well it looks like I worked this out. On the actual admin page I need to declare my $errors array as global as well global $errors; I guess wordpress must somehow box the admin page into a function and so the $errors array was not referencing the global var.
Hmm – if they have no role, it may be that they are coming in through some other way and adding that action will not help. What plugins do you have active ? also are you sharing a wp user database with another system?
I have Multi-Site enabled. That means I must first log in as a super admin, then go to “super admin” > “themes” option in left menu (inside wp-admin), and then enable it there first.
Don’t know if this could help you, I used this to manage a image field from a meta-box in the post admin page : add_action( ‘load-post.php’, ‘ImageOnSlider_scripts’ ); add_action( ‘load-post-new.php’, ‘ImageOnSlider_scripts’ ); function ImageOnSlider_scripts() { wp_enqueue_script(‘media-upload’); wp_enqueue_script(‘thickbox’); wp_register_script(‘my-upload’, WP_THEME_URL.’/js/name_of_script.js’, array(‘jquery’,’media-upload’,’thickbox’)); wp_enqueue_script(‘my-upload’); wp_enqueue_style(‘thickbox’); } and the JS : jQuery(document).ready(function() { jQuery(‘#upload_image_button’).click(function() { formfield = jQuery(‘#input-ImageOnSlider’).attr(‘name’); tb_show(”, … Read more
