Inspiring Quote – Nothing is done

September 19th, 2010 Comments off

Nothings is done. Everything in the world remains to be done or done over.

The greatest picture is not yet painted, the greatest play isn’t written, the greatest poem is unsung. There isn’t in all the world a perfect railroad, nor a good government, nor a sound law. Physics, mathematics, and especially the most advanced and exact of the sciences, are being fundamentally revised. Chemistry is just becoming a science; psychology, economics, and sociology are awaiting a Darwin, whose work in turn awaiting an Einstein.

If the rah-rah boys in our colleges could be told this, they might not all be specialists in football, parties, and unearned degrees. They are not told it, however; they are told to learn what is known. This is nothing.

(Lincoln Steffens, 1931)
(quoted from How to Get Ideas by Jack Foster)

This was said about 80 years ago! Yet, it is still relevant today. This quote was something that I have wanted to tell my students if I ever get a chance to…

Create a menu for private pages and posts in WordPress | ActiveCodeline

A feature to implement. We want to have member-only items in the top menu line. I think this is a fantastic idea. We’ll do this later..


Create a menu for private pages and posts in WordPress

Posted by branko in General | 14 Comments

Recently I was working on a project that required a members menu on sidebar. Idea was to mark some pages and posts in WordPress as a private ones. All those marked as private are not to be accessible to all others, unregistered users, or even some registered that do not belong to some assigned role. WordPress default behavior for posts and pages is not to show up on menu if you are not registered user, which is good. However, another WordPress default behavior is to show only private posts on sidebar menu while logged in. Meaning that pages marked as private do not show up on the menu when logged in. This is not so good. I needed a solution that will list private pages on my menu as well. After few minutes of unsuccessful Google search, i decided to write my own solution. It really wasn’t that difficult. It all came down to two existing WordPress functions, current_user_can(‘some_role’) and $wpdb->get_results($some_query).

/*show pages and post mixed on menu
$menu_type = post ->show posts only
$menu_type = page ->show pages only


if(current_user_can($user_role)) {

global $wpdb;
$html = null;

if($menu_type != 'all') {
$menu_query = "post_status='private' AND post_type='". $menu_type ."'";

else if($menu_type == 'all') {
$menu_query = "post_status='private'";

$query = "SELECT * FROM $wpdb->posts WHERE ". $menu_query;
$pages = $wpdb->get_results($query);

$html .= '


return $html;


else {

$html = '

We are sorry, but only '. $user_role .' role user can access this area

# return $html;
return false;

Have you figured out how this WordPress works?

August 20th, 2010 Comments off

Honestly i’m a little confused. So I’m trying things out. My questions:

  • What is Category. Is it really different from tag?
  • Is there category view, which is different from menu view.
  • Is there any way to post static html page directly (not through a link)
