Hello Kurak,

Here is a simple solution to your problem using jQuery:

if ( is_admin() ) {
    function add_post_enctype() {
        echo "<script type='text/javascript'>
                  jQuery(document).ready(function(){
                      jQuery('#post').attr('enctype','multipart/form-data');
                  });
              </script>";
    }
    add_action('admin_head', 'add_post_enctype');
}

If you want to test for a particular admin page for example “add page” or “edit-page” here is a slightly improved version of the same script:

if ( is_admin() ) {
    $current_admin_page = substr( strrchr( $_SERVER['PHP_SELF'], '/' ),1, -4 );
    if ( $current_admin_page == 'page' || $current_admin_page == 'page-new' ) {
        function add_post_enctype() {
            echo "<script type='text/javascript'>
                      jQuery(document).ready(function(){
                          jQuery('#post').attr('enctype','multipart/form-data');
                  });
                  </script>";
        }
        add_action( 'admin_head', 'add_post_enctype' );
    }
}

Using this method you can add all sorts of attributes or html to the admin pages when and where needed.
