook ) { wp_enqueue_style( 'my-stylesheet', plugins_url( 'css/admin.css', __FILE__ ) ); wp_enqueue_script( 'my-script', plugins_url( 'js/admin.js', __FILE__ ) ); } |
Please note the $hook variable. Thanks to its value you may enqueue your scripts/styles depending on active admin screen. It is important, because you should not enqueue your scripts or styles where it isn’t necessary.
Second thing, first conditional is_admin. It’s pretty obvious, but I have to mention it. Do not even hook into admin_enqueue when you are not on admin screen.
This is a great explanation. I have dabbled in this, but didn’t always know what I was doing! This helped me to understand some of the basics.
