Question

I want to register a script with wordpress that will work on the backend. I thought any script I registered in my functions.php file would work but it only shows in the front end. Anyone any ideas how to do this?

Answer 1

Try:

<?php

add_action( 'admin_head', 'myscriptinthe_admin_header' );
function myscriptinthe_admin_header(){
  echo "<script>alert( 'in the admin head!' )</script>";
}

add_action( 'admin_head', function(){ ?>    
<script> alert( 'in the admin head!' ) </script> 
<?php }); ?>
