[wp-hackers] Custom post publish: show error $notice in stead of update $message

[Barry Ceelen]

Thanks a lot for pointing out the admin_notices action, Andrew :)

Problem solved:

add_action( 'admin_notices', 'my_custom_post_type_admin_notices' );

function my_custom_post_type_admin_notices() {

	global $pagenow;

	if ( 'post.php' != $pagenow ) // Only show notice, if any, on the post edit screen
		return;

	if ( $post->post_type == 'my_custom_post_type' && isset( $_GET['message'] ) && $_GET['message'] == 'some_variable' )
		echo '<div class="error"><p><strong>Note: </strong> please provide some missing info</p></div>';
}
